The PAR / GU10 / MR16 category brings together one of the most versatile families of directional LED bulbs and their matching trims. These compact lamps are designed for accent lighting, task lighting and general illumination wherever a focused beam is needed. From retail displays to kitchen pot lights and outdoor landscape fixtures, this family covers a wide range of indoor and outdoor applications.
Bulb types and options
Each base style serves a distinct purpose. GU10 bulbs use a twist-and-lock bi-pin base and run on line voltage (120V), making them a popular direct replacement for halogen spots. MR16 bulbs typically use a GU5.3 pin base and operate on low voltage (12V or 24V AC/DC), requiring a compatible driver or transformer. PAR lamps offer a parabolic reflector for a wide, even spread. You will also find matching swivel trims in round and square profiles and finishes like brushed nickel to complete recessed installations.
Where to use them
These bulbs and trims suit residential spaces such as kitchens, hallways and living rooms, as well as commercial environments like boutiques, galleries, restaurants and offices. Low-voltage MR16 models rated for outdoor fixtures are well suited to landscape and pathway lighting when paired with the correct enclosure.
How to choose
Start with the base type and voltage: confirm whether your fixture is line-voltage (GU10) or low-voltage (MR16 / GU5.3). Next, consider colour temperature, from warm 2700K for cozy settings to neutral 4000K for kitchens and workspaces. Check the beam angle—a narrow beam concentrates light on a focal point, while a wider angle spreads it across a room. For damp or outdoor areas, verify the appropriate IP rating and choose a dimmable model if you want adjustable output.
FAQ
Can I swap a halogen GU10 for an LED GU10? Yes, in most cases the base and shape match directly; confirm dimmer compatibility if needed.
Do MR16 bulbs need a transformer? Yes, low-voltage MR16 lamps require a compatible 12V or 24V driver or transformer.
What colour temperature should I pick? Choose 2700K–3000K for warm ambiance and 4000K for crisp, task-oriented light.
