Q:How many lumens is the T5 bulb of 18W: Look like you do with t5 example, t5 strengths, now, now is from inductance rectifier to improve the electronic rectifier, higher efficiency, lamp lumens not only meet the even more than the national standard, reached about 90 lumens. And t5 is more efficient! If the screw lamp, generally in the luminous flux of 50-60 lm/W, and haven't consider it droop, even if Edison lamp just pack up and give a person feel very bright, but as long as a long time can tell what separates! Hope can bring convenience to a friend's life and work!

Q:Why don't leds and light bulbs adjust brightness by dimming switches: A flash is a period of time and a period of time. In a second, the human eye is not able to see more than 60 times, and can see the frequency of the flash, indicating that the fluorescent lamp is not always bright, but has the time of extinction.

Q:Are led fluorescent tubes not available for lighting?: But to see if there is a built-in power source, the external power source is not directly 220V,

Q:What is the difference between the daylight lamp tube used in fishing steel and the normal lighting tube: Again, LED tube USES long life. LED can live up to 50,000 hours (without power), and the fluorescent tube (which does not contain power) can last 10,000 to 20,000 hours.

Q:Fluorescent lamp double lamp tube wiring method: Leds that do not normally require special orders are mostly built with built-in power, which is directly available. Most can only need to remove the starter on the traditional stent line (is a cylinder bracket highlighted below) mount tubes can be used, if not yet so could you use the stent is a relatively new "electronic" will be a little trouble need you open the stents to get inside the ballast also take off to the inside of the line directly connected to the utility, LED bulb is directly at the mains. Of course, if you understand the circuit and you're not afraid of trouble, it's advisable to remove the "regenerator", because the "ballast" is a power drain.

Q:Selling LED T5 T8 fluorescent tube How do I seek customers search on the net, want to make a phone call don't know how to find customers or even who call) say specific point!!: I also do this, and now the market for leds is not very big, only companies that are looking for engineering, energy efficiency projects. Don't search for an agent.

Q:Are LED lights like regular daylight bulbs: LED lights, like many ordinary lamp belongs to the point light source, looks very dazzling, direct words must be harmful to the eyes, if from the perspective of protecting our eyes, suggestion choice electrodeless lamp, surface light source, the light is soft, is relatively good

Q:Put on the new light bulb, why the lamp still not bright: If there is a problem in the ballast itself, if the lamp filament of the inductor is red but can not be activated, most of the regenerator short-circuit damage.

Q:The circuit board in the LED fluorescent tube, what's the name of the component?: Have a what ah, whether to the power supply circuit, or light board, if do the power, you don't know now components, estimate for would you don't, schematic diagram, you seek me, send me zhang is out of date, don't mind, the new product is company secrets, if you want to power supply, it is good to look for me directly

Q:The LED fluorescent tube plus the ballast why is it still going to press?: Capacitor to eliminate the effect of the power supply of electromagnetic interference with ballast tank formation, and increase the voltage amplitude of the start pulse. An electrode in the discharge tube with double metal,
