K Series GU10 7W 71W-eq 1000lm 100° LED Spotlight Bulb - Warm White

This K Series spotlight bulb takes the familiar GU10 twist-lock cap, so it drops straight into a mains spotlight fitting with a quarter-turn and runs directly on 220-240V AC with no transformer needed. It draws just 7W while putting out 1000 lumens, which is why it stands in for a 71W old-style bulb at a fraction of the running power. The light is a warm white 3000K, and the PAR16 reflector throws a wide 100 degree beam rather than a narrow pool, so the spread is broad and even for a directional lamp. Where US buyers would reach for a BR or PAR-style reflector bulb, this is the GU10 equivalent in spotlight form.

The 100 degree beam makes this a practical choice for ceiling spotlight bars, recessed fittings and track heads where you want general fill rather than a tight accent. It suits kitchens, living rooms, hallways and home offices, and a few of these across a ceiling will wash a room rather than spotlight single objects. Because the beam is wide, the bulbs can sit further apart than narrow-angle spots while still avoiding dark patches. This is an indoor bulb rated IP20, so keep it to dry rooms and out of bathrooms, porches or any damp or exposed position, where the fitting rather than the lamp sets the requirement.

The bulb measures Ø50 by 58 mm and weighs only 30 g, matching the standard GU10 form so it fits existing fittings without clearance issues. Its colour rendering is Ra 80, which keeps everyday interiors looking natural, and the rated life is 15,000 hours at an efficiency of 143 lm/W. The finish is a plain white body and it is non-dimmable, so it should be paired with a standard non-dimming circuit. The K Series runs across several outputs and tones, so matching siblings can be specified for a consistent look through a property.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has a GU10 twist-lock cap, the standard mains spotlight fitting found on ceiling spot bars, recessed downlights and track heads. You push it in and give it a quarter-turn to lock. It runs directly on 220-240V mains, so no separate transformer or driver is required, unlike a low-voltage GU5.3 MR16 lamp.

What old-style bulb does it replace?

The bulb draws 7W of actual power but gives 1000 lumens, which is equivalent to a 71W traditional spotlight bulb. You get the same brightness for a small fraction of the energy. The LED itself only ever draws 7W.

Is it dimmable?

No, this is a non-dimmable bulb. It should be used on a standard non-dimming circuit. Fitting it to a dimmer switch may cause flicker or shorten its life, so a plain on-off switch is recommended.

What is the beam angle and colour like?

The PAR16 reflector gives a wide 100 degree beam, so it spreads light broadly rather than as a tight accent spot. The colour is a warm white 3000K with Ra 80 colour rendering, which keeps living spaces looking natural and comfortable.
