Product information

Pack Of 25 - F36W/840 fluorescent T8 tube light bulbs ft Triphosphor - 4000K Cool White Tube length: 4ft - 1200mm (1212mm with pins) These triphosphor fluorescent T8 tubes provide a superior quality of light, with greater energy efficiency and a longer life. Unlike a standard tube, triphosphor tubes retain their high quality of output throughout their lifetime. With uniformly good colour rendering illuminating objects in their natural light, these fluorescent tubes are ideal for shop lighting, as well as for high-quality lighting in offices, schools, garages and warehouses. Rated lifetime of 15,000 hours (That's around 10 years of light, based on average use of 4 hours per day). Fitted with a standard sized G13 2-pin (13mm apart) caps to both ends. NB - This replaces the older, less efficient Halophosphate tube. For maximum performance and efficiency from your new fluorescent tube, we recommend you replace the fluorescent starter at the same time.
