Comments This is a great bulb! Well, if you need a blue bulb.
Hamilton Tech just started carrying them so I picked one up.
I'm building a new octopus exhibit just around this one bulb.

Liked about it Represents natural lighting 1 hour before sunset or around 250 ft depth.
Two spotted octopus think it is night time and become much more active than if you were to use a 10k or 14k vho.

Didn't like All colors are lost but still shines some light on the subject!
