what LED to use in a C8+ convoy?

The Anekims I have use those CSI.NY emitters, ’though forgot which ones specifically.

Ah, found it:

Speaking of the emitter, it’s a Osram CSLNM1.F1 green LED, with 1sqmm die, and phosphor-converted green (a blue emitter with green-emitting phosphor layer on top). A small emitter in a large reflector means lots of throw.

That’s the green, and it’s similar for the white version.

Those li’l beasties throw like Hell…
