Multiple lenses system ? :face_with_monocle:
Even in multiple lens systems the throw is determined by the surface area of the largest lens, physics is merciless!
FU MAP lights.
1000M = 250 000 cd
~1.25” head
That would require over 400cd/mm^2 which is not possible with any current LED.
If they used a wavien collar style retroreflector that would only need to be 200cd/mm^2, which is easily possible with a black flat.
Also, the 1000M could just be part of the name, not the actual distance.
Maybe the clip is the size of your fist and it actually runs on 16 X 18650s and it’s actually got a huge head and it’s all an optical illusion!
Acebeam MAP pricing aren’t that bad, they just don’t allow for lower prices to be publicly shown, but some shops let you submit your offer and they will give you the lowest price possible. Last year I purchased my L30 considerably cheaper vs MSRP, which I didn’t believe it was possible.
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.
