Dialight’s Vigilant LED Low Bay fixtures are engineered to provide exceptional performance, durability, and energy efficiency in industrial and commercial environments with mounting heights ranging from 10 to 20 feet (3 to 6 meters). Leveraging the same cutting-edge technology and robust design as the Vigilant High Bay series, the Low Bay version delivers superior reliability, long service life, and industry-leading safety, all backed by Dialight’s exclusive 10-year warranty. Designed to thrive in harsh and demanding environments, these fixtures are ideal for a wide range of indoor and semi-outdoor applications.
Built for resilience and versatility, the Vigilant LED Low Bay is rated for IP66/67 and NEMA 4X protection, offering full resistance against dust, water ingress, and corrosion. It also meets impact resistance standards up to IK10, depending on lens selection. Lens options include polycarbonate (available in diffused, dome, and clear versions), acrylic, and glass, giving users flexibility to tailor optical performance to specific needs. The fixtures offer an ultra-wide beam distribution and are available in multiple color temperatures—cool white (5000K), neutral white (4000K), and warm white (2700K)—all with a high color rendering index (CRI) of 80 to ensure accurate and vibrant color representation in workspaces.
These luminaires offer a wide lumen output range from 4,400 to 17,200 lumens, providing scalable illumination to meet various application requirements. They support a broad array of mounting options, including hook loop, pendant with ¾" NPT, and various bracket solutions, all with safety retention tabs for secure installation. Electrical integration is also flexible, supporting standard voltages of 100–277 VAC, 120–250 VDC, and 347–480 VAC, and offering electrical connection options such as terminal blocks, flying leads, NEMA plugs, and Reloc OCS/ACS.
Engineered for top-tier energy efficiency, the Vigilant Low Bay achieves up to 148 lumens per watt, helping to reduce energy consumption and operating costs. Select models are DLC Premium certified, further enhancing their appeal for energy rebate programs. Optional battery backup ensures reliable emergency lighting during power outages, while 0-10V dimming capability enables users to tailor light output for energy savings and comfort. The dimming system delivers full brightness at 10 VDC and drops output to below 10% at 0 VDC, with compatibility for occupancy sensors capable of detecting motion up to 40 feet in height.
Built for longevity, the fixture’s power supply is fully potted and sealed for maximum protection, ensuring a mean time between failures (MTBF) of over 300 years with an annual failure rate of less than 0.3% under normal operating conditions. Accelerated life testing confirms the system’s endurance for over 15 years of 24/7 operation. Transient protection is robust, with 100-277 VAC models tested to withstand surges up to 8kV/4kA, and 347-480 VAC models up to 6kV/3kA, per IEEE C62.41 standards. The fixture also maintains excellent power quality, featuring a total harmonic distortion (THD) of less than 20% and a power factor greater than 0.9.
Constructed from copper-free aluminum and protected by a superior dual-coat finish—a chemical-resistant epoxy primer topped with a sealed polyester topcoat—the Vigilant Low Bay ensures durability even in chemically aggressive or high-vibration environments. It has been rigorously tested to withstand vibrations up to 5G for 750,000 cycles (IEC 60068-2-6) and shock loads up to 50G (IEC 60068-2-27), making it well-suited for installation in locations exposed to mechanical stress and movement.
Combining reliability, performance, and energy efficiency with a rugged design and intelligent features, Dialight’s Vigilant LED Low Bay is a premier solution for industrial facilities seeking long-term lighting performance in lower-ceiling environments without compromise.
