Why Switch to LED Tubes?
Converting from traditional fluorescent lighting to LED technology is one of the most impactful upgrades for commercial and industrial facilities. LED tubes eliminate common issues such as flickering, humming ballasts, and slow start-up while delivering instant, consistent illumination.
-
Up to 60% energy savings compared to fluorescent lamps
-
Reduced maintenance costs with 50,000+ hour rated life
-
Improved light distribution and color rendering (CRI)
-
No mercury or hazardous materials
-
Compatible with most existing troffers and strip fixtures
Understanding LED Tube Types
Choosing the correct retrofit method is critical for performance, safety, and long-term reliability. Each LED tube type offers different installation requirements, maintenance considerations, and operational benefits. We stock all major UL-classified options to match your electrical and application needs.
-
Type A (Plug and Play): Operates with existing fluorescent ballasts for the fastest installation and minimal labor.
-
Type B (Ballast Bypass): Requires rewiring to bypass the ballast, delivering maximum reliability and reduced future maintenance.
-
Type C (External Driver): Uses a dedicated LED driver for superior efficiency, control, and advanced dimming capabilities.
-
Dual Mode (Hybrid): Flexible tubes that can operate with a ballast or as a direct-wire solution.
Common Applications for Linear LED Retrofits
LED tubes are the preferred lighting solution for high-use environments where performance, longevity, and energy efficiency are essential.

Office buildings and commercial troffers
-
Warehouses and industrial facilities
-
Retail stores and display lighting
-
Schools, hospitals, and public buildings

Important Technical Considerations
Before ordering, confirm your existing fixture length—commonly 2ft, 4ft, or 8ft, including 3ft and 5ft specialty lengths—and pin configuration such as G13 medium bi-pin, Fa8 single pin, or R17d recessed double contact. Since 1982, Light Bulb Surplus has been a trusted partner for commercial lighting upgrades. Our 33,000 sq ft warehouse supports deep inventory across T8, T5, and T12 LED retrofit solutions to keep projects moving without delays.
Ideal for Large-Scale Facility Upgrades
We specialize in supporting facility managers, contractors, and maintenance teams with bulk quantities, consistent product availability, and knowledgeable technical support. Our LED tubes are selected for durability and dependable performance in demanding environments. Our team can also help you select the correct tube type, color temperature, and wiring method for your specific fixtures, ensuring a smooth transition from legacy fluorescent systems.
FAQ
1) How do I choose the right LED tube to replace my fluorescent?
Start by confirming (1) lamp length (2ft/3ft/4ft/5ft/8ft), (2) pin type (G13, Fa8, R17d), and (3) which retrofit method you want—Type A (plug-and-play), Type B (ballast bypass), Type C (external driver), or Hybrid. If you’re unsure, choosing the retrofit type is usually the biggest decision.
2) What’s the difference between Type A, Type B, and Type C LED tubes?
Type A uses an existing fluorescent ballast (fastest install). Type B bypasses the ballast and rewires the fixture (best long-term reliability). Type C uses an external LED driver (best control/dimming performance). Hybrid tubes support more than one method.
3) How do I know if I need Type A plug-and-play or Type B ballast bypass?
If you want the quickest install and your ballast is in good shape, Type A is often easiest. If you want to eliminate future ballast failures and reduce maintenance, Type B (ballast bypass) is commonly the best long-term choice.
4) Can I use an LED tube in my existing fluorescent fixture without rewiring?
Yes—Type A (plug-and-play) tubes are designed to run on compatible fluorescent ballasts. Compatibility varies by ballast, so confirm ballast compatibility before ordering.
5) How do I tell if my fixture is single-pin (Fa8) or bi-pin (G13)?
A 4ft T8 fixture commonly uses G13 medium bi-pin (two pins on each end). Many 8ft fixtures use Fa8 single-pin (one pin per end) or R17d recessed double contact. The safest approach is to verify the socket type and pin configuration before purchasing.
6) Is ballast bypass (Type B) safe, and who should install it?
Type B requires rewiring the fixture to bypass/remove the ballast and should be installed by a qualified electrician or experienced installer. Once properly wired, Type B setups often reduce long-term maintenance by eliminating ballast-related failures.
7) Will LED tubes stop flickering or humming from my fluorescent lights?
Often yes. Flicker and humming are frequently caused by aging ballasts or lamps. Many upgrades solve these issues, especially when switching to a new compatible ballast (Type A) or removing the ballast entirely (Type B).
8) What color temperature should I choose for offices vs warehouses?
Offices often use 3500K–4000K for comfortable, clean light. Warehouses and industrial areas commonly use 4000K–5000K for brighter visibility. Matching existing lighting and the space’s purpose usually leads to the best results.
9) Do LED tubes work with dimming?
Some do, but dimming depends on the tube type and the fixture’s control gear. Type C (external driver) is most common for controlled dimming systems. Always confirm dimming compatibility before ordering.
10) What details should I verify before ordering LED tubes in bulk?
Verify length, pin type, retrofit method (Type A/B/C/Hybrid), voltage requirements, color temperature, lumen output (brightness), and any special conditions like enclosed fixtures or damp locations. Bulk projects go smoother when these are confirmed up front.
