This is not your average desk lamp. The quality is phenomenal. The price is high, but it's worth it.I've always used relatively inexpensive (~$20-$30) desk lamps. My reasoning boiled down to: a lamp is a lamp. I recently had an adjustable LED one with multiple light color temperatures. This TaoTronics lamp outperforms it in every way.You can actually see the difference between the color temperatures and none of them are overly harsh or otherwise displeasing. The 3000k is very similar to a true incandescent bulb, the 4000k is very close to true sunlight coming in from a window, and the 5000k is much cooler. My eyes get strained easily, but this lamp has improved that. I think the diffusing panels over the bulbs help by softening the glow.I really like the 45 minute timer function. I often stay at my desk for hours without taking a break. I've been using the timer to remind myself to get up.
