Are the fans on the 600w supposed to spin at all times? Mine don't but will randomly on restart

The fans in the light I bought runs all of the time,sounds like a bad light.

How many needed in a 4x8?

Depends on how you’re growing it. Billy Bob is right 8 lights would only be 1920 watts at the wall. You would have an even par from poll to poll and have high par readings then rated. Be careful! Running x8 240 watt lights will get hot. You’ll need supplemental AC of at least 5k btu. And if your VPD isn’t in check you’ll crash n burn. 4 light would probably be the limit without AC. High VPD can only take you so far. Recommendation 4 to 8 lights depending on how you grow.

How much a month to run

So you have to do the math. But to help with that, running a 60 watts bulb is $17 a year at 24 hours a day, 7 days a week. If you're paying 12 cents per kilowatt hour. It's 28.3 cents per watt running for a year. Multiply that by the wattage of the lamp you choose for the years cost. Decide by 12 for a month. This is all easy information to find out, if you get off you butt, and do a fifteen second Google search.
