Noel and I were looking at video light for HPX and unfortunately, the IDX solution seems would not work on HPX.

Does anyone know a good solution for a video light for HPX?

EDIT: I just found out the connecter on the side of the A/B battery mount can be used with the IDX light.

Yep, and the switch under the AB plate: one side the Powertap (connector thingy) is always on, other side it's only on when rolling. (nice for light)

Ahhh i thought it was actually on and off... thought that the fact it was only on when rolling was just how the light worked... haha Cheers.

Kaku I spoke to Fujiya Avic yesterday, there is an IDX battery mount that has the connector. Bit cheaper than going with the AB which are heavy on price for the good models.
