Found someone who also did a remote battery pack mod for the EOS which lets you use 3-4 AAs depending on the type of batteries for winter use, with total weight les than Apex headlamp yet light output higher. Pics are in the same thread. If this can be done totally waterproof in a rainstorm, I'll consider doing for our EOS. The mod lets you use it with the integral batteries in summer and the remote battery pack in winter.

Right on! Thanks EJ!

I just saw something on CP forums that said they were stait from one of the Fenix reps.

Hi Aaron,
What's the link? I saw the same thread last week, and posters said they had called Fenix and got a flat "no" from the Fenix reps.

In the meantime, I'm modding an EOS with a Seoul P4 - it will be monster bright and offer the same great battery life. It's a very easy to do modification that is relatively inexpensive and makes the EOS the brightest, lightest regulated long battery life headlamp you can get now.

EJ,
Not sure the exact link, can't find it any more.
If you got a BIG NO, them that's good enough for me.

I'll just have to get one of these bad boys for biking at night.

I couldn't deal with 21 ounces of light and battery on my helmet. If you could get a longer cable to allow for remote battery placement it might lighten up things but the four lights spread might be too wide cycling.

I bike and ski with more than ample light from an older Metal Halide model and I've been impressed by the minewt x2.

I agree with the 21 oz, but I would mount it.

I finaly came across the link
