Acebeam W10 1000m throw EDC???

That is at least pretty cool!

Im buying one if it’s a basic colminated laser. Me likey. Me like a lotty

Hmm… This is very interesting. Coolimated white laser?
I really imagined that one day we will have small ultra throwers plus ultra flooder in one small package that will look exactly like this flashlight.

Now if will they achieve 1000m in laser pointing style it will suck, also diffused laser beam looks kind a dirty.

My hat down if they managed to make something good out of it but by judging Laser Genetics flashlight models it will less likely to happen.

That goddamn fugly reversible strike bezel thing really puts me off.

A white laser flashlight with 1000m throw? I’m intrigued! :sunglasses:

What you are talking about is called (laser) speckle. A Phosphor converted blue laser shouldn’t have this (or at least much weaker).

Thanks for clearing that out. Yes speckle I usually see with IR laser lights looks dirty comparing to led IR lights.

If they manage to improve that it seems we will step up into the laser flashlight future.

Simple phosphor target lit with a 445nm laser diode insted an blue LED
Maybe they even found a OEM module used also in BMWs or other cars laser light headlights

Of course with laser you can get a smaller emitting area like an LED
phosphor stays cooler

So you think it is a laser-excited phosphor rather than an RGB laser or something? If it’s an excited phosphor the light would be diffuse and would need to be collected by an optic of some sort.

Pretty cool if they can get 400cd/mm^2 luminance. I’m not up on the state of the art; what kind of output are people (like BMW) getting?

I have 2 Acebeam lamps. EC50GENII and EC60. Both are perfect. Very strong light and small enough to keep in the pocket. Nice design, best quality.

It’s probably indeed a blue laser shining onto a phosphor. Pretty impressive for the price actually. I would not assume it’s an RGB laser as A. Those are way more expensive for this output and B. Those have very, very bad CRI (think negative). Even with a phosphor converted blue laser, the CRI will probably be not that good. Still interesting nonetheless

BMW does around 500cd/mm^2 in the actual headlights. They can’t go higher because of regulations. In the lab they reached a maximum of 3000cd/mm^2, but they don’t say at what power consumption and what kind of cooling was necessary.

Laser diodes are more difficult to cool than LEDs. They don’t tolerate as high of a temperature.

EDIT: here is the link to article on the BMW headlights regarding their luminance values. Additional information can be found in this article.

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.
