Looking for electricians knowledge on 4’ Florissant bulbs

All I can add is that if you see cheap LED replacements, LOOK at the claimed lumens before buying.
Some don't even claim to have the same output as a typical T8.
I noticed that when looking in the box stores and ended up just buying some T8s.
Also if you are sensitive to glare and contrast, sometimes the LEDs - depending on how they are placed - are worse in that respect than flourescents.
