What's the difference between spark ii 400w and Jinbei Photography Lamp dpe-400w?

There are many series of Jinbei Flash.

For example, Jinbei M2 series belongs to the lowest-end series of Jinbei, while Jinbei DP series belongs to the higher-end flashing lights. The main difference is the callback speed. The callback interval of DP series is very short, which means that you can shoot at high speed without worrying that the flash can't keep up with the shutter speed.

M2 series will have a relatively large callback interval.

Not suitable for snapshots, now use German Speth flash.

This lamp responds quickly and has good quality.
