Why LED?

Would you love to save money and improve the environment? Then choosing LED is an easy choice to make. LED lamps are simple to install into existing sockets and you can start to appreciate great savings instantly.

LED is extremely energy efficient – Less heat, increased light, lower cost

Using less electricity for the identical light amount – 85% less electricity when compared to traditional lighting and about 18% less electricity compared to CFL. Globally, approximately 20% of electricity is used in lighting. LED can make a huge impact on your energy usage. Savings really soar in areas such as security, where lights are used for greater periods of time. An average EU home has 24 lamp points and there are LED alternatives for almost each of them. Businesses can make large savings whilst being more eco-friendly.

 

Energy savings made by using LED against other types of lamp

Great for Business

For business and commercial use – changing to LED offers great financial benefits. This is for numerous reasons, such as;

1. Cheaper energy prices – We have assisted businesses in saving many thousands of pounds per year – every year. With the price of LED decreasing, you could see the benefits within a couple of months for lamps to around 12-36 months for LED panels.

 

2. Cheap maintenance and cleaning costs – No more lamp or tube changes – items such as LED panels are straightforward to clean in comparison with fluorescent tube panels. For high ceilings, the requirement for specialist machinery like cherry pickers is also decreased.

 

3. Increased sales? -When improving badly lit areas with LED; we have received feedback from clients who have seen a better atmosphere within offices among employees. Plus, reports from wholesalers and retailers have shown increased sales figures as their product is well lit and customers are spending more time in the store.

 

4. An excellent return – LED gives a high return, for instance, an LED GU10 costing about £3.50 will save over £6.00 per year in energy expenses. ( a 6-month payback and a 195% return based on 3hrs per day and 14p KWh) . A 600 X 600 LED panel retailing at around £80 will save £28.00 per year in energy with a return of 36% (12hrs per day and 14p KWh).

 

LED lamps last longer – Saving even further

Normally LED lamps have a lifetime of 25,000 hours – which is beyond 22 years if only used for 3 hours per day. Plus, with no filament LED lamps are extremely strong. This will mean you will conserve money on new lamps and building maintenance. In comparison conventional bulbs only last around 1,000-2,000 hours (1 or 2 years) and CFL about 6,000 – 15,000 hours (6 to 13 years). The price of LED has fallen over the last several years leading to a considerable reduction of the payback period to just a couple of months for most lamps.

 

Why use 400 Watts in one room? substitute with LED and only use 52 Watts – Save now!

The days when a room was lit with just a single 60W lamp are a thing of the past. In living rooms, bedrooms and kitchens – they have been substituted with 8 or more spotlights instead. Each spotlight could be 35W or 50W (Halogen) – reaching a combined power usage of up to 400W. However with retrofit LED lamps, the energy usage is reduced to just 52W (6.5W per lamp), for the equivalent amount of light. With energy costs seemingly only increasing – it does make sense to change to LED.

The greatest savings are noticed when LED substitutes Halogen or conventional lighting.

If we use a common example of eight 50W GU10 Halogen spotlights in a kitchen – Retrofit GU10 LED lamps can be fitted in a matter of minutes. To see our 50W GU10 equivalent range CLICK HERE!

LEDs save money in a few ways:

1. You will save each year based on lower energy usage per lamp

2. As LED lamps can last above 20 years, you will save even further
by using fewer lamps

The table beneath examines the difference between a 6.5W LED with a 50W Halogen – with the same light output.

Payback can be accomplished in 6 months to 36 months (depending on product and price)

Calculated savings, based on 0.14p/kWh

 

LED is Instant ON – No waiting for light

LED lamps turn On/Off with no flickering, which wasn’t the case several traditional fluorescent lamps

 

LED is Mercury free – Unlike CFL

A little amount of Mercury is used in CFL bulbs. Any decrease in the use of Mercury will help the environment.

