18 Watt 4 Foot T8 LED Tube | 2160 Lumens | 5000K | 100-277V | Clear Lens | 25 Pack

Product Overview

This 18 Watt 4 Foot T8 LED tube delivers 2160 lumens at 5000K color temperature with a clear lens. The tube operates on 100-277V input and achieves 120 lumens per watt efficiency. It serves as a direct replacement for 32 Watt fluorescent tubes.

The tube supports both single-ended and double-ended power wiring configurations. Fluorescent ballast removal is required for installation. This product is sold in boxes of 25 tubes.

Where This Product Fits Best

This tube fits standard 4-foot T8 fixtures where fluorescent lamps are being replaced. The 5000K color temperature produces a bright, daylight-quality output suited for task-heavy environments and spaces where visual clarity matters.

The 100-277V operating range allows use across common commercial and industrial electrical systems. The clear lens provides direct light output with a 140-degree beam angle.

Performance and Functional Considerations

At 18 watts, this tube draws significantly less power than the 32 watt fluorescent it replaces while producing 2160 lumens. The 120 lumens per watt efficacy reflects current LED tube performance standards. CRI is rated at 80+.

The tube is not dimmable. Power factor is rated at .95 with total harmonic distortion below 15%. Operating frequency compatibility covers both 50Hz and 60Hz electrical systems. Rated lifespan is 50,000 hours.

Installation and Long-Term Use

Installation requires bypassing or removing the existing fluorescent ballast. The tube accepts either single-ended or double-ended wiring, allowing the installer to choose based on existing wiring conditions or fixture design. Both configurations use the same tube.

Each tube weighs 1 pound. The 50,000-hour rated lifespan reduces relamping frequency compared to fluorescent tubes in the same fixtures.

How This Fixture Is Commonly Used

Facilities replacing fluorescent tubes in troffer fixtures, strip lights, or wraparound fixtures use these tubes to maintain existing fixture infrastructure while switching to LED. The wiring flexibility means electricians can adapt to different fixture configurations without needing separate tube types.

The 25-pack quantity suits buildings with multiple fixtures requiring relamping at once. The 5000K output is typical in warehouses, manufacturing floors, retail back-of-house areas, and other spaces where bright, neutral white light supports visibility and task performance.
