Q:Can normal LED fluorescent tubes be used in a vacuum?

If only the LED lamp or fluorescent tube in vacuum, and put the other circuit components in vacuum environment, vacuum sealing problem involves connecting, some trouble, if you use in a vacuum environment, the easiest way is through the optical fiber light import vacuum container, relatively simple and convenient

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

The ballast is not the condition that the voltage is raised, and when it is energized, the generator switches in the circuit, which is connected by a neon discharge tube with a capacitor

Q:How does the energy-saving lamp tube set quota

Energy-saving lamps usually refer to the light source (bulb) as a light source for energy efficiency, as for what quotas to set, and what kind of lamps the source is used for.

Q:LED daylight tube is the minimum of the W, the maximum number of W

T5 lamp tube minimum 5W, the most commonly used 11W, the product maximum 22W.I hope my answer is useful to you.

Q:What is the category of LED bulbs, T6, T8 or whatever?

In practical use, thin lamp tube is easy to conceal, use the occasion also be flexible, this is why T5, T4 light tube to get the reason that stylist people favour However, the more difficult the tube is, the more difficult it will be, so when it comes to the T5, the electronic ballast must be used to start the lamp. In order to save costs, T5, T4 of miniature stents has been adopted in the form of sale, mini space is the ballast in bracket, the efficiency and quality of the ballast are generally not very good, should lead to very high efficiency tubes as conventional T8 tubes instead of bright, life can be a little discount. Still, the lure of the tube is still strong, and the T5 and T4 bulbs are selling more and more. The difference between T5 and T4: The theory should be that T4 is efficient, but because of the quality of the ballast, many T4 is not as bright as T5. Life and stability are different, T4 is not as mature as T5, so life expectancy is slightly shorter than T5

Q:How do I get the four joints of the LED fluorescent tube, and I'm going to do any two of them that can search through the AC220V to light up, and not make the wire and the zero line together? thank you

I can't put a picture on it, you can try it yourself, add a rectification bridge at each end of the tube, and then you put the positive plus positive on both sides, negative plus negative, onto the next bridge

Q:Why don't leds and light bulbs adjust brightness by dimming switches

Dimmer switch is to adjust the output voltage, output voltage continuous variation between 0 ~ 220 v, but LED and lamp only between 180 v and 220 v to normal light, less than 180 v is not bright, so the light. The fluorescent light bulb is connected to the power supply quality of the grid, and cannot solve it.

Q:What are the types of leds?

More commonly used: T5, T5, T8. The length is 0.6 meters, 0.9 meters and 1.2 meters respectively. One is that the power of the LED tube is integrated into the lamp tube, and the purchase of the T8 is a light tube, which has no support, and will be installed with an old lamp holder

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

You're talking about fluorescent powder. Because of the high amount of Hg in the process of charge of fluorescent powder, the main source of its harm is its Hg vapor.
