Problem
The store experienced dimming and color shift in accent lighting, plus occasional breaker trips when seasonal window displays were added. Existing track and driver locations were hard to service. Staff had to reset breakers during peak shopping hours, risking POS downtime. The owner wanted a plan that kept the storefront aesthetic intact while making maintenance and future seasonal load changes straightforward.
Site conditions
- Active retail space on a busy block; work scheduled before opening
- Mixed LED retrofit lamps and old low-voltage drivers tucked above a dropped ceiling
- Shared circuits with POS and signage causing occasional trips
- Limited storage for ladders and materials during open hours
- Ceiling grid included existing sprinkler heads and HVAC diffusers, requiring coordinated clearances
Diagnosis
Testing showed incompatible retrofit lamps with aging drivers and overloaded shared circuits. Voltage fluctuation matched trip events when window heat lamps and signage were on. A dedicated lighting circuit with new drivers and serviceable locations was needed. We also identified miswired neutrals that created slight flicker under dimming, and noted that track runs were daisy-chained in a way that complicated aiming and lamp replacement. A load table comparing seasonal window displays versus normal operation helped the owner decide which fixtures to place on the new dedicated circuit, cutting risk of future trips.
