Mantra K3 Portable LED IP54 Lantern - White

K3 in White: A Bright Companion for Outdoor Tables

K3 takes the familiar profile of an indoor table lamp, rounded base, slim stem, tapered shade, and builds it to handle life outside. In white, the body reads as a clean, almost architectural object during the day, with a warm ring of light glowing from the acrylic diffuser once evening comes in.

Choosing Your Finish

K3 comes in white and black. This white version tends to stand out more clearly against darker outdoor furniture, decking or evening greenery, working as a lamp you notice on the table rather than one that blends away. If your setting runs paler, with light stone, pale furniture or a bright table setting, the black version of K3 will generally sit back more quietly and let the glow do the talking instead of the body of the lamp itself.

How It Works

Light comes from a single integrated 2W LED giving around 155 lumens at a warm 3000K colour temperature, so there is no separate bulb to source or replace. A touch control in the diffuser band adjusts brightness rather than offering only a simple on and off switch. K3 is built as a Class III fitting, running at a low, extra safe voltage rather than mains voltage at the lamp itself, and the polycarbonate body keeps it light enough to lift and move without feeling insubstantial.

Where It Works Best

True to its portable design, K3 is meant to be picked up and moved around a patio table, garden dining set or balcony rather than fixed permanently in place. It gives a gentle, ambient glow better suited to evening dining or relaxed outdoor seating than to task lighting. Pairing it with a Mantra spike light or floor lamp for the wider garden gives K3 a clear job, lighting the table itself while other fittings handle borders and paths.

Made By Mantra

Mantra has designed lighting from Valencia since 2000, built around the idea that design led fittings should not automatically carry a designer price tag. Mantra positions K3 as a successor to its earlier K2 range, rethought specifically as an outdoor piece rather than an indoor lamp pressed into outdoor service. Beyond individual ranges, the brand runs an in house design team alongside named external designers and has picked up external recognition including a regional ADCV Gold in 2024, while its wider catalogue of decorative, technical and outdoor lighting continues to grow each year. Mantra's strength is design conscious, accessible lighting for ordinary UK homes and gardens, rather than a claim to sit alongside the very top end of the lighting industry.

Questions People Ask

Is the white finish easily marked or discoloured outdoors?
The body is polycarbonate rather than fabric or painted metal, chosen for coping with outdoor conditions, though like any pale outdoor finish it is worth a wipe down as part of general garden furniture care.

Does it have a dimmer?
Yes, a touch dimmer is built into the diffuser band, letting you set the brightness rather than only switching it fully on or off.

How does the white version compare to the black K3?
They share the same size, output and features, the difference is purely how each sits visually against your furniture and surroundings.
