LED lights are ideal for refrigeration purposes, as opposed to fluorescent tubes, the light output and color temperature of the LEDs are not compensated due to lower temperatures. LED technology actually increases light output and lifetime in colder environments and can save significant energy costs over high watt fluorescent lighting. LED Smart manufactures direct fluorescent replacement lamps for use in applications such as coolers and vending machines. Our light tubes are compatible with virtually every standard, ballast equipped fluorescent light fixture, without any need for modification. This product works as a high voltage replacement (120V – 220V) or low voltage equivalent with an external power supply that replaces any existing ballast. LED Smart light tubes come in 3 white light temperatures including warm (2800K), neutral (3500K or 4100K) and cool (5000K) and offer a 3 year limited warranty.
