LED floodlights dismantling evaluation power virtual standard is what is going on?
Domestic LED lamp power imaginary standards have become the industry's routine, the general actual power is more than two-thirds of the nominal power, so it is still acceptable, buy more power on the line. However, I have been shocked by the fact that I recently bought an LED floodlight with a virtual power of more than 5 times. If you need real power, then it is basically useless to buy it. Therefore, it is necessary to let everyone know about this special situation. When buying this kind of lamp, ask the actual power, so as not to buy it back.
Nominal power 100W
Adopt 102 5730 lamp beads, each lamp ball is 0.5W, and the full power should be 51W. Two-thirds of the power should also have more than 30 W.
But the actual measurement is less than 18W
The plastic in the back, the heat dissipation conditions are not good, it is estimated that this is the reason for reducing the power.
The lamp circuit is a typical capacitor step-down circuit, the operating voltage is 150V, and there is no constant current function.
The projection reflector and heat sink are very thin, so they cannot withstand more than 20W.
