Now, these are the best deep and far red LEDs from Luminus (better than Cree equivalent), and you already have a recent driver for low Vf red LEDs with 1 or 1.4A current, which is a good match for these.
These LEDs also have (as I saw) the same MCPCB solder footprint, as the Osram KW CSLNM1.TG, so you could also sell them pre-soldered, with the recent 3030 MCPCBs already available.
I see the H1-A is now “on sale” (can't use coupon then), with an old photograph it doesn't abides by. Most users here prefer quality over cut corners. Cut corners may end up costing us money.
The fcbB46 is the warmest bin ranging from 5300K to 5800K but the duv is also above the BBL unfortunately according to the chromacity coordinates for this bin in the data sheet.
You can plug in the 4 corners of the tint quadrant into this link to see the CCT range for this bin.

It could still be below the BBL as we all know the actual emitter and bin labeling can be quite off sometimes.
I’m no expert but I don’t think this is right. It seems this optic sits too far down into the MCPCB since either the optic legs don’t have a big enough “shelf” and/or the MCPCB holes are slightly too big.
Sitting on the flat granite I can slightly rock the optic back and forth by the two optic legs but just barely. It’s basically just a thin sheet of paper shy of straight up resting on the MCPCB. In two of the MCPCB holes there is almost no rotational play so it probably wont shear a dome but I feel like it has a decent chance of crushing the substrate or not being in the correct focus?
MCPCB is 1.6mm high (listed as 1.5mm) so that probably doesn’t help either
Had the exact same problem, the optic rests on the dome meaning that the optic cuts into the domes when it’s installed with any pressure on the optic. Lost 4x XP-L HI’s finding this out.
