i am aware of the principle (into photography). but a flat white surface isnt the same as a highly polished, mirror finished, piece of aluminum.
somehere here, or nano-reef, posted pictures of his new finnex. the reflection was so clear that many posters were fooled into thinking that the 2 bulb was a four bulb unit.
even trying to correct the owner that he counted wrong lol. it stands to reaqson, that if a duplicate image is being produced by a reflection, that the reflector is redirecting a high percentage of the light.
id just like to know how much of it, and how much compared to the others. enough to offset the cost?
especially at your par readings. already out shining (pardon the pun) halides, even if there is a loss, a less expesive fixture may be worth its weight in photosynthetic gold.
