Introducing Glowstick and Glowball Signature Clusters Oct 22, 2025 Signature Clusters Elevating architectural spaces through signature multidrop arrangements of Glowstick™ and Glowball™ pendants. Precision-engineered and ready to specify. Glowstick Signature Cluster Glowball Signature Cluster Signature Clusters: Tailored, Sculptural Lighting Made Simple For years, OCL has been crafting multidrop lighting installations that bring rhythm, depth, and sculptural beauty to architectural spaces. Now, we’re making that process easier than ever to visualize, specify, and bring to life our signature clusters. Signature Clusters showcase an OCL capability we’ve perfected over many years — the art of transforming pendants like Glowball and Glowstick into refined, dimensional lighting compositions. These guides provide a clear framework for designing clusters that balance design freedom with practical simplicity, helping designers start the conversation with clarity and confidence. Signature Clusters bring rhythm, depth, and sculptural beauty to architectural spaces What Are Signature Clusters? Signature Clusters are ready-to-spec design frameworks that walk designers through the creation of multidrop lighting compositions. To make this simpler, we’ve created a Design & Specification Guide that includes canopy shape options, drop pattern inspiration, and specification details for both Glowball and Glowstick. They’re designed to take the guesswork out of early-stage design, giving designers a starting point that’s flexible enough for creativity, yet grounded in real-world practicality. Why Choose a Cluster? Clusters are the modern evolution of the traditional chandelier — a contemporary way to create visual impact through scale, repetition, and rhythm. Whether you’re designing for an expansive atrium, a lobby statement, or a stairwell feature, clusters provide a tailored solution that feels sculptural, balanced, and bespoke. Choose a cluster when: You want a lighting composition that feels architectural and artful. You’re designing for height, scale, or volume in a large feature space. You want a cohesive, multi-pendant installation with a unified canopy. You need the visual drama of a bespoke piece with the simplicity of a defined system. You value refined dimming performance and a streamlined driver strategy. The result? A lighting centerpiece that’s as efficient as it is expressive. Crafted with Intent Signature Clusters embody OCL’s approach to lighting — purposeful, precise, and beautifully engineered. Each canopy is fabricated from high-grade aluminum, with installer-friendly details that make maintenance simple and serviceable. Designed and built in St. Louis, Missouri, these clusters combine skilled craftsmanship with scalable design flexibility, giving every project both the polish and reliability you’ve come to expect from OCL. Designed for Real-World Simplicity Behind every Signature Cluster is a constant-voltage driver strategy that powers multiple pendants from a single driver. This approach reduces components, installation complexity, and cost — while maintaining smooth, reliable dimming down to 10 %. The tradeoff is intentional: a simpler, more efficient configuration that ensures consistent performance and a cohesive visual appearance across every drop. It’s lighting that feels balanced and intentional at any brightness level, supporting both the visual and emotional tone of the space. Read more about why we use 10% dimming in our guides. From Concept to Configuration: how to create your cluster Each guide walks designers through the process of shaping their ideal cluster, from the first spark of inspiration to a ready-to-quote specification. Decide your number of drops. Determine the density and overall presence you want for your space. As a rule of thumb, two to six drops per square foot of canopy creates the right visual balance. Choose your canopy shape. Square, rectangular, circular, or elliptical — each shape creates a distinct geometry and rhythm. Calculate your canopy size. Determine your canopy size. If you need an assist, our guide includes pre-calculated layouts based on canopy area, helping you choose proportions that align with your design intent. Pick your drop pattern. Level, stepped, wave, swoop, or random — the drop pattern defines the motion and energy of the composition. Or create your own bespoke pattern – with us or in the field. (Choose LVL to field adjust your pattern). Specify your details. Select finish, color temperature, hanging system, and overall height. The dedicated submittal worksheet captures every detail for a clean handoff to quoting. Whether you’re using the guide to configure a single panel or a large multi-section canopy, the process is straightforward, clear, and creative.

Glowstick Signature Cluster Transforming architectural spaces with the refined glow and modern edge of Glowstick luminaires – slender, sculptural, and designed for effortless composition or bold, custom expression. Glowstick™ Signature Cluster Glowball Signature Cluster Bringing architectural lighting sculptures to life with spherical elegance using Glowball luminaires as artful, dimensional compositions – preconfigured for simplicity or fully configurable for impact. Glowball™ Signature Cluster A Few Project We’ve Done Every space tells a story — and light is the language. These projects show how Glowstick™ and Glowball™ Signature Clusters transform ideas into installations, turning open volumes and vertical voids into sculptural experiences of light. Eldrige Oaks In the heart of Houston’s energy corridor, Eldridge Oaks by IA Interior Architects showcases a blend of luxurious amenities and biophilic design, capturing the essence of nature while elevating the workplace experience. This 81-drop Glowball Cluster uses RGBW and each drop is individually addressable by utilizing a proprietary custom made decoder OCL had designed specifically for this project. We affectionately call it Candy Rain. Toyota Financial Services Atlanta Ware Malcomb designed and specified a Glowball™ Signature Cluster that cascades through the central stair, connecting floors with soft, sculptural light. Its balanced composition complements the biophilic textures and natural materials, enhancing the workspace’s sense of openness and connection. Sauk Trails Plaza II Wide open floor plans with an abundance of natural light were key to the design aesthetic. Every office has access to natural light. The 3-story monumental staircase is the centerpiece, creating a 50 foot natural light well that houses an 72 drop, DMX-controlled Glowstick Signature Cluster. The fixtures are programed to swell and flow, handing light off from one piece to another. The light can cascade, change speed and move horizontally and vertically throughout the fixture. The patterns and effects available are limitless. 1001 Pennsylvania Avenue NW A Glowstick™ Signature Cluster defines the new glass-enclosed lobby with vertical rhythm and sculptural precision. Its suspended lines of light mirror the bronze-clad reception and natural stone palette, creating a grand, modern welcome. A stunning project in the nation’s Capital by Ware Malcomb. Need Help?
