Question 1

How accurate are the savings estimates?

Accepted Answer

The estimates are directionally accurate and intentionally conservative. They are based on the wattage values you enter and your operating schedule. Real-world savings can be higher or lower depending on your actual utility rate, fixture condition, controls such as dimming or occupancy sensors, and demand charges.

Question 2

Can commercial buildings qualify for utility rebates?

Accepted Answer

Yes. Most commercial buildings in New York, New Jersey, Connecticut, and Pennsylvania can qualify for utility rebate programs when upgrading to LED lighting. Rebate amounts depend on your utility provider, fixture count, and program availability. Programs from Con Edison, PSE&G, JCP&L, PSEG Long Island, Eversource, United Illuminating, and others can cover a significant portion of the project cost. VK Light Solutions handles all rebate paperwork on your behalf.

Question 3

Do warehouses save more with LED upgrades than other building types?

Accepted Answer

Warehouses and distribution centers typically see the highest returns from LED lighting upgrades. Large fixture counts, long daily operating hours, and high wattage metal halide or HPS high-bays create substantial energy waste. A 200,000 sq ft warehouse with 400 fixtures running 12 hours per day can save $60,000 to $100,000 annually after an LED upgrade — often with payback periods under 18 months when rebates are included.

Question 4

Can office lighting upgrades reduce electricity costs?

Accepted Answer

Yes. Offices with older fluorescent troffer fixtures — particularly T8 or T12 systems — see 55 to 68 percent energy reductions when upgraded to LED flat panels. Adding occupancy sensors in conference rooms, corridors, and restrooms typically reduces LED runtime by an additional 40 to 50 percent, compounding the savings further. Many office retrofits pay back in 2 to 4 years even without utility rebates.

Question 5

How long do LED fixtures last compared to older technology?

Accepted Answer

Commercial-grade LED fixtures are rated for 50,000 to 100,000 hours of operation, compared to 10,000 to 20,000 hours for metal halide and 20,000 to 30,000 hours for fluorescent lamps. In a warehouse running 12 hours per day, a 50,000-hour rated LED fixture would last over 11 years before needing replacement — versus 2 to 3 years for metal halide. This significantly reduces maintenance labor and lamp replacement costs beyond the direct energy savings.

Question 6

What electricity rate does the calculator default to?

Accepted Answer

The calculator defaults to $0.18 per kWh for New Jersey and $0.20 per kWh for New York — approximate commercial averages. Your actual rate may differ depending on your utility provider, time-of-use pricing, and demand charges. You can enter your exact rate in the Electricity Rate field for a more accurate estimate.

Question 7

What is a typical payback period for a commercial LED retrofit?

Accepted Answer

Most commercial LED retrofit projects in New York, New Jersey, Connecticut, and Pennsylvania pay back in 1 to 3 years when utility rebates are included. Without rebates, payback typically ranges from 2 to 5 years. In high-usage facilities like warehouses running 12 to 16 hours per day, payback is often under 18 months even before rebates are factored in. The exact payback depends on fixture count, operating hours, and your current electricity rate.

Question 8

How does the CO₂ reduction estimate work?

Accepted Answer

The approximate CO₂ reduction is calculated using the US EPA national average emission factor of approximately 0.386 kg CO₂ per kWh. This is a commonly used benchmark for estimating the environmental impact of electricity reductions. The actual CO₂ reduction varies by region and utility fuel mix. The Northeast grid generally has lower emissions than the national average.
