Reflectors for Osram GD+?

[AndyF]

Does anyone have any experience on the following:

Fraen FGR-N1-DP1-OR, 27 mm narrow beam reflector.
Fraen FDP series lens/holder, either FDP-N1-GDP-OR (narrow beam) or M1 (medium beam).
Ledil Tina series.

I am doing research for a possible build. Thanks in advance.
