I've been thinking about how to do this with my craftsman. I figure just trim down a PC heatsink to fit in the head and wire together 5x Cree LED's in series should take care of it simply. Each should get about 3.6V and you would have a killer pure flood beam.

I did soemthing with a Ryobi 18volt. I used a 3023-dn-1000 buckpuck to power 4 XR-E's in series. i opened the head ans stuck in a CPU Heatsink and drilled holes for air.

There's one in my school workshop, I *think* it just uses something similar to a maglight bulb; maybe one of those conversion maglight bulbs would work?

However, I think that would create more throw than flood, which is what you'd most likely need it for.

Not here. I generally use mine for flood light when working on tasks around the house. Even if it is basically a Maglite bulb, you have to be careful to get one capable of being supplied with 18V. Otherwise... :poof:

THIS IS WHAT YOU NEED TO BUY ITS A DROP IN FOR ALL 18VOLT FLASHLIGHT SYSTEMS. GOT MINE A FEW MONTHS BACK, ACCIDENTALY LEFT MY RYOBI IN ATTIC FOR 2 DAYS FLASHLIGHT WAS STILL ON , IF IT WAS THE REGULAR BULB IT WOULD HAVE LASTED ABOUT 4-5 HOURS AT MOST.

TerraLux used to make an 18V drop in for Ryobi, Dewalt ect, 18V lights but, I cant find it anymore on their website. They must have discontinued it. :ohgeez::shakehead

I owned 2 of the TerraLux 18v led conversion kits and both of them burnt out after 4 to 8 hours of use in my Ryobi work light. I’m assuming this was par for the course with that product, witch most likely lead to it being discontinued.
I like the arrangement AardvarkSaugus suggested with the 5x Cree leds, but also with a voltage regulating chip similar to those in several of the Princeton Tec Headlamps; I think that would make for a very solid product.

I've just received a led conversion for my Dewalt DW919.

http://cgi.ebay.co.uk/FUSION-48-LED...aultDomain_0?hash=item19b95ef08a#ht_500wt_956

and some more info from the manufacturers website

http://www.sinounion.com.hk/product2.htm

Overall a nice floody beam with a reasonable hotspot, about what you would expect from 48 5mm leds, just about right for a work light. Tint is surprisingly white and much better than the yellow awful beam of the original incan bulb and reflector. Input voltage is 9 to 18 volts so I might end up using my 14.4v Black and Decker drill light to get more use out of it. Lumen wise it is just as bright as my Sgt Burkett P7 driven at 2amps with a medium boom reflector so I’m guessing around 400-lumen ballpark. If it is a true 4w module then I’ll be getting around 10 hours from my 2.4amp hour battery in the Dewalt, might have to take it camping in summer.

Damn, that's super interesting. By the way, it's also available by someone on the american site, not that it matters since it ships from HK.

Don't suppose you have two dewalts you can do a side by side comparison?

Could you do some runtime testing with this module and the regular bulb for us?

Also, does it just pop right in?

Thanks

It just pops in, the hardest part was teasing out the stock reflector without damaging it just in case i want to put it back. Once the retaining ring is screwed back it makes the module snug and very secure.

I'll see if i can get some beam shots and post them, maybe even get my multimeter out to take some readings. As for run times i'll have to wait to see if i'm free at the weekend.

It looks and feels like a nice little bit of kit for the money, some nice finning at the back of the unit should keep it cool in the plastic housing.

Very cool. No rush on my behalf, whenever you have the time. I'm all spent out right now anyway :)
