LED Lighting is the future of lighting, these new eco-friendly light bulbs save both money and energy. A typical bulb lasts around 50 000 hours of continuous operation, that’s over 17 years if used for 8 hours every day! They can also reduce your lighting bill by up to 90%, that’s a saving of up to £300 per year based on the average 3-bed semi detached home.
LED lighting for Indoor and Outdoor Use
There is a selection of direct halogen replacement bulbs like the new GU10 SMDs, MR16, E27 and MR11, simply plug these replacement bulbs straight in to the old fixtures and benefit from huge savings on your electricity bill.
In addition, there are direct replacement bulbs for your existing lamps and old light fixtures, these bulbs feature the same screw in or bayonet cap but benefit from running low level LED lighting saving both energy and money.
LED strip lights are simple to install and are an illuminating addition to a kitchen, bathroom, lounge, hall, cupboard or even the humble garden shed. There are a number of different types of strip lighting available including waterproof strip lighting, non-waterproof strip lighting, pipe strip lighting, and waterproof gel strip lighting. These come in either 2.5 metre or 5 metre rolls. In addition to the LED strip, you will need a 15 watt transformer for each metre of strip lighting. The longest length of strip lights you can run with one transformer is a 5 metre length and this will require an 80 watt transformer.
LED flood lights are designed for outdoor use making a great addition to your outside area and are especially useful as security lighting when combined with a PIR sensor. The floodlights come in a number of different power outputs, depending on the strength of light you require – from 900 through to 7500 lumens.
Choosing an LED Lighting colour - Warm White or Cool White?
When buying LED lighting bulbs for indoor use it is important to choose the correct colour option in order to achieve the right lighting effect. There are two main colour options to choose from known as warm white and cool white. Depending on which you select, these two different colours will create a different atmosphere on your room.
Most people when choosing a bulb for the home or living area will go with a warm white, the warm white gives of a lovely softened natural glow similar to existing halogen bulbs.
Cool white gives a much brighter glow and is great choice for kitchens and bathrooms, however this ultimately is down to preference; the light given off by a cool white bulb is a clear more crisp kind of light.
Dimmable or Non Dimmable LED lighting?
Having a dimmer switch in any of the rooms in you home or studio can help create the desired mood lighting and will help with creating an effective ambience. However before choosing a dimmable bulb you will need to ensure your lighting circuit is dimmer compatible. If you are replacing old halogen bulbs with a GU10 LED SMD this should be fine. However if you are running any 12-volt system you will need to ensure that you have dimmable transformers and a compatible LED trailing edge dimmer switch. To replace the 12 volt halogen system with a new LED light system can be expensive, we would recommend changing the down light fitting to a GU10 this would save you from changing the transformer and switch.
What is an SMD (Surface Mounted Device)?
An SMD or surface mounted device is an LED light, which is connected to or soldered onto a circuit, SMD’s are found on the majority of LED bulbs. LED bulbs have a number of smaller chips, which are on the circuit that create the light. The higher the number of chips the brighter the light or the more lumens it creates. These types of bulbs with SMDs generate a high quality light the same colour as normal household bulbs.
What are lumens?
A lumen is a measurement of how much light is given off from a light source, the power of a light or “luminosity” in simple terms is basically how bright a light is. If the power of a light were not very strong or dim you would say it’s not very luminous. So the higher the Lumen of a bulb, the stronger the light. Basically a lumen is the strength of a single candle from one foot (or 30cm away). So if you have a bulb or lamp that is 100 lumens it would be as strong as 100 candles from one foot away.
Top 10 Benefits of Switching to LED Lighting
- Last for longer – If you have fitted Halogens before you will know that these have a tendency to pop quite often. LED bulbs can last up to 100,000 hours in their lifetime, this is because they don’t have a filament to blow up or burn out.
- They are very energy efficient – They can be up to 90% more efficient than a standard incandescent light bulb, this Is because they have been designed to use 80% of the electricity and the other 20% is lost in heat.
