yeah i know! i found out about plasma lighting by accident on youtube i was looking through some guys videos that switched from a 100w diy led to a plasma light. he switched because his fan failed and the led overheated.
so i found some info about plasma lighting and its pretty interesting it could be the new alternitive to metal halide. and ive read that with the new ballasts they are comming out with for these you can adjust the color from white to blue to your liking. there is a bunch of info out there about these but heres a simple page you give you an idea about plasma lighing and how it may be used in reef aquaria
