South Africa has experienced sharp increases in the price of electricity over the last few years.
This trend seems set to continue for the foreseeable future, not only are we experiencing rising costs, but Eskom is constantly pleading with consumers to cut electricity consumption to avoid load shedding.
Although lighting may only make up about 10% of our overall electrical consumption in an average home, the figures can be very different in the commercial environment, reaching as high as 40-50%.
Replacing your old incandescent and halogen lights and bulbs with energy efficient and long lasting LED lighting will not only cut your lighting bill by as much as 80%, but it also offers huge savings in terms of maintenance.
If you are considering installing a back up power supply, generator or inverter, then converting your existing inefficient lighting to LED Lighting will greatly reduce the required load that your standby system needs to cater for, meaning you can install a smaller, less expensive system.
An average 3 bedroom home may have up to 3 KW’s of lighting, by converting this to LED lighting you could easily reduce this load to under 1 KW thereby reducing the possible load your standby system needs to cater for by a massive 2 KW’s, these savings will be even more impressive for a commercial environment.
Beware, in the absence of local standards the South African LED lighting market has been flooded with products of inferior quality that boast “over the top” claims, we strongly recommend the use of reputable brands that have been manufactured to stringent EU standards only.
LED Lighting offered on a Project Basis only, we do not provide one off over the counter sales.
LED Lighting Maturing.
LED Lighting is improving not just in terms of “How Much” light is generated, but also in the quality of the light being emitted.
Earlier LED products were quite poor at generating “realistic” light.
Natural daylight is made up of all seven colours of the spectrum, whereas LED’s are naturally blue and make use of just the three basic colours, RGB, or various chemicals to coat the blue LED to artificially generate a version of white light.
This is referred to as the Colour Rendering Index, CRI. The closer the rating is to a value of 100 the better the quality of the generated light. Quality LED products are now offering a CRI of 95.
We all know the older lighting technologies, incandescent and halogen, by the Wattage rating, we know how much light a 100 W bulb generates, but LED’s are different. The Wattage rating of an LED is not an accurate indication of how much light it will generate owing to variations in efficiency from manufacturer, make and model.
Lumen output is the Rating to look for on LED’s. A 100 W light bulb traditionally generates about 1000 Lumen and a 50W Halogen down light about 900 Lumen, an efficiency of 10-20 Lumen per Watt. LED’s currently offer 50-100 Lumen per Watt depending on the type and design of the fitting.
Ongoing development will see LED’s increase considerably in efficiency. Lab tests are currently achieving up to 300 Lumen per Watt.
LED bulbs are available in a range of “Colours”, our traditional incandescent or halogen lights operated by heating up a filament which in turn gave off light, this light is yellowish in nature, which is what we refer to as Warm White, if we wanted a whiter light we had to opt for CFL or Fluorescent.
LED’s have a colour rating, a figure measured in Kelvin. A rating of 2700-3000 Kelvin is the same Warm White colour generated by the halogen and incandescent. Cheaper LED’s may simply generate an artificial yellowish colour.
A Kelvin rating of 4000 Kelvin is considered to be a Natural White colour and 6000 Kelvin a Pure White colour, bordering on bluish with the cheaper LED’s.
LED’s are an Electronic Device, even LED’s that claim to be dimmable may not operate on your existing dimmers, but require the use of a tested and approved dimmer. Use of non approved dimmers can damage the dimmer, the LED’s or both.
LED Lighting offers design flexibility previously not possible with traditional lighting. LED’s are small electronic devices controlled by a microprocessor which enables them to be assembled in a huge variety of shapes and sizes, from flexible LED strip right up to powerful flood lights.
LED Lighting offers greatly enhanced lighting control. LED’s are directional so lighting can be directed more accurately where it should be, beam angles can vary according to design.
LED lighting is not only dimmable, but can also change from a cool white to a warm white depending on light level, LED’s are available in a range of colours and even Colour Changing.
Incredible lighting moods can be achieved with proper LED Lighting design, the feeling or mood of a room can be totally transformed according to your needs just by adjusting the lighting. Adjust light levels, change colours, the options are virtually limitless.
LED Strip light, can be cut to length, ideal for decorative lighting, available in many colours or colour changing RGB.
LED Flood Light, low power consumption and long life span make them ideal for security lighting.
Led’s are available in a range of shapes and sizes to replace most existing bulbs.
Create incredible lighting effects by changing light levels and colours.
