GLS festoon at a Chinese festoon

This place used to be a pub, up until a couple of years ago when it changed ownership and became a Chinese restaurant. When it opened, I was surprised to see an old festoon set strung over the benches outside, with red, yellow and blue 25 or 40w GLS lamps. Must have been in the storage room, appear to be probably Deta branded lamps from the 90s. Sadly as they keep on going EOL they are being replaced bit by bit by monotonous white LEDs...
