common problem:

1, then a good light, the LED lights kept flash, what is the problem?

Reason: LED lamp beads and power does not match lead, please consider the replacement of power or lamp beads, we shop are supporting the foot.

2, how to determine whether the original lamp is less than tile or tile?

High power is the most common cast light industrial and mining lamps, from the weight of this heat sink kit point of view, the light is not enough tile, the standard description of the top picture for your reference, the corresponding weight is the real wattage!

3, when the replacement lamp beads to pay attention to what place?

The most important thing is to wipe the previous thermal grease, because the thermal grease also has a shelf life, wipe clean our new.

B lamp beads fixed, four corners to the four screws, not less, to tighten, do not move so far, it is best to use an A4 paper to see if it can plug into the lamp beads and heat sink, Row.

C drive do not no-load test, equipped with lamp beads and then test the voltage and current, otherwise the test then then connected to the lamp beads, the voltage is too high to easily burn the lamp beads (burning rate of up to 10%).
