SmallRig RC450D COB LED Video Light (JP) 3974

SmallRig RC450D COB LED Video Light (JP) 3974

1. 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: double-sided, six-layer coated glass has a  transmittance of more than 97% in the visible wavelength range, ensuring lossless light flux.

High reflective COB and heat dissipation technology: board made of rolled aluminum sheet and composite copper ensures high reflectivity and thermal conductivity.

Illuminance rivals 1.2K HMI Fresnel; max illuminance: 172,000Lux (1m) (at 5600K, with reflector)

2. CRI 96+ and TLCI 97+ mean accurate color rendering and reproduction.

3. GaN (Gallium Nitride)  adapter has a power efficiency of at least 95% with lower heat generation and features a locking design and a steel wire cable tether for more safety.

4. The Non-stop damping support system offers safe cushion and smooth tilt adjustment.

5. Quiet cooling fans with intelligent temperature control algorithm improve heat dissipation and produces only 32dB sound within 1 meter, suitable for video recording.

6. Lightweight design:

Made of metal and V-0 non-inflammable material, making the light 20% lighter.

GaN (Gallium Nitride) adapter is 26% smaller and 200g lighter.

Detachable cushioning head helps save storage room for easier transport.

7. Three different ways of control: light switch / SmallGoGo App/ control panel (optional).

8. Bowens mount supports most light-control accessories to create varied lighting effects.

9. Light plus the included carrying bag weighs only 8.5kg for easy storage, transport, and all-around protection.

Product Description


SmallRig RC450D COB LED Video Light (JP) 3974

SmallRig RC450D, SmallRig’s new generation of powerful  COB LED video light,  employs the “ AstralTech” optical system with a 55-degree hyper reflector to realize 172,000Lux (1m) and rivals 1.2K HMI Fresnel when working with a Fresnel at the same beam angle tested at 3m@5600K. 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 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.

Scenarios: Filming, Content Creation, TVC Commercial Photography, Live Streaming, Studio Lighting, Graphic Photography, High-Speed Photography, etc.
