The difference between a 1X4 LED troffer and a 1X4 LED fluorescent fixture has to do with the type of light they are. Yes, they are the same size, but LED lights are much more useful and beneficial for you in the long run. Both lights are better when comparing to incandescent bulbs, but LEDs are the best type of bulb you can get. Though the initial cost is more for an LED light bulb, it has a much longer life span and is more cost efficient. The typical lifetimes of LED bulbs are quoted to be 25,000 to 100,000 hours. Another advantage to LED bulbs is that they don't contain any mercury. So not only are these bulbs non-poisonous, but they produce brighter light using less energy so they last longer and require less maintenance. Overall, LED 1X4 Troffers are always going to be better than fluorescents. Read more about the LED Lighting on our blog!
