Aquarium Advice Addict
Having been in the electrical industry for 30+ years, I have learned a bit about lighting (although aquarium lighting is a different story). When a manufacturer is making a commodity fixture and price is key, they paint gloss white, when it is a specification grade fixture and high dollar it is always a mirrored finish reflector. Because the T5HO is relatively new and because of the area they are trying to cover, all of the manufacturers have gone to the mirrored reflector even on the commodity fixtures. Tells me that gives them the most punch for the buck.
