Review on 💡 Sylvania QTP2X32T8 UNV ISN SC B Fluorescent Tube by Jaymai Alford

I bought eight of these to replace the T-12 units on all of our four foot T-12 fluorescent lights to save energy and money. Very easy to change and works great. All fixtures now work with 4ft T-8 bulbs. Now they turn on instantly, without heating and very quietly. The T-12 has always had a "humming noise" while the T-8 is very quiet. That alone was worth the cost and time to replace. It's supposed to use less power, but it's difficult to measure in a private home without some kind of pressure gauge, which I don't have. But very happy with this purchase.
