Hamilton 400w Bulbs

[hiepatitis]

I want to try the Hamilton 400w bulbs either in 14k or 20k. Anyone try these? How do they look?

if i remember right, this is what tat's tropical down south uses. the 20k is pretty deep blue -almost blue+ blue. i don't remember the ballast brand but they were magnetic.

was it too blue? strong enough for sps?

Neptune Aquatics is using the 14k and look light blue to me.

I think they're using the 250w. Can't find ratings on Sanjay's

You're right. They're using the 250w.

hey i had hamilton 14k 400w bulb mixed with a blue wave electric ballast. The 20k is a deeper blue but i liked my 14k it was nice and cheaper then the other bulbs they had there.
