I'm surprised there's been so little discussion of replacing fluorescent T8s with LED equivalents. Savings are significant, but don't get the kind that brag you don't have to remove the ballasts -- those actually require the ballast, so when it fails, you're in for big bucks, and you have to feed them (they love electricity) while they're working. I've replaced over 50 of these in my houses and others', and aside from the hassle of taking the fixture apart, it was a real joy to toss the ugly old ballasts into my hazmat bin. I've been using Hyperikon bulbs (from Amazon); they come in different colors, they've been reliable, customer service from the manufacturer (when 2 did fail) was super, and they're only $10-11 when you buy in 24-packs. Costco also now sells a nifty shop-light kit for not much money with the fixture, line cord, and hanging hooks, and they're chainable. A neighbor here replaced all the fluorescents in his shop with super-white LEDs and the difference is stunning.
