there was a recent thread on aus.electronics USENET group about this.
search subject "UV Light Box Plans" in 
 http://groups.google.com/groups?num=25&hl=en&group=aus.electronics&safe=off&start=25

For my UV source I use 400W standard HID mercury vapor flood lamp. 
Exposure is 90 sec at 400 mm distance from the lamp. 175 W would be more 
suitable.
