Hi! So i was going to replace the t5 bulbs that were under my hood and I noticed they were the old standard 28 watt t5 bulbs. The fixture is a R-zilla and 46". Do they still make 28watt t5 bulbs that size? I can't seem to find them anywhere. Amazon has them but other than that I'm not sure where else. I would rather not pay an arm and a leg for them.
