Light Geeks: Best (High End) Regulated Headlamp on 03/30/2013 15:44:37 MDT Print View

Hey guys, I'm not up on the gear lately, but I'm in need of a new headlamp/light.

I'm not looking for recommendations from the usual "Backpacking" gear brands (i.e. Petzl, Black Diamond, whatever) unless they've finally come up with something competitive to the likes of Fenix, Zebralight, Surefire, and the rest.

I feel like I should be wanting a single AA light, but I see how ubiquitous the CR123s, ZL631s, etc, are getting. Number of output settings are a big deal, although I don't care about having a red output. Long life at a usable medium/low setting is most important.

Looking at the Zebralight page, they've got more options than ever. Fenix also.

Ideally I'd like a high efficiency, light, headlamp, and a backup high output flashlight, so input on both will be greatly appreciated. Maximum lightness is not a priority, I've got a badass walmart hat clip LED that serves that purpose. ;)

I use a Fenix PD-22 and love it. I had a Zebralight, and now use the headband from the Zebralight with the Fenix, it fits fine. On a recent trip, I had to walk a dark, unlit country road for a couple of miles and the Fenix lit the road up. In camp the lower settings are perfect, and at those settings the thing lasts forever.

Highly recommended.

That blind date didn't work out so well then, huh?

I've got a Zebralight H51 and love it. Works really well in the cold with a lithium battery, and AAs are available at any gas station. Not so with CR123s. At that end of the spectrum, most of these lights will be pretty good.

You might want to start with a target brightness in lumens, and then work your way out from there. For example, at some REI stores they have a bunch of demonstrator headlamps. Ask if you can see one of those work in the back room where it is dark.

I like my Zebralight H501, since it has a low level for max battery life, medium level, and bright level if I really need it.

I would discourage you from seeking a headlamp that requires some special battery. If you can't easily recharge on the trail, and if you can't buy/replace on the trail, then you won't like it.

Yeah, I think I'm going to try and stick with a single AA headlamp.

The battery life numbers are enticing on the odd battery types, but as you say, the lack of availability negates the benefits.

You should see the other guy . . . .

As to the question at hand, I've had good luck with the Fenix LD01. There are numerous other Fenix models, but this is relatively inexpensive and is certainly bright enough for trail or road walking. I also carry a Photon light I already owned as a back-up, which I sometimes use in camp, "saving" the battery life of the Fenix.

Looking at going with a Fenix LD12 for HL, and a Fenix PD32(T6) as a full size/backup for heavier trips.

Or considering one of the Zebralights for the HL. Any recommendation on model and flood vs non?

Going through all the data at places like CPF is eating up my productivity today, and the last thing I need is a flashlight obsession.. ;)

I know what you mean with CPF! I don't check there regularly, but have in the past when deciding to buy flashlights/headlamps. It sucks you in!

Regarding your choice of the PD32, or PD32UE - I was considering that one for needs other than backpacking, but decided I really don't want to mess around with CR123A batteries (no matter how many people on CPF say it's not a big deal). My tried and true rechargeable Eneloops work great, and AA/AAA alkalines are easier to find in a pinch. So I went with the LD22 and I've been satisfied. For my needs it projects far enough when a far-reaching spot is needed and its battery life on lower levels is great. It appears the newest iteration is even a little lighter than the PD32. I have brought it along hiking, but have just as well gotten by with the LD01 - those two cover my flashlight needs in the woods, at work, and at home.

Can't comment on Fenix/Zebra headlights. I'm fine with my BD Spot for now, though I'd like to upgrade/go lighter eventually.

I chose a floody light, not a spot beam. It works fine for normal headlamp use, but the light looks slightly more natural if you use it for night photography. The spot beam is OK, but you spend more time moving your head to re-orient the spot.

If you are looking for the best AA flashlight (not headlight) check out the Zebralight SC52 AA. I bought it a few months back and I am still amazed with it every time I turn it on! I believe it is still rated as the highest output AA flashlight on the market (280 lm) but the amazing thing about this light is it can also use a 14500 Li-ion rechargeable battery which pushes the output to 500 lumens!! The beam also has a very good balance between flood and spot. It's really nice to be able to use any kind of AA cell or the high output Li-ion cells.

I can't say enough good things about the quality of the Zebralight Flashlights. I really like the user selectable, multi-level outputs and the durable build quality. The only reason I haven't bought one of their headlights is that I'm waiting for them to make a headlight version of the SC52 AA.

