XHP70.2 P2 4000k Output test by Texas_Ace - it's over 9000!! lumens and still going strong!

Because of the precision needed or what do you mean? What if I remove in safe regions and leave a bit of safety margin?

Yeah, it is very easy to mess it up and kill the LED. Removing only some of the phosphor next to the die I don’t think would be worth it but I have not tried it myself.

You can always try it and see what you think.

Guess I’m in the for the risk, as soon as everthing arrives. At the end of the day, it’s just a dead emitter. :money_mouth_face:

Era of dedoming and slicing will be over sooner than you think guys :+1:

So what’s the upcoming Era about? Glueing silicone domes on domeless LEDs? :smiley:

No…
They will simply look like this:


Hi ladies/gents,

Looking to update one of my lights with MT-G2 emitters.
Looking to go 3000K or 4000K, 80 CRI min.

Seems like XHP70.2 is the obvious choice. Any recommendations?
Has anybody tried the 80 CRI variants from Kaidomain? Looking to avoid the XP-G3 high CRI puke Green effect.

As for beam quality, will the beam suffer alot going from MT-G2 to XHP70.2?

Thanks

I tried one of the 80cri 4000k LED’s from kai and it is one of the best tint XHP70.2’s I have tried.

The beam should be tighter then the MT-G2.

Thanks Texas_Ace

Any donut hole? or is the gap in 70.2 close enough to be a non issue?

That will depend on the reflector / light but as a rule you will just have a slightly dimmer spot in the center, no hole to speak of.

One last question, is the XHP70.2 LED voltage of 6V or 12V dependant on the MCPCB layout?

Yes, all the LED’s themselves are the same, just the mcpcb that changes.

amazing, thanks so much!

Hi everyone, I’m new to this forum, I’ve seen this post, I’m looking for a driver project to power this wonderful LED, I have to be able to power it with both 2S and 3S batteries without losing the power of the LED, you know how to help me

You will need a buck driver to do that. It could be hard to find one as there are not a lot of options.

Maybe contact Lexel, he makes Buck drivers, but I dont know if he makes them work with dual input voltages. Maybe.

I need the circuit diagram of the driver because I have to be able to draw the pcb on a specific drawing for the torches that I have created, I don’t like already made pcb

I doubt anyone will share proprietary designs with you. Maybe you can reverse engineer an existing design. Then you’d need to create or adapt your own user interface. Sorry, I can’t help with that.

All of lexels Buck drivers I have seen are based on the BLF GT buck driver that Del designed. Del posted the schematic somewhere along with the firmware.

Lexel beefs them up with extra components to get around the ~5-8A limit that the base design has according to Del.

Looks like the images for the test are not displaying any more.
