Sunlite LED T8 plug and play produces a super bright light while saving energy. This lamp can be used as a simple swap of a fluorescent lamp with a medium bi-pin (G13) base. It operates directly with the existing fluorescent ballast, thus eliminating the need for ballast removal and rewiring. Producing a soft white light, this lamp is ideal for use in a wide range of applications, including commercial, residential, retail, healthcare, hospitality and schools. This lamp draws only 15 watts and delivers a super bright 2100 lumen light. It has a low estimated energy cost of $1.81 per year and has an astonishing 50, 000 hour lamp life (which will last over 45 years based on 3 hour per day use), making it virtually maintenance free. It is UL listed for damp locations and DLC approved. It contains no mercury elements and does not release any hazardous gasses so there is no need to worry in case of breakage and no need for any special recycling as with fluorescents. Please refer to the installation guide for a list of compatible ballasts.
