Restaurants have large overhead costs to consider like everyone else when balancing the books of their business, and their energy bills are a big priority.
Besides powering kitchen appliances such as cookers and storage facilities, lighting and computing requirements, restaurants are one of the biggest user groups of electricity across the world. In the USA for example, the annual energy bill for the commercial food sector is estimated to be around $10 billion, according to ‘Energy Star’.
To keep running costs down, and reduce the carbon impact on the environment, several chains and sites are making the change to LED lighting.

A well-lit car park is not only safer for the public, but can also improve the look of the space quite dramatically. Poorly designed car park lighting can result in higher energy consumption, bad visibility and higher maintenance costs.

The opening angle (also called angle of aperture or radiation angle) is the extent to which the light of a light source is spread. The opening angle is therefore expressed in terms of degrees. An opening angle is always measured on a light source, and not on the lighting fixture (the appliance in which the light source is installed). With LED lighting the opening angle is often directly expressed on the lighting fixture, since the light source is mostly fixed into the fixture. The opening angle you require mainly depends on the purpose the lighting needs to serve.

Lighting can make a huge difference to the look and feel of houses, theatres, exhibitions, streets and offices. But how much difference do we notice, just by changing lighting. Here are a few examples of before and after shots, showing the significant difference in visibility, colour, vibrancy and atmosphere.

Light is an indispensable environmental input for human beings, above all in controlling the basic functions of the human body. The presence of light, its colour and warmth has physiological and psychological effects on human beings.

Here we look at the importance of good lighting in schools and how it can affect how teachers and students engage in education. Energy efficiency is also important to this sector, where 30% of energy costs are spent on it’s lighting in average.

Having not explored the world of retail lighting in our previous blogs, we feel it is about time we provide you with a little bit of an insight in retail lighting.
Lighting plays a huge part in the world of retail. It may cost a fortune to install and run, but it’s worth the investment. Done badly or with little care lighting can have catastrophic financial effects.

It’s already one year on since the great London 2012 games, so we thought we’d look at some of the inspirational lighting design that helped make the park looks so spectacular.

In a special feature today we will have a look at 3 products which could be classified as novelty lighting as they all heavily take inspiration from everyday objects. However, this isn’t to say they are purely novelty and joke products, in fact they are all good, well designed pieces of sculptural lighting!

Unit of light intensity; It defined the magnitude of an electromagnetic field , in a specified direction. 1 cd is defined as the light intensity emitted by a monochromatic light source with a radiant power of 1/683 W at 555 nm.
The luminous flux describes the total light power emitted by a light source. It is calculated from the spectral radiant power by evaluating this with the spectral brightness sensitivity of the eye.
The illuminance, measured in the units of lux (lx), is the ratio between the luminous flux incident upon an area and the size of that area.
