Guide to Emergency Lighting

Emergency Lighting

Emergency lighting is lighting that works during a power cut, normally using a battery for up to 3 hours of standby power. Emergency lights might be anything from green signage lights to everyday fittings that blend into standard lighting schemes.

Escape & Standby

Emergency lighting falls into one of two categories: escape lighting or standby lighting.
Standby lighting allows work to continue during a power loss, but is not a legal requirement.
Escape lighting is far more critical and subdivided into three categories:

  • Escape route lighting identifies and lights exit routes and enables safe evacuation of a building.
  • Open area (anti-panic) lighting is intended to avoid panic in large spaces (above 60m²) where occupants are likely to gather.
  • High risk task area lighting enables hazardous processes to be closed down so that operators or occupants are not put at needless/further risk.

Emergency lights and their roles are defined by British Standard 5266-1, which is a code of practice for emergency lighting. Up-to-date advice on how to conform to this standard is available for download (PDF) from the ICEL website.

Maintained & Non-Maintained

Emergency lights generally come in maintained or non-maintained forms:

    • A maintained emergency light functions as a regular fitting but stays switched on during a power cut.
    • A non-maintained light is kept switched off and only triggers when the mains supply is lost.

Maintained lights are required in premises where visitors may be unfamiliar with their surroundings (e.g. cinemas, nightclubs, public buildings), while non-maintained lights are used more in private workplaces.

Solar garden lights – ideal for entertaining

Low-priced, easy to install and free to run, solar garden lights are increasing in popularity. Most of them use LED technology, mainly because it needs very little energy. For homes and hospitality settings, creating an attractive night-time garden has never been more affordable or eco-friendly.

Making the most of summertime

Sunny days in Britain are never assured, so when they occur we all seize the opportunity to relax. Maybe we’ll have friends round and enjoy a little something to eat and drink outside. These are moments to savour. As day drifts into night, solar lights keep the social mood going without extra expense. With no mains leads to consider, they can be positioned almost anywhere.

For hoteliers or pub owners, good outdoor lighting is often vital; it provides extra income potential. Extending the summertime mood into evening is easy with the right choice of lighting, and what better choice than one that captures the sun’s energy?

Free Lighting All Year Round

Contrary to common belief, solar panels don’t need direct sunlight in order to work. While it’s true that sunshine makes recharging quicker, solar lights still function in cloudy weather. Many have a manual override switch, which lets you turn lights off when not needed and preserve the battery charge. This also preserves the lifespan of the LEDs or other light source.

Solar Garden Lights – choosing the right products

Garden lighting should suit the style of the property, if a specific style exists. By highlighting features of the garden, you’ll add mood. Lighting darker areas makes a garden more welcoming and creates a greater feeling of space.

A patio or decking area can be bordered by a series of stake lights which can come in kits of 4 and offer great value for money. These are useful for decorative effect or to highlight edges for safety purposes.

A more powerful wall or fence fitting is a good choice for functional outdoor lighting. You might use this to light a table.

For decorating trees, Solar String Lights fit the bill. These sparkling lights create a relaxing mood in any garden. They are also ideal for use around fences, walls, trellises, gazebos and hedges.

LED Outdoors

Aside from being energy efficient and long lasting, LED-based solar lights are resistant to shock and vibration and work flawlessly down to about -20°C. This technology is tougher than rival light forms and perfectly suited to outdoor use.

The light bulb phase out schedule

led bulbs

In 2009, the EU began phasing out of inefficient bulbs in favour of energy-efficient alternatives. The incandescent light bulb has existed for 130 years, but a global need to reduce carbon emissions has made it obsolete. Incandescent bulbs are inefficient because they waste most of their energy creating heat.

New bulbs on the block

The natural successors to the incandescent bulb are CFLs and LED bulbs. These use 60-90% less energy than incandescent lighting and offer a much longer lifespan.

EU phase-out timetable

On 18th March 2009, a timetable was created by EU states outlining the gradual withdrawal of incandescent bulbs from production. Most of the phase-out has taken place, but latter stages of the schedule have been reviewed. The current chronology (May 2016) is as follows:


1st September 2009 Phase-out of clear 100W and above incandescent bulbs.
Non-clear (frosted/pearl) bulbs require an ‘A’ energy rating (effectively meaning they must be CFL or LED).
1st September 2010 Phase-out of 75W clear incandescent bulbs.
1st September 2011 Phase-out of 60W clear incandescent bulbs.
1st September 2012 Phase-out of all remaining clear incandescent bulbs (i.e. 40W and 25W).
24th February 2016 Phase-out of some bulbs previously defined as special purpose, including incandescent rough service bulbs, high/low temperature bulbs and clear glass decorative filament bulbs (tinted glass models still permitted).
1st September 2016 Phase-out of directional mains-voltage halogen bulbs (i.e. GU10, PAR, R-type).
1st September 2018 Phase-out of non-directional halogen bulbs (i.e. candle, GLS, globe, golf ball).

