Thanks a million everyone for the feedbacks. I'm going to watch this thread as I think there is something out here for me. I only hope that it puts out a decent amount of light and that I can afford it. I feel like a lion that is keep watch of it's prey, and just ready to jump in for the kill.
This is one of the big reasons why I like the Arc-AAA, as it is regulated to a resonable degree, it uses cheap power source, and the light is affordable. I only wish there was something like this in a multi LED light.
Yes, I'm bias to multi LEDs as opposed to a single bright LED. It's claimed that LEDs are supposed to last 11 years, but I've seen more than a few to start flickering or grow very dim. I hate to be in the middle of my task and have my single LED start to play a number on me. My Arc-AAA is my general purpose light (because it fit anywhere), but if I need to do some serious area lighting, out comes my LW4000. If one of it's LEDs were to go on me, I still have 9 more to go. I just have to tolerate the slight dimming effect, but it's not too bad for several days of running at least 4 hours per night (no battery changes). I have about 60 hours of intermittent run time on first set of Copper Tops, and my LW4000 is still bright. To not disappoint myself, I have not changed the batteries to see how much light I have lost. I would think it has lost between 20-30% of it's brightness. But, it works for me and I'll cross that bridge when I lose my lighting upwards to 50 feet. For $50, this does the job.
I do admit, having a fully regulated light does stir my interest and I'll keep reading to see what you folk can come up with.
As an observation, can the DC step-up inverter keep up with the stated 11 year life of the LED? A case in point, my four month old CMG Infinity is in the shop with an inverter problem. CMG said that the LED was OK, but the inverter went bad. No need to answer, but something to think about...
