Awesome light
August 4, 2013
I bought this in 2010 from a local store and I have never been happier with any desk lamp. Ever. Anywhere you want this light, you can direct it--but the best part, if you want the light higher, it doesn't shine into your face as your work! I want to buy another one for my office. ASAP.
