acebeam WL20 - 2000m throw

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

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

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 ;)

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.

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!!)

More importantly for me, it means being able to see further down a passage. Even super throwers like the GT have enough spill to blind me. If this illuminates nearby objects far less than any zoomie, then it’ll be a big win for it. Given the rated throw with such few lumens, I’m expected far fewer lumens spilling outside of the hotspot. Sometimes only illuminating what’s hit by the hotspot is desirable.

Uh, no, corona happens in reflector flashlights because the distance from the LED to the reflector surface varies largely.

A lens has all the refracting surface at almost the same distance from the LED.
Of course it depends on the lens F number though, but there is close to 0 corona compared to a forward-facing reflector.

Any “spill” people re talking about is simply tray light that is not collimated properly, this happens with even the best aspheric flashlights, there is always a bit of light reflecting around on the inside.

Um, I’m thinking we’re soon going to have to start worrying about retinal damage.
