Frequently Asked Questions - FastBox FB-20K Angler
How do I trigger the FastBox FB-20K flash wirelessly?
The flash supports 2.4GHz wireless triggering. Use a compatible transmitter (sold separately) in the sync port or mount it on the hot shoe adapter. Alternatively, use the built-in optical slave mode.
What is the maximum sync speed for this studio flash?
The maximum sync speed depends on your camera's shutter type. Typically, you can sync up to 1/200s with a focal plane shutter. For high-speed sync, use the HSS mode if available with a compatible trigger.
Can I use the FB-20K with battery packs?
No, the FB-20K is designed for AC power only (110-240V). It does not have battery pack compatibility. For portable use, consider a battery-powered model.
How do I replace the flash tube?
Unplug the flash and wait 10 minutes for capacitors to discharge. Remove the reflector or protection cap. Unscrew the retaining ring, carefully pull out the old tube, and insert a new FB-20K flash tube (spare part). Reassemble in reverse order.
What is the recommended modeling light bulb?
The modeling light uses a 150W halogen bulb (G6.35 base, 120V or 230V depending on region). Replace with the same type to avoid overheating.
Why is my flash not firing?
Check that the power cable is securely connected and the main switch is on. Ensure the flash is fully charged (ready light on). Verify sync cable or trigger is properly connected. Try optical slave mode as a test.
Does the FB-20K have a built-in reflector?
The flash head comes with a standard 50° reflector included. Optional reflectors, softboxes, and umbrellas can be attached via the umbrella holder (side hole).
How do I clean the flash head?
Use a soft, dry cloth to wipe the outer shell. Do not use liquids or abrasive cleaners. Keep the flash tube and reflector free of dust; gently blow off debris with compressed air.
What safety precautions should I take?
Always use the protective cap when not in use. Avoid touching the flash tube during operation (hot). Unplug before maintenance. Do not cover ventilation slots. Use only the specified fuse (8A/250V).
Where can I find spare parts?
Spare parts such as flash tubes, modeling bulbs, sync cords, and reflectors are available from Angler dealers or online retailers. Use the part numbers listed in the user manual.
