Stay clear of the crap at Lowe's and Home Depot too. Those are the worse fluorescent fixtures on the planet and they still charge top dollar for them (highway robbery right there!). They use crappy residential grade ballasts that drive the lamps at 60% of their potential (aka "energy-saver" ballasts) and have low power factor, which means they use more current for the same amount of power draw (you don't necessarily get billed for low power factor, but it means you can't use as many fixtures on the same circuit as you can with HPF). Commercial grade fluorescent fixtures have (slightly) higher quality ballasts that drive the lamps around 88% potential (considered the norm, though I always go for high ballast factor, which drives the lamps at around 118% potential) and they are high power factor, which means less current drawn.
To be honest, they don't really make rock-solid fluorescent lighting anymore. They made solid fixtures through the 90s but the ballasts have been crappy ever since they banned PCB capacitors around 1980. Pre-1980 fluorescent fixtures were excellent. Nice and bright lamps, rock-solid fixtures, and they would last FOREVER! Modern fixtures often fail before the first lamp change, which is asinine IMO. Just make sure you don't waste your money. I know you're not much into fluorescent lighting so you might be fooled by the LED crap. But that's all it is- crap.
the average home with sprinklers is BBB+ class and I don't think you have one so yay no
I have several 1940s-1960s F40T12 preheat and rapid start magnetically ballasted fixtures and they far outperform any modern fixture. Sure, they use a little more energy but at the benefit of better reliability. Those lights will probably outlive me and I'm 17 and they're already my parents' ages and some of my fixtures are my grandparents' ages! LEDs will not last you 25 years. That's a flat-out lie and the manufacturers all know it is. It's just a gimmick to justify the higher cost (aka higher profit margin) of LEDs. It's all a big consumerism game.
Mike: 100% RIGHT! LED is a lie oh,Did you know the providence place mall is a class BB- that is like 65 on a report card Only 1% of it can be ON at a time ! or massive presser drop
