Newey & Eyre’s Newlec DALI network solution can be used to configure up to 64 ballasts or used as part of a much wider overall lighting strategy, connecting many hundreds of separate DALI systems on different floors of a building for example, forming them into a coherent building lighting control system. ,

According to a recent study a huge 30% of energy consumed by buildings is used inefficiently or unnecessarily. lighting accounting for a the energy used in comm

It is estimated that lighting controls can eliminate 60% or more of the wasted lighting energy in buildings while enhancing occupant comfort and productivity.2


Why, you may ask, aren’t


lighting controls as highly considered then as other green technologies such as, say, the LED? Reasons range froma misconception around the complexity of both installing and using lighting control technologies through to confusio n

around the potential savings and payback on investment. However, this is changing. In the main this can be attributed to revisions to Part L of the Building

gy stringent guidelines regarding the


conservation of energy in both domestic and commercial premises ever seen. Most prevalent, the changes have transformed the way that ligh ting efficiency is calculated; it is no longer based solely on the light fittings but the lighting controls installed as well. This means that lighting controls can no longer be an afterthought but rathermust be included with the initial design of a project to ensure lighting efficiency compliance. Therefore, installers who may have previously been reluctant to embrace the changes by Part L, partly because many premises were specified prio r to April 2014, and also because of the complexity typically involved, can no longer afford to put lighting control on the backburner. The good news, however, is

t really


couldn’t be simpler. This can be found by looking at the newest generation of DALI solutions which offer the ultimate in ease of installation and commissioning when intelligent lighting control is required. For ease of integration the new Newlec DALI occupancy detector, for example, can automatically detect DALI lighting ballasts already in place. The installer then simply wires the Part L compliant DALI luminaires, the Newlec power supply unit and occupancy detector together. A DALI lighting control system can be

Typically many commercial building s already have DALI compliant ballasts in place, which are not used to their full potential, instead being employed on more traditional on-off control systems. As such, for the building owner or occupier, utilising these ballasts for a DALI-controlled system can offer a much more preferable solution to installing an entirely new lighting control system. Programming is simple for both the installer or systems integrator and th e end user. The Newlec DALI Occupancy Detector has default settings for broadcast mode, timing and daylight harvesting with only the single handheld remote control required to both operate and programme the system. The system is designed to make it easy for end users to configure lighting that covers both personal preferences, while being energy efficient. This removes the need for a certified Integrator and, in turn, projoject costs and overheads can be reduce d. The remote can also be used by the installer or systems programme the syst


em, with specific integrator to


installer modes for the discovery of ballasts, programming of luminaires and room timing options for example.


The DALI standard has the potential to make significant energy savings for end- users. The combination of daylight harvesting, presence detection, corridor modes and room timing options hav e delivered savings of up to 80% on energy consumption just from lighting. With energy efficiency very much a global concern, the issue of lighting control and the key role it has to play in aiding the green agenda, is only going to get bigger. As such, it will pay dividends for installers who keep abreast of key solutions such as the Newlec DALI Solution which can help to make


significant energy savings for end-users, while remaining eas y to install an d configure. For those who haven’t already tried DALI then, surely it’s time to come out of the dark and into the light?
