The Nemalux ZLM is a powerful industrial-grade LED floodlight designed to deliver high-intensity illumination in rugged environments. Developed specifically for demanding applications such as drilling rig crown lighting and lease site illumination, the ZLM offers exceptional lumen output in a compact, lightweight form. With options ranging from 28,000 to 112,000 lumens through its modular design, the ZLM stands out as a high mast luminaire capable of handling extreme installation heights while maintaining a superior lumen-to-weight ratio. Its compact build reduces wind load, making it ideal for mounting on structures with limited load capacity.
Engineered for versatility, the ZLM supports installations from 30 to 160 feet high, delivering targeted and efficient lighting via multiple optical profiles, including narrow, wide, and asymmetric beam distributions. This flexibility ensures high visibility while minimizing light spill and trespass. Constructed from die-cast and extruded marine-grade aluminum, the ZLM’s housing features a Type II anodized finish and powder-coated end caps. The robust aluminum body and impact-resistant polycarbonate lens allow it to withstand outdoor exposure in harsh environments, including the extreme climates of northern regions.
Each light engine and power supply section is sealed to an IP66 rating, providing resistance against high-pressure washdowns and ensuring long-term protection from dust and water ingress. The actively cooled design incorporates outdoor-rated fans and thermal management systems to ensure reliable performance, even at ambient temperatures ranging from -40°C to +45°C (with potential for up to +55°C pending validation). Redundant systems built into the luminaire help maintain uptime and extend the operational life of the components.
The ZLM is certified for general location use under UL 1598, CSA C22.2 No. 250.0, and CSA C22.2 No. 250.13, making it suitable for a wide range of industrial deployments. Standard electrical configurations include 120-277 VAC input voltage, with support for 0-10V dimming and Class 1 wiring. A variety of connector options are available, including Turck MiniFast quick-connect systems and 5-conductor flying leads, with customizable lengths for specific application needs.
Typical applications for the ZLM include drilling rigs, high mast towers, marine port terminals, construction sites, light towers, cranes, and train yards. Mounting is simplified through adjustable yoke brackets, allowing single, dual, or quad module configurations to be aimed precisely for optimal coverage. A built-in safety harness interface ensures secure installations in elevated or vibration-prone locations.
In addition to its exceptional mechanical and electrical specifications, the ZLM delivers up to 28,800 lumens per module at a color temperature of 5000K (with custom options from 2700K to 6500K). High CRI versions are also available upon request. The luminaire’s LED light engines have been tested to LM-80 standards, achieving a lifetime rating of over 60,500 hours based on CREE’s long-term performance data.
The standard ZLM module weighs approximately 12.7 kg (28 lbs), while the dual-module ZLM2 configuration weighs 24.7 kg (54.5 lbs). These compact but powerful units provide reliable, high-output lighting in environments where performance, durability, and safety are paramount. With a thoughtful design and field-proven reliability, the Nemalux ZLM continues to set the standard for industrial floodlighting in the most extreme conditions.
