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

Q: The top LED lights always burn the bulb in series: A simple circuit based on resistance current limiting can only be adjusted with current resistance.

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: Now the market has launched a LED string lamp controller. Professional rainproof. You should be able to buy it at the big mall!!!

Q: The color temperature of LED light string: Refers to a standard blackbody heating, the temperature rises to a certain degree when starting from the color red - Orange - red - white - blue, gradually changed, a light source and the blackbody with the same color, we will at the time of the absolute temperature blackbody called the color temperature of the light source.

Q: 220vled water lamp string how to connect, that is, 220 of the electricity: The time of the water lamp is controlled by adjusting the capacity value of the capacitor.

Q: Performance and characteristics of LED lamp string: 1.LED lamp string can handle perforation lamp string processing;2.LED lights string may through seven colors and full-color controller to achieve colorful jump, gradient, monochrome, full-color, fluttering and other effects.

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: Diode products cannot be calculated by resistors.

Q: What is the connection distance of the LED light string?Be specific: The connection distance is 15 meters. If the connection distance is exceeded, the LED light string is easy to heat, and the service life of the LED light string will be affected during use

Q: Why are there three lines for the controller of the LED light string? What are they?: The four cycles are green, blue and white, and the answer is almost the same as that on the top. But the three colors are strung together

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
