Star Trading LED Light Sources

LED (Light-Emitting Diode) is a modern technology for producing light using electricity. This technology offers several advantages such as::

• Saves energy
LED lamps are the most energy efficient alternative on the consumer market. For the same light output you will save about 85% energy compared to incandescent lamps.

• Longer life
You will save money on lamp purchases and reduced maintenance costs. The long life also means less electronic waste. LED lamps last for many years and are also less sensitive to vibration and external force.

• Lights up instantly

• Withstands cold

• No mercury

• No radiating heat (IR-radiation)

New regulation for lamps

What´s going on?
The EU Ecodesign directive means that old, inefficient light sources such as the incandescent light bulb are phased out and banned. The ban means that you are no longer allowed to manufacture in or import to the EU. Lamps still in stock at manufacturers, shops and individuals can still be sold and used. At the same time, new quality standards and energy labeling is introduced for the replacements.

Why?
The new regulation has been put in place for good reason. On average about 25% of your household electricity consumption is related to lighting. The EU as a whole will, thanks to the new rules, annually save more energy than Denmark consumes today.



Light output is measured in lumen, not Watt

Watt (W) only measures the energy consumption and tells you nothing of how much light a lamp produces. A 40W incandescent lamp and a 7W LED lamp produce about the same amount of light, but the LED lamp uses far less energy to do so.


Lumen (lm) is the unit for luminous flux, i.e. the total amount of light emitted in all directions. Lumen is the most relevant measure for omnidirectional lamps but does not tell you how much energy a light source uses.



Candela (cd) is the unit for luminous intensity and is mostly relevant for directional lamps. If two reflector lamps have the same total luminous flux as measured by lumen, then the lamp with the narrowest beam angle will have the highest light intensity measured in candela



Beam Angle is relevant for directional lamps (reflector lamps) and tells you the width of the light beam.




Kelvin (K) ) measures the colour of the light or “colour temperature”. The lower the Kelvin the warmer the light. Any lamp below 3000K is usually called warm white. An incandescent lamp has a colour temperature of about 2700K.




Colour rendering Index (Ra) ) is a measure of how well the colour of objects lit up by the light source look in comparison to a reference light source. Ra 100 is the highest possible.




Dimmer compatible - lamps can be controlled using many common dimmers. To ensure a good result you should always verify that the lamp and the dimmer are compatible. You can always find an updated list at at our pageTo dim LED.



Reduce the energy consumption – not the light

A lot of light (lm) at low energy consumption (W) means an efficient light source with high luminous efficacy (lm/W). As a measure of the efficacy there are energy classes where A++ is the highest. All lamps in this brochure are at least class A products.

A lot of us are used to thinking of the energy consumption of a light bulb (W) as a measure of its light output. The tables tell you how you in some cases can translate the light output in lumen from an LED lamp to the equivalent wattage of traditional lamps.


Life length and quality

LED lamps, when used properly, will last for many years. They will, however, lose some of the light output over time. The life length stated on the packaging should be seen as kind of average and not a guarantee.

All lamps in this brochure are of course CE marked and meet the safety regulations in the applicable standards.

Recycle all your lamps
When a LED lamp breaks you do not need to take any special actions. LED lamps do not contain any mercury and should therefore not be recycled with fluorescent tubes. They can on the other hand be recycled and should therefore, just like incandescent lamps, be recycled as electronic waste.

LED can be used outdoors
LED lamps are not affected by cold and can therefore be used outdoors in proper fixtures (IP44). On the other hand the life length is reduced if subjected to intense heat and they are therefore not suitable in special applications,e.g. in a sauna.

How to choose your lamp

1. Socket
Choose the right socket to fit you luminaire.

2. Light output
Choose light output as needed. Omnidirectional lamps are chosen by lumen. With directional lamps you can also look at candela and beam angle.

3. Shape and size
In many cases the shape of the lamp is purely a matter of taste, but in some cases a certain shape and size is required in order for the lamp to fit in the fixture or for the lamp shade to attach to the lamp. The height and width of the lamp is stated on the packaging, our webshop and in our brochure.

4. Features
Choose a dimmer compatible lamp if you want to be able to dim it or if the luminaire has a built-in dimmer.

You can choose colour temperature (Kelvin) according to preference. For a warm ambiance select lower Kelvin or for a crisp, clear light select higher Kelvin.

The LED technology also offers new features never available with traditional lamps, e.g. built-in light sensor or colour changing.
