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

OK thanks. I’ll try to get some of these. 13$ at fasttech…wow

2R and 2U would be even better.

I read somewhere that after slicing the dome, you should remove the rest of the silicone surrounding the die to reduce the tint shift in the corona. Can’t remember where I read that though. Does that make sense?,

That was KB that said that and it does seem to work for him, although I think he said that is also can tint shift cooler around the edges after doing that just to a much lesser extent?

Overall that is only for the very advanced modders among us.

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.
