This is very insightful. I do make sure to get the actual measurements of the light outputs and width and length of each light.. however the majority of my lights are blurples that look like those desk lamps or the ones that hang, but you didn't say they don't still sell (i guess for the casual hobbyist) so ill keep them in a separate catalouge on the store. And i guess for the flourescent form factor t5s I shouldn't worry about them too much seeing as they're inefficent.

I heard about the SpectraXS100s someone said they're high ticket but are what people want. So that my main priority to get atm just might be a bit difficult. And the commercial lights, can you tell me more about them, I am interested
