 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.
