Thanks
It’s expensive though, like $500+ usually, which I could put towards my next flashlight project.
On top of that, it is like 1.5x more expensive for me thanks to the canadian dollar xD
Certainly, I will not stop until I have a non-bulb flashlight that can beat all of those short arc lights on that graph
Pretty similar to the design often used for short arc lamps:
Compared to a lens+wavien collar of the same diameter it will have less lux though, since the lens won’t have the dead spot in the middle.
The lens will also give a tighter beam since all of the points on the surface will be at a longer distance from the LED.
It’s a factory diffuser. It just clips in the grooves of the bezel ring. They work amazingly.
I call the diffused light from this a big ol ball of cotton beam, removes the hotspot completely.
I doubt it. LEDs are nowhere close to the luminance for the size of the light source as HID, though LED is likely far better when a wider view of illumination is needed. A few marine large searchlight makers use both now for both spot and flood.
Just saw this thread and i had to stop by. They are less in use due to AWWW LED’s these days but i spoke with some high end torch makers they start thinking about drivers similar to AW and AlanB regulators. I don’t have any HID but i do have dozen incan mods from 1x16340 up to 8x18650 versions.
My latest build is CPF Fivemega Elephant II with 3” head and AlanB regulator which will run Osram 64657 bulb (250W - 11000lm).
Don’t have pictures but i’ll be happy to post after i get home from a trip.
