Hey,
I'm at it again. I got this small Ultrafire U4-MCU Cree Q5 flashlight, to Mod a P7 emitter into it. The light is 5" long and the head is 1 5/8" in diameter. It takes 3-AAA batteries or 1-18650. I don't have any Li-ion, so I'm using the 3-AAA even though I won't be able to push the P7 to 2800mah. I will only push about 1000mah with the Tenergy batteries I have. I'm hoping whoever buys this later, will use an 18650, so the emitter will get pushed closer to full power.
Here's a couple of pictures of the light before the mod.
Now, here's why I am using this light. It has a thick aluminum head and the Reflector is Solid. Not a thin reflector, but a solid chunk that fits snug into the head. That means it will be able to take the heat of a P7 much better. Plus it's got a glass lens.
OK, so I'm just changing out the emitter. I'm using my infamous Copper heatsink and mount for the emitter.
I'm not going to go into all the details. I took out the "pill" as shown in the photos above and I made a copper HS to replace the brass one. It's thicker than the brass one and it fits tight into the bottom of the reflector.
I mounted the P7 onto the HS and used Teflon wire and Artic Alumina adhesive. I used the original end cap over top of the HS and made a Positive contact in the center of it. I made a ground right to the HS. It all fit in the bottom of the reflector and I used thermal grease when I slid it in the reflector.
I used thermal grease on the reflector when I slid it in the head and slapped it all back together. Here's a picture of the emitter in place and the rest are Beam shots, before and after.
The beam shots aren't much. I just took a couple of shots with the camera set on Auto, in the bathroom. Yes the bathroom....
Original Q5 emitter with 3-AAA batteries.
Again, the Q5, shot at the ceiling vent.
Now the P7 with 3-AAA batteries.
and Again the P7 aimed on the vent.
Ok, so I wish I had an 18650 to see what it would look like. Already it's much brighter than the Q5. It didn't get hot at all, but I think that's because of only having the AAA batteries. 3.6v but only 1000mah.
So there it is. I will put it up for sale right away. I'm doing three different flashlights to make and put up for sale, it's the only way I can afford to get a few bucks ahead and make what I really want for myself.
Have Fun!
