Superior LED Tube Lights are designed to easily replace toxic, higher wattage fluorescent tube lights commonly used in offices, warehouses, signage and tunnels. Our Superior patented design generates the longest lamp-life on the market and our high-quality components are so energy efficient they have earned the EPA Energy Star Rating. GUARANTEED FOR 7 FULL YEARS, lab tests show they’ll operate maintenance-free for 100,000 hours. That’s over 11 years if they’re left on 24 hours a day, 7 days a week! Our latest model LED tube has such a high lumen output, we can de-lamp a 4 tube fixture with only 2 tubes and still maintain the same amount of light on the workspace. And, since they operate at an ambient temperature of 78° F, they do not turn brown or contribute to the building’s summer cooling load. These 3rd generation LED tubes are EASILY INSTALLED INTO EXISTING FIXTURES. Since the old ballasts do not need to be removed, you save expensive disposal costs. Our small external driver for is attached to the fixture with a peel-and-stick adhesive and the LED tubes within the fixture are powered in series directly to the driver with included cables. The drivers are also guaranteed for 7 years & lab tests indicate they will last 147,000 hours or 16 years of continuous use! Switching to our Superior LED tubes yields an average Return on Investment of 50-80%.
