Daylight lamps

I have a single daylight lamp, originally purchased as a light therapy device to improve mood during the winter months. I find the light very pleasant; I mostly used this lamp when I was writing my thesis last winter. It is not decorative, it’s basically a real block (definitely bigger than a desk lamp), but effective, and as I said, suitable for work. Unfortunately, I can only tell you that it was from Philips, but not how expensive it was.
