What are the specifications for led light/led ceiling lighting ?

CE SAA cob 30w ceiling led light/led ceiling lighting cutout 150mm

Q: The top LED lights always burn the bulb in series: If the regulator is powered, it is necessary to lower the voltage

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: The color temperature of LED light string: Light source temperature is different, light color is also different:The color temperature is below 3300K, the color is red, and gives a warm feeling. There is a sedate atmosphere and a warm feeling.The color temperature is in the middle of 3000--6000K, and there is no obvious visual psychological effect in this hue, and there is a refreshing feeling. It is called neutral color temperatureColor temperature exceeds 6000K, light color slants blue, give a person with cool feeling, commonly referred to as cool color temperature.

Q: The number of lights in the LED string: 15 lights, 30 lights, and 60 lights refer to the LED band. How many LED components are welded per meter length?

Q: What's the average luminous current of an ordinary LED lamp string?: If the lamp light current series is their rated current,

Q: How does the LED light string flash?: What kind of light? What about the flash?If you are talking about the pulse drive mode of LED, then it is for heat dissipation and energy saving.

Q: What is the connection distance of the LED light string?Be specific: When the installation must be installed according to the manufacturer's requirements, do not let the LED lamp string overload operation. I use the Zhongshan Greenman, which has detailed instructions, easy connection

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!!: If it is a general common blue LED working current is 20 mA, voltage of about 2.5V can be lit, the battery power can be used in parallel, the benefits of this connection is one of the damage does not influence the normal operation of other LED. And each LED string to a current limiting resistor, LED protection lamp, prolong life, calculation formula of the resistance for V / 0.02A=: voltage current resistance: 3V, battery powered =3 / 0.02=150. You want to supply 55 LED batteries to work together, the total current is up to 0.02x55=1.1A, i.e. 1AH (ah) capacity of the battery can work 1 hours or so.
