Multicolored RGB colr LED strip

The 5050 strip in RGB color, with the same LED gives different colors. I want to have strips with multicolor bulb on it. IS there strips models like that? Just like some of the Christmas light strings.

Beside the 5050 RGB color LED flexible strip, with 3 in 1 RGB color LED on, the RGB color strip in another form is made the strip with 3differet color LED, 1 RED, 1 Blue and 1 Green. It just likes the holiday themed light string with multicolored bulbs on. For this kind of RGB strip, by working with the relative LED controller can give different combinations of the Red, Green and Blue color.

Are these Infrared lights that you cannot see with human eyes, or are they LED’s that light up?

Are these Infrared lights that you cannot see with human eyes, or are they
LED’s that light up?

The Infrared (IR) light is electromagnetic radiation with longer wavelengths than those of visible light, which is not visible as they are in extending from the nominal red edge of the visible spectrum. The LED lights made with the Infrared LED cannot see with human eyes. The similar example we always meet in our daily life like the security camera, the Infrared LED are used in this device.

WiFi controller solution

I have a case that need to use 3 LED strips nearly but in 3 different places in a same space. For limitation, between the 3lights, no wire can be used. And the 3pcs strip have to be able to work synchronously. SO I want to look for if there is wifi choice for my application.

Two choices are available.
Option #1 Use the 1Master wifi controller and 3Slave WiFi controller, and controlled by your Smart Mobile Phone with the software comes along with the wifi controller package.
For this solution, the Master controller cannot be used to run strips, so for 3strip, need to use 3Slave controller.


Option #2 Use 1Master WiFi controller and 2Slave WiFi controller, and controlled by the Remote comes with the Master WiFi controller.
For using this solution, as for the Master controller can use to load 1pcs strip, so only 2Slave controller.


The battery and the charger

The LED flashlight, some of them use the 18650 chargeable batteries, but there is a small model that uses the 14500 battery. For the charger, how can I use the 18650 charger provided to charge the 14500 battery?
A simple way is to use the fake battery, which also can be named as the extension contact. PLS find below the explanation about how to use the fake battery to reach the target.





What type of voltage and current do LED lights require to operate?

Conventional incandescent lamps are made to operate on standard AC power. Descrete LED chips themselves are designed to operate on DC current typically in the 350 mA range. As a result LED bulbs are designed with built in AC to DC converters that supply the correct current needed for the specific LED chips. LED lights may be used in place of traditional incandescent lamps without changing the fixture. Please note that most LED lights are not designed to be used with dimmers. Do not install an LED bulb into a dimmer controlled circuit with a properly designed LED lamp.  Flourescent Tube lamps operate with a specific ballast. To install a T8 LED tube replacement, the flourscent ballast fixture must be removed or bypassed to provide the standard direct connection of the 110 VAC power to the T8 LED tube.  One end of the tube receives the positive and one end receives the nuetral.

Why is LED lighting better for the human eye than fluorescent or incandescent lighting?

The human eye is constructed for viewing our world in the broad spectrum of natural sunlight. LED light transmits 90% of the sun’s spectrum, and is far closer to natural light than fluorescent, incandescent or induction lighting. LED light allows people to see the true color of objects and their surroundings, making it an ideal choice to display products in the best possible light – literally.

Can the LED T8 tube be used outdoor directly?

If T8 tube will need to install outdoor location where the tube will be sprayed by water or immersed in water shortly, there is waterproof tube with protection grade up to IP67 fit for these cases. The waterproof tube two end are protected by waterproof plastic nut and cap, wires out and can fixed by screws at two ends.

What is compact fluorescent? What is the difference between compact fluorescent and LED lighting?

The compact fluorescent is basically the same as a fluorescent tube. It reaches its maximum brightness in 1-2 minutes after turning on. Fluorescent lamps and compact fluorescents are designed for persistent use. Too many switching on and off can cut down the already short lifespan of a few thousand hours. LED differs from compact fluorescents in two main areas: it uses about 50 % less energy and constant switching does not affect its lifespan.

What transformers are the most suitable for LED lights?

