Performance & Light Output

The CHB-18L delivers 18,200 lumens at 140W with a consistent 130 lm/W efficacy at the single 5000K color temperature. High-quality glass optics distribute light evenly with a glare-free pattern suited to open-span ceiling heights of 20–35 feet. LM80-tested SMD LED chips confirm 80 CRI and a rated life of 100,000 hours at L70.

Lens & Optics

High-quality glass optics provide glare-free, uniform light distribution across the full fixture aperture. The round form factor and reflector geometry are optimized for wide-area illumination in ceiling heights of 20–35 feet at 140W output. Optional aluminum reflector (CHB-ALR) and prismatic reflector (CHB-PCR) accessories are available to tune beam distribution for specific applications.

Smart & Control Features

The CHB-18L includes 0-10V dimming (10–100%) as standard on every unit. The UL-qualified integrated LED driver supports continuous dimming for compatibility with standard 0-10V wall controls and energy management systems. No additional control accessories are confirmed on the spec sheet for this model.

Electrical

The integrated, UL-qualified LED driver provides universal 120–277V input (50/60 Hz) as standard. A 200–480V driver is available as a special order (suffix -H). The driver supports 0-10V continuous dimming from 10–100%. The fixture is mercury-free and RoHS compliant. 200–480V configuration uses the CHB-18L-H-50K-D10 catalog number.

Construction

Heavy die-cast aluminum housing with a polyester powder-coated finish offers corrosion resistance against extreme climate changes. The round fixture measures 16.45" L × 11.73" W × 6.75" H and is IP65-rated for damp location installation. Mercury-free construction with RoHS compliant materials.

Installation & Mounting

The CHB-18L mounts via pendant or hook — hardware for both methods is included. Recommended ceiling heights: 20–35 feet at 140W. Available accessories (ordered separately):

• CHB-ALR — Aluminum reflector
• CHB-PCR — Prismatic reflector
• CHB-WG — Wire guard
• CHB-PMS — Pendant mount slider
• CHB-SP — Surge protector
• CHB-SC2 — Safety cable, 2 ft
• CHB-TLC — Twist-lock cable

Certifications & Rebates

cETL and ETL listed for U.S. and Canada — covering commercial and industrial applications in damp locations. DLC certified — eligible for utility rebate programs nationally (verify current DLC product code at designlights.org). RoHS compliant; mercury-free construction.

Typical Applications

• High-Ceiling Warehouses & Distribution Centers: 18,200lm output at 140W suits ceiling heights of 20–35 feet with IP65 damp rating for humid environments
