New light fixture holes do not match the old junction box? Learn what to measure and what solutions can help before drilling.

The base plate covers wires, old screw holes and ceiling marks. Measuring it before buying helps make the installation cleaner and easier.

A three-colour light may change each time because of its switching cycle, lack of memory function, fast wall-switch operation, remote-control use or multiple fixtures going out of sync.

A short delay can be normal with LED drivers, memory functions, dimmers or cold conditions. A long, worsening or irregular delay should be checked.

Lampshades can yellow because of heat, UV exposure, dust, grease, smoke or material ageing. Whether they can be restored depends on the material.

Two new lamps can appear different even if they look identical. Colour temperature tolerance, LED batch, diffuser design and room surfaces can all change the perceived light colour.
