Product overview

Upgrade to high‑efficiency lighting with the Wesome Lighting 21‑Inch F13T5/CW LED replacement bulbs. These tubes are designed to drop into fixtures that previously used fluorescent tubes, offering a modern LED alternative with steady, crisp light and reliable performance. The 4100K cool white tone is well suited for workspaces and task lighting, helping colors appear true and details to stand out without glare.

Key specifications help you compare at a glance. The bulbs run at 9 watts, emit about 950 lumens, and offer a color rendering index (CRI) of 80+. They use a G5 bi-pin base and are ballast-compatible, meaning they can replace your existing fluorescent tubes in many electronic ballast fixtures.

  • Wattage: 9 watts
  • CCT: 4100K cool white
  • Light output: ~950 lumens

Energy efficiency and longevity

Compared with traditional fluorescent tubes, these replacements typically reduce heat output and energy use. With a long service life—roughly 30,000 hours—your maintenance needs may be fewer over the years, while keeping spaces evenly lit and productive.

Easy installation and reliability

Installation is straightforward: each tube has pins at both ends that drop into the socket and twist into place. A simple plug-and-play approach means light can come on quickly in kitchens, counters, offices, and cabinets. Before installing, verify that your ballast is functional at both ends.

Practical applications

These T5 replacement tubes are well suited for a variety of settings, from busy office work zones to kitchen counters and cabinet displays. They offer a modern, energy-conscious lighting option that supports clean, consistent illumination across surfaces used daily.

What this upgrade offers

  • Potential energy savings by replacing fluorescent tubes
