The higher the number, the cooler the light. The standard unit of CCT is the kelvin (K). With standard white LED lighting, these tones range from a warm-yellow to cool-blue white light with several options in between.Ĭollingwood uses the industry-standard Correlated Colour Temperature, or CCT rating, to describe the tones of white light available. This allows you to bring out the best in the design and materials in your room. LEDs make it possible to have a choice of white colours or 'tones'. One lux is equal to one lumen per square metre at a distance of one metre from the light source. Lux is the level of light intensity within a specific area. But do remember that the narrower the beam angle, the more focused, and consequently more intense the illumination.Īnother term you may come across is lux.
As a quick translation, a standard 60-watt incandescent bulb produces about 800 lumens of light whilst a 100-watt incandescent bulb is equivalent to around 1600 lumens. One lumen is the level of light provided by a single candle. Instead, their brightness is measured in lumens. LEDs are enormously energy-efficient so assessing the level of light they emit by the level of energy they use would not be a good indicator. If you’ve been brought up assessing light levels in terms of a lamp's wattage, judging its intensity in lumens may not come naturally.

But by using a combination of the different types you will create an exciting environment that people want to spend time in. It isn’t necessary to include all types of lighting in your design for it to be successful. Outside, lit paths and steps provide low-level guide lighting. Low-level lights in the ground or set low in walls and kickboards provide a soft level of mood lighting and can also act as an effective night light. In the garden spike lights can be used to highlight shrubs. Mid-level uses wall lights, table lamps and lights under cupboards to provide illumination at an intermediate level. High level illuminates features like ceilings, cornices or tall trees. Task lighting provides focused illumination on specific areas where tasks are performed.Īccent lighting provides points of focus, highlighting objects, or simply creating visual interest to add depth in the space.įurthermore, you can place lights at different levels: By layering luminescence from different sources, and at different levels, richness and depth will be added to any space.Īmbient lighting creates general background illumination, replacing natural daylight. Remember that it is the combination of light and shade which is essential to good design. Use LED lights as you would any other source of illumination.

Our marine-grade stainless steel outdoor luminaries are the product of choice in harsh conditions our Pro Downlight range with its 70,000-hour lamp lifespan backed by a 7-year extended warranty is the professionals’ preference and our colour switchable collection makes life simpler for specifiers in commercial applications. Indeed, Collingwood is a leader in integrated LED lighting technology, setting the standards in quality and innovation to which others aspire. Since then we have been responsible for many more ‘firsts’, including sealed for life LED outdoor lights, fully waterproof in-ground LED lights, and the very first mains dimmable LED downlights. The company revolutionised the industry in 2008 producing the first high-performance fire-rated LED downlight.

There are simply no disadvantages, LEDs go from ‘off’ to full illumination instantly they come in different colour temperatures as well as in the full spectrum of colours and you can even buy luminaires that dim to a warmer-looking light for a cosier atmosphere, just like lamps with a filament.Ĭollingwood Lighting has specialised in LED technology since 2002 and has been at the forefront of innovation ever since. LED bulbs use 90% less energy than traditional light sources and have an exceptionally long lifespan, typically lasting three times longer than a fluorescent tube and as much as fifty times longer than an incandescent bulb! LED (short for light-emitting diode) lights have totally transformed illumination in all domestic and commercial applications because they are far, far more efficient than the lighting sources they replace. Why choose LED lighting from Collingwood?