I also have a Fenix HL21 Headlamp (takes a single AA) and it's a nice light (good beam quality) but the build quality doesn't compare to the ZebraLights. I also don't like that it dies without warning... the regulated circuit in the HL21 headlamp is great (keeps the brightness constant) but there isn't a battery indicator, so it just dies (bright one minute, dead the next... won't even turn on). The Zebralight SC52 AA mentioned above has a battery test that lets you know the condition of your battery. Nice to have some warning.

I also have the FourSevens Preon P1 (single AAA battery). This is a very nice light if you are looking for a small, light weight handheld flashlight for everyday carry or to slip into your pack as a spare. Nice build quality and a very nice beam for a single AAA ...and so tiny (.8 oz includes a lithium AAA battery and pocket clip removed)!

CPF on 03/31/2013 06:49:05 MDT Print View

CPF can be a soul crushing experience - take it from me I've been sucked into that vortex for too many years!

I currently have two Fenix lights - an E01 which is still a great compact keyring light, and a rebranded Leatherman CR123 - probably a PD of some flavor. I owned a couple others. They are well built lights but I've found for me there are two issues with most Fenix lights that I'm not crazy about. The first is they mostly used a "reverse" clickie switch which I don't like - I like being able to press the clickie a little bit for momentary function and then lock it if I want to keep it on. In day to day use the reverse clickie just doesn't work as well. Their basic user interfaces also either start in medium and/or have strobe or SOS built into the sequence. I don't need strobe or SOS so I mostly avoid those lights and I really have a decided preference for starting in low or being able to start in low. Now those are very specific nits - after too many years tinkering with lights I have however figured out what works for me so I'm just sharing those but fully recognize many don't care about either of those issues! Fenix has a dedicated and well deserved following for built quality and keeping up with technology so if you pick one you won't be disappointed from that end.

I use a Zebralight H31w and I love it. The UI is pretty good - you can start at either low or high and there are a lot of levels to choose from. They are also well made in my experience. No momentary option of any flavor as they use an electronic switch - but it works well and reliably.

As for batteries you have to make some choices... a while ago I settled on mostly CR123 based lights. But I was a flashaholic before a backpacker - so while battery availability is a piece of the equation it doesn't necessarily drive it. From a flashlight perspective there are just more better options in the CR123 format when you start exploring higher end lights and the CR123 format allows for a smaller light with more oomph than AA (which needs 2xAA to achieve the same voltage output).

So you need to evaluate what fits your usage. I have not as of yet done a lot of long trips - none really - nor night hiking. Putzing around the campsite I mostly use low and sometimes medium. You'll get a good bit of runtime off one battery and CR123s are small and light - so I haven't had availability on the trail as a high priority item. Certainly for a couple weeks out it would make sense to rank that higher, or if you hike in the dark a lot (and are using higher levels longer). But on low I have a couple lights that will run for a few weeks - one for more than a month - on constant use (now that is a low low mind you but with adjusted eyes it is plenty of light for most basic tasks).

Just a few things to ponder when considering battery choices...

AAA lights on 03/31/2013 08:15:12 MDT Print View

I don't really like headlamps. So I prefer to use a flashlight for more trips. Given the power and efficiency of the best lights these days, I find it hard to justify anything more than a AAA light. The amount of light they produce and the runtimes they achieve are amazing. I have a Klarus mi10, which may still be one of the most impressive AAA lights, including 45-60 hours of runtime on an quite useful low. I don't have this one, but the other AAA light out that looks very attractive is be the Olight i3s:

That starts on high mode. But offers 10 hours on medium/low and up to 120 hours on a low/moonlight mode. Plus it has a reversible clip.

All single AA LED Flashlights are regulated on 03/31/2013 10:29:31 MDT Print View

All white LEDs need about 3 volts to function. The AA battery puts out 1.5 volts. In order to get the AA valtage to the 3 volts requires a DC to DC converter is required. All DC to DC converters regulate the power to the LED. So all single AA powered white KED flashlights are regulated.

However using a single AA battery and a regulator does come at a cost. The maximum run time is limited to about 2 hours maximum bcause of the rate the power is being pulled out of the battery. Most other flashlights or head lamps use 2 or more batteries in series to get at least 3 volts to slow the power drain from the battery. A 3AAA battery 100 lumin headlamp will go a week or loner on one set of batteres.

