21 Watt 14 Inch LED Flush Mounted Ceiling Light | 1470 Lumens | 3000K / 4000K / 5000K Adjustable | 100-277V | Emergency Battery Backup

Product Overview

This 21 Watt 14 Inch LED Flush Mounted Ceiling Light is a surface-mounted fixture designed for general-purpose commercial and utility ceiling lighting. It delivers consistent, low-glare illumination suitable for corridors, hallways, and low ceiling environments. The fixture supports selectable color temperature (3000K, 4000K, or 5000K) and operates on 100-277V, making it compatible with a wide range of building electrical systems.

The acrylic lens and stainless steel housing provide a durable, easy-to-clean solution for spaces with regular foot traffic and routine maintenance. Emergency battery backup is integrated for code compliance and egress support. Typical mounting heights are 8 to 12 feet in commercial interiors, including utility spaces and back-of-house areas.

Core Performance and Output

This fixture produces 1470 lumens at 21 watts, with an efficacy of 70 lumens per watt. The 120° beam angle provides broad, even coverage for small to mid-sized rooms and corridors. Triac dimming is supported for basic light level adjustment. Color temperature can be set to 3000K, 4000K, or 5000K during installation to match ambient requirements.

Output is appropriate for low to standard ceiling heights. At mounting heights above 12 feet, light levels may be insufficient for task-intensive areas. Excessive output is unlikely in typical corridor or utility space installations.

Adjustability and Control Options

The fixture includes a field-selectable color temperature switch, allowing adjustment between 3000K, 4000K, and 5000K. This supports adaptation to changing tenant or facility requirements without replacing the fixture. Triac dimming is compatible with standard wall dimmers for basic control.

No advanced controls or networked options are integrated. The emergency battery backup provides automatic operation during power loss, supporting egress requirements.

Longevity and Reliability

The fixture is rated for 50,000 hours of operation at L70. The solid-state LED array and integrated driver are designed for continuous use in commercial environments. The stainless steel housing and acrylic lens resist corrosion and impact from routine cleaning or incidental contact.

Operating temperature range is -22°F to 113°F, suitable for conditioned and unconditioned interior spaces. Emergency battery backup is factory-integrated for reliable code compliance.

Build Quality and Physical Characteristics

The housing is constructed from stainless steel with a brushed nickel or oil rubbed bronze finish. The acrylic lens provides uniform light diffusion and is resistant to yellowing. Fixture dimensions are 14 inches in diameter and 4.5 inches in height, with a total weight of 3.75 lbs.

Surface mounting hardware is included. The fixture is designed for flush installation on standard ceiling junction boxes. All components are accessible for routine inspection and maintenance.

Where This Product Fits Best

This fixture is intended for commercial and utility environments where surface-mounted, low-profile ceiling lighting is required. It is commonly installed in corridors, utility spaces, and low ceiling areas where uniform, low-glare illumination is needed.

• commercial ceiling lighting
• corridor lighting
• utility space lighting
• low ceiling lighting
• storage room lighting
• back-of-house lighting
• maintenance area lighting
• small retail lighting

The fixture is suitable for dry and damp locations within the stated temperature range. Not intended for exterior or wet location use.

Installation and Long-Term Use

Surface mounting is direct to standard ceiling junction boxes. The fixture?s low profile allows installation in areas with limited overhead clearance. Color temperature selection and emergency battery backup are set during installation. Routine cleaning can be performed with non-abrasive materials.

Long-term maintenance is limited to periodic inspection of the lens and housing. Emergency battery backup should be tested per local code requirements. No relamping or driver replacement is expected within the rated lifespan.

How This Fixture Is Commonly Used

Typical mounting heights are 8 to 12 feet, with fixtures spaced to provide continuous, overlapping coverage in corridors or open utility spaces. In storage rooms or maintenance areas, one fixture is often sufficient for spaces up to 120 square feet. For longer corridors, fixtures are installed at intervals of 8 to 12 feet, depending on required light levels and ceiling height.

Spacing and fixture count may be reduced when higher color temperature or maximum lumen output is selected. Lower color temperature settings may require closer spacing for uniformity.

Safety, Certifications, and Warranty

This fixture is ETL certified. It is eligible for utility rebates where applicable. The product includes a 5-year warranty covering manufacturing defects and LED performance. Emergency battery backup is integrated and meets standard egress requirements.

No additional safety certifications are required for typical commercial interior use. All components are rated for the stated operating temperature and voltage range.
