Re: Has it been decided as to which optic for the 5W?
Here's my 2 cents:
The NX05 works okay if a piece of scotch tape is placed over it, which removes the grids and somewhat removes the dark hole. The 30mm optics still have a bit of a dark hole in the middle, which drives me batty. When I measure the lux from the NX05, and the 30mm optics, using the same emitter, I get a reading two or three times higher than with the NX05.
Right now I'm working on getting the light be smooth. The problem seems to be the much larger light emitting point of light, which is 4 times the size of the 1W.
Don't get me wrong, the light put out is great from the 5W 30mm optics, but not as tight a beam as with the 1W lambertian.