Special-purpose items such as fridge and oven lamps, halogen capsules and linear R7s bulbs are untouched by these bans, as they cannot be adequately replaced by other technologies.
Low voltage halogen lamps (e.g. MR16) remain available in the EU. Unlike 240V equivalents, these can achieve a ‘B’ energy rating by using an IR coating in their design. This ensures the long-term survival of some 12V halogen products.

About energy ratings…

On the 1st September 2013, EU Regulation 874/2012 came into force. Among other things, this introduced A+ and A++ energy classes to cater for LED improvements and deleted defunct F and G classes. From the 1st March 2014, all light fittings entering the market and sold directly to end-users must be labelled with the energy rating of compatible or supplied bulbs (see this article). Fittings installed with non-replaceable light sources must be identified at the point of sale.

LED ceiling lights – our top 10

LED ceiling lights offer many benefits over fluorescent or incandescent alternatives. Aside from their incredible energy-efficiency and lifespan, the compact size of LEDs allows more flexibility in design. LED downlights and ceiling panels often fit into relatively shallow ceiling voids and are a cleaner, more hygienic lighting solution for hospitals, schools and offices. Surface-mounted fittings are also transformed in scope and performance by LED lamps.

At Lyco we keep a watchful eye on lighting innovation and trends and select only the best products for our customers. Here are our top 10 LED ceiling lights:

Ten top LED ceiling lights

Robus LED Fire-Rated Downlight

This downlight offers a 25,000 hour lifespan and a 3-year manufacturer’s guarantee. Fire-rated, this downlight is tested for 90-minute ceilings, allowing crucial evacuation time for upper floors during a fire. Its impressive energy-efficiency easily surpasses the requirements of Part L Building Regulations.

Cavan 8W LED Downlight

Luceco 5W LED Downlight

To perfectly mimic the high quality light of a 50W low-voltage halogen equivalent, this superb downlight uses a special LED module with an 5W Sharp Cob LED chip. Its smooth, crisp light is delivered in a well-controlled beam with extremely low glare.

High Performance Downlight

There are two main differences between these two fittings. The first is longevity – the Sysion has a 50,000 hour lifespan against the 35,000 hours of the Cavan, so it’s ideal for long hours of use. The second is that it can be customised via interchangeable bezels and diffusers.

An improvement over old fluorescent modular ceiling fittings, this panel fits directly into existing ceiling grids. Its 50,000 hour lifespan and energy-efficient performance will significantly reduce maintenance and running costs. This is an ideal fitting for offices, schools, hospitals, and many other environments.

Rondure Pendant

Contemporary fittings like this Rondure pendant are often suspended low over dining tables or desks. This concentrates their light and creates a feeling of intimacy, even in a busy setting. A Decorative Filament Bulb is good for this purpose, as it’s attractive look complements the gold inner perfectly . The Rondure is ideal for restaurants, cafes, bars, or the home.

LED Batten

5ft Vulcan LED Twin Batten

LED lights offer a variety of extra benefits over even the best modern fluorescent tubes. This LED batten not only slices a third off the running costs of a T8 fluorescent tube, but it’s also longer-lasting, tougher, immune to multi-switching, contains no mercury and is suitable for exterior use. Need we say more?

Prodisc LED Flush Fitting with Microwave Motion Sensor

This excellent LED flush fitting automatically switches on when it detects movement. To add to its capabilities it can be wired to a series of slave fittings, so that multiple lights are switched on by the same sensor. With its cool white 5000K output, the Prodisc is ideal as a money-saving LED fitting in environments such as hospitals or schools.

Carina LED Flush with Microwave Sensor

The Carina is a great alternative to the Prodisc. With its IP65 rating, this dust-tight and water-resistant luminaire can be installed almost anywhere, including outdoors or in bathrooms and washrooms. The subtle warm white light of the Carina is ideal for hospitality settings and residential use.

