LED Lighting with Envantage

Reduce lighting energy use by up to 80% with LEDs

A comprehensive lighting audit can identify opportunities for deploying efficient lamp technologies such as LEDs, which can result in savings of up to 80% compared with traditional lamp technology.

Lighting accounts for a significant proportion of electricity consumed in many businesses. It has been identified by the Carbon Trust as one of the most common ways in which companies can realise energy and cost savings.

In commercial buildings, lighting can account for up to 30% of total electricity usage, whilst in industrial buildings the percentage is typically 5% – 10%.

Energy efficient lighting can therefore yield substantial cost savings.


Invest in LEDs With Envantage

Envantage have extensive experience in providing LED lighting solutions for reducing energy consumption, lowering carbon footprints, and delivering cost savings for large scale public areas, retail spaces, industrial units, and commercial offices.

Returns on investment vary depending on lighting utilisation and the current technology in use, but Envantage have found that payback periods of between 1 and 3 years is typical.

We ensure that the replacement LED lighting we recommend is specifically tailored for the end use.

We only work with lighting manufacturers that we trust, have a proven track record, and supply quality products with excellent warranties.

We have recently installed LED lighting at a frozen food distributor in their chilled and frozen stores, with plans to roll out across the rest of their facility. Not only has the LED lighting saved them a significant amount of energy and money since its installation, but has also improved the lighting conditions to the point where staff are both happier and safer due to the improved visibility.

If you have any questions about your lighting and the installation of LEDs, please call Envantage on 0800 054 2577 or email savings@envantage.co.uk. We will advise you on the best course of action to realise significant energy and cost savings.


LED Technology

LED lighting technology has advanced significantly in the past few years. Lifetimes of 50,000 hours are now common, with extended warranties of up to five years available on many commercial and industrial modules when purchased from reputable suppliers.

The energy consumption of LED modules is a fraction of traditional lamp technology (such as fluorescent, sodium, and metal halide). Below are some examples of recommended LED replacements for a variety of common light lamps/fittings.

(Note that this is not a comprehensive list of possible LED replacement lamps).

Current Lighting LED Lighting
Technology Fitting Type Fitting Consumption (W)* LED Replacement Consumption (W) Energy Saving (W) Energy Saving (%)
Metal Halide / Sodium 250W High Bay 275 100 175 64
400W High bay 450 150 300 67
Low Frequency Fluorescent Tubes (T8) 6’ Tube x2 Fitting 168 60 108 64
4’ Tube x 4 Ceiling Panel 184 68 116 63
Halogen Spot light 50 5 45 90

* The fitting consumption (W) accounts for the lamp ballast and is therefore higher than the lamp W rating alone. For fittings with multiple lamps, the fitting consumption (W) figure accounts for all lamps and ballast(s).



LED lights offer several other benefits over traditional lighting technologies due to the fact that they can be instantly switched on and off and are 100% dimmable.

This allows for effective control of lighting using occupancy and/or daylight sensors, which can realise significant additional energy savings of between 25% – 50%.

Occupancy sensors
LED lights allow for instant on/off switching without risking damage to the lamp or fixing (as with sodium and metal halide, and to some extent fluorescent lamps). This means that they can be integrated with occupancy sensor technology to automatically switch off lighting when rooms are unused.

This is particularly effective in offices with low or partial occupancy, corridors, storage rooms, and warehousing.

Occupancy timers can be tuned to specific situations to ensure that lights switching on and off does not cause irritation, or risk the safety of staff.

Daylight sensors
Daylight sensors can also be combined with LED lighting to realise further energy and cost savings by utilising natural daylight in offices, warehouses and factories to reduce the requirement for artificial lighting.

Many factories and warehouses have transparent roof panels, but the current light fittings (usually metal halide or sodium lamps) cannot be dimmed or switched on and off quickly to take advantage of this free natural source of light. Therefore, the lighting is usually left on all the time.

Daylight sensors utilise lux meters to dim LED lighting in real time such that the overall light levels remain the same, regardless of the amount of incoming natural light. This can mean that on particularly bright days lighting is automatically switched off completely.
