any major difference between DE and SE?

[TrojanScott]

Besides the obvious? SE seems to be the easier choice, but when I see the DE costing more, I wonder why?

anyone? I'm getting ready to buy MH's, and want to know if SE is the way to go. What would be advantages or disadvantages of either bulb?

I find SE more practical and they usually cost less
