Sunlite LED T8 dual end bypass produces a super bright light while saving energy. This lamp can be used in your existing fixture and will bypass the original fluorescent ballast, thus eliminating the need for ballast maintenance. Ballast removal is required, as well as rewiring so the electricity is wired directly to the fixture. The dual end bypass achieves that only one side of the lamp is energized, while the non-energized pin is only used to hold that end of the bulb in the socket. This makes installation 100% safe from accidental electric shock. Producing a warm white light, this lamp is ideal for use in a wide range of applications, including commercial, residential, retail, healthcare, hospitality and schools. This medium bi-pin (G13) lamp draws only 12 watts and delivers a super bright 1400 lumen light and a warm white color temperature of 3000K. It has a low estimated energy cost of $1.45 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.
