The world has watched how light bulbs evolve and solid state lighting is imminently the next generation of efficient lighting. The hundred year-old incandescent light bulb has served humanity well and for the longest time. But things change as do peopleâ€™s lighting needs.
Pick the winner: LED vs Incandescent
LED light bulbs areÂ increasingly finding theirÂ way into homes, offices, buildings, streets and other indoor and outdoor spaces for good reason. What exactly are the differences that are making LEDs the preferred choice over incandescent light bulbs?
How They Operate
Traditional incandescent bulbs burn a filament to produce warm light. But only 10% of the energy they consume is converted to light with the rest being wasted as heat, making them less efficient than their LED counterparts. LEDs, on the other hand, have diodes that act as semiconductors and produce light without burning anything. They are more efficient than other light bulbs because they use 75 to 80% less energy to deliver the same amount and quality of light. They also run cool with the help of heat sinks or heat fins that help dissipate heat, effectively conserving electricity and reducing costs.
An LED light bulb gets an easy win in this category because it can live up to 50,000 hours compared to the 1,000 hours of its incandescent rival. To illustrate, if an incandescent bulb is turned on for five hours every day under normal conditions, it would burn out after over six months. On the other hand, with the same daily use, an LED light bulb would last up to 333 months or roughly 27 years. Why is this so? LEDs run on diodes often made of silicon that act as semiconductors of heat. Silicon is extremely resistant to heat with exceptionally high boiling points, hence it is not prone to burning out.
As to wattage, a 60-watt incandescent light bulb achieves the same brightness as an 8-watt LED light bulb. This definitely spells a lot less energy consumption for LED lights, reducing the cost of operation and saving significant energy dollars for consumers. Their longer lifespan, durability and solid state technology also contribute to their efficiency, freeing users the hassle of maintaining, buying and changing bulbs every so often.
Range of Applications
Currently one of the most energy efficient types of bulbs, LEDs allow for a range of application choices aside from general lighting uses. With several beam angle options to choose from, they can be used as spot lights, flood lights, street lights, track lights or directional lights for hard-to-reach corners and nooks.
