Ha Chibi, nice round-up, and could you add kcd to the table above?, throw distance is not my COT.
Celebration notice: I just bought my first LEP flashlight, the NealsGadgets LEP, with the code NDNA it came down to 152 dollar, and the favorable current exchange rate made that 131 euro.
Great thread.
I have some general questions about LEPs.
I see lots of places call them “white lasers”. I’m assuming this is untrue and that the light emitted is not actually a laser beam and that it is just using a laser to generate the light. Could someone confirm or deny this assumption?
I’m also interested to know more about how LEPs work. there seems to be very little info that I can find on Google. As a secondary part of this. Why are they all fixed beam focus for throw? Could they not be zoomy lights or even use other forms of optic or reflector?
I have found this somewhat confusing picture on the Acebeam site (a site calling it a white laser……) :
Out of the two examples above, I have no idea which way the W30 is constructed. The left hand image is reused further down the page on their website, so logic would suggest that is the construction. But if so, why have the right hand image at all?
On a separate but related note, why are there no LED lights using the optic structure as above?
Thanks.
@CD, you are right, the pump is a blue laser, which is aimed at a bit of phosfor, just like a led, the resulting light is incoherent in random direction, just like a led, and can be made into a beam by an optic, just like a led. But because in all LEP lights that I have seen the phosfor is illuminated from the front, with a mirror straight above the phosfor (so a bit different from the Acebeam drawing above), I think that a zoomie is difficult because that little mirror will interfere with the lens when zoomed out.
Updated!
The Nealsgadgets LEP is definitely the cheapest for its size. I wonder if I should add my own measurements as well, because some claims are a bit off.... so to say. The Jetbeam M2S WP-RX never reaches 1800 meters/810 kcd
Well, I know a bit about how it works the laser is directed via a mirror in the light to a surface made of phosphor which causes the molecules to get “excited” and emit a blindly bright white light which then is focused with a convex lens and projected outward.
Well in general these lights are purpose built for throw with little spill, would you be willing to shell out upwards to $400 for a zoomie with only 500~ lumens at max ? When a generic zoomie costs around $10 or less. For why it doesn’t use a reflector is it physically would require more space and then factor in focusing it via a lens would make it even larger so kind of pointless.
djozz - seems like a good decision. that NealsGadgets LEP sure does look interesting, as simple and 'classic' as it is (lack of regulation, modes, easy dis-assembly, etc.). Based on Marco's review, it appears capable of hitting 1000 kcd on a good cell, like a GOLISI 26650, 25S, or VTC5D. Wonder if further tweaking would bump it up, but not sure of the risks.
Ooops, I see vinh sells them with 1.1 Mcd performance already.
Wow this is awesome thanks for the great reviews and comparisons.
I have the Acebeam W10 gen 2 and the W30. Should I buy any of the others do you think or would it be better to wait for the next leap in the technology?
The guy who built some of my lasers offered to build me a 50 watt laser rifle that used mirrors and stuff to combine the beams from multiple diodes. I wonder if you could do something like this for LEP…
If he is capable of doing that, he might be capable of building his own high power "white" laser flashlight! I'd be very interested in his outcome.
Yeah man how sweet would that be? He made me a 6 watt blue laser that lights stuff on fire and can burn through dark metal. Runs on a pair of 16340s
pretty cool... at least ask him if he is interested :D
There’s a dude on YouTube (styropyro I think) who built an actual white laser. It combines a red, green, and blue laser to make a white beam. It’s crazy
Spelfoutje in de titel, dicuss moet zijn discuss
What exactly are you trying to do that isn’t available from these LEP lights? I don’t think you can beat the cost from these mass manufacturer. I have picked up the laser pointer hobby many years ago, and I can say that the pricing of these aren’t like LED at all. anything custom and fancy won’t be “budget” friendly.
vinh’s modded is too good to pass, thanks for the heads up.
thanks! updated.
And I found a few more in the OP :-D
Hmm… good question. I’d love to buy another LEP light just because I love buying toys but I’ll obviously want it to be better than or at least different from my Acebeam’s which I like quite a lot
I started out with custom built lasers but lately I’ve bought from companies like Sanwu

Just took my W30 out in the snow. The beam looks super cool - if I flick it fast it looks like a giant wall of sparkly light
Does anyone here have information about this product? I heard that Martin from M4D M4X was trying to get one to rewiew his channel. Does anyone know anything?

That rt. angle light looks pretty low end - poor specs. Think I looked at lights like this on Ali a while back - too low end to bother with.
I understand, but in the specifications it seems to me that it reaches 8km! The W4 says to arrive in 2.6 km …. What did I miss?
uhmmm … i saw it now …. i had to edit …. it says 20,000 lux …. really low ….
