NOTICE: We are experiencing trouble with inventory and currently do not have an ETA for restocks. We apologize for this inconvenience


Got questions? Here are some common answers.

My strobe is not syncing with my camera, how can I fix it?

Please check to make sure the strobe and trigger are both on the same channel. Next, locate the “TEST” button on your strobe, and press to confirm that your strobe is in working order. Pressing the button should cause a flash.

Firmware could also be an issue. Roughly any camera made after 2019 (Nikon Z6ii, Z7ii, D780, Canon R5, R6, etc) has a high chance of not having its update and unfortunately at this moment, we do not have an ETA for firmware updates. Currently, we are still recovering from the pandemic to get firmware stocked for our customer and it is a top priority for us. The global chip shortage, rise in ocean freight costs, and pandemic have caused major delays and has also caused some disruption to our engineering team. We are working hard and have all hands on deck but as of right now we do not have an ETA for firmware. We apologize again.
