Worst beams – show me your Everest if ugliness

I don't expect the beams to be perfect, but there are some lights that are simply off-putting with the beam shape, light quality, artefacts… Like this abomination, being a 3×18650 light 🤪, with awful 5mm LED and having resistor as a driver 😁 Supposed to be work light using drill driver batt pack, but it's pretty useless, being 100 times worse than simple Nitecore TUBE keychine flashlight. Just blah…

You're lucky that my phone camera is fat from the top ones and on the photos light looks way less dead pale blue than in reality, also a big part of distortions, small lines, weird patterns is smothered by the phone software.

What are yours beam nightmare flashlights?
