Portable Flash and Studio Strobe Trigger Voltages
Friday, 05 February 2010
Feb 8th 2010:
We're currently updating this data to include more popular (and common) data on newer model flashes, strobes and triggering devices. We're also creating a new group on flickr for folks to post their findings on particular lighting gear.
We are currently adding to and updating (Feb 2011) Trigger Voltage Metrics in the tables below. We encourage your participation in this endeavor by submitting your results to our growing list. It's pretty easy to check your trigger voltage, for more information and instructions on how you can participate, visit our Flickr Group by following this link
