Q:Waterproof LED lamp belt used after a period of time, there is a part of the lamp with white into orange, what's the matter?

General waterproof lights are used in epoxy waterproof, this glue easily oxidized low cost, most manufacturers are using this.There is also a silicone waterproof, this performance better, but the higher cost. Next time you buy, you can weigh and choose!The above answer, I hope to help you.

Q:How much voltage can the LED lamp withstand?

What is the voltage of the ED lamp in general? We Guanghong LED lamp electronic production with conventional voltage specification is 12V and 24V, LED 12V lamp with LED lamp is three LED for a group of 24V band is 6 LED as a group. Customers have been asked to lower the power supply voltage, but not all colors, all specifications of the LED band can be used to reduce voltage, and it can not be unconditionally reduced. To make a clearer distinction between what specifications of LED lights, the band voltage can be reduced, and first look at the 5 conventional colors of a single LED drive voltage:1, white LED:3.0~3.3V2, red LED:1.8~2.2V3, blue LED:3.0~3.2V4, green LED:2.9~3.1V5 yellow LED:1.8~2.0VThe market standard DC power supply voltage specifications are 6V, 9V, 12V, 18V, 24V and so on, then LED lights with step-down specifications must also be consistent with these specifications, otherwise the power supply matching is also a problem.

Q:PCV flame retardant material toxic? (LED background light band)

This band of material itself is made of rubber, and all the glue is with formaldehyde, want to go to formaldehyde, there are two ways, one is to buy. Activated carbon sucked, and the two is the doors and windows open, so that the room ventilation.

Q:The new LED lights are always flashing. What's the matter?

If your light belt is directly connected to the 220V power supply, this problem occurs, it must be the high voltage plug, the internal AC to DC converter is broken.

Q:What is the wattage of the LED lamp with one meter?

Each band must be equipped with a dedicated plug (plug with a transformer); when connected, be sure to remove the transparent plastic cover, and then try the lights and then cover. It must not be connected directly with a cover, so it is easy to short-circuit!

Q:LED is the light belt good? What lamp does the home outfit take well with?

Look at their own home style, what I bought the yellow light lights, but it should buy white light will be better, the yellow light is too dark, be sure to buy good quality, I did not open for three days on the flash several, my 19 meters

Q:One meter band of LED lights. Let me cut it in the middle. Then I found a thread and put it together. Why didn't it turn on?.

Then the outside two main lines also need welding.Be sure to wrap it with insulating tape. Don't short-circuit it with the outside. The outside is 220V high voltage.

Q:50 cm long LED lamp band for temporary lighting, please use AC transformer or DC transformer

Method to distinguish above products: 1, to distinguish between 220V and 12V or 24V AC power supply DC power supply, 220V products are generally comes with insert city power plug, appearance is the use of transparent protective colloid will protect the lamp, lamp with two bare metal wire section, use the built-in plug with the use of the product is high 220V lamp with; 2, 12V or 24V have direct access to LED, this is for indoor use, also has the waterproof, general products, will bring two wires are needed to connect the adapter (DC transformer), the use of the product is belongs to the low voltage DC lamp with 3, 12V and 24V to distinguish; first, the electric test using 12V, if the lamp does not light or with micro light, so, this product is the use of 24V DC power supply can be.

Q:How much is the output voltage of the LED lamp belt driver?

3V to 36V, more LED products technical problems, consult the selected lighting

Q:LED the band is cut off in the middle. Is it still bright ahead?

LED flexible light band can not be distorted during installation. If it is twisted, it will cause the LED flexible light strip to fall off and cause to be not bright.
