The light may be dead, intermittent, hot, visibly damaged or tripping protection. Sometimes the fault is local to the fitting or lamp; sometimes it points to loose connections, driver failure or a wider issue. Do not keep using anything that smells hot, shows scorching or keeps tripping.

What can change the scope

  • Burn marks, heat, smell or repeated trips need prompt checking.
  • A like-for-like replacement is only suitable if the existing point is safe.
