This product is made up of three 3watt high power LED, but working under 400-420MA, actual power consumption 2watt/LED. Our E27 6 Watt LED DownLight is an LED DownLight that replaces a wide variety of halogen and fluorescent lighting with a green, efficient, longer-lasting LED bulb that is comparable in size. Available in non-dimmable and dimmable version, you can use this bulb with the traditional incandescent dimmer. This bulb has a common screw mount base that fits directly into your existing socket and will fit into any place that a CFL will, while reducing maintenance and energy costs and providing a warmer, steadier light. It also holds the prestigious RoHS (Restriction of Hazardous Substances) certificate, which states that no toxins or harmful materials were used in its production.
Common failures and trouble shooting:
1. If the lamp does not light, check if the power supply is connected, switch is in position. (Note: lighting and constant-current source DC plugs must be connected to the junction box, and an external power supply, or LED bulbs will burn out. )
2. when the lamp on and off on times, check if the power supply is bad or loose.
3. If the brightness of the lamp is not enough, please check if the voltage is normal.
Advantages of the LED bulbs:
l High energy-saving: saving energy is a pollution-free environment. DC drive, ultra low power consumption (0.03-0.06 Watt single tube) electrical power conversion near 100%, same lighting effect than traditional light sources than 80%.
l Durable: LED some people refer to it as a long life lamp, meaning the light that never dies. Solid cold light source, epoxy resin encapsulation, lights and no loose parts in the body, there is no filament light burning, heat accumulation, failure-prone faults, service life of up to 60,000 to 100,000 hours, more than 10 times longer than traditional light source life times.
l Various Changing Effects:with red, green, basket trichromatic theory, under computer control three colors with a 256-level grayscale and any mix can produce 256x256x256=16777216 colors, different combinations of light color changing, achieve dynamic effects, and a variety of colorful images.
l Environmentally-friendly: environmentally preferred, ultraviolet and infra-red spectrum does not, no heat, no radiation, low glare and wastes can be recycled without pollution does not contain mercury, cold light source, is safe to touch, is typical of green lighting.
l High-Tech Tip: with the traditional light source compared to the dull glow, LED lighting is low voltage micro-electronics products, successful integration of computer technology, network communication, embedded control technology, image processing technology, so is digital information products, semiconductor optoelectronic devices “high angle” technology, with online programming, unlimited upgrades, flexible features.
l Changing effects and all kinds of images.
l Wide Voltage Range. 85V~264VAC voltage range constant current to ensure longevity and brightness are not affected by voltage fluctuations;
l No Strobe: pure DC work, eliminating the traditional light source of Visual fatigue caused by strobe;
l High security: low voltage work, safe and reliable. Surface temperature of 60 ° c (ambient temperature Ta=25 ° c);
l High Light Efficiency: lighting effect reaches more than 100 lumens/Watt, 4 watt LED bulb light equivalent to a 45-watt incandescent lamp;
l Excellent Impact Resistance: resistance to lightning and strong, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass enclosure, no traditional lamp fragmentation problem, no harm, no radiation on the human body.
Luminous flux (LM)
Because the human eye to different wavelengths of the electromagnetic waves have different sensitivities, we cannot directly radiated power or radiant flux of the light source to measure the light energy must apply to the human eye to light feeling—-flux quantities as the base units of measure. Luminous flux is represented by symbols φ, in lumens (LM).
Luminous intensity (CD)
Luminous flux is the demonstration of a space around the light source to emit the total light energy. Different light sources of the emitted luminous flux distribution in space is different. Unit of luminous intensity candela, symbol for the CD, it says in a unit sphere the solid angle of the light source (the surface on the formation of point light source point) in the emitted luminous flux. 1 CD=1 LM/1 SR (SR: solid angle of a sphere of unit).
Brightness is the eyes see objects emitting light intensity in one direction. Unit candela/square meter [CD/m2], symbol for l, indicates that the light in a particular direction of luminous flux per unit of solid angle per unit area, it equals 1 square meter on the surface a 1 candela of luminous intensity.
Color temperature (Color Temperature)
When the light source causes a light color and the color of the blackbody radiation at one temperature is the same as the blackbody temperature is known as the color temperature of the light source, with the absolute temperature in k (Kelvin, degrees Kelvin = degrees +273.15).
Color (Color rendering property)
In principle, the artificial light and natural light are the same, so that people can correctly identify the color of things to the naked eye, of course, that according to the location and purpose of the lighting.
Degree of color rendering of light source for objects is called color. Usually called “color-rendering index” (Ra). Color is something true color (color of its own) and a display of color under standard light source. Ra value determined, are defined in the DIN6169 standard of 8 test colors under standard light source and light source being tested in comparison, smaller difference indicates that the measured color rendering of light color, the better.
