    Our guide to finding the right LED tube, every time

    What to do when your fluorescent tube burns out? Whether in your home or business, you can replace those old fluorescent tubes with energy-efficient, long-lasting LED tubes. Philips offers several options for homeowners and professionals alike to choose from.


    Why upgrade from fluorescent to LED?


    LED linear bulbs don’t contain mercury and are great for locations where the lights are frequently turned on and off. Switching the lights on and off can prematurely burn out a fluorescent tube. LED tubes also offer greater energy efficiency and a longer lifespan when compared to fluorescent. And, Philips LED tubes are designed to meet EyeComfort requirements* by providing comfortable light with no visible flicker or strobe. LED tubes are available in a range of color temperatures so you can match the light of your existing fixtures. And some LED tubes, like the Philips MainsFit, allow a ballast bypass installation that eliminates future ballast maintenance.


    So how do you choose the right one? Philips offers 3 families of LED tubes based on ballast compatibility and how they are installed. There is a tube for every application, making it easy for you to choose and install with confidence.
