The Master MR15 LED floodlight from Midstream Lighting represents a robust and efficient lighting choice for large-scale applications demanding exceptional light output and long-term reliability. Capable of producing up to 245,000 lumens, this high-output luminaire combines exceptional optical control, durable materials, and integrated electronic systems to deliver consistent performance in even the most demanding environments. Its modular construction enables flexible configuration for various site requirements, while its compact, low-maintenance design ensures dependable functionality throughout extended operational lifespans.
Built with high-grade materials to withstand outdoor conditions, the MR15 incorporates a corrosion-resistant 3Cr12 stainless steel frame with an anti-corrosive primer and powder-coated finish. The heat management system employs anodized extruded aluminum alloy (AL6060) heatsinks to maintain optimal thermal balance, helping preserve luminous efficiency and extend component life. The entire luminaire assembly carries an IP66 protection rating, providing resistance to water ingress from powerful jets, while an IK09 impact rating ensures resilience against physical shocks. The bracket allows multiple fixing options, increasing installation versatility across masts, structures, or facility frames.
The MR15 integrates modern lighting control interfaces such as DALI-2 and DMX, offering seamless compatibility with event or area control systems for dimming, zoning, and synchronized light show capabilities. A single remote driver, also IP66-rated, can be mounted either on the luminaire bracket or at the mast base to simplify installation and service access. Its high electrical efficiency—rated at 95.5%—is complemented by a stable 0.95 power factor and surge protection rated at 10 kV line-to-earth and 6 kV line-to-line. Automatic recovery mechanisms safeguard the unit from short circuits and thermal overloads, while the driver’s adaptive output control maintains consistent light levels under varying conditions.
The optical assembly includes an anti-yellowing PMMA refraction matrix designed to sustain clarity and minimize degradation over time. Available in a range of color temperatures from 3000 K to 5700 K with CRI options of 70, 80, or 90, the MR15 supports diverse application environments—from sports and event venues to industrial or large-area facilities. Specialist optical control minimizes spill light, reduces glare, and enhances uniformity, creating well-defined illumination with minimal disturbance to adjacent areas.
Performance longevity is a key characteristic, with lumen maintenance values rated at L90B10 for 90,700 hours and L70B50 beyond 140,000 hours. Operating reliably between -40°C and +50°C and within humidity levels up to 95%, the MR15 performs consistently across diverse climates. Weighing 27.4 kilograms and measuring 572 x 427 x 188 mm, the luminaire combines substantial optical power with manageable weight for streamlined handling and mounting. Manufactured in Europe, the MR15 supports short lead times and reliable regional quality standards—an asset for projects requiring both speed and dependability.
