My Survival Lite and Trek 7 finally arrived today. Took about a week and a half, from Glow-bug. That's with Priority Mail. I'd called them earlier... I was told their shipping dept. is running behind.
These two lights are definitely brighter than the Trek 2's and 3's, brighter than the 4-LED Lightwave... and I think they may be brighter than the Eterna-Lite.
I'm amazed that the Survival Lite is as bright as it is, given that it only has one teeny-weeny LED embedded in a circuit board, behind a magnifying lens. It's a little less bright than the Trek 7..., but significantly better than the 4-LED Lightwave. It's beam, though, has a bright, circular light pattern, with a large, less bright center.
The Trek 7 is a large, fairly heavy flashlight.. about the size and weight of the old-fashioned 2 D cell flashlights I had as a kid. And it's about that bright.., but with a nice, diffused beam.. a little brighter in the center than further out.
The Trek 7 is a bit too heavy to include in my bugout pack, unfortunately..., and extra, rechargable C cells would add even more weight.
The Survival Lite is nice a compact, and only slightly heavier than the Lightwave..., but most of my solar chargers don't have a 9V battery option.., plus, I'm trying to standardize on AA batteries..., so it probably won't go in the bugout pack, either.
So I guess I'm still gonna end up with the Eterna-Lite and the Lightwave in my bugout pack.., and I might throw in a Trek 3 if I have room and can afford the weight (the weight of the flashlight is relatively negligible... and I'll have the AA batteries already).
