Ballast failure is one of the most common reasons fluorescent fixtures stop working. Learning how to bypass a ballast allows you to upgrade to LED lighting permanently and reduce future maintenance.

This guide explains the process clearly, safely, and correctly.

Why Bypass a Ballast?

  • Ballasts fail before LEDs

  • Overheating risk

  • Flickering lights

  • Reduced efficiency

Tools You’ll Need

  • Voltage tester

  • Wire nuts

  • Wire cutters

  • LED ballast bypass tubes

Step-by-Step Ballast Bypass Process

  1. Turn off power at breaker

  2. Remove fluorescent tube

  3. Open fixture housing

  4. Disconnect ballast wires

  5. Connect line voltage directly to sockets

  6. Install LED tube

  7. Restore power and test

Single-Ended vs Double-Ended LED Tubes

Light inside a room sets the tone for how people feel and how they use the space. When the glow is dim, tasks become harder.

They are not just replacements for older lights. They bring reliability, savings, and comfort that fit into modern living.

That glow doesn’t come from street lamps or floodlights—it comes from fixtures mounted right on the wall. These are LED wall pack lights , and they’ve quietly become the unsung heroes of outdoor lighting. Where You Notice Them Without Realizing Most people don’t think about wall pack lights until they walk past one. You see them on: School buildings Office exteriors Warehouses and factories Small shops with late-night schedules Apartment entryways They work silently, switching on as the day fades, giving you visibility where you need it most. What Makes Them Different Unlike pole lights or floodlights, wall packs stay close to the structure. This design means: Light spills directly onto walkways, doorways, or loading docks. The beam spreads wide enough to cover entrances without wasting energy on areas too far away. They blend into the...
