Get powerful illumination for low energy costs with our Simply Conserve 4 ft. Linear T8 LED Tube Light Bulb. This energy-saving LED bulb is ideal for enclosed indoor fixtures. You get a 14-Watt LED light bulb with the equivalent output of a 32-Watt traditional fluorescent light bulb. That's significant energy cost savings for reliable lighting that lasts for 50,000 hours of continuous use. You get the same 1800 Lumen output of a comparable fluorescent tube but free of the yellowing and bending that comes with older T8 bulbs. Hybrid technology makes it compatible with either Type A or Type B installation. The 4 ft. LED bulb can plug and play into an existing compatible ballast for your convenience. On the other hand, you could bypass the ballast and do a direct-wire installation in either single or double-end configurations. Either way, you get an easy setup for durable illumination that lasts for years. Our energy-efficient 5000K LED bulb comes in a full glass housing that allows the unit to run cool with minimal heat output. It's mercury-free for peace of mind, springs to life in less than a second, and it's flicker-free so you will always have steady reliable lighting. Our LED replacement for fluorescent tubes is well-suited to offices, conference rooms, hotels, academic complexes, and commercial and medical facilities. It's RoHS compliant and cULus listed and it comes with a limited 5-year warranty.
