Twin 8w bulkhead.

To the unassuming eye this is just a regular fluorescent bulkhead, however once opened and the gear tray pulled out you can see why its not. Its with huge thanks to Danny for allowing me the opportunity to finally wire in these two JSB starterless ballasts into a bulkhead where they actually fit nicely. There's ample room for a third ballast, but the likelihood of another turning up is very small, owing to the seemingly overall rarity of the ballasts.

The screws that secure the gear tray to the base and the cover screws were missing. Whilst the cover screws were simple to replace, the four for the gear tray required a small insert in the base, also missing. To get round this I simply heated some hex nuts up with the blowtorch and melted them into the plastic. They're surprisingly solid, which is good cause I can now install the bulkhead no issues.

Pictured after a good clean, the bulkhead looks exactly like a generic run of the mill type, its major difference only being evident on start-up. I also like the opal prismatic cover, I only have one other multi tube bulkhead with a similar style cover, and that one is a triple 6w bulkhead.
