Advantages of LED lighting technology

LED (Light Emitting Diodes) lights are up to 80% more efficient than legacy lighting such as fluorescent and incandescent lights.

What are the advantages of LED lighting?

There is far less energy wastage with LED lighting which convert 45% of their energy into light. Compared to legacy lighting such as old GLS lamps and Fluorescent lights which converts around 95% of the energy they produce into heat and only 5% into light.

This demonstrates that LED’s require less power than legacy lighting. Typically a 72 watt fluorescent can be replaced by a 26 watt LED to give the same level of light. LED lighting is far more efficient and results in less energy usage which reduces the demand from power plants and decreases greenhouse gas emissions.

LED lighting consumes low amounts of power, up to 90% less than legacy lighting like GLS incandescent. This gives LED lights a substantially higher luminous efficacy rating.

Luminous efficacy is a measurement that indicates how well a light source emits visible light using a given amount of power.

LEDs have a lifespan of up to 100,000 hours (depending upon the quality of the lamp or luminaire) as opposed to 1,000 hours typical of incandescent bulbs. So a good quality LED light can last over 7 years of constant use before needing a replacement. The long lifetime of LEDs will drastically reduce maintenance costs and lower long-term operating costs compared to traditional lights.

Safety may be the most significant benefit of LED lighting. LED lamps emit almost no heat while incandescent bulbs convert more than 90% of the total energy used to power them directly into heat. Traditional lamps and light sources have surface temperatures that can easily reach well over 150°C.

LED lighting substantially reduces the potential for safety dangers, such as overheating, burns and fires.

Their small size makes LEDs incredibly adaptable to an infinite number of lighting requirements from commercial, industrial to residential mood lighting applications.

As well as the white options, LED lighting is available in a variety of base colours, such as red, blue, and green. These can be mixed together to produce large numbers of colour options.

LEDs are made of non-toxic materials, unlike legacy lighting solutions that use mercury which may pose a danger to the environment. LED is recyclable (via the international WEEE scheme) and also considered “green” or earth-friendly.

There are three relevant measures that relate to the quality of lighting: CRI (Colour Rendering Index), CCT (Correlated Colour Temperature) and Lumen output.

High CRI is generally a desirable characteristic (depending on the required application). LED’s have a high CRI rating (particularly when compared with SON or SOX discharge lighting).  CRI is a measurement of a light’s ability to reveal the actual colour of objects as compared to an ideal light source (natural light). 

CCT or Correlated Colour Temperature is a method of describing the characteristics of visible light. LED’s are available in a variety of options for example: ‘warm’ – a yellowish colour similar to Tungsten lamps or ‘cool’ – white light similar to most fluorescent lamps.

The Lumen output figures are a measure that describes the amount of light being emitted from the lamp or luminaire.

LED lights can be placed and combined in an infinite number of ways to produce effective, efficient, controllable illumination. The colour, shade, brightness and distribution of light can be electronically controlled. This makes LED lighting an ideal solution for almost all lighting applications, from technical lighting issues to soothing, uplifting or energising mood lighting.

The fact that LED’s have negligible UV emissions and that they produce very little infra-red light makes them ideal for use in storage facilities and warehouses as they won’t degrade stored materials by either UV or heat. Libraries and museums also greatly benefit as LED lighting can be used to illuminate areas and artefacts without causing damage. 

LED lighting has the capability to work in very low temperatures. Their typical temperature operating range is -20° to 40°C, making them suitable for most indoor and outdoor applications, including in cold store or freezer areas.

LED lights are bright instantly.  They can also be turned off and on as many times as necessary without affecting their performance, even over the long term. Halogen lights or low-energy bulbs usually take a few minutes to achieve maximum output, and turning them off and on reduces their lifespan.


Earlmann lighting has helped all kinds of organisations light their premises more efficiently, from the public sector, local authorities to blue-chip and SME businesses.

“We are delighted with the creative aesthetic look of the lights in the atrium area. Earlsmann Lighting provided a solution to our brief that not only provides interest but also performs the function of lighting the area to the correct standard.” Basildon Council
“The benefits from upgrading the lighting scheme were evident straight away, our power consumption for lighting reduced from 7kW to 2kW per hour. A cost saving of this significance as enables us to quickly payback the initial capital outlay in a reasonable time frame.” Sovrin logo

3 Step Process

Earlsmann lighting has an easy 3 step process that reviews the current lighting scheme, addresses the required upgrade and supplies and installs the right solution with minimal disruption to your day-to-day operations.

Call 01884 259917  to speak to one of our lighting specialists or email:

FREE Audit | Site Survey

The initial audit is conducted via telephone to identify the client’s requirements and assess the current lighting scheme.
A site surveys* enables one of our lighting experts to physically assess the environment, highlight deficiencies and establish the correct light levels required.

*Available to eligible companies

Design | Specification

This enables us to create CAD models and utilise specialist lighting software to design a lighting scheme that provides the correct light levels and adheres to lighting standards. 

Energy-saving calculations are provided and ROI (Return on Investment) demonstrated.

Supply | Installation

An installation plan is devised to ensure minimal disruption to your day-to-day operations. We assign an account manager to project manage and oversee the entire process.
