Exactly so.
Most growers agree, the point where HID becomes more efficient than CFL or T-5 is somewhere above 200 watts.
IE, unless you're getting more than a 150 watt HPS, the CFL's are going to be just as efficient.
psteve Reviewed by psteve on . HPS in a regular lamp? Does a hps bulb require a special fixture i know ive read alot about these ballast for the real high wattages but for a 50 watt or so hps bulb does it need any kind of special fixture or can any fixture that can handle that wattage support a HPS bulb, Thanks in advance.
