MY DIY VINTAGE BAYONET (BC) FLUORESCENT TUBE

MY DIY VINTAGE BAYONET (BC) FLUORESCENT TUBE


these are some photos of my diy 5ft 65w t12 fluorescent tube, this is a replica of the old fluorescent tubes that used to be produced during the war when the us bi pin design was to expensive to adopt until later so used the exising incandescent lightbulb bc cap technology on fluorescent tubes instead, due to the amount of fixtures produced in this time bayonet capped tubes were avaliable until the 1980s and you could also get bc to bi bin adaptors, there is much more info on these tubes if you search L-G,
Anyways this tube started of as a standard 5ft 65w t12 daylight tube from the 90s id guess,
it came out of and old sign i was servicing, it worked but the cement holding the end caps on had come loose, so i thought of removing the caps and grafting permanent bc caps onto the ends as finding bc capped tubes here in new zealand is very very hard! although every once in a while you will see and old bc fitting around,
so i snipped the tips of the caps off which is where the wire inside is attached to the cap, the caps then came off, leaving enough length of wire to add (by twisting) more wire to increase the length, i then smashed a few bc incandescent bulbs leaving two nice bc caps, i then drilled two tiny holes through each metal contact on the bc caps to feed the wires from the tube through, then i soldered each contact, snipped the remaining wire off and heated the solder again to smooth over the oval contacts on the bc caps, and to hold the caps to the tube i used heat proof loctite glue, very strong and clear,
And this is the result!!
i was very pleased with the outcome, it looks very very factory and you wouldnt at all know that it was originally a bi pin tube, unless someone in the know read the label lol,
and since i dont yet have a bc fitting to test it you can see by the photos my igenious was of using the 1970s thorn popular pack in my workshop at home! haha

That looks cool, you did a great job with this. Ill have to salvage dead BC and try this one day, Ive got a few philips 20wT12 with loose ends too...

Bring back Fluorescent and SOX Streetlights. Keep magnetic ballasts.

hey, yes we had bc tubes in new zealand, i almost bought one from a guy who was selling a twin bc fitting with a brass end bc tube from a new zealand site, but he wouldnt ship!!! but in small rural towns you will still see the od bc fitting with a t12 in it but because of the long sleeve covering the caps and holders you cant see if its a genuine tube or a bi pin hamp with bc adaptors, i remeber these bc fittings when i was a kid looking up at old neglected fluro fittings wondering why the hell there were bayonet holders dangling out, i must get a photo of these old bc fittings next time im on my way to tauranga, but yea we did have bayonet fittings and tubes just like you guys in the uk

5 foots 80w BC tubes were common in the 50s I remember these in use where my father worked and they had a cover to shield the ends which were clear before the cap, it was thought UV would be produced and cause sore eyes, later the cap was made to extend the diameter of the tube and no clear area there. Also BC caps were on circular lamps made by Brightlights as well as the bi pin.

Interested in the history of electric lighting and incandescent in particular and neon glow lamps.
