Home lighting designed for low-voltage recessed installs with a neat, compact profile. Knightsbridge Low Voltage Downlight gives homeowners and installers reassurance through pressed-steel construction and MR16/LED compatibility. Is the compact fitting the right choice for tight ceiling voids and separate transformer requirements?

⚡ At a Glance
  • Light Quality: Dependent on MR16 lamp choice, beam angle and colour temperature vary
  • Best for: Home renovators and electricians fitting low-voltage recessed lighting
  • Not ideal for: Large open-plan rooms needing wide, diffuse illumination

A compact low-voltage downlight with a pressed-steel body and shallow recessed profile. Requires a separate 12V transformer and accepts MR16 and many LED retrofit lamps.


Secure ceiling grip – with spring clip lamp fixing

Spring clip fixings engage behind the cut-out to hold the fitting firmly in place without separate screws. Recommended maximum ceiling thickness for the clips is 15mm.

Secure mounting simplifies retrofits and replacements, keeping the downlight flush against the ceiling. Installers benefit from faster fitting times and reduced need for additional brackets.

Dimmable ambience – with electronic transformer compatibility

Dimmable operation requires an electronic transformer, not supplied with the fitting; a 12V 60VA transformer (T02) is specified for use. Appropriate transformer selection affects dimming smoothness and compatibility with LED MR16 lamps.

Adjustable brightness creates flexible mood lighting when paired with a compatible transformer. Perfect for bathrooms and living spaces where different lighting levels are useful.

Flexible lamp choice – with MR16 lamp holder and LED compatibility

Standard MR16 lamp holder accepts common MR16 halogen lamps and many MR16 LED retrofit bulbs, and the fitting is supplied complete with a bridge and lamp holder. The enclosure is open, allowing straightforward access for wiring.

Choose beam angle and colour temperature to suit each room by swapping MR16 lamps. Retrofit options let users upgrade to LED for lower running power while keeping the same downlight.
