Are you talking about this light? https://www.amazon.com/OPPSK-9LED-UV-Supplies-Blacklight/dp/B01HCSEFEY

If so, I actually tried this one before and it had minimal effect in my room, I’m looking for T8 bulbs specifically.

I already have this: https://www.amazon.com/dp/B01HCSEFEY

Would something like this work to sterilize? I'm guessing not.

This one seems like a good choice all the reviews are good one review specifically said 2 lights was plenty for a 40'x20' room.
