acebeam WL20 - 2000m throw

I’m sure that LED manufacturers (even those with experience in laser technology) present laser diodes with excited phosphor in one package in the next months / years. Maybe they look the same like the LED we know and maybe they could also easily be reflowed? I remember that Osram presented such a concept some time ago…

One company introduced this quite a while ago: http://soraalaser.com/products/

Laser Focus World – 22 Feb 17

Laser Lighting: White-light lasers challenge LEDs in directional lighting...

Legacy halogen and metal halide light sources can produce highly directional beams, but with low efficiency and short lifetimes.

The blue in the middle just seems like chromatic aberration.
I’m not sure why there would be a blocked hole in the center, it is an aspheric light not a reflector light.
They may be using a phosphor with the laser diode placed behind it, which would require a piece of light-absorbing material directly in the center of the lens to prevent laser light form leaking.
If the center of the lens is blocked then that would create the “hole” that you can see in the video, and regular chromatic aberration would make it look blue.
At farther distances this hole and the blue tint would disappear.

The light is fixed focus single mode. Chromatic aberration is pretty significant. Could see no hole though. Tint differences were visible up to 20-30m. As it was indoors I could not check further distances.

i was not impressed by the laser lights tbh...

What’s the practical use for a beam profile such as the WL20?

Pöbel · 2018-03-12T09:23:57.000Z

Sometimes things are only done because they can be done. Most of us do have many lights with zero practical use

M4D_M4X · 2018-03-12T09:25:32.000Z

no one has seen a beam now, only a spot in a bright exhibition hall.

i could imagine one would like to mount that on a rifle?

btw

the GT made a brighter Spot ;)

Pöbel · 2018-03-12T10:29:42.000Z

did you bring your GT along? I thought about it, but did not want to haul that huge beast along all the time just to stomp the WL20

on the second day..

got a lot WOWs ;)

It’s hard to really tell for sure, but it appears to have very little spill.

The_Driver1 · 2018-03-12T16:46:17.000Z

Aspheric lights don’t have real Spill. Only the light reflected off of the internals of the flashlight exit the light as Spill.

Should be a kind of corona so, unperfect collimation of the light. Spill is direct light from emitter, isn’t it?

No.
Corona happens to reflector flashlights that have a gradual decrease in intensity around the spot.
Aspheric lights have only a spot, no spill or corona.

I know that cprpna heppens in reflector flashlight cause of the led is not a source perfectly fitting the focus point of the paraboliod.
If the focus is in the center of the led, every other lighting source os not collimated to the distance, so that it’s created a corona.

We all know that WL20 has not any reflector…but someone saw a light around the spot.

SPILL THE BEANS!!! Tell us what did you see!!!

Acebeam has other interesting lights

You are kidding right? Or maybe not :question:

Even if you are not hunter get yourself lets say 6x mag monocular and pair or mount 1mcd flashlight on it and you’ll see things you did not even noticed before.

Imho there is nothing more impressive than super thrower flashlight (laser or led).
Especially if it is available in small, light and portable configuration or if you have zooming flood to throw ability. I would never ask for better light.
Lumens can’t impress me unless they are accordingly followed by lux. I have 20 000 + lumens street light in front of my house and I only have headache from that

M4D_M4X · 2018-03-12T20:38:02.000Z

look me in the eyes Baby!

taken from the W10
WL20 looks quite the same , but with bigger Lens (NOT zoomable!!)
