Would you like to save money and improve the environment? Then choosing LED is an simple choice to make. LED lamps are easy to install into existing sockets and you can begin to enjoy significant savings immediately.
LED is highly energy efficient – Less heat, more light, lower cost
Use less electricity for the same light output – 85% less electricity when compared to conventional lighting and around 18% less electricity compared to CFL. Worldwide, around 20% of electricity is consumed in lighting. LED can make a big impact on your energy use. Savings really ratchet up in areas such as security, where lights are left on for longer periods. The average EU household has 24 lamp points and there is an LED alternative for nearly all of them.
LED lamps last much longer – Saving even more
Typically LED lamps have a lifetime of 25,000 hours – that is over 22 years if used for 3 hours per day. Plus, with no filament LED lamps are more robust. This will result in you saving money on replacement lamps and building maintenance. Conventional bulbs last around 1,000-2,000 hours (1-2 years) and CFL around 6,000 -15,000 hours (6 to 13 years).
LED is Instant ON – No waiting for light
LED lamps switch ON and OFF instantly and are flicker free – There is no warm up time unlike many CFLs
LED is Mercury free – Unlike CFL
A small amount of Mercury is used in CFL bulbs. Any reduction in the use of Mercury will benefit the environment.
LED lamps look the same as “traditional” lightbulbs
You may have seen early “Generation 1” LED lamps that looked more like an alien spaceship than a lightbulb, however, there have been massive advances in LED design so that now LED lamps look nearly identical to the filament and halogen bulbs that you want to replace.
LED gets the green light – More light with much less energy
Over the lifetime of an LED product, less electricity and replacement products are used; saving even more energy in transportation, packaging and maintenance when compared to conventional lamps. All this adds up to lower CO2 emissions, a win-win for you and the environment. As LED lamps are very efficient, they are the perfect product to compliment renewable energy sources such as solar panels or wind power.
LEDs run cooler and can be safer
LED lamps run much cooler than traditional halogen lamps and can be less of a hazard (please consult a qualified electrician for fire safety regulations in your area). Halogen lamps are an inefficient way to heat a space. Using LED will allow a heating or air-conditioning system to run more effectively. When lamps run cooler they minimise the deterioration to light fittings, shades and decoration which can occur with hot lamps – so you light fittings will last longer.
LED is fun
The range of LED products is increasing and products like LED strips that can change colour and brightness make it easier to produce light effects almost anywhere.
LED is the future – and it’s bright
Millions of dollars are being spent on research and development to make LED products even more efficient for the future. The low power and weight features of LED products make it ideal for new types of lighting such as LED strips, downlights and luminaires that are available now. LED products are also being integrated into control systems that can be remotely controlled by smartphones and tablets.
How long will an LED lamp last?
The lifetime of a LED lamp is defined in hours. As with all types of lamp, the light output very slowly fades over time. LED lamps do not generally burnout they will still perform after their rated hours e.g 25,000 hours.
The lifetime is the figure stated when the light output is predicted to drop by a significant amount of the original light output where you may consider a replacement, this is partly due the the slow aging of the parts of the lamps such as refractors and other components. External factors such as heat, humidity, switching cycles and power supply will affect the lifetime of an LED lamp.
The table below gives an indication and comparison with filament and CFL lamps on how many years a LED lamp rated at 25,000 hours will operate.
As you can see a LED lamp will last over 22 years (at 3 hours per day) against a filament lamp of less than a year and a CFL of just over 9 years.
The longer life of LED means less time spent on lamp changes (important for hard-to-get-at areas) . Also it’s great for the environment with less lamps, packaging and transport energy being used.
What are Lumens?
In simple terms, Lumens (denoted by lm) are a measure
of the total amount of visible light (to the human eye) from a lamp or light source. The higher the lumen rating the “brighter” the lamp will appear.
We have all bought 50W or 60W conventional bulbs or spotlights in the past expecting a certain level of brightness. This incorrectly linked power consumption (Watts) to light output.
How many lumens do I need?
There is no firm answer – it will depend on a number of factors including; room size and shape, height of ceilings, colour scheme, type of lamps & fitting, task areas and needs of the user.
As a basic guide above are the lumens required per Sq M (10.76 sq ft) for different room settings. In many cases a mixture of general and task lighting will be required.
Warm White or Cold White?
With LED lighting, especially spotlights you may have the option to choose the “light colour”, known as ” (Correlated) Colour Temperature (CCT) “. Two examples are “Warm White” and “Cool White”. There are no rules – the choice is about personal preference and use. CCT is expressed in Kelvin (K).
A Warm White Integral LED lamp will provide a traditional yellowish colour light, similar to conventional bulbs. This is the most popular choice. (2700-3000K)
A Cool White Integral LED lamp will provide a modern, clean, bright light, that is slightly blue in colour.(4000-5000K).
What are the benefits of replacing your ordinary bulbs with the LED?
There are many benefits. Here is a list of a few:
a. An immediate reduction in your electricity bill.
b. Less heat. LED fixtures are extremely efficient converting electricity into light.
c. LED Bulbs last a very long time, from 30,000 to 200,000 hours.
d. They are virtually indestructible.
e. They do not contain mercury or other hazardous materials
f. Highly recyclable – with no hazardous parts, you can easily reclaim most of the parts in an environmentally safe way.
Can LED bulbs be used with dimmer controls?
Yes and No.
First, not all LEDs are dimmable. The driver must be designed to allow dimming. Secondly, you must purchase the right type of dimmer. Most retail stores now carry dimmers specifically designed for LED bulbs. Please note, if you purchase a non-dimmable LED bulb and try to dim it, it will cause the bulb to fail and also void the warranty.
Some of our industrial and commercial LED fixtures (high bays, floods, area lighting, retrofits) work with a 0-10V dimming system. 0-10V dimming requires special wiring and a special type of dimmer.
Do they contain any hazardous or heavy metals like Mercury?
No, LED bulbs do not contain mercury or any other hazardous metals or chemicals. CFL’s and fluorescents do contain a very small amount of mercury that needs to be disposed of correctly. So when your LED bulb eventually stops to work, you don’t have to worry about costly or special disposal procedures.
What is CRI?
CRI is Color Rendering Index. It is a measurement of the quality of light. Where as lumens is a measurement of the quantity of light, CRI is the measurement of quality. It is a scale between 0 and 100. 0 is bad, 100 is great. LED’s typically are in the 70-95 range. The higher the CRI, the more expensive the LED chip, and therefore the more expensive the product itself.
