Q:The T8 nominal 36W standard daylight bulb is only 18W

This problem is the output power of the ballast for not doing enough, main is not the problem of power factor. For the electronic ballast, the output of active power is low, requirements for the switch tube is low, can use low or inferior triode, such costs are lower. In addition, the output inductor can also be less a few rounds of copper wire, cost is low. So do electronic ballast to make money. The upstairs have their own design of electronic ballast

Q:The difference between LED and fluorescent lamps

LED is a solid-state light source that has a long life and is environmentally friendly and efficient, and leds are now safer.

Q:20 square metre room application which led fluorescent lamp tube

But if the family USES it, you can use the light bulb 100 percent for aesthetic purposes

Q:The child lamp chooses led good or the lamp tube is good

All can be LED with the natural white light bulb (osram), the lamp tube with three base color. From the protection of sight, try not to read for long periods of time, take a proper rest, look at the distance and move your eyes

Q:How long does the energy-saving daylight lamp tube change?

You didn't say you were satisfied with the brightness you had just installed three years ago. If the brightness drops only if the brightness decreases with time, replace the lamp with a reduced brightness in time.

Q:The light tube is directly connected to the zero fire line at 220V, and the other end is empty

You are good for nothing! It's nice to be complimented on the quality of your air switch.

Q:This kind of fluorescent tube is always easy to burn.

The ballast of fluorescent lamp (fire ox) quality is not good, change him a new be ok!

Q:What is the minimum starting voltage for the fluorescent tube?

The minimum maintenance of a fluorescent tube is 100V volts. 2 · the fluorescent lamp is in qi hui instant, the rectifier load voltage is 800 volts. (the function of the ballast). This 800 volt voltage is transient and can be observed with a digital oscillograph, and the 800v voltage is observed through the digital oscilloscope. I don't have any real data.

Q:Is it healthy to hang a towel with a bad fluorescent lamp

Mercury vapor reaches 0.04 to 3 mg, which causes chronic toxicity in two to three months. An increase of 1.2 to 8.5 mg can cause acute mercury poisoning, and if it reaches 20 mg, it leads to death.

Q:Led lamp tube t8 good or t5 good

This depends on where it is used, and the average household or supermarket store is using a t8led lamp. The t5 lamp is used in special places
