LED Low Bay Lights

10 Important Factors to Consider When Purchasing a Low Bay LED Light

When your facility has lower ceilings under 20 feet, low bay lighting fixtures deliver the optimal balance of energy efficiency and lighting performance. After 17 years of designing commercial lighting systems, we've seen these fixtures transform aircraft hangars, workshops, retail stores, and small warehouses with consistent, high-quality illumination.

1. Ceiling Height and Lumen Output

Matching lumen output to ceiling height ensures optimal light distribution without energy waste. Based on thousands of installations, here's what we typically recommend:

• 8-12 ft ceilings: Choose fixtures with 3,000-7,000 lumens
• 12-20 ft ceilings: Choose fixtures with 8,000-15,000 lumens
• Above 20 ft ceilings: Check out our selection of high bay lighting

A workshop with 10-foot ceilings running 5,000 lumen fixtures creates that sweet spot where visibility is excellent but workers aren't squinting from excessive brightness. Powerful high bay lights are unnecessary for this application, as they are designed for high ceilings.

2. Fixture Type: Linear vs. UFO

Linear Low Bay Lights:

• Warehouse aisles benefit from linear fixtures because the elongated design matches the space geometry perfectly
• Broad, even distribution covers more ground with fewer fixtures
• Direct replacement for aging fluorescent systems without rewiring

UFO Low Bay Lights:

• Round footprint concentrates light in large spaces where pinpoint accuracy matters
• IP65 waterproof and IK08 impact-rated construction
• Metal halide retrofit projects favor UFO designs for mounting compatibility

3. Color Temperature

Color temperature affects both productivity and ambiance in measurable ways:

• 4000K (neutral white): Retail environments and office areas benefit from this balanced tone that feels inviting yet professional
• 5000K (daylight): Manufacturing facilities and precision work areas see improved accuracy and reduced errors under crisp daylight simulation

4. Mounting Options

Installation flexibility depends on your mounting choice:

• Hooks and chains: Shop environments benefit from adjustable positioning to fine-tune task lighting without permanent modifications
• Surface mounts: Low ceiling installations use direct mounting for maximum headroom clearance
• Pendant mounts: Junction box connections work when electrical infrastructure is already in place

5. Beam Angle

We recommend beam angle selection based on your specific layout:

• Narrow angles (60°-90°): Workstations and assembly lines need focused beam illumination to eliminate shadows on detailed tasks
• Wide angles (120°): General area lighting requires broad coverage, making 120° beam spread our standard recommendation for most low bay applications

6. Energy Efficiency

• Quality fixtures deliver higher lumen output ensuring maximum light output for every dollar spent on energy usage
• Customers regularly report 75% energy reduction when switching from fluorescent or metal halide to LED low bay lighting

7. Adjustability

Advanced fixtures offer selectable wattage and color temperature through simple DIP switches. This post-installation flexibility lets you dial in the perfect lighting level without ordering multiple fixture types or making expensive changes later.

8. Ingress Protection (IP) Ratings

Environmental conditions determine the protection level you need:

• Dry indoor spaces: IP40-rated fixtures handle normal dust and debris
• Dusty or damp spaces: IP65-rated construction prevents moisture intrusion and particle buildup
• Food processing or cleanroom environments: NSF certification meets strict sanitary requirements for food-safe applications

9. Motion Sensors and Controls

Smart controls multiply your energy savings beyond the LED conversion alone:

• Motion Sensors: Unoccupied areas automatically reduce to 20% power or switch off completely
• 1-10V Dimming: Task-specific brightness adjustment can cut power consumption by another 30-50% during low-activity periods

10. Certifications and Warranty

• Essential certifications include ETL Listed, cULus Listed, and DLC Premium approval for safety compliance and rebate eligibility
• Our fixtures include comprehensive 5-year warranty coverage with USA-based support for peace of mind

Common Mistakes and How to Avoid Them

Seen too many low bay projects go sideways because people skip basic planning steps. Most problems come down to not matching the fixture specs to their actual ceiling heights and work requirements.

• Using high bay fixtures in spaces under 20 feet creates nasty glare problems. Stick with low bay rated fixtures that distribute light properly at your ceiling height.
• Mixing 4000K and 5000K fixtures in the same area looks terrible and causes worker complaints. Pick one color temperature and use it throughout each zone.
• Hanging chain mount fixtures too low blocks overhead equipment movement. Keep minimum 8 feet clearance for forklifts and cranes or you'll have damaged fixtures.
• Not checking circuit capacity before ordering causes expensive delays when your electrical can't handle the new load. Verify amp draw against existing breaker sizes first.
• Skipping IP65 rating in dusty shops leads to early failures when dust buildup overheats the drivers. Manufacturing environments need sealed housings period.
• Ordering narrow beam angles for general lighting creates dark spots between fixtures that violate safety codes. Use 120 degree spread unless you need task specific illumination.
• Trying to retrofit fluorescent strips instead of replacing the whole fixture gives you uneven light distribution and mediocre performance.
• Installing fixtures without motion sensors in low traffic areas wastes the biggest energy savings opportunity after the LED conversion itself.
