Here's a project That I'm very happy with. It required many attempts in resin treatment, but it eventually had an amazing effect.
So far I've made two copies. The structure is made of oak wood and stained epoxy resin. The stand is walnut wood. The led lamp itself gives quite strong light, so I suppressed it with a yellow filter.
The effect of lighting a dark room is amazing. Very warm light reflects on the wall and shines through the resin layer.
Here's a video of my lamp posted on you-tube: https://youtu.be/XKS5xn-xjKc
