I need to order a new 400W MH bulb. I was looking at Hamilton lighting and they have a German made 20K bulb for $70, or a radium for $90. I was wondering if anybody ever tried the cheaper bulb, or if anybody has any other recommendations. I have a AB 10K bulb right now and have been pleased w/ the look. The tank is being used for a clam tank.
TIA
