Is there any flicker in the LED bulb?
- First of all, I want to know what kind of LED bulb you bought. Is the LED light source small power or high power?Now on the market LED products, copycat too much, but also a lot of difference between quality and price, because the power output strobe filtering problem. Because the lowest requirements so the power design is very simple, such as shell is small power ball type PVC foam, with isolated power so far I saw several, but the price is very high, and most with the rectifier bridge, several rectifier diode, a capacitor, resistor several complete, low prices. High power type bulb is similar, but the power will be much better, is the constant current source in the output current of the filter is also doing well, there the strobe is low! Finally, the stroboscopic problem is on the power supply, and the power point difference is higher than one or two!!s
