I have 2x 8-foot linear shop lights in my standard 2-car garage. I like bright light, so I have been using Philips Alto 32-watt 6500K 48" fluorescent tubes.

Instead of using the existing ballast wiring, I bought solid core 14AWG wire, which fit perfectly into the new lampholder wire sockets.

Literally, one 5000K bulb was producing more, and brighter, light than my other fixture of 4 fluorescent bulbs. These bulbs are rated for 2180 lumens each, but produce more light than the fluorescents' rated 2850 lumens. Needless to say, I am extremely pleased and will be purchasing more. They are a bit pricey, but if they last as long as the other LED bulbs I currently use in my house, they will be well worth the investment. My only disappointment is that they are only sold online.
