Q:Xinda is a popular led lighting tube

Take LED lamp tube, seek the big and bright illume directly, price is certain preferential.I hope my answer will work for you.

Q:The LED fluorescent tube plus the ballast why is it still going to press?

Capacitor to eliminate the effect of the power supply of electromagnetic interference with ballast tank formation, and increase the voltage amplitude of the start pulse. An electrode in the discharge tube with double metal,

Q:If you want to replace it with an LED fluorescent tube, how many watts does it take?

If 40 w incandescent bulb lamp, LED lamp in 7 w. With the proportion of electricity savings, incandescent lamp and fluorescent lamp were similar, LED lamp is incandescent lamp energy saving energy saving 80%, energy-saving lamps than incandescent lamp energy saving in about 60-70%

Q:Why don't leds need a rectifier

Leds also require a power supply to drive only the rectifier that is not the tube. Normal LED daylight tubes are not driven. You have to have a power supply drive, and you have a built-in driver but that's going to affect the life span of the power supply and you don't have to be able to do that without the wiring.

Q:What's the difference between an LED fluorescent lamp and a regular fluorescent lamp?

Long life, easy to start, energy saving, brightness high and not easy to move eyes

Q:What are the types of leds?

The T5 is powered by a small lamp and no power supply. The component is the power supply of LED lamp tube, buy return is a light tube + a set of power supply, the installation time should use the old lamp tube support, also install the power supply

Q:How do you know whether a fluorescent tube is good or bad

There is a good or useful ballast connecting the line, and the fluorescent tube lights up, which is normal

Q:How to meet? The rectifier is very easy to connect

Went on two of the ballast with black and white and two sets of lines, a set of a tube, the last wire connects ballast is ok, if the change over time, to check whether a set of ballast to replace, so consider in ballast, if only a single change, that is about to change the bulb.

Q:How to replace old lamp tubes with LED tubes

To cut off the line from the ballast, 220V will be able to connect directly to the end of the LED tube.

Q:Is the normal daylight tube replaced by an LED line

To change! Leds are not required for electronic ballast or ballast and regenerator. It simply connects the 220V power source directly, or connects the 220V power source with a matching power module. Please read the instructions carefully before changing.