Electronic transformers do not work with LED lights. When replacing your transformer / power supply with a new one, we strongly recommend you purchasing a dedicatedLED power supply / transformer. The right kind of transformer is an investment to guarantee the maximum lifespan of the LED lights. This would need to be a constant voltage LED power supply / transformer.Unlike electronic transformers, commonly used for halogen lights these do not have minimum load requirements, but do have a maximum so make sure the sum of Wattage used by your LED lamps or lights is less than the maximum rating of the LED power supply / transformer. To maximize the efficiency and lifespan of your LED transformer keep the total power consumption close to 80%.
Please note: LED power supplies / transformers are design specifically for LED lights.

What’s the difference between Constant Voltage and Constant Current drivers?

With Constant Voltage the LED module only requires a fixed voltage, often 12VDC or 24VDC. The current is usually regulated by either resistors that have been wired in series with the LEDs or by an onboard built-in regulator driver that the LED module may have. This arrangement is often used in signage where it is not known prior to the installation how many LED loads there will be and in linear architectural designs where there are a number of LED modules connected together. Constant voltage loads may be added in parallel across the output of the driver until the maximum output current is reached.
With Constant Current the reverse is true, the current is fixed by the driver while the voltage will vary depending on the load. The more LEDs are attached, the higher the output voltage will be, up to a maximum set by the driver. This is usually used when the load/number of LED’s is known and you want optimal efficiency, as in a recessed downlight or track fixture.

How can reach that effect?

What I am looking for is a 2 LED kit, 1 red 1 white. That I can go from strobe to fixed white or fixed red. How can reach that effect?

We can use:

1x white LED light

1x red LED light

1x 24key IR RGB controller


The LED light, you can use 12V LED flexible strip in White and Red color, or other 12V LED lamp. There is a lot of the strip choices, in below link, we can find one suitable.

The 24key IR RGB controller is like below.


Connection of the kit

Note: The RGB controller has 4channels, one for + poles; the other 3 are all – poles. You can use any two of the – poles. And the kit suggest here is 12VDC operating, it need c to run.

Now after you connect the LED and controller like this, then you can use the remote to reach the effect you want.

What is the difference between Watts, Amps and Volts?

We measure electricity by it by its effects on applications. An Amp (amphere), represents the amount of current in a circuit. Voltage, scientifically is the circuit’s “potential difference,” and this can be seen as the amount of “pressure” that drives electricity in circuits. Watts measure the use of electrical power, and 1 Watt is equal to 1 Volt, multiplied by 1 Amp. To understand this better let’s think if it like this… One commonly used analogy is that of the garden hose. The water pressure in the hose represents the voltage, and the amp value represents the volume of water flowing through the hose. The wattage, then, is the total amount of water that comes out of the hose, per unit of time.
So, using this analogy and think in terms of an electrical wire, it is simple to see how they relate. In an electrical circuit, the voltage may be 240v (as it is in most electrical outlets in the United Kindgom), and most appliances are set to run on this particular voltage, although each individual item will operate at different Amp levels, and therefore at a different Wattage.

What is the lumen of the led strip

Total leds multiply by lumen of each led, then to multiply by 0.8 which is the lighting effect for the milky white cover, and to multiply by 0.9 which is lighting effect for transparent cover. For example,T81.2 milky white cover,276pcs leds. Each leds is 6-7Lumen:276*6.5*0.8=1435.2.


Remarks: luminous flux=qty of leds*Luminous*transmittance. The qty of the led is consult, and the luminous is affected by drive current, CRI and color temperature. The small driver current,. The luminous is small. High CIR, then small luminous. The high color Temperature, then big luminous. Light transmittance is also changing. There are several kinds of material for the cover, like PC, PMMA, plastic, etc. The light transmittance of the plastic can reach to 97%,and the light transmittance for the PMMA can reach to 93%, the light transmittance for the PC can reach to 90%,which means the light transmittance through transparent or translucent body with its the percentage of the incident light flux. Milky white cover with lower light transmittance. That is to say light transmittance=the material of the light transmittance*(1-dimness).
