Might be some sort of daylight reading lamp you got there.
Withoug a glass in front of the bulb you will get a little more light and if
it's not UV-shielded you should get enough UV to do a board....  But still,
a lightbox with quarts glass and 2x8w real UV will be faster.  The one we
have at the university takes 3 minutes.
