BLF GT w/ SFT40 !!

I think that lux reading was made from 10 meters, btw. 1.8Mcd

this is the light i was eluding to!

ill have to check his notes to me again.

I have a GT with a black flat and it is awsome to.


Nice ..

There is only one direction left to point it ....Up !

It needs like 45 layers of dc-fix

Nice, I figured it wouldnt take long for someone to do this :smiley:
Would have saved time had this LED been around when the GT was made

i don't have the original xhp35 HI version, but I have to imagine this is similar but throws further.. I think? It lights things up in the foreground too. It's amazing lol, I'll how it in beamshots, been raining for 2 nights here now of course.

I thought I was the only one to put DC Fix on a thrower. :smiley:

5 meters, indoors, using a Extech LT45. This is how I've been doing all my throw measurements, least I'm consistent with my self

The original BLF GT that I measured at 5m did 857 kcd, but I have a note that the best # I measured at 5 m was 957 kcd.

I measure throw from 7 meters normally, but have the option for 12.5 meters. My original GT did not measure more than a few percent different for those two distances (can’t remember the exact numbers). So I expect that 5 meter will get close enough numbers too.

I used the driver from the BLF GT90 conversion kit and the biggest 5050 MCPCB I could find:

Took the original XHP35-HI centering piece and opened up the hole:

Tested amps using the long leads I did for reducing voltage/amps:

Pushing the limits:

Thanks for adding that Tom!

Okay… I was thrown off here by the format Artie used. 1803kcd or 1.8Mcd back calculated from 5m. The way I read it I thought there was a units typo and it was 1803lux @ x meters, which obviously would have to be ten for 2686m of throw. Sorry gents, carry on.

yeah that was my bad I noticed after you commented. I wrote it weirdly, should have put 1.8mcd

This is a great project that I would be excited to see, if the pictures were visible! I can't see any of the photos today.

That's not a terrible thing, most of them are pretty lame. What is the beam shots are posted it will be more interesting

edit, Tom's pictures are nice because they show the inside of the light, My pictures mostly show the inside of my house. Lol

  1. I think I have the same reamer but in blue
  2. Why haven’t the SBT90.2 conversions I’ve seen used the reaming technique for a centering ring?

Dunno - maybe because it's a lot of material to ream to convert it. Actually all the stock black centering pieces had holes too big. The one I reamed for the SFT-40 was the best fit one by far. The good thing about the stock piece is it seems to center nicely aligned to the screws. The screws actually down hold anything down. I probably should have put a little dab of silicon glue on the threads to hold them in place.

Just there to prevent rotation?

Yea, stop rotation and center alignment.
