LED Bulbs Explained



LED (light-emitting diodes) are a type of electronic light source. LEDs are different from conventional light sources such as incandescent and halogen lamps. They last much longer, consume far less energy and emit very little heat. They are highly durable and do not feature fragile elements such as glass tubes or filaments; they are safer because they do not contain any mercury or lead.

LED bulbs use upto 90% less energy than conventional bulbs of equivalent brightness. LEDs are far more efficient at converting electricity, measured in watts, into light, which is measured in lumens. For example a 4W LED bulb can easily achieve light output comparable to a 50W halogen bulb.

Another advantage of LED bulbs is its outstanding life time expectation due to very efficient thermal management, LED bulbs are able to remove heat through heat sinks, to help prolong life expectancy of the bulb by slowing down lumen depreciation. A good LED bulb should last up to 50,000 hours.

Lighting can account for 20% of the overall energy bill for households and businesses alike. By switching to LED bulbs a considerable amount of money can be saved due to the lower wattages of the products, and the far longer life expectancy, once you have switched to LED bulbs, you will start to save money in less than a year.

LED bulbs are much safer than conventional bulbs, no harmful metals, give off little heat after prolonged use, absence of glass, so no jagged edges or broken glass to worry about. LEDs are eco-friendly as they cut carbon emissions (CO2), by using less energy.

LED bulbs are retrofit and are designed to work with existing light fittings and be can used as direct replacements. They are available in three colours, Warm White, Cool White and Daylight. Warm White is usually used in domestic capacities and is the normal colour associated with standard halogen bulbs, relaxing and comfortable. Cool White is a cooler white often associated with fluorescent tubes in offices or retail outlets, bright and clean. Daylight colour is a very white, bluish white and provides a very crisp light, energetic and refreshing. They are very durable and can stand very cold and rough conditions, also resistant to shock, vibration and external impacts, they make the perfect choice for all modern lighting conditions.
