LED T8 Tube Lights for Commercial Retrofit Projects

STARLAKE supplies LED T8 tube lights for commercial, institutional, retail, and industrial lighting projects, including Type B direct-wire, Type A+B hybrid, and integrated T8 solutions.

The current range includes multiple lengths, wattages, lumen packages, CCT options, and commercial input voltages for offices, schools, supermarkets, warehouses, workshops, and other linear-lighting applications.

A successful fluorescent retrofit requires more than matching tube length and wattage. Ballast and wiring conditions, input voltage, fixture optics, distribution, and required illuminance all influence the installed result.

STARLAKE supports lighting brands, distributors, contractors, importers, and project buyers with product selection, OEM/ODM development, manufacturing, quality control, and North American supply support.

Choose the Right LED T8 Tube Configuration

Start with the existing electrical and fixture conditions.

Type B for Ballast-Bypass Retrofits

Type B tubes operate from line voltage after the fluorescent ballast is removed or bypassed.

Removing the ballast eliminates one system component and can reduce future ballast-related maintenance. This approach can suit fixtures with aging ballasts, projects already scheduled for rewiring, or programs standardizing around direct-wire LED operation.

STARLAKE’s supplied Type B range includes models supporting commercial input configurations such as AC120–277V and AC120–347V, depending on the selected model.

Type A+B for Flexible Retrofit Programs

Type A+B tubes provide greater flexibility for distributors and multi-site programs where existing fixture conditions are not identical.

The approved operating method and ballast compatibility must still be confirmed for the selected model.

Physical fit does not establish electrical compatibility.

Integrated T8 for New Linear Lighting

Where retaining the existing fluorescent fixture is unnecessary, an integrated T8 provides a more self-contained linear-lighting solution.

This can suit new installations or retrofits where aging housings, sockets, wiring, or other fixture components make lamp-only replacement less practical.

How to Choose an LED T8 Tube for Fluorescent Retrofit

A practical selection sequence is:

Existing Lamp & Fixture → Ballast / Wiring → Required Illuminance → Distribution → Required Lumens → T8 Configuration

Fluorescent and LED tubes can produce different installed results even at similar lumen levels.

Traditional fluorescent lamps emit broadly around the tube. LED sources are more directional, so the existing reflector, louver, lens, tube position, mounting height, and LED optical distribution can change how much light reaches the target area.

For retrofit evaluation:

Electrical Compatibility + Fixture Optics + LED Distribution → Installed Lighting Performance

Watts and lumens remain useful product specifications, but the retrofit should ultimately satisfy the required illuminance and distribution.

Optical Compatibility Matters as Much as Physical Fit

Existing fluorescent luminaires were designed around the emission characteristics of fluorescent tubes.

Replacing that source with a directional LED tube changes how light interacts with the fixture’s reflector, lens, diffuser, or louver.

Evaluate:

• Work-plane illuminance

• Uniformity between fixtures

• Perceived glare

• Distribution through existing lenses or louvers

• Fixture spacing

• Light delivered to desks, shelves, aisles, or floors

Offices and classrooms may place greater emphasis on diffusion and visual comfort, while warehouses, workshops, and utility areas may prioritize useful illumination at the target plane.

Higher lumen output cannot by itself correct unsuitable optical distribution.

For this reason, evaluating the LED tube inside the actual fixture provides more useful retrofit information than comparing bare-lamp specifications alone.

LED T8 Retrofit Compatibility Checklist

A replacement tube can physically fit an existing fixture and still be unsuitable.

Think of compatibility in three layers:

Physical Fit → Electrical Compatibility → Optical Compatibility

Ballast and Wiring

Determine whether the project will retain, bypass, or remove the fluorescent ballast.

For direct-wire installations, follow the approved input and wiring method for the selected tube. Where an existing ballast remains in the system, compatibility should be verified for the specific product.

Input Voltage

Confirm the actual supply voltage before ordering.

STARLAKE’s supplied T8 portfolio includes models supporting commercial input ranges such as AC120–277V and AC120–347V, depending on product.

Fixture Optics

Inspect the existing reflector, louver, diffuser, or lens because these components can substantially change the distribution produced by the replacement tube.

CCT

The supplied STARLAKE range includes CCT options such as 3500K, 4000K, 5000K, and 6500K, with selectable-CCT configurations available on specified models.

