I was looking at this web page and saw something I've never heard of it's called a warm MH bulb it claims that its temp is 3000K what is the temp of a MH to HPS conversion bulb? This bulb is also 70 dollars cheaper so which one would be better to use?

A "warm" lamp is a MH lamp that refers to a "redder" burning lamp. A standard lamp usually runs around 4000K, a "warm" lamp will range anywhere between 3200K and 2800K. Your conv. lamp usually will run at the 4000K, unless stated. There are "cool" and "warmer" conversion lamp, "cool" lamps are lamps that burn above 4000K, usually 5200K to 7200K. FYI, a standard HPS lamp runs near 2000K.
