This shot was to check the height of a 10x10mm Carlco + square XPE (Cree) compared to triple Khatod lens ontop round XPE.
Think the longer legs on the Khatod need filling a little, but the 2x3mm alu (yes - those chunks of aluminium under the emitter/lens combo in the left are 3mm thick) is just about perfect, or will be when they get a little glue between them.
These things are tiny!
A sheet of single XPE emitters, with one 16 degree Carlco lens. Then some triples with 18 degree lenses.
The triples fit really nicely, the lenses slotting into the MCPCB. Ideally the singles should have come supplied on square boards so the tiny square lens did the same. It would be nice to get them exchanged but one could make do with rounds with care.