Davida 3-light LED Spotlight

Tate 4-Light Spotlight

Modern spotlight fittings such as the Tate often come with integrated LEDs, so you’ll get years of service before any replacement is required. The Tate is a ceiling bar with fully adjustable light heads. Because the beam of an LED carries no IR heat and little or no UV, it is better suited for lighting sensitive objects such as artworks or textiles.

Acorn LED 3-Light and Track Kit

A track lighting system offers a little more versatility than a ceiling bar, as each light can be freely moved along a length of track as well as being angle-adjustable. The Acorn is ideal for lighting rooms and displays that are often altered. This light kit, which consists of 1-metre length of track and three spotlights, can be extended to a maximum 30 metres using separately available track lengths.

Investing in LED ceiling lights

Whether you’re an architect, interior designer, specifier, or end-user, LED ceiling lights deliver a new level of lighting performance whilst drastically reducing energy bills and the carbon footprint.

LED Lighting guide for dummies

Three decades ago, LEDs were only really known for being the power indicators on electronic devices, as they were too weak to be of much use elsewhere. Today, however, LED is leading the way in the fight to produce increasingly efficient lighting by dramatically reducing energy consumption.

The high-brightness blue LED was introduced in 1993. Twenty times brighter than its green or red predecessors, this was the long-awaited enabler of white LED light. Then, as now, white LED light was produced by blending red, green, and blue light or by using a blue LED with a yellow phosphor. From this point on LED bulbs started their journey to take over the world of lighting.

All very well, but what is an LED?

The real science bit…

A Light Emitting Diode (LED) is a device that allows electrical current to flow in only one direction. It includes two conductive materials, placed in contact with each other. Electricity is applied to the diode so that atoms in one material are excited to a higher energy level. That energy is then released in the form of electrons into the second material, and this release of energy creates light.

How does this differ from traditional lighting?

Traditional incandescent lighting produces light directly by heat. A thin tungsten filament is warmed to about 2500°C by an electric current. Filament bulbs use 90% of their energy in maintaining this extreme temperature.

LED benefits

LED lighting boasts numerous benefits over rival technologies:

  • Energy-efficiency: LED lighting offers energy savings of 80-90% over incandescent or halogen technologies and up to 50% over fluorescent lamps.
  • Longer life: with typical lifespans of up to 50,000 hours, LED lasts 2 or 3 times longer than fluorescent lighting, and up to 50 times longer than incandescent. Maintenance costs are vastly reduced as a result.
  • Instant light: unlike many fluorescent lights, LEDs require no warm-up time to reach full brightness.
  • Eco-friendly: LED lighting has potential to drastically reduce carbon emissions. Around 20% of the world’s electricity is used on lighting. Unlike fluorescent lamps, LEDs contain no mercury, making disposal easier and cleaner. Longer lifespan relieves pressure on landfill sites.
  • Reduced heat output: LED lighting has significant heat dissipation needs. However, unlike filament bulbs, an LED lamp does not project infrared heat in its beam. This increases suitability for lighting heat-sensitive items like artworks or food.
  • Added durability: LEDs are a solid state form of lighting, resistant to vibration and shock. They are less delicate than incandescent or fluorescent lamps, and outperform competing technologies in cold temperatures.

Retrofit LED bulbs such as this 5W GLS look almost identical to traditional bulbs

Can I replace existing lights with LEDs?

Retrofit LED bulbs (ones that fit into existing bulb holders) are suitable in most situations. Close attention should be paid to heat dissipation needs, especially when replacing halogen reflectors in enclosed light fittings (e.g. recessed ceiling light). Advanced heat sink design in modern LED lamps overcomes the reliability problems seen in early models. Manufacturer’s guarantees are often supplied to back this.

A few words about dimming

Take a look at our useful LED v Incandescent infographicLED lighting is excellent for dimming, maintaining energy efficiency at all light levels. However, not all LED lamps or fittings are dimmable. Dimmability is a property of the LED driver, so you need to shop specifically for it. Shop for dimmable LED bulbs

Many modern LED lamps are compatible with old dimmer switches, but the minimum load of a switch (often 60W) is a potential problem if you only want to dim a few lights. It is sometimes easier to install a new dimmer switch, with modern ‘trailing-edge’ dimmers being suitable for LED loads.

Dedicated LED fittings

LED light fittings are increasingly designed with non-replaceable LEDs, mainly due to their long LED lifespan. In this instance, the whole luminaire is replaced at the end of its useful life. One of the advantages is that designers can build light fittings that are fine-tuned for efficiency, with very little light being wasted.

