I think he meant 250 watts, must be the drugs
anyways the biggest difference between the two is that a DE is a HQI bulb so you need a HQI ballast. the DE bulb needs more initial voltage to create the arc. a SE bulb can be both regular and HQI and seam to work off regular ballast. but it you have a HQI SE it will run much better off a HQI ballast.
