Old BC type fluorescents « on: October 30, 2017, 04:47:26 PM » Author: highjon
Hi. What do you guys think of these old GEC fluorescents that I managed to salvage from a job im rewiring.. there are 8 complete units all working, with BC type 5foot tubes. Very art deco, taken from a diamond house in Glasgow sitting above the suspended ceiling. Got a few spare components also... nice

These are nice... How do you install bc type bulbs though? Do the end flip outward or something?

I like my lamps thick, my ballasts heavy, and my fixtures tough.

The white metal covers come off over the end caps, just a screw holding it in place, to reveal Bayonet cap sockets on flying leads....neverseen this before myself.  I believe the shop got refitted in 1952... see pic

Lamps range in age from the 1960s to mid 80s (Thorn EMI is from between 1984 and 1987)

You have correctly identified these lamps as having been introduced in the 40s, but they in fact remained in production until 1992. Since then, installations have been maintained with ‘composite’ lamps, in which a standard Bi-pin ended tube is fitted with BC adaptors at each end.  Indeed there are still a few of these luminaires in operation on London Underground!

What a nice find I just hope they all work or at least some of them if they are that old don't forget to check they are for 240 volts 50 cycles and not some non standard supply I know you know this but it never hurts to mention it

I’ve seen these on eBay. I only have one BC tube currently but that is quite an eye opener. I’m no stranger to Glasgow either...
