Other Options for T5 31W bulbs?

[cerulean_blue]

I have a Coralife T5HO 4x31w fixture over my 29gal SW aquarium. I will need to be replacing the bulbs soon. Are there any options for bulbs that fit this size fixture other than Coralife? I measured and it seems like the bulbs are around 27.75"?

I have 2 of these light fixtures. You are tied to Coralife for bulbs. No one else makes the 31 watt bulbs but them. I've checked everywhere including lighting warehouses.
