nope they don't. a DE actually puts out less light over the same area but because of the size they can have reflectors that are designed to concentrate the light over a smaller area giving the appearance of more light.

If you are stuck for room they are the ones to use. but you can buy the HQI ballasts and drive the screw in ones also as I do. this way if you go 250 watt you can run any screw in bulb out there that is 250 watt on a HQI ballast.
