I just received the L10 from SBflashlights.com It's made by L3 Illumination and has gotten fairly good reviews on by CPF and Budgetlight forums. It runs on a single AA battery. You have a choice of emitters: the Nichia 219 (it's a neutral tint, versus the "cool" or "warm" of other LEDs) or the XPG2, which is a brighter output with a "cool" tint. The Nichia 219 is a neat tint, but I don't get enough of a benefit from the change in tint to really care, so I opted for the higher output. The Nichia 219 is also a couple of bucks more; I bought one for a friend and she loves the neutral tint. You also have a choice of three or four modes (disclaimer: data copied directly from the website, including the lack of runtime on "medium"): Four modes of output: firefly(0.09lumens 147 hours) Low (3 lumens, 30 hours) Medium (30 lumens) High (120 lumens, 1.5hrs) (Tested with Ni-mh battery with actual capacity 2500mAh) Three modes of output: Note: 3 mode model removes Firefly mode of .09 lumens. Low, Medium, High only. Personal observations: I bought this mostly as a toy; I was curious about the "firefly" output level and I like having a long-running AA flashlight, even though I'm mildly famous for my intense dislike of multi-modes. I haven't had a chance to abuse it yet, but for $19 + shipping (the whole thing was roughly $22, I think), it's still a good buy even if it can't survive extraordinary abuse. So far, I've been pleasantly surprised. The firefly mode is absolutely functional for maneuvering through a dark house, or reading labels. I could probably navigate a bay full of sleeping troops, but fortunately I haven't needed to test that one. Once you start using the firefly mode, the "low" mode seems insanely bright. Cycle up to the full "high" and your reaction is a whole lot of "whoa!" The tailcap is particularly noteworthy - it achieves both a secure anchor point for split rings while still keeping the tailstand feature. Fenix lights (the E01 and E05) put the split ring in the lip surrounding the base. The L10 actually has a nub inside the lip with a hole to accommodate a split ring. Personally, I think this is just cool. The flashlight body is perfectly smooth, so you have no anti-roll features. You can buy a clip for $2.50 when you order your light. The clip snaps on to the body - it isn't loose, but it isn't secured enough to clip outside your pocket, either. But it does provide a measure of anti-roll if that's your thing. I'll try and get pics up tomorrow just for sake of completion.
