Awesome light. Expensive, but worth it
The light itself is very wide - I measured it to be about 50cm. The diffused light it emits makes it perfect for illuminating whatever is beneath it from all angles, so it's great for activities like painting models where shadows can be a pain. It's also super bright, so much so that I always put it on the lowest setting while using it (there are 4 brightness levels). I don't know this is definitely the case, but the tone of the light feels like sunlight - when I have it on during the night I feel like it keeps me awake/alert.
