The quality of LED street lamp relies much on the heat problem. Our company uses LHP as a heaksink method that will reduce the energy lose from heat effectively. It will also increase the lifetime of the LED. We also have approvals from UL1598, CE, FOC standards. In Taiwan we pass the runtime test of 4000 hr with a only 1% power drop and got the certificate for CNS15233. The LED street lamp is connected to our remote server that you can always adust the brightness anywhere and also receive feedbacks when the lamp is at fault. Besides the quality product we provide, we offer 2 years of warranty. For the first year if the power drops more than 7% (Taiwan standard is 10%), we can replace a new set instantly. For any one who is interested in our product, please feel free to contact us.
