Why are these HPS lights so cheap!?!?

The conv. bulb is hps that runs in a mh ballast. cost is around 70.00

Keep in mind any kind of brandname HPS bulb labeled specifically as a grow light is going to cost more then a plain no brand hps.

what about plain old metal halide bulbs do they work just as well also

mh works well in veg.

The issue here on the Metal Halide, is that I only have 4000k bulbs... They are useless for what our common goal is. It just seems that the HPS's are my best bet..

I got a 150w HPS ballast kit, socket, and bulb for just over $50 on 1000bulbs.com I live with in driving distance from one of there warehouses so I didnt even pay shipping. I love that place

Well I ordered two of the 2100k HPS bulbs. The price was just under $30. So we'll see.
