Is it time to switch-on to LEDs....?

LED lighting is becoming increasingly popular - for good reason. It’s hard to ignore the financial and environmental advantages that can be gained when using LEDs in place of traditional incandescent, fluorescent, or even the more recent CFL bulbs:

• LEDs are more energy-efficient as they do not scatter lighting like incandescent and compact fluorescent lights and the bulbs are strong and sturdy, as well as compact.

• Products using LEDs were originally quite costly. Prices have reduced considerably in recent years
• LEDs typically last considerably longer compared to standard incandescent bulbs
• They are much less prone to breaking
• They are sufficiently small in order to suit restricted spaces
• They contain absolutely no mercury
• They generate minimal heat
• Switching on and off will not reduce lifespan
• Energy efficient models are now readily available


Minimising Electricity Costs & Energy Consumption

Quality LED lights present an effective, focused light that is similar to halogen lamps but requiring considerably less electricity. As electricity costs continue to rise, LED downlights become more and more popular both with the financially aware and energy conscious.

Utilization of a 13W LED light produces 68% less CO2 when compared to a typical 40W incandescent bulb whilst, compared with halogens, LED lights just use 15% of the electricity.

The initial cost associated with LED bulbs is deceptive. Even though the initial expense of the LED bulb is higher when compared with the price of an incandescent or CFL bulb, noticeable savings are accumulated even over a relatively short period simply because LED bulbs last longer and use less electricity.

The purchase price of LED lights is cancelled out by savings as high as 80% on energy usage as well as reduced maintenance expenses. It is not necessary for back-up lighting – modern LED lights are quickly at 100 % brightness, each and every time.


The appeal of moving to Led lights is not just economic. Rooms are more comfortable and secure with light bulbs that don’t produce uncomfortable heat. Fluorescent light bulbs produce much greater heat than LEDs and have even been known to catch fire. LED lights tend to be sensitive to neither extreme heat nor cold, whereas fluorescents may possibly not even function at +120° or -10° Fahrenheit.

The increased brightness that can be produced by some LEDs is not welcomed by all but there are now “warmer” variations and some have even been developed to produce light that appears similar to the glow of an incandescent bulb.

Because the "warmer" white LEDs require more yellow phosphor coating compared to the "cooler" white LEDs, the ‘warm white’ variations tend to be less bright than ‘cool white’. There is some variation and colour inconsistency among white LEDs but it is possible to check on the colour “temperature”. A bulb temperature has 4 digits and the bigger the number, the bluer the light will appear. Incandescent light is generally close to 2700K-3000K and it is this that most closely replicates the "warm" look associated with incandescent light.

LED bulbs for instant light
Whenever switching on CFLs or tubular fluorescent bulbs, there is generally a moderate delay or even flickering before full brightness is reached. In contrast LED bulbs, like incandescent bulbs, reach 100 % brightness with no flickering the instant they are switched on. This is a fundamental improvement over CFL bulbs wherever lights are required to be regularly switched on and off.

Replacing LED bulbs
Replacing bulbs is nearly a thing out of the past. A good quality LED light will last up to 15 times longer than a typical halogen downlight and can provide over 20 years of lighting. LEDs also outlast CFLs by tens of thousands of hours and do not need to be treated as a hazardous material when discarded - unlike its mercury containing CFL counterpart.

Dimmable LED lights
Early designs of LED light bulbs had the shortcoming of not being dimmable. On the market now, there are LED bulbs which have been specially designed to function by the use of dimmable switches which are found with a growing number of light fittings.

Switching Existing Halogens

There is no good reason to wait for currently installed lights to burn out - right now is actually a good time to switch halogen downlights to LEDs. Led lights greatly reduce energy use, cut electricity costs and high quality LED lamps can last for 20 years. The newest, energy-efficient LED lights operate at far lower temperature ranges than halogen lamps, are far more durable and use a fraction of the energy. Replacing ‘electricity-eating’, ‘hot-to-touch'’ halogen lighting with energy efficient and cost-effective LEDs immediately reduces ongoing energy bills and substantially improves the carbon footprint.


LED technological innovation has made huge advances over the last few years, with big improvements in high-quality, design and durability. LED lamps are now dimmable, undoubtedly energy efficient, silent, long lived, and available in the market in many light temperatures, both warm and cool. LED bulbs contain no mercury, so there is no problem with their handling or disposal.

There are safeguards to observe such as using products from renowned manufacturers and selecting recommended dimmers. But a well-planned LED installation undoubtedly helps reduce the all-round costs associated with lighting and to achieve an almost zero-maintenance lighting system.
