The design of the 7’UP lamp necessitates routing the wires from the driver to the LED’s through holes in the bulkhead and the LED PCB. By using the bulkhead as a template the holes were marked with a felt tip pen. I did a Delrin fixture to hold the LED PCB in place while drilling. This also protected the LED domes, which are made from silicone and are quite fragile.
