LED Strip Lights Buyer's Guide: Kitchen, Bathroom & Living Room Uses

Verthara sells a lot of LED strip lights, and this LED strip lights buyer's guide exists because the packaging rarely tells you the two things that actually matter: how bright the strip is and whether it's safe for the room you want it in. Get those right and strip lighting is one of the cheapest, most transformative upgrades in a home. Get them wrong and you end up with a dim glow behind the sofa or, worse, a non-waterproof strip failing in a bathroom.

How bright should LED strip lights be?

Brightness is measured in lumens per metre, and it's the spec most strips hide. For task lighting under kitchen cabinets you want 400 to 500 lumens per metre so the worktop is genuinely usable. For accent lighting, behind a TV, under a bed frame, along a shelf, 200 to 300 lumens per metre is plenty. Go brighter for accent and it stops being a soft glow and starts being a light source you notice.

The LED density also matters. A strip with 60 LEDs per metre gives a smooth, continuous line of light. A cheaper 30-per-metre strip shows visible dots, especially through a diffuser. For anything you'll see directly, spend on the higher density.

What do IP ratings mean for LED strips?

The IP rating is the number that keeps a strip safe. It has two digits: the first is dust protection, the second is moisture. For LED strips the second digit is the one that counts.

IP20 strips have no moisture protection and belong in dry rooms only, living rooms, bedrooms, dry kitchen runs. IP65 strips are coated and resist splashes and steam, which makes them right for bathrooms and around sinks. For fully outdoor use, in a garden or on a patio, look for IP67 or IP68. Putting an IP20 strip in a bathroom is a genuine safety risk, not just a durability question.

Bathroom zones and IP ratings

UK bathrooms are split into zones by proximity to water. Zone 1, in and around the bath or shower, needs a minimum of IP65. The rest of the room is safer but steam still travels, so IP65 across the board is the simplest safe choice for bathroom strip lighting.

What colour temperature should you choose?

3000K warm white suits living rooms, bedrooms and most kitchens where you want a cosy feel. 4000K neutral white is crisper and works for bathrooms and functional kitchen task lighting. Some strips are tunable, letting you shift between warm and cool, which is handy if the strip serves more than one mood. RGB and RGBW strips add colour, which is fun for a media room but rarely what you want for everyday light.

How do you power LED strips correctly?

This is where installs go wrong. Every strip needs a driver, or power supply, rated for the total wattage of the run. Add up the watts per metre times the length, then choose a driver with at least 20 percent headroom so it isn't running flat out. A 5-metre strip at 10W per metre draws 50W, so you want a 60W driver.

There's also a practical limit on how long a single run can be before voltage drop dims the far end. For 12V strips that's often around 5 metres. Beyond that you power from both ends or use a higher voltage 24V system. If the last metre of your strip looks dimmer than the first, voltage drop is why.

Which type is right for each room?

Kitchen: IP20 under wall cabinets for dry runs, 400 to 500 lumens per metre, 3000K to 4000K, mounted towards the front edge of the cabinet underside.

Bathroom: IP65 minimum, 4000K, used to backlight a mirror or under a vanity unit for soft night lighting.

Living room: IP20, 200 to 300 lumens per metre, 3000K, behind the TV or along shelving to add depth in the evening without glare.

Common buying mistakes

Ignoring lumens per metre

Buying on price alone gets you a dim strip. Check the lumens per metre and match it to the job, task or accent.

Using the wrong IP rating

An IP20 strip in a bathroom is unsafe. Always use IP65 or higher anywhere near water.

Underrating the power supply

A driver running at its absolute limit gets hot and fails early. Size it with 20 percent headroom over the strip's total wattage.

Running one strip too long

Push a 12V strip past its limit and the end goes dim from voltage drop. Split the run or step up to 24V for long lengths.

Frequently asked questions

Can you put LED strip lights in a bathroom?

Yes, but only with an IP65 or higher rating. Anything less has no moisture protection and is unsafe near a bath or shower.

How many lumens per metre do I need for kitchen worktops?

400 to 500 lumens per metre for under-cabinet task lighting, mounted near the front edge so the light lands on the worktop, not the tiles.

Do LED strips need a special power supply?

Yes. Each strip needs a driver rated for its total wattage with about 20 percent spare capacity. Don't run a strip off a mismatched supply.

Why is the end of my LED strip dimmer than the start?

Voltage drop. The run is too long for the strip's voltage. Power it from both ends, shorten it, or switch to a 24V system for longer lengths.

What's the difference between IP20 and IP65 strips?

IP20 has no moisture protection and is for dry rooms only. IP65 is coated to resist splashes and steam, making it safe for bathrooms, kitchens near sinks, and sheltered outdoor use.

Are 60 LEDs per metre better than 30?

For light you'll see directly, yes. 60 per metre gives a smooth continuous line, while 30 per metre shows visible dots. Use higher density anywhere the strip is on show.
