Will this bulb work in a Tec 20? Well I know it will work, but what I mean is have you tried it? The height of the bulb needs to be just right to get the reflector to work properly.

I've gotten the best results with the MAG LITE, 2 'D' cell. Because the focus can be adjusted, it can have a tightly focused beam. I've tried it in unfocusable flashlights, and it is only okay.

This is an attempt to post a photo of the Luxeon PR base emitter I have made. It is up on eBay. Do a search for "Luxeon" and you'll find it.

Luxeon PR base emitter
Hmm, I would like one of these to stick into my Dorcy Blue. As the light takes 4 AA alkalines what kind of resistor would I need to stick on that so I wouldn't fry the Luxeon. Sorry I'm not electronics savy, but I can solder

I put an emitter in a 4 'D' cell MAG LITE, but it has lots of heat sink. I used 5 ohms, and probably could have gone down to 2 ohms.
Using this PR base, which doesn't have much heat sink, I would think that you would need 10 ohms resistance? to reduce the current to 300mA or a little less. Otherwise it might get too hot.
Also, without being able to focus the Dorcy, I am not sure what the beam would look like? I made this PR bulb specifically for a 2 'D'
cell MAG, which can focus the beam to a tight spot.

You can replace one of the batteries with a dummy cell containing 2.5 to 5 ohms resistor. At 2.5 it will draw 300+ma on new batteries, but in few minutes will settle down to 250+ma, at 5 ohms, 250+ at first, 200+ in a few minutes. At 2.5 ohms, things can get hot, 5 ohms things get warm.
Personally, I'd go for like 3.5 ohms and test for heat. Decide what next from there.

You could just use/make 2 dummy batteries. Then run it staight from the remianing 2 "real" batteries.
I replaced one of the batteries with a ~3 ohm resistor. Works really good with rechargeable or alkaline batteries. I did find that the original dorcy reflector wasn't much help so I used a faceted reflector out of my Sears tool light (same as dorcy boss). Now I have basically a super Turtle Lite II. Works really well and this type of reflector really minimizes the green in the LS.

I have a few emitters left, I can make a couple more. I wasn't going to make any more, but if people are interested, I can. I just auctioned one off on eBay. Gandalf won the auction.
He sniped it up within 6 seconds of closing!
Wooo Hooo!
Email me if you want one.

Hmm I've been away for a while and I'm just getting back on track of things. Ok on my earlier question about putting this LS in a Dorcy Blue with 4 Alkalines a couple people suggested putting in a dummy battery or two.
Again I'm not up on my electronics theory, but is there any reason that I wouldn't want to use 4 batteries? I assumed I would get a longer burn time on 4 batteries instead of using just 2 or 3 with dummy batteries. Thanks

You can run 4 AA's if you use some resistance. I usually use 5 ohms resistance. However, you must have very very good heat sinking. This PR Base Bulb is back at my house for repairs. It burned out, even using just 3 volts. The emitter separated from the small heat sink. Bother.
This was won on eBay by a fellow CPFer, and it burned out after 15 minutes.
If you do something like this, you cannot overdrive it, and it may or may not provide enough heat sink.
Thought I might mention this in case someone else tried it.

The one PR base emitter, pictured in this thread, burned out after 15 minutes. The emitter separated from the heat sink, and overheated. That was a design flaw. So I'm repairing it and sending it back to the owner. Hopefully this doesn't happen again.
This PR base Luxeon Star bulb was designed to go with only 2 cells, because of limited heat sink. It is not real bright at 3 volts.
If you want brightness, you'll need to use 3 batteries, and possibly modify your flashlights similar to the 3 cell Mag conversions I've done.
I also did a conversion with a bare emitter, in which I mounted it on a aluminum stud which was pressed into a heat sink, and pressed into a 4 'D' cell Mag Lite. It is really bright, and throws a good beam a long ways.
I haven't done many mods with the bare emitters because they take so much work to do. I have been using the Luxeon Star with optics.
