The seller at the above link might be trying to associate this flashlight with being a LEP when it appears to be LED pumped phosphor instead of a laser diode. In the advertisement they state the flashlight uses a 12 watt LED to produce white light, but they also throw around the claim of being LEP as well as being a "laser" flashlight. When I emailed them asking if the light contained a laser diode I was rudely answered with an insult and what I believe were misleading statements.
If anyone has seen this flashlight themselves, please report what it is.
I asked them about how many lumens the WLL30 has as it states that it has a 10 Watt laser, and this was their reply.
Hi Glenn,
Thank you for your enquiry.
This Unit Produces 19000 Lux at 5mtr, which equates to approximately 2800lm at the same distance.
Kind Regards

So I sent a another reply to ask if the other LEP’s out there have a 10 watt module that only puts out 4-450 lumens then how come theirs can do 2800L? - I understand that the WLL30 has a bigger front lens and therefore maybe has a more intense beam, but 2800L?
As I’m not a maths dude maybe 19000 LUX at 5 meters is 2800L - but I know the techie’s here will know.
So I got another reply to that question:
Hi Glenn,
Thank you for your reply and further enquiry.
When comparing these units different parameters were utilised. to explain the difference please see below:-
- WLLX75 Measured at 5mtr (16.40ft) - Utilising a 5deg Beam Angle =19000lux or 2840lm
- WLLX30 Measured at 25mtr (82ft) - Utilising an Average Beam Angle of 1.5deg = 6000lux or 2000lm
Acebeam W30 Measured at 5mtr (16.40ft) - Utilising a 1.8deg Beam Angle = 25800lux or 500lm
In reality the real difference in comparison comes down to the distance measured at and the Beam Angle.
We hope the above information proves useful.

Thanks for any of you guys reply’s/thoughts/knowledge.
I personally don't know how they can calculate Lux to Lumens from a distance.
That's not how it is supposed to be done and that's not how it can be done. So I wonder what their calculation is.
Secondly, you can see that the WLLX75 has a lower Lux than the Acebeam W30, and should therefore throw less far! You can't change that.
Maybe they made a mistake? At least their calculation doesn't add up.
It doesn't matter what the beam angle is, because 19000 lux at 5meters is less than 25800 lux at 5 meters (W30). So with those numbers, it's impossible to reach 7500 meters like they advertise the light at.
But they might have accidentally made a typo?
19,000lux at 5 meters = 475,000 cd, which equals to 1378 meters... not 7500 meters.
Even if they made a typo, and was supposed to be 190,000 lux at 5 meters, that makes it 4,750,000 cd = 4359 meters. Still not close to 7500 meters.
So something is wrong.
They should follow the ANSI FL1 standards in my opinion..
But besides that.. I think it's interesting they make these lights, because a 90mm LEP is quite rare. I welcome them to keep improving them, because they look interesting.
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.
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!
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.

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.
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.