What you should really do is first determine how many hours of operation you need and how much light. Once you settle on that then look at your options. Give what you have said so far a single AA flashlight may be what you need. However there might be a multicell headlamp that will meet your needs as both a headlamp and as a standalone flashlight.

Re: All single AA LED Flashlights are regulated on 03/31/2013 11:25:58 MDT Print View

That's good info Steven, but it's not helping me from going info-overload on CPF, which has taken up my morning already. ;P

Ideally what I want is a good flood with high run times on medium/low (i.e. able to work around camp comfortably) settings, at a good weight to runtime ratio. Regulated output regardless of batteries is a must, I wasn't aware that all AA lights were regulated, but I am aware that most AAA headlamps are not.

I will couple this with a compact but high powered flashlight, since I often do heavy night hiking. I've been forced into multi-hour night time egress on multiple occasions.

I'm willing to go with non-standard batteries for the flashlight, as I don't think it'll see more than a few hours continuous use on a trip, and would rather higher output and run times without carrying extra batteries.

I used a Petzl (Tikka XP I think?) for years, and hated it, it's crap for hiking at night, crap for working in camp, etc.

I'm not sure the right solution honestly. Since I cut my hair, I'm able to wear hats, and usually do when hiking, but I also use poles, so I'm not sure how well I"m going to be able to hold a light and hike, but I also don't like wearing a headlamp to hike, glare bothers me, and I'll often need/want to be wearing a cap.

Anyway, I'll keep researching.

Check out budgetlightforum, a bit more friendly than CPF.

For a high power light you'll be looking at an 18650 light.

A good set up would be something like a C8, with the modes:
moon, low, medium, high and a turbo 3 amp for short periods.

Headlamp wise, maybe worth giving an ultrafire h2b a try. They aren't amazing but coupled with a high power torch I find I'm pretty much covered.

Re: BLF on 03/31/2013 11:51:43 MDT Print View

I'll check out that forum, thanks for the recommend.

I just had my mind blown by the realization that a light with a 90 deg cast with a clip on it can be easily clipped to the pack straps or your belt for hiking however, and the Spark SD52-CW is starting to look like a winner.

Someone at CPF mentioned that it's a great flood with the normal lens but can be replaced with an optional lens easily that gives a nice throw for night hiking.

I think coupled with a high powered torch, this might be my head-lamp, but I'm concerned about the weight. Not sure if there's another comparable single AA option.

There were 2 "maximum"s in there, and I think he meant when the light was running at maximum output. The zebralights are nice because they give you the option of trading light output for runtime. More so than most headlamps, which offer 2 or maybe 3 settings in a much narrower range.

I got an H51 last year and would never go back to the ones I used to use.

Just my opinions.. on 03/31/2013 13:06:58 MDT Print View

I'd go NW not CW for a headlamp, you loose a little output but colour rendition is far better.
I'd look at budget alternatives to spark, they are great lights but for $100 you can likely find both lights that will fit your needs.

A nitecore hb02 headband would allow you to mount a small 18650 based light on your head/cap for the ultimate runtime and amount of light.

I use one, with a $15 torch modified to moon,low,medium,high and can therefore run for days on moon or a couple of hours on high with enough light coming out to light up 100m in front and have a whole group follow.

I'd consider adding two pieces of elastic to a cap that could hold a small light, such as the convoy s2, or roche f12. Therefore creating a holder for only the extra weight of the elastic. I'd then think about adding a layer of clear coat or spray to the lens to create a diffused beam. You then have a light more powerful, and less weight than alternative headlamps on the market.

That coupled with something like the xintd c8 would cover any night hiking I would feel comfortable with, and they both run on 18650's...which as far as I'm aware will give one of the best power to weight ratio's of any battery suitable for a headlamp.

"Regulated output regardless of batteries is a must, I wasn't aware that all AA lights were regulated, but I am aware that most AAA headlamps are not."

Another thing about LEDs is that they run at constant brightness as long as the voltage is in spec (3V). Go over it burn out. Go below they dim rapidly. So well a 3 AAA battery headlamp may not be regulated, it will for the most part produce constant light until the voltage drops below 3V and then you will quickly notice light drop off. My Princten Tech Fuel might not be regulated but with over 100 hours of stable light output I don't bother bringing a spare set of batteries most of the time.

