Photo cell- max current

[spark master]

what is the highest current rated photo cell on the market ?
I have 3) 400W HPS wall packs, and 2) LPS lot lights on 1 circuit. Need to go on 1 photocell. (the rotary timer is coming out)

Is this boarderline for a lighting contactor ?

"Watt" voltage? (pun intended ) ...and "watt" wattage on lot lights? Ballasts' rated current?

Is this boarderline for a lighting contactor ?

Can't say without the additional information.

all 120Volts. 400W HPS. The LPS can't be much, maybe 100Watts each.
figure 1400-1500 watts total.
it's on a 20 amp breaker now.

The Intermatic K4141C is ballast rated for 3000 VA and 25 amps.

I would suggest puttting the lights on a contactor and running the contactor off the photo cell.

Thank you. That should do it. I was worried about the ballast inrush destroying any photocell, but this one seems speced out pretty well.
