Ask a professional to explain the problem of flash and flasher.

Standard flash lamps, whether indoor headlights or ceiling lamps, can be connected to the camera through the synchronous pc port, but some cameras are easy to be damaged when using the PC port, so indoor large photography lamps are equipped with flash lamps.

Most flashers are wireless flashers. The flash of most indoor lamps consists of two parts: a receiver, a pc input connected to the lamp, a transmitter and a hot shoe connected to the camera. Some cameras don't have a hot start, but they can still be connected to the transmitter through a pc cable. A simple flasher includes two channels, which can control two lights, and a more complicated flasher can control multiple lights.

High-end set-top box lamps generally have built-in receivers, so wireless flashing can be realized as long as they are equipped with an original transmitter (some cameras in N have built-in wireless transmitting modules) or multi-lamp wireless flashing.

U2' s products are ready-made, so you don't need to buy any accessories. If practicality is considered, it is recommended to buy accessories.

1, lamp holder, special connector for fixing u2 on the lamp holder.

2. Lamp holder

3, special soft box

4. Reflective umbrella

5, wireless flasher

Thus, wireless flashover can be realized.

At present, I have passed the wireless flash test of 30D D50 D70 and can flash normally.
