The Godox AD600Pro Witstro 

Color Temperature Improvements

One major and welcome improvement is a stable color temperature mode, which locks the strobe within 75 degrees of 5600K over the entire power range. Early findings slot this ahead of even Broncolor and Profoto. This is certainly promising and could potentially negate a major advantage those two brands had over the previous Godox model. As a previous user of the B1s and now the AD600, I can say you do notice these slight shifts with the latter when culling through a shoot.

Improved Modeling Lamp

Another highlight for me is the improved 38-watt LED bulb modeling lamp versus the ten-watt on the original non-pro model. With this modeling lamp boost, the Pro model is much more versatile as well competitive to the high-priced alternatives. It also becomes useful outside of just dimly lit studios.
