Electricity costs are soaring

With efficient LED lighting and electricity at 12-15p per kWh it hardly mattered if people left the lights on.

That’s no longer the case. Electricity is up to 30p per kWh and rising.

Lighting controls are a great way to get the cost of lighting under control.

  • If nobody is there – switch them off
  • If there is plenty of daylight – dim them down

Simple solutions, like adding a sensor to a light fitting can save 50-75% of your lighting electricity costs. This is great for corridors, toilets, and warehouses.

We need to improve the office environment

After COVID many employers are struggling to get staff back into the office. Poor lighting can be another thing to put people off returning.

Dull rows of 600 x 600 panels, all pumping out the same 4000K and delivering 500 lux from dawn to dusk are not going to entice anyone to work. We need to do better.

At NVC we have a range of solutions that can deliver light that changes through the day.

  • Different scenes for different tasks
  • Manual control so people can choose their own lighting
  • Lighting that mimics the natural dawn/noon/dusk circadian pattern to reinforce our body clock and support our mental health

We still need to get to net-zero

CO₂ reduction is still an imperative for all businesses. Lighting controls are a more certain way to achieve CO₂ reductions than any internal memos or committee meetings. The less CO₂ a business is responsible for, the less it has to pay for carbon offsets to achieve net-zero – so lighting controls deliver a double win. Lower electricity bills AND less CO₂ to offset.

NVC Lighting is now carbon neutral and our lighting controls can help you achieve the same.

One size does not fit all.

A warehouse, an office, a care home, a school and a multi-storey carpark have very different requirements. However, the reasons to use lighting controls are usually the same, and fall into three main areas:

Reducing electricity consumption

The cost of electricity has never been higher, and even if it falls soon, it is likely to remain volatile. Lighting controls offer an opportunity to reduce our power consumption by

  • Switching the lights off when they are not needed
  • Dimming them down if there is a substantial level of natural light available
  • Giving users the option to dim their own lights rather than having an entire office, for example, lit to a high level just to cater for a few people who need it.

Creating a better working, living, and learning environment

“Wellness” is mainstream. Achieving 500 lux at the working plane is taken for granted – lighting suppliers, building service engineers, landlords and tenants have been doing that for years – but it has delivered dull uniformity that does nothing to raise the spirits, encourage creativity or nurture our mental health.

We have lighting controls that meet these needs:

  • Scene-setting - so light levels can be adjusted to suit different activities
  • End-user controls – so people and teams can control their own lighting rather than be subjected to an arbitrary level recommended in EN12464 or a CIBSE guide
  • Circadian lighting, that subtly changes through the day in both intensity and colour temperature (CCT) to mimic the natural changes taking place outside.

Reducing the cost of achieving net-zero CO emissions

Whatever happens to electricity costs, we still need to drive consumption down, and the CO₂ for which every business remains responsible still needs to be offset – and that costs money. In fact, the cost of offsetting is expected to rise as the easier offsetting projects are implemented leaving only more expensive offsetting options available.

Lighting controls don’t just save electricity, they are also driving down the tonnage of CO₂ that a business needs to offset.

We have four levels of lighting control solutions available. By offering four different starting points we can provide the solution that is most suitable for your project.

Level 1 One sensor per fitting

Adding a sensor in, or on, a light fitting is the simplest form of control. Most Level 1 solutions provide simple on/off control using either microwave (MW) or passive infrared (PIR) technology. This is a suitable approach for many small projects.

Adding a sensor to the end of a batten





Adding a sensor to the end of a
batten, or under the cover of a
bulkhead, is one of the simplest
and most cost-effective ways to
reduce energy consumption.




Level 2 Master/servant

In a master/servant installation, one fitting has a sensor installed (the Master) and a group of other fittings (the Servants) are wired to it. This approach is widely used in corridors in and warehouses with long racking aisles. Dimming in response to natural light, also known as daylight harvesting, can often be included in a level 2 solution.

Lighting Controls - MASTER SERVANT

A sensor on one fitting in a warehouse aisle


A sensor on one fitting in a
warehouse aisle, or a care home
corridor, can control the other
fittings around it. This is a cost-effective
and user-friendly approach.



Level 3 Simple wireless controls

This is a great solution for classrooms and small groups of offices and meeting rooms. It provides presence/absence detection, daylight harvesting, end-user override and scene setting. Because the components of the solution all communicate wirelessly it is very suitable for retrofit and is simple to install.


Yale range daylight harvesting



YALE is a popular choice for classrooms
and school corridors. It can be controlled
so that it dims automatically if natural
light levels increase, or it could be
manually dimmed for slide shows and
video displays.



Level 4 Wired DALI

This is where addressable emergency lighting test can come together with lighting control in one integrated solution.

Lighting Controls - WIRED DALI

We have four DALI products:

Addressable emergency test only:

  • LightBox Solo. This provides addressable emergency lighting test only for installations up to 128 emergency fittings.

LightBox Solo. This provides addressable emergency lighting

  • LightBox Emergency. Similar to LightBox Solo, but for larger sites up to 1,280 emergency fittings.

Lightbox Emergency control panel

The recent focus on emergency lighting (following the Grenfell Tower enquiry) has made these two solutions (above) very popular. They are easy to install and provide an almost instant upgrade to the integrity of the emergency lighting test regime in any building.


Combined lighting control & addressable emergency test:

  • LightBox Express. Combined lighting control (sensors, daylight harvesting, scene setting, end-user control, circadian effects etc) and addressable emergency lighting test. Up to 128 light fittings, but up to 10 x 128 can be linked together if required.

•	LightBox Express Combined lighting control sensors

  • LightBox. Combined lighting controls and addressable test, but scalable up to almost any size and including a graphical user interface and a head-end PC for easy addressing and identification of fittings. This is the solution for large projects and complex estates.
