Q:Excuse me, how many different sizes for LED lamp lumens

If we assume power 5W 4 inch downlight case, assuming optical efficiency is 100LM/W, 4 inch downlight ideal luminous flux of 500LM, is on the wreck. The transparent cover is about 400 of the LM, if it is other material non transparent light cover would be lower, probably only more than 300 LM

Q:Know the LED lamp wattage

Q:Turn off the lights after the bright LED lamp

Because the electrician is working on the power off switch, the power switch is a zero line, not a live wire. Electricians know that the power switch must be cut off by the line of fire, and no danger of electric shock is announced. If the power switch is on fire line, after the power is cut off, the FireWire will continue to supply power to the LED driver. Therefore, the LED lamp will have a faint light when the switch is turned off.

Q:LED downlight downlight and how to distinguish?

LED lamp is composed of a group of LED lamp lines, each lamp line required voltage is very low, so it is necessary for certain circuit can directly used in 220V lighting circuit, the original quality of the circuit in the decision LED lamp life, general service life is several times more than ordinary lamp, price is high, energy saving and environmental protection. Is the direction of development, is to use the ordinary lamp bulb, is the most simple incandescent lamp, low voltage lamp with transformer can access 220V power.
