12 / 15 / 18 / 24 Watt Adjustable T8 LED Tube Light | 1620 to 3240 Lumens | 3500K to 6500K | 100V-277V | 25 Pack

Product Overview

This is a 4 ft T8 LED tube light with adjustable wattage and color temperature. The tube supports four wattage settings: 12, 15, 18, and 24 watts, delivering between 1620 and 3240 lumens depending on the selected wattage. Each tube operates at 135 lumens per watt and is designed for direct replacement of fluorescent strip lighting.

The tube is compatible with 100V-277V input and has a power factor greater than 0.90. It features a frosted lens with a 140-degree beam angle and a CRI of 80+. The product is supplied as a box of 25 tubes.

Color temperature can be set to 3500K, 4000K, 5000K, 5700K, or 6500K. The tube is non-dimmable and rated for a 50,000 hour lifespan. Total carton weight is 16.5 lbs.

Where This Product Fits Best

This T8 LED tube is intended for use in commercial and industrial environments where fluorescent strip fixtures are currently installed. Typical applications include warehouses, manufacturing areas, distribution centers, and utility spaces.

The adjustable wattage and color temperature allow for adaptation to different lighting requirements within the same facility. The tube is suitable for locations with voltage supplies ranging from 100V to 277V.

Use this tube where a frosted lens and wide 140-degree beam angle are needed for even, diffused illumination. The product is appropriate for retrofit projects seeking to standardize on LED technology while maintaining flexibility in output and color.

Performance and Functional Considerations

The tube provides selectable wattage and color temperature, allowing adjustment of light output and appearance after installation. Output ranges from 1620 to 3240 lumens, supporting a variety of lighting levels within the same fixture type.

The 140-degree beam angle delivers broad coverage, minimizing shadowing in open areas. The frosted lens reduces glare and provides uniform light distribution.

With a CRI of 80+, the tube supports accurate color rendering for most commercial and industrial tasks. The power factor above 0.90 and THD below 18% support efficient operation on standard electrical systems.

The tube is non-dimmable and operates at 50/60 Hz. It is designed for use in environments where dimming is not required.

Installation and Long-Term Use

The tube is designed for direct replacement of existing fluorescent strips. It is compatible with 4 ft fixtures and supports input voltages from 100V to 277V.

Color temperature and wattage can be set during installation to match site requirements. The tube's construction supports a 50,000 hour rated lifespan under typical operating conditions.

Each box contains 25 tubes, allowing for consistent upgrades across multiple fixtures. The frosted lens and wide beam angle simplify alignment and reduce the need for precise aiming.

Long-term maintenance is minimized by the tube's rated lifespan and stable electrical characteristics. The product weight per carton is 16.5 lbs, which should be considered for handling and storage.

How This Fixture Is Commonly Used

After installation, the adjustable wattage feature allows you to set the light output to match the needs of each area. This is useful when different spaces require different illumination levels but use the same fixture type.

The selectable color temperature lets you standardize on a preferred light appearance or adjust to match existing lighting. This can be set during installation and left unchanged for consistent operation.

The frosted lens and wide beam angle provide even light distribution, reducing glare and supporting comfortable visibility in work areas. Once installed, the tube operates without the need for ongoing adjustment.

Routine maintenance is limited to periodic cleaning and inspection, as the tube is rated for 50,000 hours of use. No dimming or advanced controls are required for operation.
