After reading Adrian's reply above I dug out my Fenix LOP SE light. I think this came out about the time Fenix was introducing the LOD line. I think the SE version was regulated and had 3 light levels unlike the regular LOP which I believe was unregulated and had one level. So, anyway, I dug it out of my gear box, went and bought a Li AAA battery and modified a Photon clip to fit the light. Total wt. with battery and clip = 27 g, e+lite with batteries and also with modified Photon clip, = 21 g.
So, yeah, it's heavier, but only 6 grams. ( I know, a gram here, a gram there, it's a slippery slope.:-)) Well, I am going to give the Fenix a try and see how I like it. I found the eLite to be adequate, but as mentioned if you use it on high for more than 15 minutes you will suck those pour little button batteries down. It will not do as a headlight for very long. I'll see if the Fenix can do better.
