Source for bulbs - Coralife quad 96W fixture

[Matt]

We have a coralife 96W "quad" fixture, which comes with a 50/50 bulb. Last time we replaced it, we bought a bulb from Bob I (not much seen in these parts lately) which was a 10K bulb (no actinic).

Anyone know where to source such a bulb locally or online? Again, I'm looking for a 96W quad bulb, 10K (not 50/50 - and not Coralife).

Cheers,
Matt
