Q:What is the flux of the general led daylight light
This depends on the quality of the LED fluorescent lamp, better leds luminous efficiency > 80 lm/w, that is to say, the 18 w LED fluorescent lamp luminous flux should be around 1500 lumens, 14 w flux should have over 1100 lm, 9 w flux to more than 780 lm. The poor quality is less than this flux, and there are tools that can be measured, very simple tools. There are also some quality LED fluorescent lamps that can reach this flux, and for a period of time the light is very bad, and there are a lot of poor luminescence angles that don't have the Angle of 180 degrees. LED918 has an article about how to buy LED fluorescent lights.
Q:What is the distinction between led fluorescent tubes and ordinary daylight bulbs?
Secondly, LED fluorescent lamp power is small, so compare save electricity, life is long, but the price is more expensive, and common fluorescent lamp power is great, life is not too long, will leak after crushing toxic substances, but the price is cheaper.
Q:LED energy-saving integrated fluorescent lamp tube with four interconnections in the middle
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:Is there a greater value in switching from a normal daylight lamp to an LED energy-saving lamp?
I'm selling LED lighting. I advise you to change leds, whether you're a business or a home lighting. Hand, energy conservation is certain to technical 9 w can now instead of 40 w fluorescent tube, and the price will be more and more low, you pay is very fast. On the other hand, the LED is a cold light source that does not produce ultraviolet light, and everyone knows that ultraviolet light is harmful to the human body. As service life of the original poster said this one, you don't have to worry about more, in the choose and buy when choose well-known trademark will give you three years warranty, LED life is generally 80000 hours is common fluorescent tube more than 10 times. Please take your hands on it
Q:Put on the new light bulb, why the lamp still not bright
Does your fluorescent lamp use a inductive ballast or an electronic ballast? Is the newly installed lamp tube not bright or filament red but unable to start? If the inductor is completely unlit, check to see if it is installed
Q:What is the cause of the lights after the led fluorescent lights are turned off
This is the first problem of phosphor There are residual afterglow The same way as a luminous powder By light after light This in normal LED, it is not possible
Q:How does the energy-saving lamp tube set quota
For example, can be used in dome light, wall lamp, such as the above, set directly absorb dome light, wall lamp, if only is energy-saving lamp tube directly in the lamp on the mouth, can energy saving lamp holder.
Q:The problem of LED lamp compatible ballast
Is generally not recommended to the LED lamp direct access to the original traditional lamp circuit, mainly because the ballast has power, is not conducive to energy conservation, and one more thing is if the circuit voltage instability, is too large, the prices will have impact on LED lamp power supply, generally only need to take off the ballast, on both ends of the wire can directly be connected to the can Take the answer to your satisfaction.
Q:What causes the red light on both ends
On both ends of the fluorescent lamp with a filament, when using the filament with a long time because of the heat for a long time makes its internal metal tungsten evaporates and attached to the fluorescent lamp on the wall of darkened, and so you turn on the light because the light on the wall that had led to that piece of dark red.
Q:What are the components of a T8 LED lamp tube?
According to what you said of the advantages and disadvantages of LED strips and LED lamp bead structure: 1. LED plug-in (lights) do daylight lamp, advantages: the price of the plug-in has been exactly, won't have too big fluctuations, but also has a fixed light efficiency at about 7 lm. Cons: your plugins need to be manually inserted into the board, which is slow and inefficient. The LED patch, the advantage, the full automatic production line, and the factory that does the patch packaging is many, can have a lot of choice, the automatic patch machine, the efficiency is high. Shortcomings, market changes faster, price volatility is larger It is obvious that LED plug-in without consideration, LED strips biggest market is fluorescent tube well, I'm selling ryukyu and cummings, 3014, 3014
