Love love love. OK absolutely LOVE the Chloe Dauphine desk lamp by Lumina. I personally have 2 of them in my office, one on each desk. Sure it's a bit pricey, and if it's out of stock, the lead time can get high. But, it gets the job done and takes up very little space, does not tip over and the head does not get hot. (You have to watch out for that with the halogens.)
And a good alternative is the lesser expensive yet classic Artemide Tolomeo series. There's a few sizes. Versatile.
But check this out... The minis just came out IN COLOR. Seriously. I am in love with the colored ones.
P.S. Artimide is running a sale -- 40% off the month of April on selected products. The colored minis are not on sale, but many of the other Tolomeos are.
