Replacing a 400W Metal Halide bulb is one of the most effective ways to reduce energy costs. Modern LED replacements use only 160W to produce the same massive light output (around 30,000 lumens), while eliminating the long warm-up times.
Estimated annual savings: $34.16/year (3 hrs/day at $0.13/kWh)
Energy Savings Calculation
*Default calculator uses 3 hrs/day. **Industrial/commercial 400W fixtures often run 12+ hrs/day, yielding massive savings of $150+ annually per fixture.
