Energy saving and environment friendly
To conveniently replace the traditional T8 fluorescent tubes with excellent features, like longer lifetime (>20,000 hrs min.), higher luminous efficacy, lower power consumption, lower heat radiation, and lower environmental pollution, GlacialTech proudly launches the unique Lower Power T8 Series LED Tubes, designed to use efficient 4, 8, 16, and 20W LEDs respectively, corresponding to common 1-foot, 2-foot, 4-foot, and 5-foot tubes, and individually supported by four AC input voltage specs, including 100-110V, 120V, 220-240V, and 277V. They fit standard G13 sockets and are an optimum lighting solution for commercial, local, or public area lighting.
If the input voltage does not stay within its specified range, however, the tube may not light up due to a low input voltage insufficient to start up the tube successfully. Or, the tube may flicker on and off due to a high input voltage, setting off the inbuilt Over Temperature Protection (OTP), which shuts down the tube at overly high temperatures as well as automatically starting up the tube at a relatively low temperature.
It should be highlighted that the patented LED driver built into the LED tube is one of our eco-friendly inventions. Unlike the conventional LED drivers, emitting Electromagnetic Interference (EMI, also called Radio Frequency Interference or RFI) via either electromagnetic conduction or electromagnetic radiation, our innovative LED driver emits neither noise nor interference and will not interfere with the effective performance of noise-sensitive electronic devices such as television sets, cell phones, AM/FM radios, medical instruments, military equipment, and the like.
