Start with the fitting already in the ceiling, then decide on colour, dimming and the room where the light will be used. This guide gives Pretoria shoppers a quicker way to compare verified downlight options before ordering or speaking to an electrician.
For a broad range of GU10 and related LED downlights, browse the LED Down Lights & GU10 Downlights collection. If you are replacing an existing fitting, keep the old lamp, holder and cut-out details nearby while you compare.

The right downlight depends less on a generic wattage claim and more on the existing fitting and the way the room is used. Check these three points first.

Warm white suits relaxed living areas and bedrooms. A three-colour product can be useful when one room needs more than one lighting mood, provided the fitting and control setup are suitable.
If you want dimming, check that the lamp is listed as dimmable and confirm that the installed dimmer is suitable. Do not assume every LED lamp will work with an older dimmer.
Use this table to narrow the choice. Product pages remain the source of truth for the exact listing details and current availability.
| Decision | Look for | Check before ordering |
|---|---|---|
| Existing GU10 fitting | A GU10 LED lamp in the wattage and colour you want | Socket type, physical clearance and whether the fitting accepts the lamp shape |
| Existing MR16 fitting | An MR16 lamp with the correct supply arrangement | 12V supply, transformer condition and dimmer compatibility |
| Flexible colour choice | A listed 3CCT or colour-selectable downlight | How the colour is selected and whether the setting is changed before installation |
| Dimming required | A product explicitly listed as dimmable | The lamp, dimmer and driver combination as one system |
These examples come from the live LED downlights collection. Open the product page for the current specification, variant details and availability before you buy.
