For most of us, the more the world shifts, the more we wish that things could stay the same. But when it comes to technology that yearning for what we’ve always known can sometimes get in the way of innovation when a real game-changing opportunity comes along. Let’s take a look at the fire-rated downlight and consider how we’ve always dealt with that thorny problem.
Light costs money and the more light you want, the more money it is going to cost. This simple statement has driven lighting specification since Edison was a lad and it doesn’t matter that we’re entering a whole new phase of energy efficiency; light still costs money. So when a company needs at least 1000 lux of good quality light for it to do its work effectively, the issue of system cost looms large in the decision-making process.
The arrival of winter is generally greeted with scare stories about how, due to an overstretched National Grid, the cold weather could bring with it power cuts. This year the squeeze on electricity supplies in the UK is less severe than expected due to more coal power on the system, however Greenpeace are not convinced and have issued a call for more households to move to LED lighting.
The last frontier of the LED revolution has been high-power applications such as high-mast area lighting, where fixtures with massive lumen packages are required. It now looks like that last frontier is being well and truly conquered, as organisations switch from discharge technologies. A good example is Heathrow Airport in London, one of the busiest airports in the world. The apron lighting has now been upgraded fom high-pressure sodium to LED.
The shortlist for the 2016 Lux Awards has been announced and this year the list features a whole host of impressive projects and inventive new technology.
Changes to the way the UK Government sets waste-handling targets means that most companies and organisations should now be able to access free lamp recycling. Nigel Harvey, chief of waste lighting compliance scheme Recolight, says the message needs to get out that there is a structured process for taking back end-of-life lighting equipment, and for most firms, it’s cost free. ‘We still come across many end users and facility managers that are being charged to deal with waste,’ says Harvey.
The Value Proposition is a series that takes a look at the continuing developments in lighting technology, for all those seeking to improve the efficiency and performance of their projects.
