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.

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

For a successful fluorescent retrofit, matching tube length and wattage isn’t enough. Ballast and wiring conditions, input voltage, fixture optics, light 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 system. Different T8 configurations solve different retrofit and maintenance requirements.

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 an additional system component and can reduce future ballast-related maintenance. This approach is practical when existing ballasts are aging, fixtures are already scheduled for rewiring, or the project is 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 projects where existing fixture conditions aren’t identical.

The approved operating method and ballast compatibility should always be confirmed for the selected model. Physical fit doesn’t guarantee electrical compatibility.

Integrated T8 for New Linear Lighting

When retaining the original fluorescent fixture isn’t necessary, an integrated T8 offers a more self-contained linear lighting solution.

This approach can suit new installations or retrofit projects 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

Don’t select an LED tube by wattage alone.

A better decision sequence is:

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

Lumens measure the total visible light produced by a lamp. Illuminance, measured in lux or foot-candles, describes how much of that light reaches a desk, shelf, aisle, floor, or other target surface.

This distinction matters because fluorescent and LED tubes don’t distribute light in the same way.

Traditional fluorescent tubes behave as broad, diffuse light sources. LEDs are smaller, discrete, and naturally more directional. An LED tube can therefore have similar total lumen output while producing a different lighting result inside the same fixture.

Existing reflectors, louvers, lenses, mounting height, tube position, and optical distribution can all affect useful illumination.

Watts and lumens are starting specifications. Installed illuminance and distribution determine whether the retrofit actually works.

Optical Compatibility Matters as Much as Physical Fit

Most existing fluorescent luminaires were designed around the broad emission pattern of a linear fluorescent lamp.

Replacing that source with a directional LED tube changes how light interacts with the reflector, lens, or louver. Poor optical compatibility can create excessive brightness in one area while reducing useful illumination elsewhere.

Evaluate:

• Work-plane illuminance

• Uniformity between fixtures

• Perceived glare

• Distribution behind existing lenses or louvers

• Fixture spacing

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

For offices and classrooms, diffusion and visual comfort may deserve greater emphasis. Warehouses, workshops, and utility areas may prioritize useful output at the target plane.

Higher lumen output alone cannot correct unsuitable light distribution.

This is why evaluating an LED tube inside the actual fixture is more useful than comparing bare-lamp specifications alone.

LED T8 Retrofit Compatibility Checklist

A tube can physically fit into an existing fixture and still be the wrong retrofit.

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 operation with an existing ballast is required, compatibility should be verified rather than assumed.

Input Voltage

Confirm the actual supply voltage before ordering.

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

Fixture Optics

Check the existing reflector, louver, diffuser, or lens. These components can substantially change the distribution produced by the replacement tube.

CCT

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

Neutral options such as 3500K and 4000K can suit many offices, classrooms, retail spaces, and general commercial interiors. Cooler options may be selected for certain warehouse, workshop, or utility applications.

Controls

If the existing installation uses dimming, occupancy sensors, or other controls, confirm compatibility with the selected tube and electrical configuration before specification.

Should You Retrofit the Tube or Replace the Fixture?

Not every fluorescent installation should receive a replacement tube.

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

Keeping a serviceable fixture can reduce project scope. Rebuilding a deteriorated fluorescent fixture, however, may add enough labor and maintenance risk that complete replacement becomes the more practical option.

Compare product cost, installation labor, fixture condition, controls, required lighting performance, and future maintenance rather than lamp price alone.

Commercial T8 Options for Different Projects

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

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

For project selection, match the tube to the actual fixture and lighting requirement rather than standardizing on one wattage or configuration for every environment.

Test Before Volume Deployment

When hundreds or thousands of tubes are involved, a small mock-up can prevent a small compatibility issue from becoming a project-wide problem.

Fluorescent fixtures vary in ballast type, socket arrangement, reflector design, lens geometry, wiring condition, and age. A sample installation allows these variables to be evaluated under real project conditions.

Use a simple validation sequence:

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

Before approving a large rollout, verify:

• Tube and socket fit

• Ballast or direct-wire operation

• Supply voltage

• Light distribution

• Illuminance at the relevant work plane

• Perceived glare

• CCT appearance

• Existing controls where applicable

For multi-site programs, test representative fixture types rather than assuming every building has the same installation.

Why Source LED T8 Tube Lights From STARLAKE?

A commercial T8 program needs more than an acceptable first sample. Engineering support, production consistency, customization, compliance, and supply continuity become increasingly important as volume grows.

Engineering and OEM/ODM Support

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

For lighting brands and distributors, OEM/ODM support can cover electrical configurations, product specifications, CCT options, labeling, packaging, and other project-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 production consistency. Bulk orders undergo an 8-hour aging test, while newly developed products undergo a validation process that includes 30 days of continuous 24/7 high-temperature testing.

These processes help identify manufacturing and early-stage reliability issues. They don’t replace 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. If a project requires specific safety certification, DLC qualification, rebate eligibility, or other documentation, confirm it before selecting the final model.

For North American customers, STARLAKE also maintains an Ohio/California warehouse, complementing its manufacturing operations in Asia and supporting regional inventory and supply planning for applicable products.

What Do We Need for a T8 Retrofit Recommendation?

You don’t need a complete lighting specification to start a conversation.

For an initial recommendation, send us:

• Existing tube or fixture photo

• Ballast photo or model if available

• Supply voltage

• Project quantity

• Project location

If available, also provide the required CCT, target illuminance, controls, certifications, and any OEM, private-label, or packaging requirements.

From there, STARLAKE can help determine the appropriate T8 configuration and whether sample validation is recommended before volume ordering.
