Litetronics Neolite NL-15427 T2 lamps are the next revolution in CFL miniaturization; the reduced tube size gives Neolite lamps a smaller maximum overall length (M.O.L.), allowing them to fit into more applications. Neolite lamps have extraordinarily low energy use, yet yield up to 75% savings in energy costs. Neolite lamps contain only 1 milligram of mercury inside its tube, a 75% reduction from the industry standard of 3-4 mg of mercury, making Neolite safer for the environment when it is disposed at the end of life. Neolite lamps have a 10,000 hour life - ten times that of standard incandescents.
