USALED has released its T10LB4 LED light bar, a retrofit solution for fluorescent tube lighting fixtures. Installation is simplified with magnetic mounting clips and a quick-connect line voltage wire, eliminating fluorescent ballasts and T8 lamp holders. The durable construction translates to a 50,000-hour design life, which means maintenance-free operation for 11.2 years when operated at 12 hours per day. The LED light bars are ideal replacements for T8, T12 and T5HO fluorescent lamps in 16-, 18- and 28-watt versions. When a light bar fails, replacement is easy: Unclick the quick disconnect, remove the light bar and attach a new one.
