Q:LED soft light with color temperature 2400k what do you mean?

LED soft light with color temperature 2400K meaning: LED color temperature parameter is 2400K, color temperature generally press 3000K warm white 4000K, white 6000K, cold white points. 2400K color warmer, suitable for places requiring lower color temperature.

Q:5050LED lights with 14.4W/1 meters, power 12V-360W can take 25 meters? I mean RGB, if it's connected to the color

Reckon the power: 14.4*25 = 360W, see power and power on the surface is the same, this is actually a problem, make full power power, it's easy to burn, only half done, it is recommended to use two power.

Q:Is the LED belt with a constant voltage transformer or a constant current transformer?

Constant current transformers are generally current transformers. The principle of current transformer is based on the principle of electromagnetic induction. The current transformer consists of a closed core and windings. The number of the primary winding turns its little string in the current need to measure the line, so it is often all two line current flows through the primary winding turns are more connected in series of measuring and protection circuit, current transformer in operation, the two side loop it from the beginning to the end is closed, so the measurement instruments and protection circuit impedance in series with the coil current transformer is very small, close to the working state of short circuit. The current transformer is to change the primary side large current into two side small current to measure, the two side can not open circuit.

Q:Which is good for low voltage lamp belts 5050 and 3014?

Power connection method: LED lamp belt voltage is 12V DC, so it needs to use switch power supply, the power supply size according to the power of LED lamp belt and connection length to decide. If you do not want to take each LED lamp with a power to control, switching power supply can buy a relatively large power for the total power supply, then put all LED light with all input power in parallel (wire size is not enough, also extended) unified by the total power switch. The advantage is that it can be centrally controlled, which is not convenient. It can not be achieved with the lighting effect and switch control of a single LED light band, which can be measured by itself.

Q:LED how to distinguish between good and bad?

Look at the label. Regular LED lights, bags, and rolls have printed labels, not printed labels. The Shanzhai version of the label is printed, while specifications and parameters are not uniform.

Q:LED lamp and lamp with high and low points?

LED lights to light, you must have a power drive, high voltage means to connect high 220V use, with internal power driven.

Q:LED soft light belt?

Provide the following installation should pay attention to the details of several lights for everyone: 1. power connection method: general voltage LED lamp with DC 12V, necessitating the use of switching power supply, power supply according to the size of the power LED lamp belt and connected to fixed length. If you do not want to take each LED lamp with a power to control, switching power supply can buy a relatively large power for the total power supply, then put all LED light with all input power in parallel (wire size is not enough, can also extend) unified by the total power switch. This advantage can be centralized control, inconvenient place is unable to achieve a single LED lamp band lighting effect and switch control, which specific way to be measured by their own. 2., each meter has "scissors" mark, only in the mark must be cut, scissors or scissors will lead to one meter does not light, it is best to carefully look at the location before the mark, according to the middle of the connection can not cut it.

Q:What is the minimum number of light bands?

LED lights with 12V meters, there are a variety of power, the common 5W to 20W, such as: 3528LED, 30 led per meter, power per meter 2.4W; 60 led per meter, 4.8w per meter. 5050led, 30 led per metre, 7.2W per metre, 60 led per metre, 14.4w per metre. Led band power calculation method: power is the measurement of energy transfer rate, in dc...

Q:Which of the 12 volt LED light band and 220 volt LED lamp is brighter? What's the difference in electricity costs? Want to use it in the mall counter, 12 volts

First of all, I doubt this lamp seller really understand it, can use 12V lights with constant voltage power supply 12V, you do not know this lamp with 1 meters is the number of W, generally 1 meters 30 meters 10W, that is 300W, you can buy a 300W constant voltage power supply, positive and negative with positive and negative light with constant voltage output, is very simple, do not worry about the brightness of the problem, as long as you do not exceed the constant power load. As you said, 220V lights, 220V lights directly connected with no real meaning, is the need to add an adapter in front of the adapter is 220V, this adapter is actually a driver.

Q:Led how much is the price of the lamp?

LED lamp belt price is according to its quality to evaluate, poor quality a few dollars a meter, good quality of more than ten dollars a meter, recommend the use of photon lighting technology, LED lamp belt, there is always a LED light belt for you.
