The LEP Flashlights discussion thread - discuss LEPs here

Lasers, or LED lasers, are always fun

I love the skylumen lep. Mid size and fun for fine tuning the semi zoomable head. Very blueish white beam. Even impressive up against the mighty w4. Not as intense and focused though. Don’t know how sturdy it is. Dropping or percussion, ip test. I like mine too much.

I wonder if he sells drivers so we could do a quick swap or flash to that ui. That driver is a nasty multi layer one which might make flashing difficult along with lack of source code.

Edit: vinh said he’d try to source some drivers alone. I don’t think the driver adds a brighter turbo mode, but instead gives more lower modes.

Maybe Neal will get some though we’d have to bug him extensively to have a chance of making it happen.

I was wondering if there was a downloadable ui swap. (I’ve had pedals and such…) Mine from Vinh has low, hi, slow strobe and sos. I can’t imagine squeezing out any more cd in turbo mode. Low is 900m, hi 1800m.
Not to sure of the accuracy of that but if it was getting better numbers I would maybe want the upgrade to turbo. Or quicker strobe would have been nice. Either or it’s beast and if not there is brighter lep and other options.

I’m waiting for the first LEP-throw/LED-flood combo to appear. i.e. the new (extremely ugly btw) Olight Marauder 2 should have been made with a LEP unit in the center instead of a W2 led.

Okay, as per request, I opened the Jetbeam RRT M1X raptor up.. hope you like it, and that it was worth it, because it's broken now. EDIT:

Found the culprit..

It's the white wire going to the body of the flashlight. Didn't tighten it enough.... seems like.. now working again

Fortunately, the review was already done before this happened.

thanks for sacrificing the light for science (for now).
So this is a laser after all but the phosphorus is in fact backlit?

If the Laser is focused sharply on the backlit phosphorus this could mean two things:

- if the phosphor breaks, what type of beam would we receive?

  • mabye the sub par performance is due to the laser not being perfectly concentrated on the phosphorus but rather slightly before or after it. This could definitely decrease throw and maybe also lumens

Thanks a whole bunch for the photos Chibm! That is curious. It does not look like the usual laser diode. Closest I could find that looked similar were Some Mitsubishi diodes Laser diodes don’t really look like that with the two prongs sticking out but it does look like the laser is lighting up the phosphor from behind.

Maybe that’s what laser diodes look like if you take off the silver coloured casing shown in All these photos

I don’t quite see how the most recent photos line up with the phosphor patch visible in the earlier photos though
Edit: new photos added which make sense

Not sure, but maybe you are right Pobel.

The 4th image shows a black tube like thing, that goes between the dome/phosphor and the laser.
Maybe that's how you can finetune it....

In terms of Amps, the RRT M2S and RRT M1X have the same measurements.

I’m sorry that the light is broken :frowning:

So indeed where is the yellow phosfor disc located in these latest pictures?, is it at the back of the lens in the WBL10 part?

Fixed it.. one of the screws wasn't tightened enough.

Added 1 more picture

In the middle of this thing is the phosphor.

This is the backside.. the middle is the yellow stuff

Unfortunately, because of the flash I used, the yellow reflected the flash so you can't really see the yellow color.

So the phosphor looks very much backlit. I do wonder what that means for thermal conductivity of the phosphor and what happens if it does burn up. Will you end up with a coherent blue laser beam shining out of your laser?

I would suppose you don’t, as the laser should be focused tightly on the backside of the phosphorus for minimum spot size and maximum intensity

That’s not something safe to do on your own. If anything fails you’ll have what’s likely a naked class 4 laser shooting out the top of the light

absolutely. I’m 100% with you. The mirror design is safer than this solution, but maybe this one is easier to produce or more efficient. there surely must be a benefit (für sacrificing fail savety)

Still, a naked class 4 laser which is not tightly colimated is better than a colimated laser :zipper_mouth_face:

this product surely will probably not be legal in many places

Yes, but because it is not parallel but highly divergent, 99% of why lasers are damaging is not happening, it is not more damaging than a blue led with the same radiometric output (pretty bright though).

Damn, RRT M1X performance on high sucks big time!

I looked up t2 laser then after I saw this video. The color beam is very similar when twisting the focus of the skylumen unbranded. What is the little wedge reflector in the center of the traditional lep made of? Anyways - YouTube

What does laser etching control software have to do with that LEP lights? Edit: looks like that’s the name of Jetbeam’s new laser module
