Kihung T8 LED Light Tube 4ft 22W (75W Equivalent) 2300Lm Ultrahigh Brightness 4500K Daylight Glow, Frosted PC Cover & Aviation Aluminum, Pack of 1

These lamps from Kihung are designed to fit light fixtures that use 4’ long T-8 lamps. The most common application for a product like this is for retrofitting an existing fluorescent fixture and converting it so that it can use LED lamps. Unlike a fluorescent tube, these lamps are not cylindrical in shape. A strip of LED’s are mounted inside the tube, which is plastic, and has a frosted area that helps to diffuse and soften the light. The lamp consumes about 22 watts, and supposedly produces 2300 lumens, with a color temperature of 4500 degrees K. Like most other LED products, the cost for this type of lamp has decreased significantly in the last few years, and the current cost is very competitive. As expected payback times have decreased, retrofitting fluorescent fixtures has become a more practical option. These lamps are produced in China. This is not unusual, as many LED products sold in America use LED’s, drivers, or other parts that are from China. I received a pair of these lamps for evaluation, and was generally pleased with the light output, and the color of the light. Since the lamp has a diffuser, it would be most suitable for use it a fixture without a lens or diffuser, like a strip light. The product was securely shipped in a box, with a cardboard tube around each tube for additional protection, and plastic inserts on the pins to help prevent damage. There are some LED tubes that can replace fluorescent lamps without having to rewire the light fixture. That is not the case for these lamps, as the wiring in the light fixture will need to be modified to bypass the ballast, to use these lamps. An electrician does not necessarily have to perform this work, however some basic knowledge of electricity would definitely be helpful. If you question your ability to rewire a fixture correctly, consult a professional, or someone with the required skills, as you would definitely want to avoid a short circuit or other mishap.
