LED lighting is not a new idea, having been around in technical applications (mainly computers and machinery) since the early 1960’s, but it’s only in recent years that the technology has reached the level where white LED light can be successfully applied in commercial and domestic lighting situations. The current LED lights use a technology which allows them to produce a similar amount of light for significantly less power than the current range of light globes.

Traditional lighting is very inefficient in converting electricity to light, with the majority of the electrical energy used by the globe being wasted as heat. Incandescent and Halogen globes will lose over 90% of their energy as heat, so that only a small percentage of energy is converted into light.

LED globes, on the other hand, emit much smaller amounts of heat in the generation of their light, meaning they achieve a far greater efficiency than the Halogens and CFL’s, so that a similar amount of light is produced for a significantly lower amount of power.

With the price of electricity as it is today, and with further increases projected, domestic and commercial property owners need to be able to reduce their electricity usage.

These LED globes are the true energy saving lights of the future, realising large saving in electricity use and achieving a payback period of generally less than two years.

The life span of the average LED light globe is far in excess of any of the other globes currently being used today, by a factor of 5 when compared to CFL’s, and a factor of 25 against Halogen globes. This reduces the number of globe changes that are needed, thereby save the recurrent purchase costs of the previous globes, and the labour costs associated with the changeover.

Significantly less power used in generating similar amounts of light.

• almost no heat is produced in the operation of the light

• air conditioning cost are reduced due to less dispersed heat

• long life means fewer globe changes over an equivalent amount of time

• available in a wide ‘colour temperature’ range, from warm white to cool white

• solid state construction, meaning greater protection against internal damage or breakage

• no hazardous materials are present in the globes

• do not contain any harmful substances such as mercury(CFL’s) or fluorine (Halogens), and are RoHS approved

With the increase in electricity prices projected to occur over the next few years, and the ongoing requirement to reduce carbon output, energy efficiency is becoming a major consideration for all commercial buildings. Here at Energy Delta, we believe that one way of achieving a significant reduction in energy consumption is by switching to energy efficient LED lighting. On average, the cost reduction on the lighting component of an energy bill will be in the order of 45% – 90%, depending on the mix of lighting used in the building.

LED globes use much less power to generate a similar amount of light, and this lower power consumption will directly reduce the monthly power bill. By using less energy, and by nature of the way they operate, the LED globes also generate significantly less heat, which will translate into additional savings on the amount of power that the air-conditioning use.
