The RAB L34 Series is an ultra-economy, lightweight linear LED high bay family engineered for cost-effective illumination of warehouses, retail spaces, and commercial facilities. Both models share the L34’s signature adjustable fold-up wing design — a paracord-locking lens that sets beam distribution at five tilt angles (0° / 15° / 27° / 39° / 50° uptilt) for optimized output across varying ceiling heights and aisle widths. Fixed 5000K daylight CCT on both models. The L34-110 (100W) delivers up to 13,646 lumens for ceiling heights of 12–20 ft; the L34-180 (160W) delivers up to 21,077 lumens for 18–28 ft ceilings. Both UL listed for damp locations and DLC Listed for utility rebate eligibility. 7-step MacAdam Ellipse color consistency. 0–10V dimmable driver standard. Backed by RAB’s 5-year limited warranty.

Performance & Light Output

Fixed 5000K CCT. All values at 5000K; wing tilt redistributes beam pattern rather than reducing total output. L34-110 (100W): 13,534–13,646 lm across all tilt angles | peak 136 lm/W | CRI 85 | input 100.2–100.5W. L34-180 (160W): 20,754–21,077 lm across all tilt angles | peak 133 lm/W | CRI 86 | input 156.6–160.7W. Full tilt angle × wattage performance data available on the RAB L34 spec sheet. Rated life 50,000 hours.

Smart & Control Features

Both L34 models are available with optional controls via suffix ordering — specify at time of order:

• /LC: Lightcloud Controller — wireless group control
• /LCS: Lightcloud Sensor — integrated sensor + wireless control
• /MVS: Occupancy Sensor — microwave-based occupancy detection
• MVSREM: Remote for microwave sensor — sold separately

Standard fixtures ship without controls. 0–10V dimming wiring is standard on all variants.

Electrical

Constant Current, Class 2, Class P driver. 120–277V AC, 50/60 Hz. 0–10V dimming from 100% to 10% minimum. L34-110 input current: 120V / 0.92A | 277V / 0.40A. L34-180 input current: 120V / 1.50A | 277V / 0.65A. Surge protection: 2.5kV. Mercury and UV free, RoHS-compliant. Green Technology.

Construction

Lightweight polycarbonate and ABS (PC/ABS) housing on both models. Adjustable fold-up wings with paracord lens lock. Finish formulated for high durability and long-lasting color. Dimensions: 19-3/4" × 8" × 2-5/8" — both models. Weight: 4.8 lbs (L34-110) | 6.0 lbs (L34-180).

Installation & Mounting

Both models mount via V hooks (included). Optional pendant mounting supported (pendant by others). Set wing tilt angle before final installation using the paracord locking mechanism.

• Mounting: V hooks (included); pendant mount by others
• Sensor Remote: MVSREM — sold separately (for /MVS suffix units)

Certifications & Rebates

Both models UL listed for damp locations. DLC Listed (DLC 5.1) — L34-110: DLC ID PTF2Z78V | L34-180: DLC ID PVWC2J26. Eligible for utility rebate programs through DLC Member Utilities. Verify eligibility at designlights.org. RoHS compliant. BAA-compliant versions available upon request.

Typical Applications

• Warehouses & Distribution Centers: L34-110 for 12–20 ft ceilings; L34-180 for 18–28 ft — adjustable wing angle optimizes aisle and rack illumination for each ceiling height
• Retail & Big-Box Stores: Ultra-economy PC/ABS construction reduces fixture cost on large-footprint projects; CRI 85/86 supports accurate merchandise color rendering
• Light Manufacturing & Assembly: High-efficacy output at an economy price point for production floors requiring cost-effective LED conversion
• Commercial & Office Warehousing: Lightweight construction eases installation in load-sensitive ceiling structures
• Gymnasium & Recreation Facilities: 50° uptilt wing position delivers indirect or supplemental uplighting in high-ceiling venues
• Retrofit Projects: DLC Listed and 0–10V dimmable — both models qualify for utility rebates to offset retrofit investment