Does the light from an LED reduce over time?

Yes, it’s a process called lumen depreciation, which affects LED and fluorescent lighting. Incandescent bulbs produce the same amount of light throughout their lifespan.

LED lifespan is usually measured to a point where it has lost 30% of original lumen output (known as 70% lumen maintenance, or L70). Lumens are used to measure the total amount of light produced, regardless of direction or beam angle.

Reducing carbon emissions

It is argued by scientists worldwide that we are heading towards potentially disastrous climate change due to excessive carbon emissions. The way we create and use our energy is all part of this equation and regardless of your stance, reducing your carbon footprint is definitely a positive way of doing your bit for the environment. You’ll be saving money at the same time!

A switch to LED – savings in a UK household

The average UK household effectively creates 10 tonnes (10,000 kg) of carbon dioxide per year. Electricity usage accounts for roughly a third of it.

If a household burns 6 x 60W filament bulbs for 4 hours a day, that amounts to 319 kg of carbon emissions a year. The annual energy cost will be around £70.

By comparison, 6 x 10W LED retrofits produce 54 kg of carbon dioxide per year and cost £11.50 in electricity. In one year, you’ve recovered most of the bulb costs and still have years of light ahead.

Since lighting accounts for 15% of the average home’s electricity bill, an LED conversion significantly reduces your carbon footprint.

LED in summary

LED lighting is energy efficient, long-lived, eco-friendly, robust, and all-round cool (except around its heat sink). In addition, it produces little or no UV, is unaffected by frequent switching, is naturally directional for precise control, and it’s compact. LED is the future of lighting.

Shower lights – clear ideas

Many people have a distinct preference for taking either a bath or shower. It’s the rushed lack of luxury that spoils the showering experience for some, but a shrewd choice of shower lights can improve that perception. With the right lighting, a shower needn’t be claustrophobic or uninviting.

Below we look at some of the best ways to use shower lighting, the types of products that are available and offer guidance in terms of any applicable regulations.

Shower lighting ideas

A classic technique used in shower lighting is to position fittings over a rear wall. This provides a greater feeling of space, rather than creating a boxed-in effect with centrally positioned lights. Any light that reflects from a surface is naturally diffused, which has a flattering and restful effect.

Fireguard LED7 dimmable spotlight in whiteFor their remarkable energy efficiency and lifespan, LED fittings such as the Integral 6W LED Downlight offer excellent value for money. Highlighting features of this downlight includes an astonishing 35,000 hour lifespan and 3-year guarantee.

If recessed ceiling lights are not possible, consider wall-mounted outdoor downlights with high IP ratings. Remember that LED lighting is 80-90% more energy efficient than halogen lighting and needs far less maintenance. Halogen lighting has its own merits, including modest initial outlay and superb colour rendering.

Building regulations

In the home

Installation of shower lighting in the home is subject to Part P Building Regulations. An NICEIC ‘Part P factsheet’ is available in PDF form here.


HSE Electricity at Work Regulations apply to workplaces such as hotels or university campuses.

In all instances reference to IEE Wiring Regulations (17th Edition) is required (see below). Note that ‘IET Wiring Regulations’ are the same (the IEE now forms part of the IET).

Bathroom Zones and IP Ratings

Latest IEE Wiring Regulations (17th Edition) divide a bathroom into Zones 0, 1 and 2. Perceived risk of electric shock defines each zone. Areas falling beyond these zones are ‘outside zones’ (the previous Zone 3 no longer exists).

Please see our articles on bathroom zones and IP ratings for precise details.

Shower power

In some countries, the idea of bathing in a pool of stagnating water is odd. A shower is more hygienic, uses less water, takes less time, and often uses less space. A little care taken over warmth and light makes it enjoyable, even, to the extent that some people burst into song!

The Arc floor lamp – overhang gets a new name!

The Arc floor lamp isn’t part of a new range of floor lamps from one of the best known lighting manufacturers on the market. It is in fact what we until recently called an overhang floor lamp – those floor lamps that go up and then lean out, allowing you to specifically place your light where you want it.

What’s in a name

For some reason the popularity of the term ‘overhang’ has diminished and for no more than purely aesthetic reasons people have been drawn to a name which to be honest does sound a little less clumsy. So in all but name nothing has really changed! The same great range of overhanging floor lamps is available, but under a new, arguably improved banner.
