Hi, I'm really new to this and have a maglite flashlight I wanted to modify to use a led. I want to put a really bright led in it and I was wondering how accurate the specs on these are?

Thanks

Well it's certainly impressive for a 10mm... I've seen them up to 1W though, that is a 0.3W.

The 10mm case has little ability to dissipate heat. Even at 100mA it's probably going to have a really hot die which is inefficient and degrades in a lot fewer hours than it should.

Also the focus is pretty wide and the typical reflector won't be able to tighten it.

That's why the Cree/SSC/Luxeon/etc stuff was created. Much better design. Not very expensive either.

Holy something that smells bad. I didn't see the price when I posted the first time. You are way better off getting a Seoul P4 or P7 or a Cree MC-E or XP-E. For the price of one of those things you could get a quad die LED (P7 or MC-E) that will put out about 30x more light. Don't bother with that thing.

If you want to modify the maglite to LED, I'd suggest trying to find the right a drop-in first. If you can find it then look into modding the light. Look here.

I'd ignore the 5mm and 10mm LEDs. Most of them have similar output. The 10mm ones just have a narrower beam angle. Highpower LEDs can be quite a bit brighter then the 5mm LEDs. On average it might take 40 or more good 5mm/10mm LEDs to equal the output of a single current gen high power LED.

I tried a 15k mcd 3mm led and it really isn't much brighter than the stock krypton bulb.

I want to try a high powered led but I'm not sure how it works and I also can't find one that would fit my flashlight. I saw a lot of mods and they always involve placing the led onto a pcb. What's it for?
