So I'm hunting around on Ebay and I come across a 150 Watt HPS Digital Ballast. I know digital is the "way" to go as it's more efficient, cooler temps and the bulbs produce more lumens.
Question is, for such a low power bulb, would it really make that much difference over your standard back yard mechanic ballast?
