LED Downlights – Innovative Lighting For The 21st Century
Conventional lighting has served mankind well for many decades ever since Thomas Edison successfully commercialized the familiar light globe. That so-called incandescent technology is now outdated. Enter the new buzz, light emitting diodes (LEDs). LED downlights increasingly being installed both indoors and outdoors, sometimes in very challenging and harsh environments. For example, they are popular among mariners and aviators. https://www.shoponova.com/
LEDs deliver at least three key advantages versus incandescent light globes. They burn less electrical energy, cost less to manufacture and have a longer operational life. Those three pluses are attractive to consumers and provide a significant financial incentive to switch to the new technology plus they are a healthier choice for the environment to boot.
Low energy requirement is their biggest advantage. Indicatively, one watt of electricity allows an LED to deliver about 70 lumens. Depending on their capacity, most LEDs require between 0.5 to 5 watts of power. A second major benefit is that LEDs require much less energy to be made in the first place. Both these savings mean they have a tiny carbon footprint.
An LED lasts anywhere from about 40,000 up to a staggering 100,000 hrs of continuous working life. That means changing a unit as infrequently as once every 11.5 years. By comparison, incandescent globes might last about 2-4,000 hrs. Illumination erosion is minimal, with a maximum degradation of about 20 percent after 40,000 hrs.
The long working life of an LED reflects the interplay of several features. For one thing, they do not have any glass or filament parts. Next, they generate almost no heat. Finally, they are made from a very durable resin that is difficult to burn or break.
Because of their minimal power draw, minimal heat and lack of toxic fumes or materials (like mercury), LEDs are rated high safety criteria. Toxic materials are often present found in conventional. This is an especially relevant point for lighting in spaces occupied by toddlers and children.
