Multi-Pack of 3; Built-In Microwave Sensor for Higher Energy Savings You re missing out on a massive energy-saving opportunity if you re still not using auto-on/off functions from your lights. They re highly sought after in residential, commercial, and industrial settings, specifically for their energy-saving potential. This pack has three LED High Bay Lights with a Microwave Sensor . Lights equipped with this technology automatically turn on when movement is detected and off when there's none. This means that no lights will run if no one s using them (it's basically what it should be). Microwave sensors outperform PIR (Passive Infrared) sensors in terms of range and coverage. Microwave sensors have a wider range, making them suitable for larger areas such as warehouses, factories, massive gardens, stadiums, sports gyms, etc. Want more flexibility in managing your high-bay lights? Use our remote control with them! With this device, you can switch on/off, dim/brighten, and program your fixtures to accommodate your requirements. Power Switchable - Choose Your Preferred Brightness (110W, 150W or 200W) Wattage is the measurement of power a light fixture consumes. Especially in traditional lighting (incandescent and fluorescent), higher wattage generally means brighter light output. However, this is contested by the more efficient LED lights, where a higher wattage doesn't always mean a significantly brighter bulb. These high bay lights are not part of that exception. You can easily switch between different power outputs , which in turn affect the brightness of the light produced by the fixtures. Power options are 110W, 150W, and 200W . For a wider area or a larger crowd, go for the 200W option. If alone or with a smaller group, you can opt for the 110W power. The 150W option is ideal for those in between. Immense Brightness - 28,000 Lumens Output At its highest power output of only 200W, this LED high bay light is able to produce 28,000 lumens of maximum brightness with a 90-degree beam angle . That s 140 lumens per watt . Something that fluorescent, incandescent, and CFL lights can never hope to accomplish. The average lumen output of high bay lights ranges from 10,000 to 30,000 lumens. The maximum lumens you need depend on the ceiling height and application. It;s best to buy after you've fully examined you space. Ceilings below 20 feet (lower ceilings) are best for 10,000 to 15,000 lumens lighting. Ceilings that are 20 to 30 feet (medium ceilings) need 20,000-25,000 lumens. Ceilings above 30 feet (higher ceilings) need even more lumens: 30,000+. IP65 Rated - Dustproof & Weather Resistant IP (Ingress Protection) ratings indicate the level of protection of an electronic instrument against solid and liquid contaminants. The first number represents the solid protection rating, with the highest being 6, while the second number indicates the liquid protection rating, with the highest being 8.
