4 ft T5 bulb trade

I have some 8-new (1-2 months use) 5600K T5s, that's about right for hydroponics/freshwater planted tank/live fuge w/ algae, etc.
Looking for Reef lights, especially the blue/purple/actinic, but also up for some 10k or higher, age is not important. If you have a 12-8 month old bulb you're going to throw away, please send it my way.

Very happy to trade mine for yours. Hoping to get at least 3-4 of these traded out for blue/purple/actinic, everything after that is gravy
