I use a really cheap reflector clamp shade and buy a full spectrum bulb. I got it at Amazon. You can put it anywhere you want and it's less than half the price of buying a new lamp. Bulbs are cheap as chips to replace too.
Redoing the downstairs and the painting desk I broke my bulb. I feel your pain, arrrgh.
I used this type of lamp for a long time. Nice and bright and fairly inexpensive. http://www.biglots.com/p/full-spectrum-table-lamp
