Why should I use LED Lights?
LED Lights consume 80-90% less energy when compared to the equivalent incandescent or
halogen light bulb. See the chart below for a comparison to incandescent bulbs.
Incandescent (Watt) | LED (Watt) |
| 25 | 3 |
| 40 | 4-5 |
| 50 | 5-6 |
| 60 | 6-9 |
| 75 | 8-10 |
| 100 | 10-15 |
| 120 | 15-20 |
How much will I save using LED Lights?
If a 6W LED light is used to replace a 60W traditional incandescent bulb then the savings
will be 90%. The Chart on the Savings Page shows other savings.
What is the life of an LED Light?
LED lights have a theoretical useful life of over 50,000 hours compared to a useful life of 6,000 to 15,000 for sodium lights and fluorescent tubes and 1,000 hours for a traditional incandescent bulb or spotlight. Some LED lights will continue to operate up to 100,000 hours.
LED Lights are expensive. Do I really save?
LED's are great value.The payback period of the initial investment of the LED bulb is typically 6 to 24 months. Thereafter you will save on the reduced electrical consumption. In addition, you will not pay for the replacement cost of lamps, and replacing bulbs in hard to reach places.
Why should I switch to LED lights?
First, LED lights are 60 to 90% more efficient than traditional bulbs, thus saving electricity. Second, LED's do not contain harmful gases or mercury. There is a concern for the proper disposal of many traditional bulbs. Third, traditional lamps have a useful life of 1,000 to 15,000 hours. LED's last up to 50,000 hours and can be designed in different shapes and can emit varying colours of light depending on the users preference.
Did you know the incandescent bulb will soon be obsolete?
LED's will become the lighting technology of choice due to its lighting efficiency, long life, and lower cost of ownership benefits. The UK already has legislation to ban incandescent bulbs in various forms starting 2010.
What are the environmental benefits?
23% of the electrical consumption in the world is used on lighting. A substantial amount of energy can therefore be saved by converting to LED lights. Since the primary source of energy in the world is the burning of fossil fuel and thus generation of CO2, the environment will benefit from a reduction in the amount of CO2 emitted for every kilowatt of energy saved. Every mW-hr of electricity saved will reduce CO2 emissions by 1 ton. Excessive CO2 emissions are a key reason for the partial destruction of the earth's ozone layer and onset of global warming. Landfills will also benefit from the implementation of LED lighting due to the long useful life of the LED lights. One LED light can last has long as 50 conventional incandescent light bulbs. This is a true savings of waste.
What are the socket sizes used for traditional home lighting?
B22/E27: A conventional pear shaped incandescent bulb uses an B22/E27 socket base. Traditional indoor table lamps, ceiling fixtures, and bathroom fixtures use the B22/E27 socket type. Recessed lighting fixtures typically found in the home and offices also use the E27 socket type; however bulbs for recessed lighting are typically described as PAR20, PAR30, and PAR38. Outdoor lights and some porch lights also use the E27 base.
E14: Most chandelier fixtures in the UK require use the E14 socket base. The diameter of this socket is 14 mm.
GU10: The GU10 lamp is normally used for small track lights that have traditionally used 25W/30W/40W/50W halogen lamps. The pin has a head on the end.
MR16: The MR16 base is also called the GU5.3.The pins are straight. MR16 bulbs are normally used for low voltage (12v) applications.
What type of voltage and current do LED lights require to operate?
Conventional incandescent lamps are made to operate on standard mains power. Discrete 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.Only LED lamps designed to be used with dimmers should be. Only install an LED bulb into a dimmer controlled circuit with a properly designed LED lamp. Fluorescent Tube lamps operate with a specific ballast. To install a T8 LED tube replacement, the fluorescent ballast fixture must be removed or bypassed to provide the standard direct connection of the power to the T8 LED tube.
Are LED bulbs Dimmable?
Yes, some bulbs are dimmable. The majority of LED bulbs are not dimmable, be careful when choosing. LED components operate on DC current typically at 350 mA. Therefore every LED bulb contains a LED driver to convert the AC power to DC power. All our LED dimmable bulbs are designed to be used with standard triac dimmers. Therefore only install bulbs labelled as "Dimmable" in lighting circuits that contain dimmers. Kaijie Lighting brand dimmable LED's are compatible with the standard triac light dimmers. If a non-dimmable bulb is installed into a dimmable circuit, the bulb may burnout, flicker, or damage the dimmer. KAIJIE LIGHTING is not responsible for misuse of LED bulbs and specifically is not responsible for non-dimmable bulbs operated with a dimmer.
What is the colour of light LED's emit?
White light LED's can be manufactured in a range of white colours. White light is measured on the colour temperature scale in degrees Kelvin. White LED's are typically grouped into 3 categories:
Warm White: Typically 2700-3500K. This most closely matches the colour of incandescent light and is the colour of white light most used in the home to create a warm atmosphere. It has an underlying tone of yellow/orange.
Natural White: Typically 4000-5000K. This colour of light is brighter white and does not have a yellow component feeling. Natural white light is typically used for office, retail, basement, or workshop lighting environments. A traditional fluorescent tube light normally emits light in this range. Also metal halide lamps normally are within this range.
Cool White: Typically 6000-8000K. This colour of white light tends to have a bluish tone. Lights in this category are typically used in manufacturing and high brightness environments.
