Product Overview
This adjustable 4 ft T8 LED tube is designed for fluorescent strip replacement in interior retrofit work. It provides selectable wattage and color temperature settings in a frosted-lens tube format.
The tube operates from 100V to 277V and is supplied as a carton of 30 tubes. Its adjustable output supports lighting updates where existing fixture layouts need different light levels or color temperatures.
Core Performance and Output
Selectable wattage settings are 12W, 15W, 18W, and 24W. Output ranges from 1620 to 3240 lumens, with 135 lumens per watt efficiency.
The 140 degree beam distribution and frosted lens provide broad light distribution. Color temperature is selectable between 3500K, 4000K, 5000K, 5700K, and 6500K, with 80+ CRI.
Higher wattage settings increase delivered output but can be excessive where lower light levels are required. Final output selection should account for mounting height, existing fixture layout, and target light levels.
Adjustability and Control Options
Wattage and color temperature are adjustable at the tube. This allows output and appearance to be set from the available 12W to 24W and 3500K to 6500K selections.
This tube is non-dimming. It operates at 100V-277V, 50/60Hz, with power factor greater than 0.90 and total harmonic distortion below 18%.
Longevity and Reliability
The rated lifespan is 50,000 hours. This supports longer service intervals compared with short-life fluorescent lamp replacement cycles.
Electrical operation is specified across 100V-277V. Consistent settings should be maintained within a fixture group when uniform appearance is required.
Build Quality and Physical Characteristics
This is a 4 ft T8 LED tube with a frosted lens. The frosted optic softens the direct view of the LED source while maintaining a 140 degree beam angle.
The carton contains 30 tubes and weighs 16.5 lb per carton. The tube is intended as a fluorescent strip replacement.
Where This Product Fits Best
This tube fits interior lighting retrofit work where 4 ft fluorescent strip fixtures are being updated with adjustable LED tubes. The selectable output and color settings support spaces with differing light level and visual appearance requirements.
- office lighting retrofit
- classroom lighting retrofit
- retail lighting retrofit
- utility area lighting retrofit
- corridor lighting retrofit
- municipal building retrofit
- healthcare support lighting retrofit
The 4 ft tube format, frosted lens, and broad beam angle suit linear fixture layouts. Settings should be coordinated across each retrofit area to avoid mixed output or color temperature within the same visual field.
Installation and Long-Term Use
Confirm the existing fluorescent strip fixture configuration before installation. The supplied product data identifies this tube as a fluorescent strip replacement but does not establish ballast compatibility or wiring requirements.
Mounting height affects the light level delivered at the work plane. Existing fixture spacing, selected wattage, and selected color temperature should be reviewed before setting all tubes in an area.
How This Fixture Is Commonly Used
In office lighting retrofit, classroom lighting retrofit, and corridor lighting retrofit work, tubes are typically set consistently across a connected fixture layout. Matching wattage and color temperature settings helps maintain a uniform appearance along the installed run.
For utility area lighting retrofit, retail lighting retrofit, municipal building retrofit, and healthcare support lighting retrofit, the selected setting should reflect mounting height and required light level. Higher output can reduce the need for additional light from the existing layout, but it may create more light than needed in lower-mounted fixtures.
Safety, Certifications, and Warranty
This T8 LED tube is ETL certified and rebate eligible.
Warranty terms are not stated in the supplied product data.
