At MHSC Energy, every lighting layout is designed not just for today’s conditions, but for the operational reality of tomorrow. Our recent project at McCoy’s Building Supply in Brownwood, TX is a perfect example of how we combine smart design, adaptable layout strategies, and real-world performance considerations to help contractors and facilities teams stay ahead of the curve.
Purpose-Driven Design
The Brownwood facility includes warehouse-style racking, which introduces some common—but manageable—lighting challenges. Racks can block vertical light and create shadow zones if fixtures are placed directly overhead. Our goal is to design around those constraints, keeping the lighting consistent and functional, even in complex warehouse configurations.
We used our signature approach: three rows of 8–9 fixtures each, spaced for maximum photometric coverage without waste or overlap. In areas with denser racking, we make every effort to avoid placing luminaires directly above the shelves. But the fixtures themselves—LHB11550s—come with long cords and flexible mounting options, giving the client and install teams the ability to adjust positions later if the racking shifts.
Luminaire Details
This project features the LHB11550, a reliable, high-output luminaire known for its performance in warehouse and retail environments. We selected this model specifically for its tight beam control, lumen stability, and maneuverability in racked layouts.
Fixture Specifications:
Model: LHB11550
Lamps per Fixture: 1
Lumens per Fixture: 16,858
Total Fixture Quantity: 154
Total System Lumens: 2,595,532
Total System Wattage: 17,309.6 W
Light Loss Factor (LLF): 0.950
Average Illuminance: 91.50 lux
This lux level is right in the target range for warehouse spaces with shelving, where the visual environment needs to be bright enough for safety and accuracy, but not so intense that it causes glare or eye strain.
Layout Dimensions & Environmental Conditions
Our layouts use precise feet/inches coordinates, designed to make installation faster and more accurate. As always, we build around standard values for warehouse ceiling heights and light plane calculations.
Layout Parameters:
Wall Height: 20 ft
Mounting Height: 18 ft
Workplane Height: 2.5 ft
Reflectance Settings:
Ceiling: 0.80
Walls: 0.50
Floor: 0.20
These reflectance values are typical defaults and help us model conservatively. We prefer to design to the low end of brightness expectations—ensuring we’re not overstating light levels on paper. In real-world conditions, facilities often end up brighter than predicted, especially with lighter finishes on walls and floors. It’s a “better-safe-than-overpromised” approach that’s earned us long-term trust with contractors and facility managers alike.
Adaptability for Long-Term Performance
In this layout, flexibility was a key requirement. Since the space includes active racking, we intentionally avoided hard-mounting fixtures over shelving where possible. The long cords on the LHB11550s allow for easy repositioning post-install—so if the racking shifts, the lighting can shift with it.
This adaptable approach means the space won’t just look good on day one—it will continue to perform well even as storage and usage patterns change.
Let’s Work Together
At MHSC Energy, we specialize in layouts that do more than meet spec—they solve real installation challenges, simplify quoting, and build confidence into every project. If you’re a lighting contractor or project manager looking to streamline your next job, we’re ready to help.
