Do T12 bulbs contain mercury?
It’s true that CFL bulbs do contain a small amount of mercury, sealed within the glass tubing, and it can be released as vapor after a breakage.
Can you replace T12 with LED?
Can you actually retrofit T12 to LED without changing out the ballast? Actually, yes. But before you make a decision, there are other LED solutions to consider for a high-efficiency lighting option for existing T12s. A lot has changed in just a few years in the lighting industry.

What is the white powder in a fluorescent tube?
phosphor
The white powder that you see inside a fluorescent light bulb is called phosphor, which is a substance that emits visible light whenever it absorbs ultra violet energy waves. The phosphor used in a fluorescent light bulb is what determines both the color temperature and the color rendering index.
Can LED tube lights replace fluorescents?
Yes, you can replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you just want to replace the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes.
