36 Watt 8 Foot T8 LED Tube | 4320 Lumens | 5000K | 100-277V | Frosted Lens | 25 Pack

Product Overview

This 36 Watt 8 Foot T8 LED Tube is designed for direct replacement of 8-foot fluorescent tubes in retrofit applications. It delivers 4320 lumens at 5000K with a frosted lens for diffused, low-glare output. The tube operates on 100-277V and is suitable for both surface and suspended mounting in linear strip fixtures. Typical installations include office, classroom, and retail retrofits where long runs of linear lighting are required. Sold in packs of 25 for large-scale retrofit projects.

This tube is ETL certified and rebate eligible. It is commonly used in environments where fluorescent tubes are being replaced to improve energy efficiency and reduce maintenance. The 8-foot length and frosted lens provide uniform illumination over desks, aisles, and workspaces.

Core Performance and Output

The tube outputs 4320 lumens at 36 watts, providing an efficacy of 120 lumens per watt. The 5000K color temperature produces a neutral white light suitable for task and general area lighting. The 120° beam angle ensures wide, even coverage in standard linear fixtures. Power factor is greater than 0.90, and total harmonic distortion is less than 18%.

At lower mounting heights, output may be excessive for small rooms or corridors. For high-ceiling retrofits, uniformity may decrease if spacing exceeds typical fixture intervals. This tube is not dimmable and is best suited for on/off control scenarios.

Adjustability and Control Options

This tube is non-dimmable and does not support advanced control protocols. It is designed for simple on/off operation using existing fixture wiring. The 120° beam angle is fixed by the frosted lens and tube geometry.

No field-adjustable color temperature or output settings are available. For applications requiring dimming or tunable white, alternative products should be considered.

Longevity and Reliability

The rated lifespan is 50,000 hours, minimizing relamping frequency in retrofit projects. The tube uses solid-state LED technology with no moving parts or filaments, reducing failure points compared to fluorescent lamps.

Consistent operation is maintained across the full input voltage range of 100-277V. The frosted lens protects the LEDs from dust and minor impacts, supporting long-term reliability in typical commercial environments.

Build Quality and Physical Characteristics

The tube measures 8 feet in length and weighs 3 lbs. The frosted lens provides uniform light diffusion and reduces visible glare. Construction is suitable for standard linear strip and troffer fixtures designed for 8-foot T8 or T12 lamps.

ETL certification confirms compliance with safety and performance standards. The tube is not rated for wet locations or enclosed fixtures with limited airflow. Installation is intended for dry, indoor environments.

Where This Product Fits Best

This tube is intended for indoor retrofit projects where existing 8-foot fluorescent lamps are being replaced. It is most commonly used in commercial, educational, and retail environments that require long, continuous runs of linear lighting. The output and beam angle are suitable for general area and task lighting in open-plan spaces and corridors.

• office lighting retrofit
• classroom lighting retrofit
• retail lighting retrofit
• utility area lighting retrofit
• warehouse aisle lighting retrofit
• healthcare support lighting retrofit
• municipal building retrofit
• corridor lighting retrofit

Best suited for dry, climate-controlled interiors. Not intended for wet locations, high humidity, or environments with frequent temperature cycling.

Installation and Long-Term Use

Installation is direct into compatible 8-foot linear fixtures, either surface-mounted or suspended. The tube is designed for retrofit use and may require bypassing or removing the existing ballast, depending on fixture wiring. Weight and length are manageable for single-person installation, but handling is easier with two people for long runs.

Routine cleaning of the frosted lens is recommended to maintain light output. No relamping is required for the rated service life. The tube is not suitable for use in sealed or enclosed fixtures without ventilation.

How This Fixture Is Commonly Used

Typical mounting heights range from 8 to 14 feet, depending on ceiling type and application. Spacing is usually determined by existing fixture layout, with tubes installed end-to-end for continuous row lighting or in parallel runs for broad area coverage. In office and classroom retrofits, tubes are often spaced to provide uniform illumination over work surfaces.

For higher output requirements, fixture count can be reduced, but this may increase perceived glare in low-ceiling spaces. Spacing and layout should be reviewed to balance light levels and visual comfort.

Safety, Certifications, and Warranty

This tube is ETL certified and meets applicable safety standards for commercial lighting. It is eligible for utility rebates where available. The product is designed for use in dry, indoor locations and is not intended for hazardous or wet environments.

Warranty coverage is provided by the manufacturer for defects in materials and workmanship. Refer to product documentation for warranty terms and claim procedures.

Frequently Asked Questions

Q: What is the recommended mounting height for this 8-foot LED tube?

A: Typical mounting heights are 8 to 14 feet, depending on the application and desired light levels.

Q: Does this tube require ballast removal for installation?

A: In most retrofit scenarios, the existing ballast should be bypassed or removed. Confirm fixture wiring before installation.

Q: Is this tube suitable for use in enclosed or sealed fixtures?

A: This tube is not recommended for fully enclosed fixtures without ventilation, as heat buildup may reduce lifespan.

Q: Can this tube be used with dimming controls?

A: No, this tube is not dimmable and is intended for on/off operation only.

Q: How many tubes are included per pack?

A: Each pack contains 25 tubes.

Q: What is the expected lifespan of this tube?

A: The rated lifespan is 50,000 hours under normal operating conditions.

Q: How should I plan fixture spacing for uniform lighting?

A: Use existing fixture spacing as a starting point. For new layouts, space tubes to achieve target light levels and minimize glare, typically matching the original fluorescent layout.

Application Questions and Clarification

Q: Is this tube appropriate for healthcare support lighting retrofit?

A: Yes, it is suitable for healthcare support areas where 8-foot fluorescent tubes are being replaced in dry, indoor environments.
