The Firefly LED Greenlite is available in warm white (3000k) and daylight (6500k) making it suitable for almost any standard domestic application. This 6w lamp is available in B22 and E27 bases and will comfortably replace a 60w incandescent or 15w CFL lamp. The white plastic diffuser is not only aesthetically pleasing but also gives the lamp a 180 degree beam angle. This lamp is rated at half the wattage of an energy saver (CFL) with a longer lifespan at 10 000hrs versus 6000hrs for a CFL and retails at the same price point. More importantly it is also mercury free while a standard CFL contains 5mg of mercury.