In the past regulation was a bigger deal because most LED lights produced less than 40 lumens of light and it would be difficult to tell when they started to dim. but with many now over 100 lumens you will notice the drop in light output With a regulated light one of two things will happen when the batteries are fully drained. 1 the light start to flash until it goes out completely or 2. it just goes out with no warning. I would rather have one that gradually dims while hiking than one that suddenly goes out.

As to the comment:

" This is totally false.

I was reffering to 100 lumen output. On a single AA battery most manufactures list about 2 hours on high. I am not awar of any manufacutes clamming 3 day on high with a single AA. At low output, about 20 lumens or less, 3days might be possible but at that level you probably will have difficulty following the trail.

"So well a 3 AAA battery headlamp may not be regulated, it will for the most part produce constant light until the voltage drops below 3V and then you will quickly notice light drop off."

That's not been my experience with the non-regulated 3 aaa headlamps (mostly petzl) I've used in the past.

I notice the change in brightness very quickly, and while they do last "forever", find that the vast majority of that "forever" is at well below the stated lumen output level.

Maybe if I always ran on low it wouldn't be an issue, but once the drain starts being noticeable, the low modes are now too low to be useful.

Another thing that bothers me about it is working in 3s, 3 alkaline triple a's (~34g) is fine but I've got to have 3 more to replace, and I find it easy to get the fresh and drained ones mixed up, 3 double A's weigh about the same as 6 triple a's, but that's two backups, which I often wont need more than one if at all looking at the numbers on something like a Zebralight.

Looking at the numbers on some comparable regulated high output lights that use either 3 triple a's, or a single double a, at the same ouput levels, the math is showing me that the double A's come out very close, depending on the LEDs.

Yeah, I'll be changing batteries more often, but in this scenario it seems more versatile to me.

Right now I'm leaning towards some Zebralight floody, with a backup high power torch, I like the Spark SD52-NW, *but* 4.2oz for the package with an eneloop, having to use two batteries in it, the ZL H502d High CRI Daylight tint AA Flood, with two eneloops would be 3.8oz.

It's a hard decision though, as the Spark with the extra lens would allow me to leave the flashlight at home for lighter trips, and supposedly has a more comfortable head-band, but is an ounce heavier on the head, and would require lens changing for hiking with it, and more fiddle factor likely.

I am probably going to go with an 18650 powered torch, but don't anticipate taking backup batteries considering the run times. I want the extra output and the long single cell run times, but will likely never drain one on a short to medium length trip.

Does anybody else know of a lamp like the Spark SD52-NW that can easily convert from a full flood to spill or spot beam, in a single AA format or a lighter overall package?

Zebralight and beam/ tint on 03/31/2013 17:55:58 MDT Print View

I own:
-A Zebralight H51. It has a floody beam with a well blended hotspot, so it's great for walking at night but still very usable for reading a book. I use the 30 lumen mode for walking and the 2 lumen mode for reading.

-An H51w, which is the warm tint version of the H51. the tint is nicer on the eyes, but I find that I need to use a higher mode when walking at night. The cool tint of the H51 just seems to give more clarity, even if it isn't as easy on the eyes.

-An H502D, which is a full flood light with a tint that could be described as halfway between the H51 and the H51W to my eyes anyway. The full flood beam is great for reading, but I need to run it at the level two of the high mode if I want to walk around in the dark. This means that for wandering round, I burn through the batteries much faster than I would the H51.

-A Surefire E1L. This takes one cr123A battery and has a full spot beam. It's only use (for me) is occasional use to check ahead for where the track goes. Full spot is not very useful for me and hard work on the eyes for anything up close.

-A Fenix LD01. Nice beam with a smooth transition between the spill and the hotspot. The tint is more blue than the H51 and it runs on a AAA, which means the medium (which is what I used for walking at night) doesn't last as long as I'd like.

I don't think it's a good idea to pick lumens first and then beam pattern. If I want to walk at night, I'll want a floody beam with a smooth transition to a hotspot, so that it can give some distance. If I tried to use a full flood beam for this, I'd need to run it at full power.
30 lumens with a hotspot is the same percieved brightness/ usefulness as 100ish lumens of full flood, for me.

Lux is a better indicator that lumens for night walking (for me).

Surefire Minimus on 03/31/2013 21:54:47 MDT Print View

I've completely switched over to CR123s - far more energy dense [i.e. lighter], don't leak, have a shelf life of 10+ years, and function wonderfully in cold weather.

