Floodlights have numerous applications and can be used in different areas that need bright and clear lighting. Driveways of private homes, stadiums and other outdoor spaces need the directional light that floodlights provide. They provide increased security for businesses and residences alike. The one downside is that, in some cases, they tend to be used up to 10 hours every night. The power and maintenance bills can add up to quite a whopping amount. Another glaring disadvantage is light pollution and the environmental impact that they have.
Halogen-based floodlights are used in most places. Inexpensive replacement bulbs are easily available and provide a higher output per watt. Floodlights used in stadiums are generally metal halide ones and emit a bright bluish light. These are ideal for illuminating large open spaces, but the bulbs are not long-lasting and the light tends to pollute the air as well. Since both, metal halide and halogen bulbs have a short lifespan their maintenance costs are quite steep.
Society is getting increasingly more conscious about the environment and that is a good thing. This also means that more environment-friendly lighting options are being sought and opted for. With this in mind, LED lights are an obvious choice. These are now found in floodlights and their illumination capacity is almost on par with halogen ones. For most consumers, the cost factor is a major consideration. A well-informed decision can be taken by accounting for the initial price of the product, the power-output and running costs.
For instance, a 10-watt LED floodlight will emit 700 lumens, which is slightly on the lower side than a 100W halogen bulb. A 30W LED floodlight will emit 2400 lumens which is on par with a 350W halogen light. At 4000 lumens, a 50W LED floodlight can provide the same amount of brightness that a 500W halogen does. Essentially, a lower wattage translates into lower electricity-consumption. This automatically drives down the costs and reduces the impact on the environment.
The one big disadvantage of an LED floodlight is probably its initial price. A 30W ED lamp will cost around £50, while a 350W halogen lamp will cost less than £8. You will have to shell-out £250 for a 100W LED lamp. On the other hand a 400W metal halide lamp will cost £50-£150. A look at the comparable costs might make you veer towards halogen lamps but when you take running costs into consideration, you realise the true advantage of opting for LED lamps.
LED floodlights come out tops on all measures of running costs. Using a 500W halogen bulb that costs under £10 for 8 hours every day, would necessitate that the bulb be replaced almost every two months and would run up power bills of up to £175, annually. On the other hand a £80, 50W LED will provide up to 50,000 hrs of illumination. At an average of 8 hrs per day, that works out to almost 2 years of lighting at an annual running cost of £17.50 every year. Effectively, this works out to only a third of the running cost of a halogen lamp.
An LED floodlight provides cost-effective and environment-friendly lighting. Directional lighting leads to less pollution, the instantaneous on-off function improves efficiency while its longevity and 90% reduction in power consumption reduces running costs. In 2012, The Central New York Raceway Park was in the lead with LED floodlight installations. Premier League football clubs have shown a lot of interest in making a switch and the UK is all set to go the LED way.
