Cree Recalls LED T8 Lamps Due to Burn Hazard
The recent recall of Cree Lighting’s overheating LED retrofit tubes (listed this week on the Consumer Product Safety Commission website) could likely have been avoided if the LED manufacturer had employed a hardwired retrofit solution for standard 2X2 and 2X4 fluorescent retrofit applications. In an effort to assist endusers affected by this enormous recall, Deco Lighting has chosen to offer discounts on its Linea retrofit kits to endusers who have purchased any of the “quick-fix” LED lamp products designed to fit into existing fluorescent sockets and use existing fluorescent ballasts.
“The fact that the LED tube overheats is not a surprise to us at Deco Lighting,” says DecoLighting President Ben Pouladian. “In our opinion, only a hard-wired solution can safely retrofit a fluorescent fixture to LED.”
The problem with using an LED tube is that most of the original fixtures used T12 lampsand magnetic ballasts (an analog system), but were retrofitted to T8 using an upgraded electronic ballast. If the retrofitter did not upgrade or replace the existing T8 tombstones then a small amount of leakage current is emitted. T8 lamps can tolerate this leakage. Yet, with solid state LED lamps, this current affects the LEDs and the power supply, causing the sockets to overheat and melt. Deco Lighting does not use the tube technology for this very reason… Click here to view the full article on EdisonReport.
