Shat-R-Shield offers plastic-coated, shatter-resistant / shatterproof compact fluorescent (CFL) lamps. A versatile, high-efficiency replacement for incandescent lamps, Shat-R-Shield CFLs offer superior performance with longer life, lower wattages - lower utility costs, fewer relamping cycles and safety from the risks of broken glass. If a Shat-R-Shield fluorescent lamp is accidentally broken, virtually all glass, phosphors and mercury are safely contained within the clear and tough, skin-tight plastic coating.
