which UV bulb for retr0bright treatement?

[Special K]

I have been reading a lot of articles about the retr0bright (retr0brite/retrobright) process and they all mention that you can use either natural sunlight or a UV bulb.  The problem is that none of these articles ever say which bulb to use.  Can someone provide a link to one they have personally used that worked?  What about this one:

Can I just screw this into a desk lamp socket and then suspend it over the container I have my plastic pieces in?

Here's a different form factor:

Or would something like this work better:

Either of those lights would be fine. You could also go the cheaper route and use some of that free sunlight

sunlight's especially powerful now that we got all this snow.

Yes, I realize sunlight is an option.  The problem is that it can be very hit or miss this time of year (mostly miss over the last couple weeks here), plus I live in an apartment with a covered balcony that doesn't really get much sunlight due to the building's orientation.  An indoor setup with a UV lamp would be much more reliable.
