V22 Perfect Beam TST

V22 LED Series offers the latest TST LED technology. What is TST Technology? TST Technology came up with an innovative LED bulb design where the the chip is soldered directly onto the bulb body, thus reducing the need for a copper plate between the chip and the lamp body. This design greatly improves the thermal conductivity and heat dissipation performance of the LED headlights. The sunken PCB technology makes the perfect beam pattern and the bulb shadow is the thinnest it has ever been.
