Please ask them if the phophor is pumped using an LED or laser diode, or both.
From their description: Blue LASER, axial optical setup (LASER - Phorphor - Optics), “independent measurement” of 19klux@5m.
That’s 19000*25 cd = 475000 cd = 1378.4 m.
Not sure what the 1 lx thing might be, they’re writing about. Could be the 1.3 km is the distance to produce 1 lx on the target. That would be quite good I guess, but they should be more clear about it.
Might have to take one for the team - worst case scenario is I hate myself - or… I go, I now have the cheapest furthest throwing LEP! (you gotta admit the icing on the cake is the Rear Military Tactical Tail Cap Switch :0)
Still can’t get my head around the numbers they quote, unless as I have read some places that 10 watt lasers are only really making 4-5 watts in LEP lights - so maybe the laser (osram) they are using produces the full 10 watts. Still the 5deg vs 1.8deg angle is messing with me.
Can’t see Osram 10 Watt diodes in blue mouser
- WLLX75 Measured at 5mtr (16.40ft) – Utilising a 5deg Beam Angle =19000lux or 2840lm
- Acebeam W30 Measured at 5mtr (16.40ft) – Utilising a 1.8deg Beam Angle = 25800lux or 500lm
Well I’ll just stay happy with things like this cute baby
Seems to me they are using a 10W blue LED, they say as much on their ebay listing and probably throw in mention of LEP or laser to help sales when they shouldn’t. The beam has the appearance of being a LEP but I believe this is due to using a transmissive phosphor target which has a similar beam pattern. If only using a LED with a broader beamwidth, it probably has half the throw of a W30.
This is Laser Project, I lost my password and tried to recover using a different email address without realizing it, or remembering I had this account from 2014 first.
I'm very curious as well.. thank you for taking one for the team :)
The ebay listing warns the head cannot be opened without destroying the light, the LED hidden from external view?
If a member buys it and can somehow open it or see what is used inside, I will donate 50 dollars via PayPal for photo’s of the LED or laser, if it has one inside. If you can’t find me active here go to laserdiscourse.org to find me there as “laser project”. This offer only good for just one individual.
Yes I ordered it, I’ll try to get a looksee down the barrel. I have many throwie lights +have had many Aspheric lights - I also have a Acebeam W30, so I know what a LEP beam looks like. I’ll do a beam comparison for Youzers!
Great, if you want that 50 later after getting it and figuring it out, just PM me.
If it feels worth it to you.
I just like helping my BLF bro’s/sis’s if I can.
Wish I could have deducted the charger and batteries for a discount as I have way batteries and charger, probably will use 21700’s anyway if I can.
OK, just got it and some day time observations. it doesn’t seem to throw farther than the W30 outside against a wall at 30 meters (day time) defiantly not 2800L - but will get back at night time with comparisons.
Build quality is maybe one step up from trustfire/ultrafire/buttfire/scumfire etc.
It is a LEP, lenses are plastic.
Cooling will not be a problem as there is tones of mass/fins.
At this stage would I buy it again - NO!
Wondering if driver could be over driven then maybe it would be better.

That definitely is a LEP module inside though
Are you able to post beamshots, wallshots and maybe measure the lux at 10m or so?
Thanks for sharing.
Do you have any size comparison pictures? Like this one next to a W30?
Great photo’s, but due to the ebay listing specifying there was a 10 W LED inside, I’m still wondering if this is a true LEP flashlight or not. Wondering if there is a way to see without destroying it, the listing indicated it could not be opened without doing so, sadly.
Did you see the pictures in post #14?
To me that looks like 100% an LEP
I’m still questioning if this is a real LEP or not, whether a LED is pumping that phosphor instead of a laser diode. The phosphor and mirror setup could be the same as a LEP and use a tightly focused LED instead. Would that produce as tight a beam output? I don’t know.
Answer me this, why would the listing on ebay say this flashlight uses a 12 watt LED if this is a LEP flashlight? Also, why is the seller so slippery in his response when asked if this uses a laser diode inside? I smell a fisherman’s market near by but would love to be wrong.
Edit: I just looked at his listing, he changed the listing to specify the flashlight uses a 10 watt blue laser diode, before his edit, he had 12 watt LED. Might it be this seller just didn’t know the difference?
I don’t see anywhere in the listing where it refers to the use of an LED. It does make several references to the laser.
Judging from the information in the listing and the photos posted above, I don’t see any reason to believe this is not a true LEP light. The range specs in the listing do seem pretty unrealistic.
Heh, well, I just edited a line into my previous post the seller changed the listing from 12 watt LED to now specifying 10 watt laser. I have a screen save of the original listing showing what it was before, if you want to see it.

It was probably just a typo, since the rest of the listing makes multiple references to the use of a 10W blue laser diode.
Was there some other reason besides that one instance of “LED” that leads you to believe this product is in some way a deception?
How could writing the flashlight “uses a 12 watt white LED module” be a typo?
Also, when I contacted the seller specifically asking if it used a laser diode and not a LED as his listing also mentioned the word laser in it, he did not directly answer me, just insulted me as not being the caliber of customer who should buy his product for asking that, and referred to the unit using “LEP technology”, never answering my question yes or no, instead choosing to obfuscate with that answer?
Also, as best I know, there are no 12 watt blue lasers available for use in this product (especially at the price offered, two diodes could be combined, but not at this price) unless he is telling us the total power consumed by a 8 watt output laser diode set to a lower output which would be a misrepresentation the Chinese like to use on their ebay listings now, calling their 8 watt output lasers 20 watt, which is the power input, not output.
This is a very fishy listing, all together.
It’s about as fishy as any listing for one of those 10 million lumen flashlights that are everywhere on Ebay.
It looks to me like this is an authentic LEP light, although probably not the highest performing one you could get, and certainly not worth their asking price IMO.
