Unsure of which MR16 you need? This article will answer any questions you might have about these compact spotlights.

The Multifaceted Reflector (MR) is of the most widely used spotlights used in both commercial and residential applications. The reflector inside the MR controls the beam angle of the lamp and is available in different beam angles.

MR light bulbs are extremely popular because the amount of light they offer compared to the amount of energy consumed. Halogen light bulbs consume less electricity than incandescents, but they still use more energy than LED lamps. Many utility companies are encouraging their subscribers to switch to LED light bulbs to reduce energy consumption. In return, consumers see a reduction in their energy bills and less heat put off from these bulbs.

There are two base types for MR16 light bulbs, the GU10 (twist), and the two pin GU5.3 (push to fit). The GU5.3 base commonly operates using 12 volts while the GU10 operates off 120 volts. Voltages vary greatly across all bulbs types so always check the specifications and ensure your fixture is compatible with both the fitting and voltage.

When replacing your low voltage Halogen MR16 with an LED you might have to change your transformer. Most power supplies require a minimum of a 20 Watt load. Viribright’s MR16s use only 3.2 Watts of energy and the current transformer may not be able to run this low of a wattage. The current transformer should list the maximum and minimum load capabilities. For your safety, we recommend using an electrician to change out any electrical units.

Viribright offers MR16 and GU10 bases in all three major color types including Warm White (2700K), Cool White (4000K), and Daylight 6500K. We have the right color or base type to fit your needs.

Seven Springs Apartments

Project Description

Seven Springs is a 33-acre campus located in College Park, Maryland. The project is owned by The Ross Companies, a family-owned real estate development and property management firm based in Bethesda, Maryland. The property has been in their portfolio since 2002. Ross specializes in the multifamily and mixed use communities throughout the Washington, DC Metro Area and currently manages just over 11,000 multifamily units.

Seven Springs is a project very dear to the hearts of its owners. At the time of acquisition, it was one of their largest single assets and it was wholly owned by the family, so when it came time to selecting a partner for this energy savings contract, they were very cautious when it came to selecting a partner. They wanted a company that was able to understand not just the value of the savings but the underlying value of the real estate asset and was able to tailor a proposal accordingly. They selected NextGen LED.

NextGen LED is an ROI-driven energy savings company that focuses on pairing the best performing products, with strong warranties, and the most aggressive pricing to customize aggressive op-ex cost reduction initiatives for their clients. NextGen LED partners nationally with public and private companies in the commercial real estate markets to implement portfolio-wide energy savings contracts.

NextGen was co-founded by a former real estate executive that specialized in savings-based energy efficiency projects, and a structured finance entrepreneur who has put together over $500 million in green-tech capital markets transactions.

Seven Springs contains multiple property types in a single location. One high rise apartment building with ground level retail and daycare facility, two mid-rise buildings, 20 garden apartments, and a clubhouse/leasing center with two outdoor tennis courts and a pool. In total there are 982 units and 16,864 light bulbs. Viribright provided all of the interior unit and common area lighting for the facility. A total of over 13,000 lamps.

We were very pleased to provide the Viribright LED bulbs for this exciting project through our partners NextGen. Working with NextGen and their professional team on this and other projects has been very positive.

LED Performance Summary

PERFORMANCE INDICATOR Existing Lighting Program Led Retrofit Program Savings
Total Lamp Count 16,864 14,245
Annual kWh SAVED 2,169,301 646,865 70%
Annual Electricity REDUCTION $260,316 $77,624 $182,692

The project had a 2.37 year payback and an ROI of 39.20%. Total 10 year savings for this contract is $2,171,010. The additional savings comes from a 5-year average on annual lamp and ballast costs that were supplied to NextGen directly from the client.

Project Finance:

The total project cost was $778,339. NextGen LED provided in-house financing for 80% of the project costs at 4.2%. NextGen was able to secure Small Business utility-based financing at 0% for the remaining 20% of the project costs, bringing the total cost of capital to 3.36%. NextGen LED (through a total of 29 individual rebate applications comprised of small business and existing buildings) was able to secure $263,749 in rebate dollars for this project. NextGen provided financing for 100% of the project costs and the client took the rebate dollars as cash upfront to implement other property-wide upgrades. Ross Management put no money down, received a check in the amount of $263,749 and was immediately 15% cash positive on lighting related electricity. After the 5-year finance term, the client total savings jumps up to 70% for the remainder of the project life.

Because this was an energy-savings contract, retrofits were recommended over new fixtures. The project deliverable that the client was trying to achieve was financial savings. However, the clearer, crisper light of the LED provided a significant aesthetic enhancement to the property. Hallways were brighter, colors were bolder and the consistency of color across all hallways created an upgraded feel to the facility that was unexpected by ownership and an added, uncalculated benefit in terms of resident satisfaction.
