I’ll be sampling this LED on Friday when I meet up with some other CPFers for a night hike.
The host is a harbor freight 109 LED showerhead, 4xAA, DX-SST90 reflector. The XPG2 is direct bonded to copper and running at around ~2-3A.
The lights owner said its a ~6 month collaboration with the Lambdalights dude.
Craig has these on 20mm stars, I am thinking about modding my MXDL-SA76 with this LED. It should drop right in, with maybe a little dremel work to the star. Currently with the XML at 2.8A its in the 45-50K lux vicinity I think, and very closely matches my 3.5A-HD2010. I think an XPG2 upgrade should come close to double that.
Oops… I miss-quoted from my email exchange. The light does 2-3A to the LED. Sorry about that.
OTOH, the lights builder does some AMAZING things with copper fabrication and direct bonding. This builder was doing things with copper ~2 years before anyone else on CPF would even consider trying it. I would be surprised if it tint-shifted, or thermal-dimmed significantly. I’ll see on Friday!!
2-3A? Now I really can’t wait to see what Match gets on his bench test of this LED! I’m expecting around 600 lumens when overdriven considering the 1st gen can break 500.
Thanks for the heads up on that. I’ve been wanting to get an XP-G2. KaiDomain was so quick to have XT-E’s available and I hoped they would come through, but with this board I can put together my own P60.
If you test the new XP-G2 please share with us the vF of the LED for each current that you test, like jtr1962 did on CPF . Yes the vF will be influenced by the junction temperature and will not be a data 100% applicable to flashlights, because it will change depending on the MCPCB size and material.But still a valuable data.
Just completed a XP-G G2 drop-in driven off a 3X 7135 board, beamshots to come (comparing it to an identical XP-G G1 drop-in).
By eyeball: it is quite a bit brighter at 50mA (need to get my DMM out to confirm they are pulling the same current on low) then the XP-G, at 1A slightly brighter and tighter hotspot.
EDIT: OK… the drop-ins pull 10mA difference on low: the original XP-G pulls 40mA while the one I just put together with the XP-G2 pulls 50mA, this would account for the visible difference in brightness. That aside both pull a little over 1A (XPG = 1.04A while the XPG2 pulls 1.01A) and the XPG2 is brighter once thermal sage takes its toll on both (I think the XP-G2 is sagging less)
