How many watts should I buy for LED lamps instead of 75W incandescent lamps? What is the brightness?

75W incandescent bulb can be completely replaced by high-power LED 20W integrated lamp bead 35*35 chip. The lumen of each chip 35 * 35 is100-110lm20w, which is about 1800LM. Not only one company can replace corner lights, but any company can. It can be understood that if an LED bulb with a number of W or less cannot replace an incandescent bulb with a number of 75W, you should first ask the other party what kind of bulb and chip are genuine!
