For commercial growers, LED lights might cut the electric bill in half when ac is figured in. Still takes years to cover the cost.My vote. Is veg with LEDs. And finish with HPS. If you're going to invest in a 2000 dollar LED array buy the best one you can get.
My friends who switched over from HPS to expensive LED arrays were not pleased. They say the investment won't break even. And they didn't gain quality or weight. Home scale growers seem pretty pleased with their LED lights generally. So consider why you want one. I mean no bulbs to recycle. Thats a plus. But so far LEDs haven't performed any miracles.
