Arrived on time and fit my light fixture (I had measured beforehand). Warning: does contain mercury. There is a pick up for these light bulbs in my city so I'm good, but you might want to check.

Great Fluorescent lights, long lasting

These bulbs are excellent to replace in our existing ballasts which are of the older style compared to led lights nowadays.

I use 2 of these lights for a laundry room that's approx 10 by 6 and the the two lights light up the room quite efficiently.
