If you mod lights you want a well build host that can handle heat. I wouldnt spend to much money on modding something like that light you mentioned. A good starting point is a convoy c8+ or a s2+.

Always good to start with Convoys, it saves you years of struggling with poor designs.

The M3 isn’t that good. Good quality, very bright but that is very short lived. The temp limit is too low and the brightness drops from 100% to a low 30% without anything in between

I bought one of these a few weeks ago from another vendor who claimed he was selling me an XHP90 for $22.00. After receiving it and measuring the LED it only measured 7mm. I cannot find a comparison photo so I don’t know if I was sold an XHP70, SST70 or something else. Tail cap current only measures 1.7volts.

It would be nice to know if I could stack a resistor or two so it doubles as a hand warmer. It has an underutilized AOD480-30V N-Channel MOSFET.

Mine was a fake xhp

It’s something like a 7070 led , not sure the name but it was quiet bright

I measured the power draw from the tail end and it was 4.5 amps

On 2× 26650 battery’s on full power
Low power was less then an amp

They are not real Cree

It’s some Chinese knock off that they called a xhp90

They are bright but in zoomables

4chip led

I’ll make some pictures and review or something in the coming days

If Cree launches the XHP90 the chances are high that you will find a thread on BLF first. Wink

I assume the XHP70 is much more efficient with a better color rendering than all of these 7070 or XHP90 clones.

Your sarcasm was well received alpg88. As P.T. Barnum said, “There’s a sucker born every minute”. My post here wasn’t my first stroke of ignorance either. I requested a refund from the user on Ebay and included the specifications of 9mm for the ghost Cree XHP90. I included an image of my led with a micrometer display showing 7mm and explained the “XHP90” should measure 9mm. I feel like an idiot however, the good news is that my insistence on the CREE XHP90’s existence won me a refund. you have to fight fire with fire. lol

i was not really sarcastic at first, at first i even thought they really made the led, then i started looking for datasheet, and then i realized it was just a name of none cree led.

Sounds like modding opportunity for me if the driver supports 12v version Wink

Though the build quality can be a concern.

 

Searching for High CRI leds since 2010...

 

Has finally gotten to the bottom after 10 years of delving deep into that rabbit hole of them high CRI lights...

 

High CRI, high quality lights doesn't need to be expensive, or is it?

Heat transfer is bad , it’s aluminium and painted where the pill should be , mods can be done with some major overhaul

Removing the NTC solves that problem
