Finally! PT-54 Flashlight

[yobresal]

I put together this little PT-54 Red LED flashlight tonight. It is running between 6-7A direct drive. This light is brighter than my single P7 at 1A. It should be putting out 600+ lumens but I cannot test this. I'm just going off the spec sheet which is now MIA. It runs on a single LifePO4 18650. This thing is just insanely bright. On with the photos.

My room with the lights on

Lights still on....

Next to my P7 @ 1A

How'd you get such a good beam profile? I'm using my original reflector, but I also put a lens in it to give a reasonable throw distance, but I get an odd beam profile ..

 

[yobresal]

I have a VERY deep and wide reflector. It really shapes the spot into a perfect circle. The bezel in front makes a weird shape up to 3 ft away but past that it is a perfect circle. Came out nice.

Awesome. I also am very impressed with the sweet looking output.:beer:

What kind of driver did you use?

 

[LaZeRz]

^didnt you read? its direct driven

anyway nice build, any links to that host?

Also doesnt that thing heat up like crazy???? running at 8amps in the c@s10 projector it needs a huge heatsink with TEC's and fans

 

[yobresal]

Short duty cycles. Just like a laser. The host is pretty hefty and the entire head acts as the heatsink. The pill screws tightly into the head of the host.

 

[LaZeRz]

name of the host?

 

[yobresal]

Don't know the name but here is a picture and link to one.

That is some crazy bright red flashlight Yob.

Nice

 

[lazeerer]

Sweet. What battery are you using. 6-7A.

 

[yobresal]

LifePO4 18650 rechargeable. This is to keep the voltage down (they are less than 18650 Lithium Ions) and to keep the discharge capacity high.

 

[Lotus_Darkrose]

You should do a small run of 5-10 of those. Bet they would sell out.

 

[yobresal]

I'm sure they would. Id need to switch to a $30 host instead of a $70 one. Even then with the host, Led, and battery I'd probably have to charge $100 to cover shipping, paypal fees, and still make it worth while. It took a bit of time getting it together. I'm building a green one and a blue one as well. The green should be out of this world in brightness.

Can't wait for those, that will be awesome. Matching set I assume?
