An LED lamp (or LED light bulb) is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light.  LED achieved tunable color temperature lamps over a range of 2700 K to 6500 K.


LEDs offer numerous advantages over other lighting technologies. Professional users and home consumers profit to the same extent from limitless design possibilities based on a variety of color, compact dimensions and flexibility of the LED modules. On the basis of the low energy consumption, long lifetime and greater service intervals, high economic benefits are produced. In addition, individual LEDs provide maximum reliability even in difficult environmental conditions.


Energy Sustainability begins with conservation and energy savings. LED Lighting applications will reduce wasteful energy by 50%-90% compared to other conventional lighting products.


LED Lights not only consume a fraction of the energy consumed by traditional lighting, it provides a double benefit of being longer lasting and environmentally friendly. Unlike traditional lighting products, LEDs do not contain Mercury, a potentially hazardous substance that poses a threat of environmental damage. LED light bulbs can be reycled.


LED Lighting technologies assist to reduce the carbon footprint set by developed countries. Use LED for a better future without a commensurate increase in green house gas emissions.


LEDs are highly rugged and feature no filament that can be damaged due to shock and vibrations. Do not flicker.  The operational life of LEDs last up to 30 to 50 times longer than traditional lighting products, while maintaining consistent light output over life.


The key strength of LED lighting is reduced power consumption. LEDs approaches 80% efficiency; which means 80% of the electrical energy is converted into light energy. LED allows a precise, purposeful light and reflects a variety of properties, while providing improved uniformity and visibility.


While the initial cost of LED lights is higher, savings with LED occur over time by taking advantage of their longevity.
Conventional lighting products real costs are: enormous maintenance expenses; lifespan,  labor, and parts. With LED, these costs can be virtually eliminated. A significant factor for a large number of installed bulbs such as in warehouses, retail stores, etc.  Not to forget the energy cost savings.



The longer a light source is in use, the greater the economic and ecological advantages are. The semiconductor’s minimal decrease in luminous flux over the operation period causes the LED to be able to remain in maintenance-free use, in many areas of application, longer than other light sources


The operating life (L70B50) of LEDs can easily exceed 50,000 hours. Compared to other light sources, LEDs very rarely fail. Only the luminous flux is slightly reduced over the operating period. In practice, LEDs are virtually service-free during their entire period of use, depending on the particular application. The influential factors on the individual LED, described below, can also affect the entire LED module.


When light is produced, heat occurs, which has an effect both on the life cycle and on the LED’s luminous flux. This applies to both the individual LED and to an entire LED module. That is why it is essential to divert the heat by the best possible installation method or by suitable heat sinks. The basic principle is as follows: The cooler it is, the longer the LED’s life cycle and the more efficient and brighter it is.


The causes of the occurrence of mechanical forces can be versatile. This can occur during LED manufacture, assembly or handling and during the use of certain materials which develop mechanical forces during large temperature fluctuations. If a LED is exposed to such forces, this can have a negative effect on its operating life, or can even destroy it.


Every LED, and also every LED module, can be operated within a specific current range. The lower the current is within this range, the less energy is released and the lower the heat production is, which has a direct effect on the operating life


The particular LED’s housing design plays an important role in the ageing process of the particular component, influenced by the light emitted by the chip. With many housing designs, the built-in reflector ages a lot in the first few hundred operating hours as a result of the high intensity and luminance of the light emitted by the chip.


The LED itself is robust, non-sensitive, vibration-proof and unbreakable. If it is used properly, dampness is also not a problem: as it is not the LED itself but various metal parts, connections and electronic components inside a LED module that are sensitive and may corrode and can thus cause the module to fail. A suitable choice of materials for the LED prevents corrosion. Dampness protection is also absolutely necessary, in order to achieve the highest possible operating life of the LED modules.


Stress to the LED caused by chemical influences can vary greatly depending on the application location. For this reason, all environmental conditions must be taken into consideration when planning an LED lighting system. The following effects, among other things, have a negative effect on the operating life:

– Corrosive atmosphere (air with high sulfur dioxide content)

– Coastal climate with medium salt content

– Chemical industry

– Swimming pools with medium chloride content.


LM-79 establishes testing methodology to create a level field for product evaluation. It looks at 25C ambient, power supply, stabilization, orientation, electrical instruments, and testing equipment.

LM-79 defines what information is required; total light output, voltage, current, power, calculates efficacy, lumen distribution, CCT, CRI, spectral distribution, testing lab, and equipment used.

LM-79 requires that solid state lighting products be tested to “Absolute Photometry.” Conventional HID/Fluorescent uses “Relative Photometry.”

Absolute Photometry is lumen output of LED based luminaires and is dependent on the chip, thermal management, drive current, and optical system. LED based luminaires and lamps must be tested as a complete unit or system


LED luminaires and lamps do not “fail” like conventional sources

  • This is known as L70
  • Total life is known as L70B50

LED luminaires and lamps gradually decrease in output over time

IES has determined end of life of LED products to be when the lumen output is 70% of its initial (30% depreciation)

  • This is known as L70
  • Total life is known as L70B50

L70B50 is the amount of time for the light output of 50% of a set of LEDs to fall to 70% of their original light output under a given set of operating conditions.

The DOE has suggested that useful life of LEDs to be 35,000 to 50,000 hours.

Claims beyond these values cannot currently be substantiated using available approved methods, or historical data to support claims beyond these levels.

LM-80 however does not provide testing procedures for a complete luminaire only to measure the lumen maintenance of a LED package, array or module at 6,000 hours.


There are many reasons for you to make the change to LED, some of which can be seen below:

Is lighting going to make that much difference?

By up to 85% from traditional incandescent light source. Lighting usually accounts for up to 40% of your electricity bill.

What are the effects on the environment?

LED lighting drastically reduces the carbon footprint of your home or business, and emits up to 70% less UV light than halogen bulbs.

How long will an LED last for?

Compared with a regular halogen bulb, LEDs can last up to 20 times as long – that’s a lifespan of up to 40,000 hours. Switch to LED, leave them on constantly and you should find they’re still working, 5 years later! (Halogen will tend to burn out after roughly 83 days of constant use.)

Do LED bulbs have any additional advantages?

Our range of LED bulbs have been designed with you in mind. They require minimum maintenance, offer reduced heat lose and in turn can help reduce your air conditioning bills dramatically, in addition, our range of LED bulbs are ahead of current legislation. a direct effect on the operating life.

LED Environmental Credentials?

Lots of small changes all add up to a significantly BIG change. We want to help you become part of a good thing by installing our energy saving LED bulbs.

Cutting Carbon The Easy Way?

Replace one of your current inefficient halogen lamps with an LED option and this will enable you to reduce 250kg of CO2 emissions (Kg/year).eve the highest possible operating life of the LED modules.

Requirement to Fight Global Warming?

The targets set at the 1997 Kyoto Protocol for CO2 reduction could be comfortably achieved if just the business and manufacturing sectors made the change to LED.
If half of all households made the change then we would exceed those targets set.
