The FL Series LED Flood Lights from E-LED Lighting are manufactured using the most modern components available on the market. Although many floodlights look alike, there is a distinct difference in the manufacturing process of E-LED Flood Lights versus some of the other brands out there. E-LED Lighting flood lights were originally designed to operate in the harsh environments of the commercial marine industry. They use ceramic based chip LEDs from Bridgelux (Made in the USA) and the drivers are mounted to a vibration resistant housing. All fasteners, rings, and nuts, including the bracket, are made of high-quality marine grade A4 316 stainless steel. It?s important to note the lumens/watt when comparing flood lights. E-LED flood lights have a 100 lumen/watt light output. Therefore our 10W has a 1,000 lumen output, our 30W has a 3,000 lumen output, and so on. E-LED floodlights are available in 10W, 30W, 50W, and 80W models which is a halogen equivalent range of 50-700 Watts. They?re available in a grey or white double powder coat finish which eliminates the potential for corrosion from harsh or saltwater environments. All gaskets are specially designed and manufactured for use in harsh environments and are saltwater, oil, and lubricant resistant. The housings also feature a special ventilation gland which is used to ensure the air pressure inside the housing remains the same as the ambient environment to prevent fogging.
