The LED COB light SmallRig 3976 RC 450B with AstralTech system (EU) uses a 55-degree hyperreflector to realize 115,000 Lux (1 m). It features CRI 96+ and TLCI 97+ for accurate rendering and color reproduction, surpassing predecessors. Larger, higher-power LED chip produces light more efficiently by contrasting power output with illumination output. Custom-made pearl glass with six coating layers has a transmittance of more than 97% in the visible wavelength range, ensuring lossless luminous flux and uniform color mixing without glare. The laminated aluminum-copper composite sheet panel ensures high reflectivity and thermal conductivity. The GaN (gallium nitride) adapter has at least 95 percent energy efficiency with less heat generation, features a locking design and a steel connection cable for added safety. Quiet cooling fans with intelligent temperature control algorithm improve heat dissipation and produce only 28 dB of sound within 1 meter, suitable for video recording. The 3976 RC 450B with AstralTech optical system has three different control modes: light switch, SmallGoGo app and control panel (optional). The Bowens mount supports most light control accessories to create various lighting effects.
