I have several of these lenser lights, in fact the 3aaa luxeon power chip was my first 'bright' led light (the one with the side switch), and I liked the clean brushed steel look of them.
When the 1aa David light came out I bought one just before my Fenix L1P and really thought it was a contender...but.
Most of them have declined over time and with regular use, My david light showed bad wear and tear on its finish very quickly-the prominent stippling on the side soon lost its colour and looked OLD.Now it doesn't work at all and I can't find the reason why.The switch still seems to be OK so I guess the led must have been very overdriven and blown.Not good for a light only a few months old.Others have dimmed with use.
Not the worst of my collection but not the first I would pick really for any thing at all. I have given several away without any pangs of loss.
The teeny tiny 3v lithium pencil lights are about the only ones that have withstood the advances in other manufacturers lights, but the cells are hard/expensive to come by.
I shan't rush to buy another one, but to each their own.
Tempus fugit!!
INOVA is cheaper (even here in the UK) and though not as varied, is a much better bet. None of my INOVAs have declined at all even in their finish, which is extremely fine indeed. And as for my two ARCs (AAA-P V1 and +4), they are just lovely.
You gotta take the rough with the smooth I suppose.
