Yeah, fair enough. It's probably closer than I thought.
If you live in Cali and pay closer to .30 or .35 per kwh, then it seems like LEDs might be the way to go, especially when you factor in the cost of the additional AC to make up for extra heat of the HIDs.
I'm paying .17 per kwh, but then again, I didn't plunk down $900 for my LEDs. I wanted to try them out a year or so ago and got 4 Mars 300s for less than 300 total. In a 4x4 tent, it's almost too much light and slaughters my 600 watt HID fixture in terms of production, but draws about 560 from the wall total. I highly doubt they will last 30,000 hours, but it was a cheap way to get mt feet wet, so to speak.
My next LED adventure will be building some DIY Cree COB units, which I am going to build into stripped down 4' fluorescent fixtures. I mentioned this project (under my YouTube name) to GrowMau5, but he said he's too busy to do it. If I ever get around to building them, i think the fluorescent fixtures
I've
