off topic here . i am not talking about reef tanks . think when they really start using them mainstream . not the crude ones they have out now .like in recess lighting fixtures , any light fixture , comercial lighting . the difference in power consumtion is incredible , nevermind the effects . the quaity is awesome . i hate flouresent lighting in home applications it gives me a headache . it really has a long way to come . the price will really come down once it is being installed in homes on a mainstream basis . how could it not it .
