There are ceramic adhesives which are used in bulbs because of low thermal expansion at high temperatures.
Just because it is “ceramic” does not mean it is solid like a rock.
It can be made into epoxies or other stuff.
This is the same thing as the 2mm white flat (CSLPM1.TG) but with a larger thermal pad for better overdriving capability.
There are no MCPCBs for it yet, hopefully LED4power will make some.
TBH I don’t think it’s a viable source.
But it is a source which is a small step towards general availability.
Though now that I think about it - I remember when Hank managed to source a batch of old XP-G2 long after they were unavailable.
From memory - 1000 was sold very quickly with several members buying hundreds each.
Boost HX is likely to stay the throw king for a while so it makes sense to stash them if GB promises a lower price than a store would. Though better bins may appear.
Agro, if the Boost HX turns out to be the next throw king, as the hype suggests it will, then 2000 pieces in a BLF group buy would be pretty easy to do for sure.
