*Each box has 25 pieces - the products are priced per box - $3.99 ea.* The 4ft LED Tube is a direct replacement for traditional fluorescent tubes. These LED Tube Lights consume only 18 watts of electricity which saves up to 70% energy compared to fluorescent tube lights and provide superior lighting, and run over 50,000 hours. Each T8 glass tube provides more lumens per watt than other tubes which saves you both cost and energy. The LED T8 Glass Tube features a versatile design - Single/Two End Bypass - that allows quick plug-and-play installation. LED tubes with Ballast Bypass are compatible with existing fluorescent fixtures, making retrofitting simple and cost-effective. By bypassing the ballast, you eliminate the need for ballast maintenance or replacement, further reducing maintenance costs over time. Our 4ft LED tubes provide instant illumination without any warm-up time, unlike fluorescent tubes that may flicker or take a few moments to reach full brightness. This instant-on feature enhances convenience and productivity in various applications. LED technology is more environmentally friendly than fluorescent lighting. LED tubes contain no mercury or other hazardous materials, and do not emit UV or IR Radiation which makes them safe to use. We maintain the highest standards - UL DLC 5.1 Premium - for our 4ft LED Tube Lights and other products by rigorously testing each one to ensure optimal performance and safety. It also has a 5 Year warranty. NOTE: You must bypass the ballast. Existing ballast can not be wired for this tube to work.
