Are there any major drawbacks to having a 4ft light with one 400w HM bulb instead of two 250w ( other than the loss of 100w of light )??? The bulb is in the center of the fixture with PC's around it. The light will hang above my tank several inches, will it concentrate too much light in one place? The reason I am asking is this light is almost $100 cheaper than the one with 2-250w.
