I’m just curious to what most people do with old t5 bulbs. We try to be environmentally conscious and I took them too a battery and bulb place where they charge $1.50/bulb. I don’t think I’ve seen any free places around.
I had them sitting upstairs in a closet for a few years now lol. I only had a few so I didn't mind paying the disposal fee. I think Home Depot does a "hazardous" waste day when you can bring paint and oil to dispose of so I'd imagine they'd take T5s too.
