It's a slight update on the classic fibre optic spray or flower light, but with an upgrade from a halogen lamp to an LED one. The classic fibre optic displays pre-date LEDs and tended to use a tungsten or metal halide light source. The colour and effects are based on rotating disks, and there used to be very complex fibre optic signs that mapped the fibres onto the disk assembly with multiple concentric effect layers These days, the fibre optic light sources have gone in the direction of high power RGB LEDs. The downside of that is that you just get a solid colour change without the sweeping effect of the disk. You can also get patches of primary colours on the fibres due to the position of the red, green and blue LED emitters. The main advantages of the LED sources is that they run much cooler and use significantly less power. There have been interesting systems using rotating PCBs with multiple coloured LEDs to emulate a rotating disk. This version is the classic 12V AC base with a synchronous motor, but the tungsten bulb has been swapped for an LED one. The unit is visually brighter, with very vivid colours due to the cold white light source. It makes the colder colours like blue much brighter. If you have an old fibre optic light like this it may be viable to upgrade it with a suitable LED bulb. The smaller units like this one tend to use an MR11 bulb (Metallised Reflector 11/8ths of an inch diameter). Some larger units use an MR16 bulb. My first fibre optic lamp had very slender glass fibres and a candle bulb for illumination. The glass fibres were notorious for breaking and giving you painful glass skelfs. You may be able to find some of the retro fibre optic flowers on eBay. If you enjoy my videos then the easiest way to support the channel is to subscribe for more good video content.
