I try to stay away from those LED rigs... For one, it is hard to figure out what kind of output you are getting, and how much, etc. For another, most are just the ugly bright purple (which would look pretty funky on a desk!).

There is a really simple solution. You can just use ordinary CFL bulbs that you can get at Home Depot, Lowes, Walmart, etc. These screw easily (like a normal bulb!) into an ordinary desk lamp, and they give off ordinary (!) light. These are especially good if you just have a few plants. Just make sure you get the right bulbs- 6500K, and 100 watt equivalent (somewhere around 17 real watts).

Just to give you a picture, here are some of the bulbs that I use:

That's perfect. I'll definitely get one! Thanks! :)
