Difference in Evolo optics This is the two different optic designs the Evolo lantern can come with. On the left is the optic seen in the Sapphire and ZX1. On the right is the optic seen in the ZX3. Each lantern has a 45W cosmo lamp, and the adjustable lampholders are set so the arc tube is in the same physical position. I do wonder how the different optics compare for performance, and what the difference in distribution would be like. Keywords: Lanterns

Well fire 'em up and find out... Wonder

I certainly could do, but I don't think it makes that much difference at 9ft height. I might light them up for the fun of it anyway Mr. Green

That would be good. Cool

I would also like to know what difference there is in photometry between the two designs. Maybe it's just one design specifically made for smaller lamps such as the CosmoWhite, and the other one is more universal and can be used with standard larger HPS and MH lamps (but happens to be fitted with a Cosmo lamp here)... You have the two lanterns, so you can do some nighttime testing to see if there are any significant differences Wink
