LED lights have increasingly become a viable lighting option in recent years, given the quality of output and durability. Also, given the reduction in cost of LED lights, they will possibly overtake conventional incandescent and fluorescent lights.
This write-up is meant to highlight the benefits of switching to LED lights.
In comparison to incandescent, fluorescent or halogen lights, the electricity consumption of LED lights is 50 per cent less. This can really benefit places where lighting has to be on for long periods. One unique feature of LED lights is that they emit light hemispherically unlike traditional lighting sources, which emit light and energy in all directions. As a result, light and energy consumption is reduced with LED lights.
High-quality LEDs have an incredible lifespan of nearly 50,000 hours. In contrast, incandescent lights last for only about 1,000 hours and fluorescent lights for about 10,000 hours. This translates to reduced cost in replacing lights frequently, along with the associated labor costs, especially large commercial places, such as shopping complexes, manufacturing units, and hotels.
Operating at Lower Temperatures
The operational efficiency of LED lights rises with fall in temperature. As a result, LED lights are ideal to be used in refrigerated display units and cold storages; this also makes them a very viable option to be used in parking areas, buildings and signages, especially at night and more so in countries in cold regions.
LED lights are sturdy and can withstand vibrations and impacts as they are not encased in glass or quartz casings like conventional lights. LED lights are soldered to circuit boards that are relatively better off in handling any direct impact.
Light Up Instantly
Fluorescent and HID lights generally take some time (around 3-4 minutes) before reaching their maximum output. In contrast, LEDs produce maximum output almost instantly and have negligible re-strike delays. A re-strike delay is the time between the switch is turned on and light is visible.
Resistance to Rapid Cycling
Conventional lights are affected by the constant switching on and off, unlike LED lights that are immune to the wear and tear of this rapid cycling. This makes LED lights an ideal source for flashing light displays as well as in occupancy and daylight sensors.
Can be Controlled
Being semiconductor devices, the intensity of LED lights can be easily controlled by dimming them to almost 10% of intensity. Another benefit is that dimming occurs smoothly and not in steps.
Near-zero IR & UV Radiation
Conventional lights convert less than 10% of power to visible light, the majority of the rest being converted to infrared (IR) or radiated heat. IR and UV radiation by LED lights is almost zero, which makes them safe for people and material.
While the advantages mentioned here are compelling reasons to switch to LED lights, the choice should absolutely be based on your needs and the cost factor. Having said this, it’s undeniable that LED lights are the future. p>
