Timer for metal halide
Can anyone provide guidance on how large a timer I need for a 400W
metal halide grow lamp? The vendor suggested a 15 amp grounded outlet, the stated he likes 20 amps ones. However, I recently ran across some nice, grounded 10 amp, outdoor timers ( Intermatic . On the side they list capcaity as 1200 amps R Resistive or 1200 amps Tungsten. I know that Metal halides are different, but do I really need a 15 amp timer or will these 10 amp ones work? Thanks Mike |

Thanks Mike I use the cheap ungrounded ones; they last a year or two before the contacts burn out -- just like the expensive heavy duty grounded ones. I haven't tried the electronic timers, like what I have a bunch of fluorescents plugged into, but they should work too. Bob |
