The color temperature of cool white is between 3500K and 4500K, and the color temperature of warm white is between 2700K and 3200K. Cool white is more inclined to natural light than warm white light, such as the color of sunlight at noon. Warm white is a more soft, warm color.

One of the biggest advantages of LED lights is their energy efficient performance. Compared with traditional incandescent and fluorescent lamps, LED lamps use less energy but produce more light efficiently. Specifically, the energy efficiency of LED lamps is about 80-90% higher than that of incandescent lamps and about 50% higher than that of fluorescent lamps. This means that at the same brightness, LED lights consume less electricity, which significantly reduces electricity bills.

Compared with traditional lamps, LED lamps are more energy efficient, long lifespan, environment friendly, high energy efficiency, fast response, soft light, small size, light weight, easy dimming, color temperature and power adjustment.

LED (LightingEmittingDiode) lighting is a light-emitting diode lighting, is a semiconductor solid light emitting device. It is the use of solid semiconductor chip as a luminous material, in the semiconductor through the carrier composite release excess energy and cause photon emission, directly emit red, yellow, blue, green light, on this basis, the use of the principle of three primary colors, add phosphor, can emit any color of light. The lighting appliance made of LED as a light source is LED lamps.

LED lights after a long time of operation, it will getting hot, but it is a normal phenomenon, because its heat needs to be distributed, usually LED lights are with heat sink, heat through the heat sink is emitted, and then maintain the life of the LED lights, bad heat dissipation LED lights will appear dead lights and other not bright phenomenon.

‌LED color rendering index (CRI) refers to the ability of the light source to restore the color of the object. The higher the value, the better the color rendering of the light source, and the more truly the color of the object can be restored. ‌ Color rendering index (CRI) is evaluated by comparing the color of an object under a light source with the color of an object under a reference light source. For indoor lights, the CRI must be higher than 80, sometimes, it requires CRI>90, for outdoor light, it can be 70.

‌LED lumen refers to the perceived energy of the human eye radiated by the LEDs in the surrounding space in unit time, usually in lumens (lm). ‌ The lumen value of LEDs of different colors and powers varies, the main calculation method of LED lumen value ‌ is based on the calculation of light efficiency and power ‌ :
Formula: ‌ lumen = luminous efficiency (lm/W) x power (W)‌‌.
Description: Light efficiency is the luminous flux generated per watt of electrical power, power refers to the electrical power of LED.

LED light color temperature refers to the light wave in different energy, human eyes feel the color change, in the calculation of color temperature, Kevin as a unit, common color temperature including 2700K,3000K,4000K,6000K and so on. Among them, 2700K and 3000K are warm white, 4000K is cool white, and 6000K is day white. At present, some of our products can make 3000K,4000K and 6000K color temperature adjustable.

LED lights perform well in terms of safety. Its high safety, has the advantages of good energy saving, long life, not easy to break and so on, the luminous principle of LED lamp and ordinary fluorescent lamp is no essential difference, normal use is very safe.

The lifespan of LEDs (light emitting diodes) is usually between 25,000 and 50,000 hours, depending on a variety of factors, including the use environment, temperature, humidity, and the number of switches. The life time of the LED bulbs or LED lightings is generally between 30,000 and 50,000 hours. In theory, the life of LED lights can reach more than 100,000 hours, but in actual use, due to the influence of various factors, its life may be shortened.

IP refers to the waterproof rating, generally in outdoor or bathroom and other humid environment need to use IP Rated lamps, usually the bathroom with IP44 or IP54 rated lamps, outdoor eaves are generally IP54 or IP65 or above, underwater use, generally IP67 or IP68.

LED light is a very energy-saving, environmentally friendly lighting, LED light brightness will not directly damage to the eyes, but for a long time under too bright light will cause a certain degree of discomfort and fatigue to the eyes.

Ultraviolet and infrared rays generally cause damage to the eyes, and the light generated by LED lights does not contain ultraviolet and infrared rays, so under normal circumstances, LED lights do not directly cause vision loss or damage.

Yes, you can cut light strip by yourself, normally the LED strip input voltage is 12V or 24V, and the light tape will come with scissors icon, then you just cut it at the icon.

At present, the LED bulbs have nearly the same price as the traditional incandescent and halogen light bulbs, and the prices of other LED fittings or fixtures may be slightly higher, but in the long run, the LED lamps are thought to save money, because the LED lighting is more energy efficient and has a longer lifespan, LEDs are 90% less energy, incandescent and halogen light bulbs only last to 2,000 hours. LED lanps can last up to 50,000 hours.

Yes, the LED lights will heat up after a little time, but do not worry, the LED lights have their own heat sink, it will dissipate the heat, so that the led lights continue to work well.

Shenzhen lighting factory's main products are industrial lighting, such as high bay, tunnel lights and street lights, because the environment and incentive system is better, the sales in Shenzhen often provide more timely and better customer service. Ningbo is mainly based on tri-proof light, they produce tri-proof light fixtures or LED tri-proof lights. Most sales are from local, due to small economic pressure, the customer service awareness is not strong. Zhongshan mainly in decorative lighting, many companies can only provide product pictures and prices, it is difficult to provide detailed product specifications and other information.

There are 3 quickest ways to get to Shenzhen from Hong Kong Airport. The first option is by Ferry, at the Hong Kong airport there are direct Ferry to Shenzhen Shekou border ports, no need to go out of the customs, half an hour to reach Shenzhen Shekou border ports. Just follow the directions to the ticket counter. The ticket price is 280RMB. The second option is to take a taxi directly from the airport to various border ports in Shenzhen, which costs around HK $300 and takes between 45 minutes and an hour, depending on traffic.
The third option is to take a commercial bus to various ports in Shenzhen, which costs from 150 Hong Kong dollars and takes 45 minutes to an hour, depending on traffic.

In China, there are three large-scale lighting exhibitions, one is the Hong Kong Lighting Fair, the second one is Guangzhou Lighting Fair, and the last one is the Canton Fair. Hong Kong exhibition is divided into spring lighting exhibition (from 6th April to 9th April every year) and autumn lighting exhibition (from 27th Oct to 30th Oct every year), a majority factories or buyers will choose to go to the autumn lighting exhibition, because nearly all of exhibitors are doing export business, autumn lighting exhibition generally has more than 3000 exhibitors. The second one Guangzhou Lighting Fair, it also has more than 3000 exhibitors, but a large part of them do not export directly , but you can find some unexpected products in this fair. Finally is the Canton Fair, Canton Fair, LED lightings are only part of it.
