Saving power more than 80%,And high lightingς with led T5-t8 2. Adopt the transparent PC as the Tube, Protect the environment, Be recyclable, Adjusting the illumination so that energy saving and achieve adjust the cavity ring-down spectroscopy. 3. 3.5 years long life, Special mix design of LED perspective. Start earily,No flash,No noises. 4. High-frequency constant current source (85%), and with the protection device of temperature to achieve working normally when the voltage in imbalance. Special circuit design, to avoid the single LED to be damaged then to affect the whole tube lighting bad. 5. No flash,No pollution, No interference.
