Q:Is an LED 20 watt equivalent to 40 tubes?
Rishi's 20wLED light bulb is the equivalent of 20O light bulb, and the rest of the other CARDS I use are very bright and bright. 5WLED bulbs are much brighter than 25W bulbs.
Q:What is the idea of an LED daylight lamp called T5 or T8?
Integration tube: currently, mainly appears in the LED industry, design reason mainly lies in the fact that the LED itself is not easy to damage, but the LED heat emitted by itself is very big, if the cooling area is too small, easy to cause the droop is bigger, so will the lamp and stents design together at the same time can reduce the cost, and can ensure the LED light attenuation!
Q:How to detect the good and bad of the fluorescent lamp
The most basic and simple method is to test tubes per head of the poles, the poles are conduction description is good didn't burn out, there was a head of the poles impassability (no resistance) is burnt out.
Q:Ordinary lamp tube is replaced by the led for video
 tear down everything on the shelf, (one of them is a spin-off: the regenerator, and the inductor, the other is an open circuit board). 2: take the 220V line of communication. Another: LED tube at both ends of two light feet are interlinked, so on the bracket in the line, as long as the wire and zero line in both ends can be respectively, each side there are two shell inside, which one can be
Q:What about the quality gap between leds?
This one, you may want to consult a professional, I know that so much
Q:Ordinary fluorescent lamp ballast can be replaced with led daylight lamp tube
The fluorescent lamp tube changes LED lamp tube, need to change the line, remove old ballast and the generator, connect the power directly, because, the LED lamp tube has the power source inside.
Q:How to connect the power supply when the LED lamp is energized?
The power supply is not positive and negative, and the power supply can only work under the dc environment. Normally bought LED lamp tube has built-in power, can be used directly in the lamp holder, but should be careful to remove the regenerator, short connect ballast. You can also go to LED918 for me.
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 to choose daylight lamp? What is the light bulb specification?
The principle is: when the switch is switched on, the power voltage is passed through the ballast and the lamp filament to the two poles of the regenerator. The voltage of 220 volts immediately disassociates the noble gases of the regenerator, producing glow discharge. The heat of the glow discharge heats up the bimetal plates, and the poles are in contact. The current flows through the ballast, the regenerator, and the two ends of the filament. The filament is quickly heated by the current and emits a lot of electrons. At this point, the voltage between the poles is zero because the regenerator is closed, the glow discharge disappears and the temperature in the tube decreases. The bimetal strip is automatically reset and is disconnected. At the moment of the disconnection, the current of the circuit is suddenly cut off, and the ballast generates a large self-inductance, which is applied to both ends of the tube with the power supply voltage. The large amount of electrons emitted when the filament is heated, under high voltage at both ends of the lamp, is moving at maximum speed from low voltage to high potential end. In the process of accelerating motion, the argon molecules in the collision tube are rapidly ionized. Argon is ionized by heat, which causes mercury to produce steam, and the mercury vapor is ionized and emits a strong ultraviolet light. In ultraviolet light, the phosphor powder in the tube walls emits near-white visible light.
Q:How does the T8LED light tube replace the fluorescent lamp tube
Tube at both ends a firewire, on the other side is zero, the two feet per head are connected together, by one or two can be, if with neon bulb starter, starter can be twisted off, then remove ballast two joint together can change LED bulb.
