Q:I have LED lights on the fluorescent lamp, and I tested it when I was running five times a dc, and four LED lights were very bright and hot,: No good. 220v is a valid value. The maximum value is 310v, and it burns instantly.I hope my answer will help you.

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:The notice of LED daylight lamp tube: Without ultraviolet light, no LED lights will not produce ultraviolet light, so unlike traditional lamps, there are a lot of mosquitoes around the light source. The room will become cleaner and cleaner. A voltage adjustable 80v-245v traditional fluorescent lamp is lit by a high voltage released by the rectifier, which cannot be lit when the voltage is lowered. LED lamps can be lit in a range of voltages, and can also adjust the brightness

Q:What is the difference between the daylight lamp tube used in fishing steel and the normal lighting tube: Ordinary bulbs are fluorescent lights, which are not the same as leds. The fluorescent lamp is the electric power of the ballast machine that produces the high pressure instantly, excited the two feet of the inside of the lamp tube to discharge, then stimulates the phosphor powder to shine. This process produces high heat. LED luminescence is an electron transfer within a semiconductor that produces light that does not produce heat. That's why leds are called cold light sources.

Q:How does the lamp line connect: Briefly said, fluorescent lamp need to shine at the beginning of the start to a transient high pressure, the pressure is greater than 220 v, ballast can produce the instantaneous high pressure, help the fluorescent lamp. Before the lamp to shine, in addition to need ballast, also need a starter starter (scientific name:), like many tubes above the starter without this now,

Q:How to choose daylight lamp? What is the light bulb specification?: The fluorescent lamp shines after normal. Due to alternating current (ac) continuously through the ballast coil, the coil of self induction electromotive force, self inductance electromotive force blocking the current in the coil change, ballast step-down current-limiting role at this moment, the current is stable in the range of the rated current of the lamp tube on both ends of the voltage is stable within the rated voltage range. Because the voltage is lower than the ionization of the starter, so is no longer the starter in parallel at each end of the work, daylight lamp specifications: general search said 50 cm, 100 cm, 120 cm. Fluorescent lamp structure and function: each has a filament on both ends of the fluorescent lamp, inside the tubes filled with tiny amounts of argon and the thin mercury vapor, tube coated with phosphor, on the wall between the two filament gas when conducting an ultraviolet, the fluorescent powder soft light.

Q:Fluorescent fluorescent lamp tube can replace led fluorescent lamp tube?: If you are not familiar with the original fluorescent lamp, you should buy the same type of led fluorescent tube, which is supposed to be T8, about 1.2m long

Q:But what happens when you don't take a ballast and replace it with a traditional fluorescent lamp?: This can also be bright, but it's also a waste of electricity and some of it doesn't have a flash of flash and it's going to light up in a flash

Q:Can a fluorescent lamp electronic ballast be powered by an led: All right, but this is something that is familiar to electronic technology.

Q:What is the price of an ordinary daylight lamp outside? That's the kind of...: This kind of fluorescent lamp saves electricity, do not have the sound, environmental protection, safety, is now a lot of family is used, ordinary fluorescent lamp is beginning to go down now
