TekLED 18W 4ft LED T5 Under Cabinet Link Light IP20 With Switch

When you need lighting that covers serious ground without cutting corners, this 4ft 18W T5 LED Under Cabinet Light delivers the goods.

It’s built for longer runs - perfect for lighting up extended worktops, retail shelving, stockrooms, or anywhere you need consistent, reliable light across a wider area.

You’ve got a choice of two colour temperatures depending on the vibe you’re going for. 4000K Day Light is clean and neutral - great for kitchens, offices, and displays where clarity matters. 6000K Cool White is crisp and punchy, ideal for commercial setups like workshops, garages, or spaces that need a bit more brightness and edge.

The on/off switch is built into the unit, so control’s right where you need it. And although it doesn’t include a power lead as standard, it’s designed to work with a separately sold UK 3-pin plug kit, so you can plug it straight into the mains.

At 18W, it’s still energy-efficient, and with its slimline design, it slots in neatly wherever you need it.

Our Other T5 Tube Lights

If the 4ft 18W T5 LED Under Cabinet Light isn't quite the right fit, our T5 LED Tube Lights, a key part of our Commercial Lighting range, offer other options to suit your needs.

The 3ft 14W version is a great choice for slightly smaller spaces like medium-length kitchen counters, retail shelves, or workstations. It provides ample illumination while maintaining a low profile, ensuring your space is well-lit without being overwhelming.

For areas requiring broader coverage, the 5ft 24W model delivers enhanced brightness, making it ideal for larger commercial settings such as workshops, offices, or extensive display areas. Its extended length ensures consistent lighting across wider surfaces.

Both alternatives maintain the same sleek design and built-in switch, ensuring a seamless fit for various applications.

Reasons To Use LEDs

In commercial spaces, lighting has to work as hard as you do. That’s why LED is the go-to.

It’s energy efficient, which means lower bills - especially important when lights are running 8, 10, 12 hours a day (or more). And unlike older tech, LEDs don’t pump out loads of heat, so they’re safer and kinder on your fittings and fixtures.

They’re also way more reliable. No flickering. No buzzing. No random failures when you least expect it. Just clean, consistent light that shows up every day…like it’s supposed to.

LEDs also last a lot longer than traditional tubes or halogens, which means less time up ladders and fewer replacement costs eating into your maintenance budget.

And because they’re slim and low-profile, you can use them almost anywhere - behind counters, under shelves, in tight stockroom corners or across long worktops.

For commercial spaces that need to look good, function well, and keep overheads low, LED lighting just makes sense. Every time.
