The most common type of floodlight is the metal-halide lamp, which emits a bright white light (typically 75-100 lumens/Watt). Sodium-vapor lamps are also commonly used for sporting events, as they have a very high lumen-to-watt ratio (typically 80–140 lumens/Watt), making them a cost-effective choice when certain lux levels must be provided.
In the recent years there have been new developments, and LED technology has come a long way. Now LED flood lights are bright enough to be used for illumination purposes on large sport fields. The main reason for the use of LEDs is the lower power consumption and the fact that LED bulbs last longer.
The first LED lit sports field in the United Kingdom was switched on at Taunton Vale Sports Club on 24 March 2014.
LED Flood Lights and Home Security
Deter thieves and light up your exterior with LED security lights and flood lights. Protecting your home or commercial property is a priority, but one that shouldn’t have to cost the earth.
Using 90% less energy than a halogen floodlight, with no compromise on performance, an LED floodlight can pay itself off within six months. With a range of styles and different colour casings, you can make sure that you get the right security light for your building.
Built to stand the test of time, an LED floodlight will outlive the halogen equivalent by miles, making it a sound investment.
Light-emitting diodes (LED) are semiconductors. As electrons pass through this type of semiconductor, it turns into light. Compared to incandescent and CFL bulbs,LED lights are more efficient at turning energy into light. Therefore, less of the energy radiates from the bulb as heat.
Why are “Floodlights” called floodlights?
Floodlight provide uniform flow of light in a large area, just like flood.
