There are actually a small minority of BLF’ers that can use a good thrower like this. For the rest, it’s just a toy. I don’t have any use for a thrower, but I’m definitely impressed by the reach of these things. I’m not a flooder either, though. I prefer a medium size hot spot and a decent amount of corona, with very little spill. Some of my favorite lights are TIR.
I’m working on one!
Thanks! <3
Yeah mostly for fun, it’s like a fat laser with a very visible beam that isn’t dangerous to the eye and can’t cause fires.
At 1 or 2km the spot is large enough to light up a house, so even though you can’t see very many details from that far away you can still clearly tell that there is a house, without using binoculars.
Your vision is better than you think, look outside, you can still see stuff at 5, 10, 15km away.
And I might consider buying it 
Well, not yet…
And many light-years away. too!
hahaha true!
Nice!
A flashlight with a Noctua fan...
It would be interesting to see how much relative output the LEDs looses over time due to heating up.
You monster. I’ll have to keep my eye out for a build thread 
Ah true, I could take several lux measurements over time.
When I did the intensity measurement I waited a few minutes before taking the final reading.
It’s impressive to see what you can do with only 3 screws.
Isn’t it this one ? : Received the second component of my future project
Yeah I haven’t had time to machine the piece of metal I need to hold and cool the crystal and laser.
Hopefully once school starts in september and i have access to the machine shop again
That’s pretty slick! Like a laser beam!
Thanks
I like fat lasers
What’s the power output on the led, like volts/amps?
It’s running at 6A and about 3.7V, so ~22W
With three high capacity 18650s it would run about 1 or 1.5h on max
That’s a lot of power through that tiny led! Good to see it’s fan cooled.
Ok now that is ridiculous
It’s not much compared to the 200W that the CFT90 was running at in my syniosbeam build 
thanks
You are one crazy dude Enderman.
Keep it up. 
Thank you
Enderman i have some questions for the throw master. i know that the collar directs the light back onto the led but does depth of field and size of the aperture have anything to do with throw?
Do you think the collars could be made by cutting a hole in one of these Aliexpress with a diamond hole saw?
