Imagina US is a pioneer production company in the U.S. Hispanic TV industry that has a newly built headquarters in Miami, Florida. Owners were seeking low-wattage outdoor lighting for the facility’s parking lots. At first, the owners were looking at 400-watt metal halide fixtures, however, they wanted to consider lower wattage and better quality LED lighting fixtures.

The company turned to Jose Rieumont, executive vice president of Solar Energy Technologies, Inc. in Hialeah, Florida, to identify and install energy-efficient LED lighting products. Rieumot and his team picked MaxLite’s 270-watt Merak® Series LED Roadway Street Lights for the installation, and turned to MaxLite’s lighting application engineering and design team to create a lighting plan with the LED roadway street lights.

The team designed two layouts for the facility to choose from for the 85,000-square-foot lot with 200 parking spots. The metal halide layout included 28 400-watt metal halide fixtures, mounted with single fixtures on the exterior lanes and double-mounted fixtures on the interior lanes of the parking lot. The metal halide layout would have produced an average footcandle reading of 6.3, maxing out at 12.3 and dropping down to just 1.1.

The LED layout included 16 270-watt Merak fixtures, installed in pairs on a 25-foot double-post pole. The facility chose the LED fixture design that enabled an average reading of just over four footcandles, with a maximum reading at 15.9 beneath the poles and minimum of 1.4 footcandles in other areas. The LED fixtures produce 24,300 lumens and offer a long lifetime of 104,000 L70-rated hours, which amounts to more than 23 years of operation when running 12 hours per day. Compared to the proposed 400-watt metal halide fixtures that consume 462 watts with ballast, the LED fixtures will save the production company 896,064 kWh and $130,855 in energy and maintenance throughout the lifetime of the fixtures, based on a $.14 kWh electricity rate.

Reducing energy by up to 70 percent, the Merak fixture is offered in 30- to 300-watt models in Types I, II and III Illuminating Engineering Society (IES) distributions that replace up to 70- to 1,000-watt high pressure sodium or metal halide fixtures, while delivering up to 26,400 lumens. DesignLights Consortium® (DLC)-qualified models include 120-, 180-, 210, 240-, 270- and 300-watt styles in Type III IES distributions in 5000K correlated color temperatures (CCTs).

These LED fixtures can match the photometric overlay of standard high pressure sodium cobra head fixtures, while operating at a lower wattage, and meet or exceed the lumens produced by the incumbent technology. The fixtures are compatible with the latest controls and sensors for optimal efficiency and additional energy savings, and are National Electrical Manufacturers Association (NEMA) photocell-ready.

A durable, die cast aluminum housing and high-impact and sealed polycarbonate lens protects the fixture from wildlife intrusion and natural elements. For optimal thermal management and ease of replacement, each LED module contains an independent heat sink. Stainless steel latches enable tool-less maintenance. Precise aiming is achieved with a mast installation toggle and arm sleeve pivots.
