Mosman, Cremorne, and Neutral Bay harbour-side properties combine high property values with the typical Lower North Shore electrical patterns: large multi-circuit boards, extensive outdoor entertaining circuits, pool/spa/jacuzzi equipment, and the salt-air corrosion from harbour exposure.

⚠ Stop — Call Immediately if You Notice Any of These:
  • A burning, plastic, or fishy smell from any downlight
  • Soot, char, or browning around a downlight rim
  • A downlight rim that is hot to touch
  • A ceiling area around a downlight that is warm or discoloured
  • Crackling or buzzing from any fitting
  • Flickering before the failure
  • A downlight that produced smoke when it died
  • Visible insulation on top of fittings (check from the roof space if accessible)

About Why Do My Downlights Keep Blowing?

Heat buildup in ceiling cavities, incompatible LED retrofits in halogen fittings, and failing drivers are the real causes of repeated downlight failure — not the bulbs. Overheating above insulation-covered fittings is a fire risk; call 0433 462 902 or book a diagnostic with Sydney Electrical Service.

Modern LED downlights are rated for 25,000 to 50,000 hours — a globe dying in six months means the fault is upstream of the bulb itself. In Sydney, this clusters in older homes where insulation was later added on top of fittings not rated for contact. Sydney Electrical Service is dispatched 24/7 across every metropolitan suburb.

What to Do Right Now in Cremorne

  1. Note the pattern. Which downlights blow, how often, and how long they last.
  2. Check whether the bulbs are matched to the fitting type and the dimmer (if any).
  3. Switch off the dimmer for the affected circuit and use lamps at full brightness.
  4. Check the ceiling cavity if accessible — confirm whether insulation is in contact with the fittings.
  5. Note any smells, browning, or discolouration around fittings.
  6. Replace failed lamps with the same-spec replacement — note brand, voltage, wattage, and dimmer compatibility.
  7. For repeat failures of the same fitting, the driver or wiring is at fault — book a diagnostic.
  8. Photograph any damaged or discoloured fittings for our dispatch.

Electrical work in Cremorne

Three-phase consumer mains in older established North Shore homes (1960s onwards) are reaching end-of-life simultaneously across the suburb — we see consistent "mains insulation cracked, replacement quote" enquiries from Killara, Lindfield, and Wahroonga.

Common Questions

My downlights last only a few months — is the brand bad?
Possibly — but if multiple brands have failed, the fault is in the fitting, the driver, or the installation, not the lamp. We recommend a downlight audit before throwing more bulbs at it.
Can insulation really kill downlights?
Yes — directly. Insulation laid on top of a non-IC-rated fitting traps heat, the lamp runs at well above its rated temperature, and the driver fails within months. AS/NZS 3000 specifies clearances and IC-rated fittings for use under insulation.
Why does the same fitting blow but the others don't?
A fault specific to that fitting — most often a failing driver, a localised heat issue (closer to a roof timber, in a poorly ventilated zone), or a damaged cable behind the ceiling. Diagnostic test isolates the cause.
Are LED downlights better than halogen?
For energy use and longevity, yes. For installation reliability, only when correctly retrofitted. A halogen-fitting retrofit with the wrong driver delivers worse reliability than the original halogen install.
