UL Issues Warning on Replacement LED Luminaires

8/1/2019

UL is warning facility managers and installers that installing double-ended direct replacement LED lamps in energized luminaires powered by magnetic 40 watt ballasts might pose a shock hazard. Recent UL testing confirms that luminaires with magnetic ballasts intended for F40T12 fluorescent lamps might pose a risk of electric shock during installation of LED lamps intended for direct substitution of a fluorescent lamp while the circuit is energized. Magnetic ballasts intended for F40T12 fluorescent lamps have not been available in the marketplace for many years. But given their prior widespread use, these magnetic ballasts may still be in service in some older installations. Click here for more information.
