I recently purchased 8 Focus Beam LED fixtures, and now have 6 not working! one issue is that despite the base of the fixture powering up, the actual head is completely unresponsive. On accessing the menus in the base, it looks like either some of the boards have lost their firmware, or there is no communication with them. Does anyone know where I can find the latest firmware for these, as it does not appear to be on the website (despite ADJ saying that there is a USB port for simple firmware updates, not simple if you don't publish it anywhere!) The other issue with some of them (the ones that still actually do anything!), is that they freeze whilst running a program (DMX), and will start moving again when you give them a little nudge (no use when they're rigged overhead in a nightclub, and the floor is packed!)
Starting to consider sending the whole lot back and getting a refund to buy from a different manufacturer.
