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:What causes the red light on both ends

There are two kinds of red light on both ends of the fluorescent tube: 1, if it is the use of long tube, gradually from both ends of black, red in the end, there is a gradual process, is basically a lamp aging, filament will burn out the precursor, exchange tubes can troubleshooting; The lamp tube USES all the time normal, occurrence afore-mentioned phenomenon suddenly, that most is the rectifier is caused by failure, change rectifier can.

Q:The LED fluorescent lamp tube breaks the LED light in the inside

If this is not bad, then look back, there should be a small power supply at the end of the aluminum plate, and the other end of the power supply is 220V. Another possibility is that lower-end LED products will be blocked (non-isolated). Is the aluminum substrate in addition to the SMT chip, also some electronics posted above, if the aluminum board intact, you also to the end, one 220 v mains interface on both ends

Q:Does the home led tube have ultraviolet light

It's not a trick to say, but don't be afraid, most artificial light sources are there, and there are only a lot more than leds, like fluorescent lights, energy-saving lamps... Today with the changing of science and technology, the led is far better than in previous years, the quality of the purple light damage has become the past, it's just that some merchants traditional lamps and lanterns of advocacy for himself only often hang on the nozzle

Q:Is an LED 20 watt equivalent to 40 tubes?

There are several kinds of white color temperature, warm white, is white, cold white,,, generally are on the market is more white, warm white, yellow,,, nothing is harm to human body, there will be no ultraviolet rays,

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:Can fluorescent tube T5 and LED T5 be connected in tandem?

The main difference is the support of built-in and interfaces, such as fluorescent T5 is to use electronic rectifier, LED with constant current device, etc., don't change stent must not, even the stents in together, must be allowed, are in parallel in the circuit.

Q:It is the telephone of some enterprise management that asks me to take good use of, ask me how to use, how to contact them, what should I say when contacted I am a salesman

A lot of business today is telemarketing. 30 call a day is normal, this is to exercise their own, do not be afraid of failure, don't be afraid of rejection, specifically how to say, you can please teach you first job-seekers, observe how old colleague telephone communication

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

The specification of fluorescent lamp is the diameter of tube, length. Look at your lighting requirements, T8 pipe size, of course, the light effect will be better, the same length of lamp tube T8 will be more than twice as bright as T5, and the brightness is much better. The quality of the lamp is not so good at present. The main view is lamp tube with light, electric power and heat dissipation processing.
