Krill Lamp 360 Extreme (what I ordered at least): Green and Red. <www.kriana.com/>
I've mostly used these to attach to my backpack to wear while running, but not impressed by the "extreme" label. I'll need to hunt down the packaging again to confirm if extreme or normal, but the glow is overall dim and needs to be in a fairly dark environment to be noticed. The Glo-Toob is a little brighter, but doesn't have the nice even glow the Krills have.. Plusses are it uses the super common AA batteries and are fairly light (before batteries) and durable. Makes a good low-viz light in night/dark activities since the dim glow doesn't blind the user.
*Update- I've found the extreme model to be as bright or brighter than a classic chemical stick. I wish the ends were easier to twist. I know they need to prevent accidental discharge, but damn I can barely turn it it on/off barehanded since most of the krill lamp is slick plastic. Having grip relief on the top/grey area would be helpful like they have on the main bottom/cap. As a work around, applying a simple lubricant to the inner cap area works well.
