aaquarium ligting

I seem to always have vid issues, prolly this ipad….anyone else getting the vid?

I'm going to show my age. GE, Sylvania, Phillips. These were the big players in reef lighting circa 1980s,in the US. I would go through a very thick book call Grainger, and it would have most of your lighting and fluorescent, very high output, high output, vapor bulbs, metal halide bulbs...
