Except for the LED lenses themselves.. I don't think they have optics in the sense you are thinking about..I've been searching for information on the optics used on Finnex LED's. Does anyone know which optics are used on each of the lengths? Has anyone changed out the optics? I have asked for this information in several threads with no response and even emailed finnex themselves and their response was "We do not the information. The manufacture did not provide us with these kind of information. Sorry"
I am in the market to buy 3 fixtures in the very near future and finnex isn't doing a good job at selling me on their product.
Any help will be much appreciated!
They just run "native" spread.. AFAICT..
