The flashlight in question was a gift from a co-worker who bought several of them on special off the Mac guy many years ago, when 45 lumens was quite impressive.
It was my primary flashlight for years... until I started my flashlight addiction, now it just sits around. I started taking it apart and this is what I found:
The number on the back is 2706LXHLMW1D. More info on this can be found here: http://www.luxeonstar.com/Luxeon-Star-LED-White-Lambertian-45-lm-p/lxhl-mw1d.htm
I'd love to get this light up to around 150 lm or so. More is always better, but I don't want to get to extravagant on this old light.
It's powered by 3x AAA cells in series and according to the website draws 350 mA. The website says these are no longer available (duh), and suggests a SR-01-WC310 as a possible replacement. The SR-01-WC310 shows 350 mA putting out 135 lm, that's pretty close to where I would like to be. My problem is, the LED base/chip is surrounded by plastic. It sits on plastic, it has two plastic pieces that fit around the edges, there is a plastic ring that goes over top. Heat looks like it would be the limiting factor with the current setup. should anything that draws 350 mA or less be fine?
2nd, this appears to be wired direct. I see no other circuitry on the board other than the LED. I can only assume there is something limiting the current under the emitter. The existing setup is listed as 350 mA, the SR-01-WC310 lists it's output at various currents. I assume that means this is not internally regulated and is going to need some additional circuitry to prevent burning up the LED. Am I correct in this assumption.
I don't have my heart set on the SR-01-WC310 as an upgrade, I am just using it as a jumping off point to get the ball rolling. Other suggestions are very welcome. As you can probably already tell, I'm not extremely knowledgeable on this topic, I understand electronics fairly well and am handy enough with a soldering iron, but have never done a flashlight mod other than just drop in types.
