Learn how to set up, power, and care for your Godox KNOWLED AT200Bi inflatable LED tube. Step-by-step tips for safe inflation, deflation, and storage.

Quick answer

Inflate the AT200Bi fully before powering it, use the correct voltage, and deflate it completely for storage to keep the tube soft and diffused. Follow the steps below for a safe, repeatable process.

Why full inflation matters for light quality and safety

A partially inflated tube creates uneven diffusion and can stress the internal seams. Always inflate until the fabric is taut but not stretched; the tube should feel firm yet give slightly under pressure. This ensures the soft, uniform light the AT200Bi is designed to produce.

Avoid overinflating: stop pumping as soon as the surface loses visible wrinkles. Overinflation increases the risk of seam damage and reduces the tube's ability to absorb minor impacts.

Powering the AT200Bi: voltage and cable checks

The AT200Bi is a bi-color tube with a wide color temperature range, but it requires a stable power source. Before connecting, verify that your outlet or battery setup matches the specified voltage. Using an underpowered source can cause flicker or prevent the light from reaching full output.

Inspect the power cable and connector for damage each time you set up. A loose or frayed cable is a common cause of intermittent operation and can be a safety hazard.

Step-by-step setup and care

Inflate fully on a clean, flat surface: Place the deflated tube on a clean, flat surface free of sharp objects. Use the supplied pump or a compatible inflator to inflate until the fabric is taut and wrinkle-free. Do not overinflate; stop when the tube feels firm but still slightly yielding. Check for any twisting or pinching at the seams as it inflates.
Verify power compatibility before connecting: Confirm that your power source matches the AT200Bi's voltage requirements. Use only the original power adapter or a verified equivalent. Inspect the cable and connector for damage, and plug into a grounded outlet. Never use a damaged cable or an ungrounded outlet.
Position and adjust for even lighting: Hang or mount the inflated tube using the designated attachment points. Adjust the color temperature and brightness to suit your scene. Keep the tube away from heat sources and sharp edges. Ensure the mounting point can support the tube's weight and that cables are secured to prevent tripping.
Deflate completely after use: Power off and disconnect the tube. Open the deflation valve and gently press or roll the tube to expel all air. Do not fold or crease the tube while it is still inflated. Once deflated, close the valve to keep dust out. Store only when fully deflated to avoid trapped air and seam stress.
Store in a dry, protected place: Lay the deflated tube flat or roll it loosely without sharp folds. Store in a cool, dry place away from direct sunlight and heat. Avoid placing heavy objects on top of the tube. Inspect the tube for wear or damage before each use.
