What do you need the 400 watt MH for? If it's for growing FW plants, I have some lower kelvin ones that you are welcome to, (between 3700 K and 4100 K... same ones you see being used at Home Depot for lighting). They are Base up only, so, you can only use them in pendants. I'm currently using one on my 33 gallon salt, and my blue acro is growing like a weed, (go figure
), along with my two colt corals, and some mushrooms, (sure blows that whole kelvin thing out the window, eh?). Let me know.
