Came across these small LED lights called Luma Cube so i purchased 3 and they are very small and extremely bright for their size.
Unfortunately they only have a battery life of about 20 minutes on full power so i added a USB charger and i can run them for as long as i like.
They have 10 brightness settings from bright to blindingly bright.
Only one problem is they get hot and i mean ####ing hot.