I've had a Surefire minimus for about 8 months and it's been excellent. It's robust and the potentiometer allows the user to dial-in light from 1-100 lumens and anywhere in between. The beam is quite diffuse - I've found it fine for backcountry use and even downhill/backcountry skiing at night [i.e. complete darkness] with zero issues light wise. 100 Surefire lumens is a lot different than another company's 100 lumens. I have Petzl lamps that have a higher-output on paper, but there's no comparison with respect to light quality and intensity. Definitely worth serious consideration.

Thanks for all that info A D

My original idea was to have a full flood for camp chores, which is why the H502, but I get what you're saying, and if I'm honest, I'm not sure what I'd like really. Unfortunately, most of the info you read on places like CPF is hyper subjective, and idealistic. High CRI, warm tints, throws, etc, not much evidence on how those opinions relate to our use.

I may pickup a H502 and a H51 and see which I like the best. I'm also ordering an Eagletac D25LC2 Clicky, as a backup flashlight. Although I may end up with a combination of H502 flood for camp use and a H600 for night hiking, or something even lighter for camp use and the H600.

Honestly avoiding the light obsession isn't working out, just too many f'n options.

Edit: Not sure which emitter I'll go with on the Eagletac, gotta do more research.

Light Geeks and CPF vortex of time loss on 04/01/2013 18:00:57 MDT Print View

Like this thread because I have been wanting a new HL for a while. Very good info.

I started at the Zebralight site. Had looked at those previously. I love their comparison page with a the spreadsheet. I like the right-angle beam and form factor. I was first looking at the H51 because of the the Eneloops I have around. Then I was intrigued by the H31 with the weight savings and smaller form factor. Started (first mistake here) looking at output ratings for the H600...damn that's bright, and the runtime is amazing. Started looking at options for 18650 batteries (second mistake here) and followed a link to CPF. After three days I have emerged even more confused than before.

I recently did a late night hike bailout with a Petzl e+lite. It was ok because we were primarily on a road, but it did leave me wanting more light. I had a Fenix LD01 (EDC) on the keyring in my pocket but I use poles and didn't want to hold it.

There are several 3400 mAh 18650's now available. Is it worth the weight penalty? Is it worth buying a new charger? I think i would use a higher setting in many tasks and when hiking just because I knew I wasn't running the cell low.

Any other 18650 users out there have opinions?

PS. I have blocked CPF at the router level and only my wife has the password. That place is dangerous...

Haha this may happen to me also.

Anyway, I pulled the trigger on a Zebralight H600w today. I decided that instead of going with a primary light that used a standard battery configuration, I'd go with something high powered, with numerous modes and insane runtimes and output. It's a bit heavy, I figure 3.6-3.8oz for the package, but I wont be carrying extra cells for it.

For a backup I'll have either a single cell AAA or AA light (I'm leaning toward the Eagletac D25A mini (0.77oz without a cell), which is single AA and has outputs high enough, and run times long enough to cover a pretty serious bailout if I needed it, which I'll put a high capacity lithium primary in (Energizer Lithium AA 0.5oz)

My current Petzl Lamp weighs 3oz with Alkalines in it, could drop it a bit with lithiums, but a set of backup cells would be another 3/4oz in lithiums, so I'm at nearly the same weight primary, with 10x the output potential, many more modes, huge runtimes, fully regulated output, better color rendering, the ability to clip to my pack straps for night hiking, etc.

I'm also expecting I'll enjoy the beam quality a lot more, since I can't stand the Petzl's color, spill/spot profile, and glare.

I'm fairly certain I'll be able to work up a diffuser for better flood profile in camp if I feel I need to also.

In the end, I'm not saving weight, but I don't think I'm adding it either. I am losing the ability to find a battery at a gas station if I forget to bring one, but that's a risk I'm willing to take. I am however I think, increasing versatility, utility, and user happiness, god willing. I'll add the redundancy back in (which a single headlamp, regardless of battery type doesn't have if it simply fails) for the 1.25oz penalty, of a backup light with a standard battery type.

I've got plenty of room to add back in utility and still maintain crazy low baseweights, so the marginal net gain looks like a win to me here, and I've got other options for SUL/XUL pack lists, but those arbitrary number exercises no longer hold much appeal for me.
