take that guide with a grain of salt, while everything they sugest will work it is not always the best set up. where this becomes aparent is in the 250 watt bulb catagory, if you look through it all DE 250 watt bulbs are M80(HQI) and all SE 250 watt bulbs are M58(pulse) they even list this for the german bulbs such as AB. it is weird that they have only they radium 250 as either.

from lighting tests and manufacture data if ytou are going to use a 250 bulb, no mater what kind it is use a HQI ballast. it will give you longer bulb life and higher output because it is running the bulb properly.
