Mantra K3 Portable LED IP54 Lantern - Black

K3: A Table Lamp Reimagined for the Outdoors

K3 borrows the silhouette of a classic table lamp, a rounded base, slim stem and tapered shade, and rebuilds it to live outside. In black, the metal body all but disappears once the light is on, leaving a warm ring glowing at the base of the shade around the acrylic diffuser.

Choosing Your Finish

K3 is offered in black and white, and the two sit quite differently on a table. This black version blends into evening shadows and works well against pale stone, light furniture or a bright tablecloth, where it reads as a quiet, almost invisible base for the glow it puts out. If your outdoor furniture and surroundings run darker, the white version tends to show up more clearly by day and can work better as a piece you actually see rather than one that recedes.

How It Works

The light comes from a single integrated 2W LED producing around 155 lumens at a warm 3000K colour temperature, so there is no bulb to change over the lamp's life. A touch control built into the diffuser band lets you dim the light rather than only switching it fully on or off. It runs as a Class III fitting, meaning it operates at a low, extra safe voltage rather than mains voltage at the fitting itself. The body is polycarbonate, chosen for being lightweight enough to move around a table without feeling flimsy.

Where It Works Best

K3 is designed to be portable in the way its name suggests, easy to lift and reposition on a patio table, garden dining set or balcony ledge rather than being fixed in one place. It gives a soft, low level glow suited to eating outside in the evening, more ambient table lighting than a functional work light. It is a natural companion piece next to a Mantra outdoor floor lamp or spike light providing the wider garden lighting, with K3 handling the table itself.

Made By Mantra

Mantra has been designing lighting from its base in Valencia since 2000, with a consistent goal of making design led fittings that do not carry a premium price. K3 is described by Mantra as a rework of its earlier K2 range, reshaped into a more convincing outdoor table lamp rather than an indoor design adapted for use outside. The brand's broader catalogue is built by an in house design team plus named external designers, and its outdoor and technical ranges have continued to expand year on year, including recognition such as a regional ADCV Gold in 2024 for one of its more recent designs. It is not aiming at the luxury end of lighting, but at giving UK gardens and patios something more considered than standard off the shelf outdoor lamps.

Questions People Ask

Can I dim K3?
Yes, there is a touch dimmer built into the diffuser band, so you can adjust the brightness rather than only having a single on or off setting.

Can the bulb be replaced?
No, the LED is integrated into the fitting and is not designed to be swapped out individually, the lamp itself is the light source.

Is it suitable for a covered patio or balcony?
Yes, it is IP54 rated, which suits sheltered or covered outdoor spots, though it is not built for direct, prolonged exposure to heavy rain in the way a higher rated fitting would be.
