LED Work Light: How Efficient Lighting is Transforming the Construction
Evolution of LED Work Light
Ever since the invention of the light bulb by Thomas Edison in 1879, various lighting technologies have emerged to provide illumination for industrial and commercial applications. In the early 20th century, fluorescent lights were developed as an upgrade from incandescent bulbs. These tubular lights provided brighter output while using less energy. However, both incandescent and fluorescent lights had limitations in terms of energy efficiency.
Then in the 1960s, high-intensity discharge (HID) lights such as metal-halide and high-pressure sodium lamps were introduced. Though brighter than previous options, these large lights contained toxic materials like mercury and required high power levels. Maintenance was also an issue as lamps had to be changed frequently.
The LED Work Light
In the late 20th century, light-emitting diodes (LEDs) were first developed and began replacing traditional light sources. LED Work Light offered major advantages over previous lighting technologies. Firstly, they were more efficient as up to 90% of electricity input was converted into light versus only around 10% for incandescent bulbs. This meant LEDs use a fraction of the energy to produce the same amount of luminance.
Additionally, LED lights do not contain pollutants like mercury. They have near-instant on functionality without warm-up time compared to fluorescent tubes. LED lifetime is also significantly longer at over 50,000 hours as opposed to around 1,000-2,000 hours for incandescent bulbs. Maintenance costs are drastically reduced since lights do not require frequent replacement.
