When professional lighting manufacturers search for a stage lighting optical components supplier in China, the core challenge they are trying to solve is almost always the same: how to achieve uniform, high-brightness, narrow-beam color mixing without the maintenance headaches and color fringing that plague conventional transmissive systems. Toplite International Co., Ltd., operating under the brand TOPLITE and headquartered in Panyu District, Guangzhou, P.R. China, has built its entire product strategy around solving exactly this pain point for manufacturers of imaging lights, cutting lights, spotlights, wash lights, floodlights, and gobo projectors.
Understanding the Core Problem in LED Color Mixing
Professional lighting manufacturers working with multi-color LED sources frequently encounter uneven color mixing, color fringing caused by transmissive color-mixing methods, overly wide beam angles, and optical systems that are difficult to maintain or upgrade. Film, television, and stage lighting applications in particular demand uniform light output, controllable beam angles, and high brightness packed into compact optical modules. Toplite positions itself as a supplier of optical components and color-mixing systems specifically engineered to address these constraints, built around its patented STONEHENGE optical integral matrix components, MRDB reflective optic barrels, and a matched line of light guides and lenses.
The STONEHENGE Series: Patented Optical Integral Matrix Technology
At the center of Toplite's technical approach is the patented optical integral matrix color-mixing design, marketed under the STONEHENGE name. This design focuses and fully mixes different LED colors into a flat light source, delivering high brightness, high color-mixing uniformity, and a narrow beam angle — directly countering the wide-beam, uneven-mixing issues common in multi-color LED modules.
The STONEHENGE OS Series includes the OS300 and OS600 models. The OS300 combines 6 LEDs (6070 RGBW 4-in-one or 7070 RGBACL 6-in-one packaging) into a 360W module with a beam angle of ≤35° at 50% intensity, while the OS600 scales up to 12 LEDs and 720W with a tighter ≤26.5° beam angle at 50% intensity, suited to more demanding lighting applications.
The STONEHENGE AL Series (400AL, 600AL, 1000AL) uses an aluminum shell and 5050 RGBW 4-in-one LED packaging across configurations ranging from 32 LEDs at 640W up to 88 LEDs at 1,760W, each maintaining a consistent 40° beam angle at 50% intensity and 53° at 10% intensity — demonstrating that Toplite's optical matrix design scales predictably across power tiers.
The STONEHENGE RGBW Series (120RGBW, 240RGBW, 480RGBW) is built for 5060 RGBW 4-in-one packaging, with beam angles tightening as power increases: ≤51° at 120W, ≤43° at 240W, and ≤39° at 480W, giving manufacturers a graduated set of options depending on brightness and beam-angle requirements.

The MRDB Series: Reflective Optic Barrel Technology for COB LEDs
For manufacturers working with colored COB-type LED light sources, Toplite offers the MRDB Series LED Color-mixing Optic Barrel, a high-performance reflective optical barrel designed for film spotlights, photography lighting, long-distance floodlights, zoom wash lights, and projection imaging lights. The differentiated value here lies in its mirror-reflection design, which achieves an internal surface reflection rate of up to 99%, combined with a micron-level double-layer diffuser and a high-precision coated glass lens. This combination is specifically engineered to eliminate the color fringing that is common with transmissive color-mixing methods — a direct answer to one of the industry's most persistent pain points.
The MRDB lineup spans multiple models to match different LED LES sizes and output requirements, from the MRDB35-130A and MRDB35-130B (supporting 8~13mm LED LES) through to the MRDB50-300B (supporting 24~30mm LED LES with a 63mm optical barrel light emitting surface). Beam angles at 50% intensity across the series range from 45° to 54°, while beam angles at 10% intensity range from 80° to 88°, giving lighting engineers precise control depending on the fixture being designed.
Light Guides and Lens Combinations: Customization at Every Scale
Beyond the core matrix and barrel technologies, Toplite supplies an extensive range of light guides made from optical glass with high surface finish and light transmittance, assembled in heat-resistant plastic brackets with a glass diffuser on the head. These are organized by LED power tier — up to 60W, up to 40W, and a bare glass rod category also rated up to 60W — and support LED outer packaging sizes including 2020, 5050, 5060, 6070, 7070, and the OSRAM LZ7-PLUS package. Light emitting surface shapes include square, circle, octagon, and hexagon configurations, giving manufacturers flexibility in how light is shaped and emitted from the final fixture.
For applications requiring wide-range zoom, Toplite's Combination of Light Guide and Lens products — the PST5320 and PPT6219OP — are PMMA lenses designed to pair with the light guide models above. The PST5320(Φ53×20mm, 45.5mm focal length) achieves zoom ranges from 5° to 60°, while the PPT6219OP (Φ62×19mm, 58mm focal length) extends that range from 4° to 60°, including compatibility with OSRAM LZ7-PLUS-based 7243 light guide models.
Toplite also references companion series in its application guidance: the TOP-GF Series Glass Fresnel Lenses, available in diameters from Φ50 to Φ350mm and angles from 2° to 80° for zoom or fixed-focus spotlights, and the IMM Series Lens Assemblies, spanning diameters from Φ44 to Φ140mm for imaging-light applications requiring uniform light spots and sharp imaging.

Service Model Built for Manufacturers, Not End Users
Toplite's business model reflects its positioning as a component supplier rather than a finished-fixture brand. Bulk orders are limited to optical parts, while smaller sample orders can include an assembled STONEHENGE LED matrix module combining the optical part with an LED matrix light source — allowing manufacturers to evaluate performance before committing to large-scale production. Toplite provides drawings and technical support to customers building their own LED matrix light sources, along with customization of installation structures, power ranges, sizes, and beam angles. The company notes that final product performance is subject to actual batch production conditions.
Conclusion
For professional lighting manufacturers in film, television, and stage lighting sectors evaluating an optical components supplier in China, Toplite's combination of patented STONEHENGE matrix technology, high-reflectivity MRDB barrels, and an extensive, customizable light guide and lens catalog addresses the specific technical pain points of uneven color mixing, color fringing, and inflexible optical systems — all backed by direct technical support for custom builds.
