What is a 4ft LED tube light?
A 4ft LED tube light is a linear LED lamp designed to replace traditional fluorescent tubes in many commercial, industrial, and residential fixtures. Measuring approximately 4 feet in length (about 1.2 meters), these tubes deliver bright, energy-efficient illumination with minimal heat. They come in a range of color temperatures and light outputs to suit offices, workshops, retail spaces, and more.
Key benefits include higher luminous efficacy, longer lifespan, instant full brightness, and the absence of mercury compared to fluorescent tubes. For buyers exploring LED retrofit projects, a 4ft LED tube light often serves as a direct replacement option for existing T8 or T12 fluorescent layouts, with choices available for ballast-compatible or ballast-bypass (direct-wire) configurations.

How do 4ft LED tubes differ from other LED tube sizes like 2ft or 8ft?
The main differences are physical length, light output, and fixture compatibility.
- Length: 4ft tubes fit standard 4-foot luminaires and are a common retrofit option in offices and retail displays.
- Light output: Typical 4ft LED tubes range from 1000 to 4000+ lumens depending on wattage and design, making them suitable for general ambient lighting with ample task illumination.
- Fixture compatibility: Some fixtures are designed for 4ft tubes with ballast; others require ballast bypass or direct-wire installations, especially when upgrading from older fluorescent lamps.
What are common wattage and lumen options for 4ft LED tubes?
4ft LED tubes typically span a range to suit different applications. Common options include:
- 18W to 22W tubes delivering roughly 1500 to 2600+ lumens for standard office or shop lighting.
- 25W to 40W equivalents offering 3000 to 5200+ lumens for high-contrast tasks or large open spaces.
What color temperature and CRI options are available for 4ft LED tubes?
Color temperature options typically range from warm white (2700K–3000K) for comfortable, inviting spaces to cool white (4000K–5000K) for task-oriented environments, and daylight (5000K–6500K) for high-contrast visibility. A high CRI (Color Rendering Index) of 80+ or 90+ is common in premium tubes to render colors more accurately in retail, galleries, and medical offices.
When selecting, consider the activity type, the color rendering needs of the space, and any compatibility with existing dimming systems if you plan to dim the tubes.

Are 4ft LED tubes compatible with existing fluorescent fixtures?
Compatibility depends on the fixture and the tube design. Options include:
- Ballast-compatible (plug-and-play): Replaces fluorescent tubes without rewiring; the existing ballast remains in place, and the LED tube is designed to work with that ballast.
- Ballast-bypass (direct-wire): Requires removing or bypassing the old ballast and wiring the fixture for direct power to the tube pins, usually to increase efficiency and lifespan.
- Direct retrofit kits: Some systems use adapters or tombstone replacements to facilitate a safer, easier upgrade.
Do 4ft LED tubes support dimming or smart control?
Many 4ft LED tubes offer dimming, but compatibility depends on the tube and driver. Common options include:
- Triac dimming for standard AC dimmers in commercial spaces.
- 0-10V dimming for finer control in architectural lighting or smart systems.
- PWM or DALI interfaces in advanced installations.
What installation considerations should I know for 4ft LED tubes?
Key considerations include fixture type, mounting height, diffuser compatibility, and electrical safety.
- Confirm whether your fixture is wired for ballast or direct-wire operation.
- Check the tombstone type (shunted vs non-shunted) if you are upgrading from fluorescent tubes, as some LED tubes require one type over the other.
- Ensure power is off during installation, and follow local electrical codes.
- In damp or hazardous environments, select IP-rated tubes designed for those conditions.
What are the reliability, warranty, and safety certifications for 4ft LED tubes?
Reputable 4ft LED tubes come with warranties typically ranging from 3 to 5 years, and sometimes longer for high-end models. Look for third-party safety and performance certifications such as UL or ETL listings, DLC or ENERGY STAR labeling, and RoHS compliance. Certifications indicate adherence to electrical safety standards, quality control, and environmentally friendly materials.
For commercial applications, DLC certification can help maximize energy rebates and utility incentives. Always verify product documentation for specific warranty terms, included driver components, and any conditions related to dimming or ballast compatibility.

How do I choose the right 4ft LED tube light for my space?
Start with the space requirements: room size, ceiling height, and desired brightness. Then consider:
- lumen output and efficacy to meet the required lux levels
- color temperature and CRI to suit task performance and ambience
- fixture compatibility (ballast presence, tombstone types)
- dimming needs and control integration
- environmental conditions (dust, moisture, and impact resistance)
