^{1.How to deliver goods?}

^{We offer worldwide delivery services, Goods is delivered by your appointed forwarder or our appointed forwarder, seaway, airway,land transportation are all available.}

^{2.What is the warranty policy ?}

^{We provide you with 3 years warranty for all of our products, if the product does not work very well, we will replace them with new one free of charge, but shipping cost will be at your side if you are not in China.}

^{3.What is LED light and its features ?}

^{LED stands for Light Emitting Diode. LEDs are a energy efficient form of light energy that can be used for a variety of lighting applications. The beneficial features of LED lights are endless. They use far less electricity than traditional lighting, have an extremely long lifespan, they are resistant to shock and vibrations, they are specialised bulbs manufactured to operate effectively in extreme environments, produce a minimal amount of heat, contain no mercury and they do not emit UV or infrared.}

^{4.How long LED lights last ?}

^{The average life span of an LED lights is up to 50,000 hours, which is 5 years of constant illumination - this means that once you have installed you may never have to change the lights unlike incandescent light bulbs and halogen lights.}

^{5.Why use LED driver ?}

^{An LED driver will save your LED lights from any damage that can be caused by a standard electronic transformer, which may potentially shorten the life span of your lights as well as cause them to flicker as the transformer is not providing a smooth flow of current.}

^{6.Can LED lights be used with Dimmers ?}

^{Yes, in order to use dimmers you will need to purchase the dimmable lights. As well as this, You may also need to replace your existing dimmer with one that is suitable for LED lighting.}

^{10. What are Lumens ?}

^{LEDs are described in lumens (Lm) as this is the scale used to measure the brightness of thelight, as opposed to the wattage (W), which demonstrates the amount of power that is consumed; because LEDs consume such little power, using lumens gives a clearer idea of how bright a particular light  will be.}

^{7.What does it mean by Efficacy ?}

^{Efficacy describes the ability in which something can produce the desired result - in LED terms, this means the amount of light that is produced per the given amount of energy, for example Lumens per Watts (Lm/W).}

^{8.What is CRI ?}

^{The Color Rendering Index measures how much of an effect the light has on the perceived color of an object. The scale ranges from 1 to 100. A higher rating makes colors look natural and vibrant while a low rating can completely change the hue of objects. A high CRI alone does not mean colors will be accurate if the color temperature is extreme. Incandescent bulbs for example have a perfect CRI of 100, but the extreme yellow light will shift the colors.}

^{9.What is Color Temperature and its Rating ?}

^{The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that of the light source.Color temperature is a characteristic of visible light that has important applications in lighting,Color temperature is conventionally stated in the unit of absolute temperature, the Kelvin, having the unit symbol K. Warm White: 2700K-3000K, Neutral white: 3000K-5000K, Cool white: above 5000K.}

^{10.Do LED lights flicker in normal usage ?}

^{LED lights are non-stroboscopic, they should not flicker in normal day to day usage.}