 

LED lamps look like “traditional” light bulbs

You might have seen initial “Generation 1” LED lamps that seemed more like an alien spaceship than a lightbulb, however, there have been huge improvements in LED design so that now LED lamps look nearly identical to the filament and halogen bulbs that you want to change.

 

LED receives the green light – Extra light with significantly less energy

Over the life of an LED product, fewer electricity and replacement products are needed; saving further energy in transportation, packaging and maintenance when compared to traditional lamps. this combined produces lower CO2 emissions, which is a huge win for not only you but the environment too. LED lamps are extremely efficient, so are the perfect product to complement renewable energy sources such as solar panels or wind power.

 

LEDs run cooler so can be safer

LED lamps run considerably cooler than traditional halogen lamps and therefore can be less of a hazard (please consult a qualified electrician for fire safety regulations in your area). Halogen lamps are an inefficient method to heat a space. Using LED will enable a heating or air-conditioning system to operate more effectively. If lamps operate cooler they decrease the deterioration to light fittings, shades and decoration which can happen with hot lamps. Hence your light fittings will last longer.

 

LED attracts fewer insects

There is sufficient evidence to suggest that LED products entice fewer insects, meaning less maintenance and cleaning.

 

LED is fun

The collection of LED outputs is growing with products such as LED strips that can adjust the colour and the brightness, make it simpler to create light effects nearly anywhere.

 

LED is the future – and it’s bright

Millions of dollars are being allocated to study and development to manufacturing LED products that are yet more efficient for the future. The low power and weight traits of LED products make it perfect for new varieties of lighting such as LED strips, downlights and luminaires that are possible now. LED products are further being combined into control systems that can be remotely managed by smartphones and tablets.

With decreasing prices of LED products, long-term increases in energy costs tied to improving the efficiency of LED. With more light for each unit of energy; the reasons to change to LED now is pretty compelling as payback times become smaller.

What is a lumen?

Think of lumens as a “modern” way of identifying how bright a light is. Lumens = Light Output.

In simple terms, Lumens (denoted by lm) are a measure of the total value of noticeable light (to the human eye) from a lamp or light source. The greater the lumen number the “brighter” the light will look.

We have all purchased 50W or 60W conventional bulbs or spotlights in the past expecting a particular level of brightness. This wrongly linked power consumption (Watts) to light output.

More light, less energy (Watts) with LED

Using low energy LED lights, a greater light output can be delivered with much less power usage. For instance, a 6.5W LED light will provide a similar light output to a 50W Halogen bulb. That’s 87% less energy for the identical light output! While using LED extra energy is converted into light instead of heat. While technology advances, extra lumens will be generated using even fewer Watts – i.e. increased lumens per Watt. Therefore, as a result, using Watts as a guide to brightness is no longer of importance.

Lumens – Conventional vs LED lights

To produce a similar light production of a 60W standard bulb you will require an LED lamp with around 800 – 850 lumens. Each LED light happens to have the lumen rating distinctly indicated on the packaging and on the base of the light. in addition to this, a conversion guide to the “old wattages” can be found below.

 

Lumens and Helpful Lumens

For non-directional bulbs such as a globe, golf ball or candle shape, the whole lumen output is measured for all directions. With a directional bulb such as GU10 spotlight, the light is emitted in various directions, some of this light (spill light) may not be helpful but it is included in the total lumen rating.

To make comparisons fairer and simpler the EU has recently started a “useful lumens” rating. This is a measurement of useful light emitted in a standardized 90-degree cone. The “useful lumen” rating is usually lower than the whole lumen output but has more significance to a spotlight bulb where useful light is in a forward-focused direction.

How many lumens do I require?

There is no specific answer – it will depend on multiple factors including; room size and shape, the height of ceilings, colour scheme, type of lamps & fitting, task areas and requirements of the user.

As a primary guide; following are the lumens needed per Sq M (10.76 sq ft) for various room settings. In several cases, a blend of general and task lighting will be needed.
