The LS411COB is a high-performance luminaire that harnesses next-generation Chip on Board (COB) LED technology to deliver exceptional illumination and energy efficiency from a compact form factor. This advanced design enables high lumen density, making it ideal for applications requiring broad light distribution, such as general landscape lighting or areas where a soft edge rather than a sharp cutoff is preferred. By combining this powerful light source with traditional lamp-and-reflector-style optics, the LS411COB offers a balanced beam spread that enhances visibility and coverage.
This fixture supports a wide range of color temperatures to suit various environments, including 3000K, 4000K, and 5000K options, all with an 80 CRI for accurate color rendering. At 3000K, it produces 1,414 lumens with a peak intensity of 6,681 candela. At 4000K, output rises to 1,488 lumens with a peak of 7,184 candela, while the 5000K variant delivers up to 1,494 lumens and a peak intensity of 7,207 candela. Each configuration achieves a luminous efficacy of 58–60 lumens per watt, ensuring effective energy use across applications.
The LS411COB operates at 20 watts of LED power, with a nominal consumption of 25.6 watts, and is designed to run on universal mains voltage (100–277V AC, 50/60Hz). Built to withstand demanding environments, it features a marine-grade LM20 die-cast aluminum housing with a durable powder-coated finish. The luminaire is installed using a concrete anchor, ensuring stability in outdoor settings.
Engineered for reliability, the LS411COB operates within a temperature range of -20°C to 50°C (-4°F to 122°F), and its surface remains safe to touch, maintaining a HumanTouch™ compliant temperature of ≤65°C (≤149°F). With an IP67 rating, it is fully protected against dust and temporary immersion in water, making it suitable for dry, damp, or wet outdoor locations. This robust, versatile fixture represents a significant evolution from its discrete LED predecessor, delivering increased performance while retaining installation flexibility and optical options.
