Conrad also have an even more floody optic, 10624, in stock too. Which one to get? 
Both 
Left to right: original D4 clear 10622; frosted 10623 25.9 degree; 10624 40.3 degree (legs unclipped at this point — 2 legs need to be removed because of the screws in the MCPCB)
My standard D4 Nichia had a bit of a brown spot when used close up (i.e. on ceiling), but floody optic does away with that
