Acebeam W10 1000m throw EDC???

I wouldn’t be surprised if they reached the peak luminosity in a short blink, so cooling was probably not necessary. Unless they kept one or more elements at sub-ambient temperature.

For sure is withe laser tech. Check this out. released a variety of laser searchlights last year. skyrocket prices of course.

There is not a lot of useful information on that site. The lights look very big, so the lenses used are very big. It’s very possible though that their numbers are accurate.

I guess this is the future of flashlight emmiters

very interesting!

thanks for sharing :)

What kind of efficacy can you get from a laser + phosphor pair?

I think they can do up to 30% wall plug efficiency without the phosphor. I guess now you can use numbers of a power LED that is available in blue and white to get the efficency using phosphor on top (you can also factor in that the phosphor is probably running at high temperature and thus lower efficiency).

I don’t hink it will be worse than our power LEDs at maximum power.

But our LEDs can be powered at less than maximum power leading to much better efficacies.
So the laser based lights will very roughly halve our sustained lumens while offering several times the candelas. Good, but for now not universally good.

They fill a much needed niche.

I feel that niche! :sunglasses:

Not those LEDs which have a high luminance. Those are the only ones which are in any way compareable to a phosphor converted laser.

Acebeam updated the stats on the page for the W10:

300Lm

High energy laser excitation phosphor produces white light

10,000 hours of service life

visible spectrum full coverage, no infrared and UV components

Class 3B

250000cd

angle :3degree

135G 150MM*25.4MM*33MM

1*21700 Battery 4800mAh

So it’s a class 3B laser that outputs 300 lumens of white light with 250k lux throw. With a beam angle of 3 degrees this is obviously only suited to looking at things very far in the distance (or for short ranged use as a pointer). A removable diffuser to allow the light to be used at short range might be nice.

^ very very cool specs. Any price idea yet?

I’m interested just because…

I'm interested

199$

250000cd? This means 316m of throw… Nowhere near 1000m. If true I don’t have any interest in it.

According to FL-1 standard throw distance is √cd at 1m/0.25 because it considers throw distance the distance the light intensity will be 0.25 lux, wich is ridiculous.

But every flashight maker rate their products according to this imperfect standard, so does Acebeam.

Sorry all, my mistake. I typed one zero less :frowning: 250kcd corresponds indeed to 1km throw. Interested again :slight_smile:

Ansi numbers are valid only at darkest nights with no moon, stars or city light… 250 kcd would be around 500 meters in most night conditions.
