The LED lamp, developed by Firefly LED (USA), can significantly reduce the cost of electricity. According to the creators of the device, the lamp can safely last for 40 years, without the need for a replacement.

A special feature of such lamps is the use of a large radiator surrounded by a light source. A radiator is necessary in order to remove heat from the lamp. Thus, it is possible to significantly extend the lifetime of the lighting device.

The cost of the Firefly lamp starts at about $ 35 (Starfly PAR20 model), which is a serious investment for such a device. But if you believe the official specifications, the product can pay off in just a few months and will achieve significant energy savings of 40 years.