- Incredibly quiet - compared to the old halogens that have been known to make a humming noise
- Perfect for dimming - this is because when they are dimmed they maintain their normal colour, in comparison to the incandescent bulbs that turn yellow when dimmed.
- Safety first - They have the advantage of being safe to use, by only creating 20% heat you will no longer get burnt hands/fingers when changing the bulbs, and no broken glass because of their robust design.
- Incredibly versatile – Come in a number of shapes sizes and designs and can be place just about anywhere in your home, garden, pool, club wherever you want them there is an LED bulb type that will suit.
- Better for the environment – They are 100% recyclable and do not contain any toxic chemical s unlike their incandescent predecessors. Because these eco-friendly lights last longer it can stop the materials and manufacturing costs of up to 25 incandescent bulbs.
- Low voltage – Meaning they use a lot less energy, making them ideal for use outdoors, with this in mind you can easily hook them up to a solar panel.
- Incredibly durable and robust - Due to their build quality and sturdy design. LED lights are resistant to shock vibrations and external impacts.
- Zero ultra violet emissions – When they are lit they give out little or no infrared light, because of this it makes them ideal for lighting up ultra violet sensitive object such as materials in a museum, or art gallery.
How to Change Down Lights (Retro Fit)
The majority of LED lighting bulbs have been designed with ease of use in mind, they are know as retro fit, which basically means there is a direct replacement for you old halogen down lights. Below is a list of replacement bulbs and what kind of fitting they are, the GU10 SMD fitting will require you to twist the bulb anticlockwise to remove it from fitting and the others simply pull out, please note if you are replacing halogens please ensure they are cool/cold and have been turned off for sometime before removing:
- GU10 SMD – 2 Probes
- MR16 – 2 Pins
- G4 LED bulb – 2 Pin
- MR11 LED bulb – 2 Pin
- G9 LED bulb – 2 Pin
How to replace a standard incandescent bulb (Retro Fit)
The bulbs you will usually find in your home are one of 2 types of fitting they will either be screw in or bayonet, the LED bulbs listed below in the image are retro fit meaning they are a direct replacement for the older less efficient bulbs. Below is a list of bulbs and the type of fixture they have to change them simply unscrew your old less efficient light bulb and change to your new eco friendly energy efficient light bulb.
- E27 LED bulb – Larger Screw cap
- B22 LED bulb – Bayonet Cap
- E14 LED Bulb – Small Screw Cap
In the image below you can see examples of the types of bulb fittings and their type number. There are a great deal of different bulb types available for each fitting type and a great deal of different colours, shades, strengths etc.... Most of these can be purchased from your local DIY store or in some cases supermarkets and local homewear stores.
Fitting Replacement LED Ceiling Lights
Ceiling lights are a single fixed unit including the casing that will fit directly into a pre drilled hole. Each LED ceiling light has a transformer built into it to control the amount of current that flows to the bulb. These ceiling lights are usually adjustable as the bulb units are on a swivel so you angle the light into a particular area. You can have as many of these ceiling lights on a circuit as you require which is usually dependent on the size of the room. This particular type of LED lighting comes in a variety of different power outputs and with colour options cool white and warm white available. The fixed units are also come in chrome white and brushed stainless.
If your not sure about fitting these we would strongly recommend calling a professional electrician as some wiring may be required and also dependant on what room they are being installed in e.g. Part P regulations will come into effect if they are to be installed in the Kitchen or Bathroom.
How to set up LED strip lights
When setting up an LED strip light you will require 15 watts of power per meter of strip light the majority of strip lights can be bought in either 2.5 meter or 5 meter lengths. The maximum length of strip you can power is 5 meters, but there is no restriction on how many 5-meter lengths you can use on a compatible transformer.
When setting up a single colour strip you have a positive and negative wiring flex this can connected to the 12-volt transformer, which takes a 240volt mains circuit.
Again as mentioned above you may be required to carry out some wiring and if you do not have the necessary qualifications or certification e.g. Part P then please ensure that you contact a qualified tradesman to do the work for you. A qualified electrical tradesman will also be able to offer you advice on what type of bulb will be best suited for your particular needs and also what products are best in terms of quality, price and reliability.
