3 X P7 Surefire KT4----Turbohead----

[DaFABRICATA]

This one has been in the works for a while now. I am using a Shark to drive these for the time being until a better Multi-P7 driver is available.

My mill is not working at the moment so everything was done with what I had available. Caveman style. I have a ton of scrap metal laying around and used some 3/8" aluminum for the main heatsink- (not sufficiant for long runtimes) and I used some of what was left from one of my "Ribbed For Your Pleasure" bodies to house the driver (Shark) and also extra heatsinking as well as a pedistal to allow battery contact. Also Tig welded onto the sides of the old "RFYP" body are some ears for screwing to the main heatsink. I also used another tower module heatsink with the smaller top portion cut off to extend the (+) positive contact. Like I said I was using anything and everything to make this work. The P7's are run in series. I used Mcr27XR reflectors that give a very floody beam. It figures I finally get this done and it's light out. I'll have to wait till tonight to see what its like outside in the dark.

- Surefire KT4 Host
- 3 X P7 Emitters
- 3 X McR27XR Reflectors
- Shark Converter
- Custom heatsinks

Should have paid more attention: glued the emitter on the wrong direction

And finally the beamshots.

I am looking forward to giving these P7's more power.

The P7 is a lot bigger than a P4... three of the P7 emitters is physically not possible to fit in that head.

Re: 3 X P7 Surefire KT4

toby pra- The Shark is working fine,I just want more power.



Milky and Manzerick-

Re: 3 X P7 Surefire KT4

Beamshots added-


I am very interested (excited) to see what this turns out like when these LEDs are given the power they can handle. It is very floody and bright, but not enough power is the current hold up-



All camera setting were set the same for each shot and the camera mounted on a tripod.

Judging from the beamshots, the P7 with modified McR38 gives a nice beam with decent throw and spill.

Certainly more throw than the KT4 head.

What do you use to enlarge the hole in the McR38?

I used a Uni-Bit drill bit to open up the reflector hole.

The Mcr38 really does do a good job with the P7.

The single P7 light using the Mcr38 is running at 2.8A. The KT4 is being seriously underdriven at maybe 970.mA. So there is a lot of room for the KT4 to get really bright, I just don't have a proper driver for it yet. I had a chance to use them both in an open field last night and the 3 X P7 KT4 is brighter and has about the same throw as the single P7/Mcr38 light.

Strange that all that light didn't spook the donkey:nana:

Nice work:thumbsup: I can't wait to see the 3XP7 KT4

Updated Beamshots in post#1

Well, I originally (like a dumb ***) didn't check the voltage in my MB20 and had depleted cells. Using a Fivemega 3 X17670 battery carrier helped A LOT!!

Just check out the beamshots!

 

[toby_pra]

This looks amazing...:devil:

Frigging bright...:naughty:

 

[DaFABRICATA]

It was foggy out this morning so I decided some more beamshots were in order. These show how the beams look and how tight the E2DL is compared to the Floody 3 X P7 KT4.

Nice work dude!

These might be under-driven, but that also means that they are running more efficiently (less de-rating from heat), and of course give you better battery life. It is a "very" nice compromise in my book