CCT should follow the visual task, surrounding environment, adjacent lighting, and project specification.

Controls

If the existing system uses dimming, occupancy sensors, or other controls, verify compatibility with the selected tube, driver architecture, and electrical configuration.

Should You Retrofit the Tube or Replace the Fixture?

Not every fluorescent installation is a good candidate for lamp-only replacement.

The existing fixture condition, installation labor, optical requirements, controls, and long-term maintenance strategy should guide the decision.

Keeping a serviceable fixture can reduce project scope. Rebuilding deteriorated fluorescent hardware, however, can add enough labor and future maintenance exposure that complete replacement becomes more practical.

Compare:

Product Cost + Installation Labor + Fixture Condition + Required Performance + Controls + Future Maintenance

rather than lamp price alone.

Commercial T8 Options for Different Projects

STARLAKE’s supplied LED T8 portfolio includes 2FT, 3FT, 4FT, and 8FT configurations, with wattage, lumen output, CCT, voltage, and electrical architecture varying by product family.

These configurations support offices, schools, retail stores, supermarkets, warehouses, stockrooms, workshops, and general commercial spaces.

Selection should follow the actual fixture, electrical system, and lighting requirement rather than standardizing one T8 configuration across every environment.

Test Before Volume Deployment

For projects involving hundreds or thousands of tubes, a small mock-up can identify compatibility problems before volume installation.

Existing fluorescent fixtures can vary in ballast type, socket arrangement, reflector design, lens geometry, wiring condition, and age, including across different buildings within the same program.

Use:

Sample → Electrical Compatibility → Fixture Fit → Distribution → Illuminance & Glare → CCT Appearance → Volume Approval

Before rollout, verify:

• Tube and socket fit

• Ballast or direct-wire operation

• Supply voltage

• Distribution within the existing fixture

• Illuminance at the relevant target plane

• Perceived glare

• CCT appearance

• Existing controls, where applicable

For multi-site programs, test representative fixture types rather than assuming every location has identical legacy hardware.

Why Source LED T8 Tube Lights From STARLAKE?

Large T8 retrofit and distribution programs require repeatable configurations, manufacturing consistency, engineering support, compliance coordination, and supply continuity.

Engineering and OEM/ODM Support

STARLAKE has 50+ engineers with capabilities spanning power-supply design, thermal management, optics, mechanical development, controls, and LED integration.

For lighting brands and distributors, OEM/ODM requirements can include electrical configurations, product specifications, CCT options, labeling, packaging, and other program-specific requirements subject to engineering review.

Manufacturing and Quality Control

Founded in 2010, STARLAKE operates approximately 280,000 sq.ft of production space with manufacturing facilities in Shenzhen and Cambodia.

A team of 30+ QC professionals supports manufacturing quality control. Bulk orders undergo an 8-hour aging test, while newly developed products undergo validation that includes 30 days of continuous high-temperature testing.

These procedures support early-stage manufacturing, electrical, component, and thermal screening rather than serving as a direct substitute for product-specific lifetime or lumen-maintenance data.

Compliance and North American Supply

STARLAKE works with product requirements including UL, DLC, and FCC, supported by an ISO 9001 quality-management system.

Certification availability varies by model, configuration, and target market. Required safety certification, DLC qualification, rebate documentation, or other compliance requirements should therefore be confirmed for the exact product before ordering.

STARLAKE also maintains warehouse support in Ohio and California for applicable North American inventory and supply programs.

What Do We Need for a T8 Retrofit Recommendation?

An initial T8 evaluation can begin with a small amount of existing-system information.

Provide:

• Existing tube or fixture photo

• Ballast photo or model, if available

• Supply voltage

• Project quantity

• Project location

Where available, also provide CCT requirements, target illuminance, controls, certifications, and OEM, private-label, or packaging requirements.

This information helps determine the appropriate T8 architecture and whether sample validation should precede volume deployment.

Plan Your LED T8 Retrofit With STARLAKE

The appropriate LED T8 tube must fit more than the fluorescent fixture’s physical dimensions.

A useful retrofit sequence is:

Existing Fixture → Electrical Architecture → Optical Compatibility → Required Lighting Performance → T8 Configuration → Sample Validation

STARLAKE provides Type B, Type A+B, and integrated LED T8 solutions supported by engineering, OEM/ODM development, manufacturing, quality control, compliance coordination, and North American supply infrastructure.
