I am in the process of making a comprehensive you tube video of recycle times of VLX, VML and ION battery power systems. The video should be finished by next week.
These are extremely accurate tests, using the video SMPTE time codes to accurately measure time from flash to recycle indicators.
Here is a summary of results. I will draw no conclusions here, leaving that to readers.
Also note, VLX™ is now available in Cool Grey as well as the original Purple Haze/Navajo Turquoise versions. See http://www.paulcbuff.com/vlx.php
