The #1 profit-killer for commercial lighting contractors isn't labor or lift rentals—it’s December service callbacks.
When a retail-grade LED string fails mid-season on a 30-foot commercial roofline, the return truck roll eats your net margin on the entire job.
Here is why commercial crews standardize on Wintergreen Corporation SMD LED OptiCore™ bulbs and SPT-2 bulk spools:
1. Polycarbonate Shatterproof Lenses: Virtually indestructible under heavy ice loads and accidental drops.
2. Direct SMD Diodes: If an individual diode takes impact, the rest of the string stays 100% lit—zero cascading outages.
3. Heavy-Gauge 18/20 AWG Wire: Engineered for extended commercial runs without voltage drops or dimming ends.
Stop burning fuel fixing cheap bulbs this winter.
