Do I have tubs? If not, question

[Xirxes23]

Are these tubs?

If not, i have some that i ordered, how do i get the best color out of them? I have 250W 15K XM over a 30 cube. High light? Shaded? thanks

I don't think those are Tubbs.
Under 15k XM, Tubbs should be much more intensely blue.
Here's a pic of mine under 14k Phoenix:

Mine actually look bluer than that in person.

I would think you would be able to get good color out of them under that bulb.
I haven't had mine long enough to give you a definitive answer, but from what I've heard from others and the little I've been able to observe in mine, they seem to prefer high light.
I have mine probably about 9 inches below a 150w 14k Phoenix fixture, and they've definitely grown several new polyps in the month or so since I took that pic.

I would say.. not Tubs.. here's what mine looked like under 14k Phoenix top down...

Could it be your camera exposure?? Here are a few of mine to compare too. The shots are brighting up a bit. Maybe to the eye a litte darker blue.
