Description
This GU5.3 LED spotlight bulb is a directional MR16 lamp that gives a focused warm-white light from a compact reflector body. It draws just 7W while producing 570 lumens, replacing an old 35W halogen MR16 of the same fitting. The 120 degree beam angle spreads the light fairly wide for a spotlight, so it suits both accent work and broader downward fill rather than a tight pinpoint. American buyers will know the MR16 reflector shape well; this is the same low-voltage two-pin format, finished in a 3000K warm white tone with Ra 80 colour rendering.
The wide 120 degree beam makes this bulb a practical choice for recessed downlight fittings, track heads and display spots in kitchens, living rooms and hallways. Because the spread is generous, a row of these covers a worktop, shelf run or seating area with even light rather than isolated bright pools, and the warm 3000K tone keeps the mood relaxed in living and dining spaces. It is an indoor lamp only, so keep it to dry rooms and away from bathrooms or any outdoor position; suitability for damp areas depends on the fitting it sits in, not the bulb itself. The reflector measures Ø50 by 53mm, fitting standard MR16 housings.
Built on a Gx5.3 two-pin base, this is a low-voltage lamp rather than a mains one, so it needs a 12V transformer or LED driver to run from a 12V AC or DC supply. It is non-dimmable, drawing 7W at 81 lm/W efficiency, with a rated life of 25,000 hours. The white body keeps it discreet inside a fitting. We stock matching low-voltage and mains LED spotlight bulbs across the range to suit different cap types.

Frequently Asked
Does this bulb need a transformer?
Yes. The Gx5.3 two-pin MR16 cap is a low-voltage fitting, so it runs on a 12V AC or DC supply rather than direct mains. You will need a compatible 12V transformer or LED driver to power it.
What old bulb does it replace?
It replaces a 35W halogen MR16 of the same fitting. The LED itself draws only 7W while giving 570 lumens, so it offers a clear energy saving for the same level of light.
Is this bulb dimmable?
No, this is a non-dimmable lamp. It is designed to run at a fixed output, so it should be used with a standard on/off circuit rather than a dimmer switch.
What does the 120 degree beam angle suit?
The 120 degree beam is fairly wide for a spotlight, spreading light evenly rather than as a tight pinpoint. That makes it well suited to recessed downlights, track heads and general accent lighting where a broader pool of warm light is wanted.
