Philips XWC120 and XWC121

Two SOX bulkheads I've been looking for for years were the Philips XWC120 and 121. The wedge design of them makes them a really versatile clean design, spreading light exactly where its needed.
Originally acquired as PL examples, I swapped the 120 tray for a SOX ready tray, and the 121 was converted to SOX by carefully copying the wiring from photo's online. The igniter had to be a SX72 since a SX26 is near impossible to find. With the other bulkheads I have, I'm out of spare 18w lamps, so these will be very seldom used as a result sadly, unless spare lamps come up.
