Sad lightboxes make me happy

How does the kelvin and lux ratings of a light relate to how effective that light will be for treating SAD?

I have a 10,000 lux 7000 kelvin * lightbox that I use in the winter. However a new job with early mornings means I'd rather have somthing to use at my desk. I've found lots of desktop sad boxes but they're all huge and obviously alien to the workarea.
I've also found a supplier for mini flurescent tubes that fit in a anglepoise type lamp. 1700 lux and 6700 kelvin.
Does the difference between 10,000 and 1,700 lux means I'd need to use it for five times as long?
How important is the kelvin rating of the tube?
* I may be wrong on the kelvin rating of the lightbox I already own...
