High power led flood light will focus on high-mast lighting, which has similarities to the requirements for street and roadway lighting. The difference is that the masts are often much taller, 30 meters or more, compared to 10 to 20 meters for street lights. High-mast outdoor area lighting at airports, and car parking areas, high power IP65 led flood light is replacing its HPS high-mast floodlights with LED modules to save energy costs.
Clearly, the energy saving potential in these high-power, high-mast type applications is enormous. Fixtures that typically use 1000 W HID, metal halide or HPS lighting fixtures can easily be replaced by 150 , 200, 300 or 400 500W LED fixtures. Light output can be anywhere from 20,000 to as much as 50,000 lm flux.
With LEDs, a CRI of 70 to 90 is easily achieved, which is important for better nighttime visibility, and is therefore regarded as a safety issue. Colors are rendered more naturally, and they avoid the yellow hues common with HPS light sources (CRI around 25), which can be a real problem in poor weather conditions.
The ability to select color temperature is important too, either as a constant or programmable feature. With a range from 3000K to 6000K, light quality can be specified to match the precise nature of the target area to be illuminated. Lifetime is typically guaranteed over 50,000 hours, with a warranty of 5 years, resulting in the next significant cost saving factor: reduced maintenance.
High-mast LED lighting is not only appropriate for airport aprons lighting and roadways lighting. by upgrading its site lighting from HPS to LED high-mast luminaires. transport and container facilities, railway yards, and truck stops, as well as sports and entertainment stadiums. such as motorway interchanges and toll booth plazas.
