Easy Super Bright Flashlight (10 watt)

I wanted to build an easy flash light that last long and super bright. 

This is what i came up with.

I found the bulb on Ebay for about $20 and found out it's operating volts are about 3.6V-4.2V and 3 rechargeable batteries are rated @ 1.2 V each but normally they run at about 1.33x3 which is about 4 V even. so rechargeables are the way to go. I didn't use a driver for this  because the volts were in range. It works good for me and doesn't get hot. Ill see if it burns out or anything in the future. This does work with 3 AA's but I wanted one that would last longer so I went with 3 D's.

Step 1 Materials

Here is a list of materials used:

New SSC P7 White 900 Lumens 10W Light LED DIY 3.6V-4.2V (ebay $20)
Rechargeable D batteries (6 for $20 on Ebay)
Used flashlight that uses a regular bulb and 3 D batteries. Free. 

Tools:
solder and solder gun 
J-B weld 
little weights to hold it together
Duct tape to hold it together

If your driving it at 10 watts its going to have a very short lifespan. I have an mce aswell as a p7 and both of those get VERY hot even with minimal heatsinking.

you need a better focus the led. the beam pateren looks terrible.

modify a higher quality flashlight. also, a t6 led is better. i bought one, they are super bright (1000 lumens) and less than 5mm square

Its not going to last long without a bigass heatsink attached to it

It didn't get hot on me yet. This was more of a test and see type of deal. So far so good. :)
