Latest “AstralTech” optical system developed by SmallRig: Patent light source: larger and higher-power LED chip produces light more efficiently by contrasting output power with output illuminance. All else being equal, its illuminance outperforms comparable peers by more than 35%. High-transmittance front glass: tailor-made beaded glass with six layers of coating has a transmittance of more than 97% in the visible wavelength range, ensuring lossless light flux and even color mixing without flares. Patent COB bead arrangement and heat dissipation technology: unlike ordinary SMD, COB provides even color mixing. Board made of rolled aluminum sheet and composite copper ensures high reflectivity and thermal conductivity. Max illuminance: 115,000Lux (1m) (at 5600K, with reflector). SmallRig RC 350B, SmallRig’s new generation of powerful COB LED video light, employs the “AstralTech” optical system and a 55-degree hyper reflector to realize 115,000Lux (1m). It features CRI 96+ and TLCI 97+ for accurate color rendering and reproduction, outperforming predecessors, a GaN (Gallium Nitride) adapter that allows for power efficiency of at least 95%, as well as a cushioning head support system to protect the light. This item, made of metal and V-0 non-inflammable material, is 20% lighter and can be controlled either by the switch, SmallGoGo App, or control panel (optional). The Bowens mount supports most light-control accessories to create varied lighting effects. Besides, a carrying bag is included for easier storage and transport. The 5 SKUs only have different plug specifications. 3965-US, 3966-EU, 3967-UK, 3968-AU, 3969-JP.
