Various fluorescent bulkheads After spending a day and age wiring these, i finally was able to put power to them. A few blinks and they all lit up as expected. From left to right we have 4 Coughtrie SFB16's, followed by their larger brother, the SFB32. Next up we have a Philips MFB16, which is now technically a MFB24 since it was converted from 2 tubes to 3 tubes. Finally we have a Siemens Valiant, which was originally designed by GEC. All tubes are 4000k, and all are Preaheat/SS, but the diffusers made the tubes look different to each other, especially notable on the SFB16's. In total, 17 tubes are used across these 7 bulkheads

Interesting lamp holder spacing there on the far right one. Have you got any inside pics of it

I'll grab it out tomorrow and grab a pic for you. The gear tray is a V shape, hence the lamp holders being like that inside. The design was made like this originally to fit the huge 8w ballasts from the days of GEC.

i have the GEC, i will dig it out tomorrw and post pictures of the monolithic open coil ballasts

I'll also post pics of the inside of the Siemens variant to compare and show just how much space is wasted in it.
