LED Lighting – Auckland, New Zealand

LED lighting as we know it today is a relevantly new lighting technology. In the last 10 years, there has been major advancements and LED now gives bright light with huge power savings, are low maintenance and at an affordable cost. Alpha Lighting has a large range of LED lighting options for you to choose from. It is important to know about what you are purchasing, we offer either Integral LED fixtures or fixtures where an LED lamp can be fitted. Integral LED fixtures are where the LED is permanently fixed in place and is non-replaceable/changeable for its life time. Fixtures where an LED lamp can be fitted allow you to choose bulbs with different colour temperatures and beam angles.

LED Lamps will fit into many traditional style lamp holders. It is Important when using LED lamps to replace other technology that you have considered the operating systems 12V or mains voltage? For 12V even when a lamp is designed to be compatible with many different power supplies, there can be issues due to, for example, the variations of differently designed halogen transformers and the way in which they are installed. LED lamps are available in a range of colour temperatures for different applications. LED lamps boast long lamp lives from 20,000 to 30,000 hours which highly reduces maintenance requirements

Basic LED terminology to look out for:

Kelvins colour temperature: this is a term to explain the colour of white light produced by the LED. At the lower end of the scale 2,700 to 3,000K this is a warm colour white more like a candle flame and like the light from the old incandescent lamps we are all used to. 4,000K is more of a pure white light and is slightly brighter. 5,000K through to 8,000K gets progressively more blue in tone like a bright daylight – good for offices but not so relaxing for when sitting at home watching TV.

Lumens: is the quantity/volume of light which comes out from the LED. This volume of light can be intensified or not depending on the design of the LED chip or fixture. The smaller the beam angle the brighter the light beam will appear which is good where high contrast might be required. Whereas a greater beam angle will spread the light further and will be less bright.   

CRI: the “colour rendering index” measures how true colours are seen. An old fashioned incandescent lamp is 100% = CRI 100, which means it will show all the lighted objects colours. Most LED’s available now are from CRI 80 to CRI 95. There is some colour which will not be shown by the light however at this level it is scarcely noticeable to the human eye.

LED Advantages

Efficiency: LEDs emit more lumens per watt than incandescent light bulbs. The efficiency gives savings of 70% to 95% over incandescent technology.

Colour: LEDs can emit light of an intended colour without using the colour filters as traditional lighting methods need.

Instant light: LEDs light up very quickly unlike old magnetic ballasted fluorescent fixtures.

Less heat emitted: In contrast to most light sources, LEDs radiate very little heat in the form of infra red heat that can cause damage to sensitive objects or fabrics. Wasted energy is dispersed as heat backwards through the base of the LED rather than forwards at the object it is lighting.

Lifetime: LEDs can have a relatively long useful life 25,000 to 50,000 hours, though time to complete failure may be longer. The life time of an Incandescent light bulb is 1,000 to 2,000 hours. LEDs are a low maintenance option.
