halide bulbs

[anubix00]

is there a difference in the halide bulbs that screw in as compared to the ones that are double sided? is one any better than the other?

Most say the double ended are better. More exspensive too. A 150W is compared to a 250W single ended in briteness.
You can pretty much get all the colors in both.
