acebeam WL20 - 2000m throw

holy white laser Robin!

http://www.acebeam.com/wl20-throw-2000m

i hope they show it on IWA next month ;)

and here’s hoping you or Neal will share a nice coupon with us for this

So the W10 but with a bigger lens, cool.
Can’t wait to buy one and transfer the LED to my optofire to get 10 million candela :smiley:

PS - it is 2000m, not 5000m

i asked them this morning to clarify and the just edited...

unfortunately to the lower value :(

and i was confirmed they show it to me in 2 weeks at our appointment :D

Laser? I don’t know much about laser. Is it safe?

This sounds very Exciting looking forward to a hands on review Martin. :slight_smile:

I want this but new funds are months away, giveaway?

Martin, make sure to do a beamshot or 2 at spot setting, during your appointment, white wall and outside.

Glückspilz!

This is laser phosphor excitation like some BMW headlights, not a coherent light source. It should be safe.

Martin, check them both out.
Beam shots, we need beam shots.

Yeah they are showing them off at IWA 2018 in Germany, I already asked them, unfortunately I won’t be in europe :frowning:
March 9-12
No info yet on buying them though.

Yeah, the laser doesn’t shine directly out of the light, it shines onto a phosphor and then turns into normal white light.

Doing this with 500 lumens though this is literally going to be laser like. I can’t see this beam being particularly useable for much.

The Maxabeam on mid-mode is 450 lumens at 1 degree beam divergence. This W20 is 500 lumens at .8 degree beam divergence so its gonna be brighter and throw farther than a Maxabeam on mid mode.

No, I don’t think it will beat the Maxabeam.

The Maxabeam has a large corona. It’s actually quite difficult to accurately determine the divergence. There is a somewhat smooth transition between spot and corona.

I believe it does around 2-3Mcd in the mid mode?

I did find values stated by an employee from Peakbeam over on CPF regarding the Maxabeam:
It produces a 2” (5,08cm) spot in a distance of 30m.

The divergence only dictates the spot size, not how much lux it has.
I’m not sure how much candela the maxabeam has on normal mode, but I would estimate about half or a third of the max 12Mcd since 450 is about half of the max 1000lm, and the W20 only has 1Mcd.

Cool… I have always wondered why they dont/cant make a white colored laser. Seems like there are other colors… but not white.

As with LEDs, lasers are monochromatic. The effect is even stronger with lasers; where LEDs will have a dominant wavelength on a bell curve, lasers just produce the one wavelength. The spacing and alignment of the waves is consistent in space and time. Lasers are all about sameness.

White LEDs put some phosphor on top of a blue LED and use the blue light to stimulate the emission of other colors. On occasion, it’s a purple or UV LED. The WL20 uses a laser to excite a phosphor instead. The laser can probably excite a smaller area of phosphor at higher intensity, resulting in the crazy high ratio of candela to lumens.

What’s coming out of this thing is not white laser light. It’s phosphor light, similar to a white LED or fluorescent tube.

I’ll be at IWA and swing by Acebeam’s booth. Although I fear it will not be for sale just then.

If you give them enough money it probably will :wink:
But hey, please take some pictures of the lights!
