Taiwan 20w 2100lm DLC UL Listed T8 Tube 4ft LED light

Q:LED lights string broken, how to repair?: Connect the electricity. Can be shorted one by one. It's shining. This is just short of bad beads.

Q:The number of lights in the LED string: Different LED number of LED light band price is different, and this is also to distinguish LED lamp belt price is an important factor.

Q:How much is the voltage across the 20 LED lamps in series?: Don't know what kind of LED, if it is ordinary bright LED words, according to different colors, the rated voltage between 3.6-3.8V (current allowable level <20mA), you can be calculated according to the amount of estimates, as long as the control current should not exceed 20MA no problem

Q:Hanging on the tree string lights, each one is 10 meters long, with a controller, I asked the factory with the AB protection, but the manufacturers say that only do the general anti rain, no water, even the rain stop, I want to use plastic wrap, don't know? Which expert can give advice and advice? emergency: You can use the plastic wrap, mouth down, so even if again under the rain is not bad. Or glue the entire controller to the point where the water is likely to enter the water.

Q:I want to do a string of LED lights that can use batteries. About 55 or so. The lights are 5MM blue. How can I work? Urgent urgent!!: 55, it is blue, blue and white as the power is too large, large power consumption, even in parallel connection, the voltage of 3V certainly do not move with the battery, just to be able to provide 4.5V voltage, and three batteries of 5 words for a while no electricity, regulated power supply with advice, use parallel to, from the 3V voltage can be gradually increased, the brightness is just perfect, too high voltage lamp

Q:Led full-color light string and how to control wiring: 5 line DMX512 full color string, 2Po, 2 access, and access control site

Q:How do you connect the LED lights?: A series of even parallel. Are not clear, boss, you want to use LED do what?There is a gap, which is the positive pole of the LED (usually the long foot is short and the foot is negative)

Q:Example: if I want to do a 40 head low voltage lamp string, do 10 lights, 1 loop, transformer is 150MA, then how can I calculate the resistance? The grid is 60 Hz of China's power grid! Give a formula, and then count the examples. What is it?! Thank you: In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.

Q:The color temperature of LED light string: Generally speaking, the color temperature is not an indicator of the LED band, but many foreign customers will make a special request because of the use of the environment.

Q:Why are there three lines for the controller of the LED light string? What are they?: 65 of the LED tubes are connected with 3-4 resistors. One end of the resistor is connected to the positive electrode of the LED, and the other end of the resistor is connected to the common anode of the controller. The blue wire is attached to the negative electrode of the LED tube.
