I've got 250w double ended ones laying around but not 150w. I generally try new bulb brands every year, but loved these bulbs so much, that I gave up on trying anything else. I'm getting ready to order a new set this summer so that makes 3 years in a row that I've gone with these.

They've got a nice blue tint, but still enough white to appear very bright. You won't be disappointed in them.
