Anyone still using par 38 bulbs?

[Fishy!]

Well I picked up a halo par 38 from a local reefer today. Set it up on the tank and wow! Talk about shimmer! I will defineately have to keep the tank topped off to avoid havin a seisure lol. I find it quite blue but I'm sure it's just that I'm not used to it. I snapped a before and after.

It's actually not quite as blue as it shows on my iPhone but a drastic change none the less.
I have to say it doesn't seem as bright even as the single 8w t5 that came in the stock hood, but I'm guessing that's cause it's more concentrated? Less light spillage?
Will leave it on for a while and see how it goes. I will report back.
