This is a faulty ground recessed uplighter that was sent for our exploration by Douglas.
It's a classic example of premeditated landfill, with no replaceable lamp and a sealed case to try and stop water getting in.
They are often mounted into a buried enclosure to ensure that anyone who works on them has to kneel on wet ground and fumble in stinky water to try and make a waterproof connection onto a cable that gets shorter every time a fitting is replaced. They're usually powered from panels where all the RCDs/GFCIs have been bypassed to "fix the tripping issues". (Not a good thing.)
If working on this type of light it's VERY important to ensure power is properly isolated. That can sometimes be difficult when they are fed from random panels and are powered but not lit. Water and electricity are a bad combo for humans.
You can see this type of light littering the pavements of cities and "architectural" areas. They either shoot light pointlessly into space while dazzling pedestrians, or put blotchy skidmarks of light up the side of buildings. They are notable for flickering gently as their corroded LEDs light the internal drops of water on their lens, and occasionally emitting steam from their submerged electrical connections.
You may have noticed I'm not a fan of this type of light. But they do have their place if used as low intensity marker lights, with low voltage power supplies and easily replaced cables going to a nearby pillar.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
