I have access to a 35 watt hps light. It is a small box with a light on the bottom of it. I assume the ballast and ignitor are located inside this small box. My question, how much will it take to run this as far as my electric company is concerned? I have read the forums and found the formula 35 watts x 24 hours/1000 x .10. My question is, since its a box, does the ballast and ignitor take up power too? How much electricity will the box consume as a whole? Any response is appreciated, thank you guyz.
