This is the head of a Photona strobe. It can be fired at full power with a 2400W generator. It has been in storage for about 3 years due to reduced usage. The flash tube has been replaced with a new one, but there is a slight blackening at the base. Before listing, I tested its operation by firing it at the minimum power of 37W and the maximum power of 2400W. The modeling light also turned on. If you have any questions before purchasing, please ask in the comments, and I will provide additional images, etc. It is an old item, so please understand that no returns or refunds are accepted after purchase.
