How Emergent Cold cut lighting energy 62% across 480,000 sq ft with Spark.
A 24/7 cold-storage operator replaced 1,400 fixtures, then asked Spark to do the rest…
Industries
Lighting that performs in the conditions other systems can't.
Reliable smart lighting for cold storage and refrigerated environments — cutting energy use, reducing maintenance, and standing up to the temperatures your operation runs at every day.
60–80%
of cold-storage lighting energy is wasted on empty aisles and idle zones.
The problem
In cold storage, every fixture you replace is a fixture you have to access — in the cold.
Cold storage operations run continuously, at temperatures that punish equipment, with maintenance windows that are short and expensive. Legacy lighting in these environments fails earlier, draws more power, and adds heat that the refrigeration system has to remove. The result is a hidden compounding cost — paid in energy, paid in maintenance, paid in HVAC load.
The right lighting is engineered for the conditions, not retrofitted into them.
The solution
Lighting designed for the cold, monitored from anywhere.
OPTIMA specifies fixtures and sensors rated for low-temperature performance, sealed to the moisture and condensation conditions specific to refrigerated environments. The system activates only where there is activity — picking, replenishment, dock-in, dock-out — and dims when zones are idle. Spark provides continuous visibility into lighting performance and energy consumption, even in zones your team rarely enters.
What we deliver
Fixtures rated for ambient temperatures down to −30°C, sealed for refrigerated conditions.
Reduced HVAC load — LED systems generate substantially less heat than legacy alternatives.
Activity-based controls calibrated to cold-storage workflows.
Remote monitoring and predictive alerts through the Spark platform.
Impact
Typical energy savings: 60% to 80% reduction in lighting energy.
Lower lighting energy consumption, verified continuously.
Reduced HVAC and refrigeration load.
Longer fixture life under cold-chain operating conditions.
Fewer maintenance interventions in low-temperature zones.
Cold-chain operators who run on Spark.
The cold is hard on equipment. We design for that.
