So after explaining to my wife that I usually spend about $1000 on lights, then have to have the fans for cooling, having to take them off the tank for maintenance ( just another excuse ), the heat that comes out of them between the electric bill and if the bulbs accidentally got wet, having to change and buy more bulbs, and a few more BS small excuses...if these lights are really good, I got the ok from the "boss" to get them after we move! LOL, I LOVE my wife. Any how, what I don't know is if they are good, how exactly they work, or basically anything else besides that they are expensive, can lift up off the tank with the mounts, and have little to no heat! Help with info would be great, as I know there are many knowledgeable people on here!
