LED troffer light retrofit kits and bulbs are a great solution for upgrading your current fluorescent fixtures without a lot of work. Whether you need dual-ended or single-ended, ballast-bypass or plug and play, 2-foot or 4-foot, there's an LED T8 tube for any fixture. These mercury-free bulbs turn on instantly and won't flicker like fluorescent T8 tubes. T5 tubes are also available and have the same benefits. Other easy-to-install solutions are magnetic strip retrofit kits. These kits mount in place of traditional tubes. They speed up the retrofitting and decision-making process especially on larger commercial jobs—no more worries about what kind of tube to use, replacing tombstones, etc.
