It's not a style I've seen before?

If you recognise it, is it still available?

Thanks

Looks like a linear lamp to me, possibly a low energy mod rather than an actual halogen. How long is it?

It is roughly 700mm (I didn't have a tape measure to hand)

There are approx 30 tiny lamps all linked together

I wondered if it was from an instrument cluster, or to edge illuminate a display, are they lots of ELV in parallel or is it a series string summing to mains voltage ?

I couldn't see a driver so I assume it's series

This is used as a picture light with two thin arms and this between them it's rather minimalist (I quite like it)

I guess the modern equivalent would be the LED ribbon, though for expensive artworks, I can imagine concerns about both UV damage, and good colour rendering, those being two things the white LEDS are not famous for. If series wired I wonder if it may be like the self healing christamas lights where one or two lamps can fail open, then break over and the rest keep running.
Is there a need to find a spare ?

Since the lamp is on the stairs, could they be Landing Lights?

I've never seen a lamp like that before. It seems to have 32 little grain of wheat bulbs in the tube. Presumably if it runs off 240 Volts they will be series wired at 7.5 Volts per bulb. If one fails they all go out. A poor design. Surely it would be possible to make a mains rated linear lamp with a single filament for that use, but perhaps this is made to be very compact in diameter. Are there any markings on the end caps? What Voltage appears on the two supply terminals of the fitting?

When the lamp eventually goes "ping" it may be conversion time.
