In my 3 car garage/shop I have 5 fluorescent 2-tube lights. Since I have been working at replacing most of our interior light bulbs with LED bulbs to save electricity and keep the house cooler, I decided to try out a new LED shop light in my shop. So I picked up a LED shop light that has 2 LED light bars that put out 5000k cool light. The cost was $32 from Sam's Club. I put the light over my primary workbench the new light really blew me away. The LED light is so much brighter than my 2 tube fluorescent lights. So I plan on replacing the other 4 fluorescent lights over the next month. In the picture you can see how much brighter the LED light is than the other fluorescent light.
