Essentials 5 (ES5)

High Performance LED High Bays

The Essentials 5 provides the highest reliability and performance in all applications, including heavy industrial and harsh environments. ES5 is the only LED high bay in the industry with a 10 year guaranteed performance, covering lumen maintenance (L70) and LED driver.

The new ultra high efficacy models (Model U) achieve up to 214 lumens per watt, becoming the most efficient LED high bay on the market, and can withstand up to 65°C (149°F) ambient temperatures with its best-in-class thermal design and extruded aluminum heat sinks.

This new generation comes in a smaller footprint with higher efficacies, improved optics, a new conformal coating option, standard control options, and even enterprise level advanced controls using our UltraLink Bluetooth mesh.

Applications: Automotive Lighting, Commercial Lighting, Convention Center Lighting, Hangar Lighting, Industrial Lighting, Sports Lighting, Warehouse Lighting.


Our superior thermal management and high quality components allow us to offer the best warranty in the lighting industry.

Performance of the light fixture is guaranteed for 10 years, including lumen maintenance (L70), color temperature, and LED driver. “Defective” is considered if ten percent (10%) or more of the LEDs, per product, are non‐operating LEDs, total lumen depreciation exceeds 30% (L70), or color temperature has shifted more than 500° Kelvin within the warranty period. See terms and conditions at

Aluminum Construction

Extruded aluminum heat sinks and aluminum wireway keep the LEDs and driver at low temperatures, achieving longer life and higher efficacy.

Designed for Industrial Environments

Rated up to 65°C. Options available for dust-proof (IP5X), wet location, surge protection (up to 20kA), impact resistance (IK08), and wire guards.

Superior Thermal Design

Individual heat sinks per LED module with ample separation from other modules and the driver ensures maximum heat dissipation and airflow through the fixture.

Features & Specifications

  • Extruded Aluminum Heat Sinks: Provide optimal thermal management by decreasing LED junction temperature, ensuring longer life and higher efficacy. LED boards attached to the heat sink using a high quality thermally conductive adhesive rather than screws or rivets. This ensures good contact between PCB and heat sinks for excellent thermal conductivity.
  • LED Boards: FR4 PCB is used to limit stress on solder joints by matching coefficient of thermal expansion between the LED and the PCB more closely.
  • Power Supply Access: Wireway cover allows easy access and quick wiring. Hole accepting 3/4” stem (not centered) and also 1/2” KO near top end of wire way. If center stem mount is required, select STEM in mounting options.
  • Wire Guards: Optional factory-installed wire guards upgrade impact protection to IK10 for all polycarbonate lenses (CL, AL, NW) and to IK08 for acrylic lenses (FR).
  • Power Input: 120-277V or 347-480 (50/60Hz), typical, depending on model.
  • Power Factor: Greater than 0.9 (0.96–0.99 typical).
  • Total Harmonic Distortion: Less than 20%, 10% typical.
  • Surge Protection: Standard is 6kV for drivers. Additional surge protection is available. All HV orders will have 10kV SRG automatically added (contact sales for questions).
  • Driver Quick Disconnect: Available as an option.
  • Emergency Battery Backup (EMB and EMB2): EMB produces ~2,700 lumens for a minimum of 90 minutes. EMB2 produces ~4,300 lumens for a minimum of 90 minutes. EMB has 15 watts output, EMB2 has 25 watts output. Factory installation only, not able to be field installed. Available in LV and HV. Contact factory for details.
  • Environment: Dry/Damp, for interior applications (IP4X). Dust-resistant LED modules, dust-proof (IP5X) option available. Wet location available. Impact protection up to IK10.
  • Ambient Range Operation: -40°C up to 65°C (-40°F up to 149°F), depending on model.
  • CCT: 3500K, 4000K and 5000K standard, other CCT available (extended lead time).
  • CRI: 70+, 80+, 90+
  • Lenses: UV stable polycarbonate Clear, Aisle and Narrow, Conformal coating and Frosted available.
  • Field-Replaceable Lenses: Clear, Frosted, Aisle, and Narrow.
  • Rotatable LED Modules: Field adjustable rotating modules. Easily adjusted outer modules with stops at 45°, 90° and 135°. Factory set at 0°. Allows for customizing light pattern to suit individual situations.
  • Fixture is cable ready (CRM). Other options are STEM (comes with a 3/4” opening in the center of the STEM box), HOOK and surface mount (with optional MBR). MBR reduces ambient range by 5°C when mounted flush to junction box.
  • Dimming: 0-10V standard. Dimming range 100% to 10%.
  • UltraLink Bluetooth® Controls: Advanced wireless controls available. Requires commissioning in the field, contact factory.
  • Avi-on Intelligent Controls: Bluetooth® advanced wireless controls available. Requires commissioning in the field, contact factory.
  • Occupancy and Dimming Occupancy Sensors: Optional – factory installed photocell sensors. IR-TEC and Wattstopper available, other options available upon request.
  • Guaranteed Performance: 10-year product warranty covers fixture, lumen maintenance (L70), color temperature, and LED driver.
  • Conforms to ETL listed (UL 1598:2021 Ed. 5)
  • UL Wet Location.
  • RoHS compliant.
  • EMI: FCC 47CFR 15:2022 and ICES-005:2018.
