Specification Tip 1: How to come to a decision the proper motive force for the LED? I met a lot of consumers and didn't understand how to make a decision the proper LED driving force First, it is best to decide the lamp's enter voltage and enter latest via 100%, then choose the matching voltage and recent of the LED driver Example: We detected a bulb voltage of 40V and a recent of 290mA So we should always choose the 8-12W 280-300mA option Tip 2: Dear buyer, if you would like a full energy LED driver, please choose 280-300 current product, this can be a complete power LED driver Tip 3: The no-load examine is forbidden The voltage is just too huge and the data is inaccurate, so make sure you enter the bulb load examine All Isolated Driver Feature The LED Driver will mechanically lit by balancing the voltage in keeping with the lamp functionality 1-3W 1-3W LED Driver (Use three years) Input Voltage: AC90-265V Load test Output Voltage: DC3-12V Output Current: 280-300mA No-load test: Output Voltage: DC19V (Danger! No-load checking out is forbidden, and the test information is inaccurate) 3-5W 3-5W LED Driver (Use three years) Input Voltage: AC90-265V Load check Output Voltage: DC9-18V Output Current: 280-300mA No-load test: Output Voltage: DC29V (Danger! No-load testing is forbidden, and the check data is inaccurate) 4-7W 4-7W LED Driver (Use 3 years) Input Voltage: AC90-265V Load test Output Voltage: DC12-26V Output Current: 280-300mA No-load test: Output Voltage: DC32V (Danger! No-load testing is forbidden, and the examine data is inaccurate) 8-12W 8-12W LED Driver (Use 3 years) Input Voltage: AC90-265V Load test Output Voltage: DC24-46V Output Current: 280-300mA No-load test: Output Voltage: DC59V (Danger! No-load trying out is forbidden, and the verify records is inaccurate) 12-18W 12-18W LED Driver (Use 3 years) Input Voltage: AC90-265V Load check Output Voltage: DC36-65V Output Current: 280-300mA No-load test: Output Voltage: DC90V (Danger! No-load testing is forbidden, and the check records is inaccurate) 18-25W 18-25W LED Driver (Use three years) Input Voltage: AC90-265V Load check Output Voltage: DC54-87V Output Current: 280-300mA No-load test: Output Voltage: DC135V (Danger! No-load testing is forbidden, and the examine information is inaccurate) 25-36W 25-36W LED Driver (Use 3 years) Input Voltage: AC90-265V Load examine Output Voltage: DC75-135V Output Current: 280-300mA No-load test: Output Voltage: DC135V (Danger! No-load testing is forbidden, and the check data is inaccurate)
