4. Setup Instructions
The RALENO light boxes are designed for quick and easy assembly using high-quality Velcro edges.
4.1. Assembly
- Unfold the light box from its collapsed state.
- Align the Velcro edges of the side panels and firmly press them together to form the cube shape. Ensure all edges are securely fastened.
- Place the light box on a stable, flat surface to prevent tipping during use.
- Connect the DC power adapter to the designated port on the light box and then plug it into a power outlet.
4.2. Backdrop Installation
- Select one of the 6 color PVC backdrops (Black/White/Orange/Blue/Red/Green) based on your product and desired effect.
- Carefully insert the backdrop into the light box, ensuring it lies flat and smooth against the back and bottom surfaces. Avoid creasing or damaging the backdrop.
4.3. Diffuser Placement
Use the provided soft diffusers to soften the light and reduce harsh shadows, enhancing the quality of your photographs. Place the diffuser inside the light box, typically below the LED light strips, to evenly disperse the light.
