Hi Sean,

Based on my testing of this type of UV tube (i.e. sprial UV BLB tubes) an array of 20 watt tubes should provide enough UV radiation to print with UV sensitive processes.

For best resuls place the bulbs as close together as possible, and plan for a bulb to printing frame distance of no more than about four inches..
