I am about to build an exposure unit with a vacuum lid using 24" black lights bulbs...My question is how far apart should the bulbs be spaced...I am planning to have them 2" below the glass....I am going to build the box so that I can expose up to 23 x 31 screens...Thanks...If someone could measure there Vastex 2331 or Nuarc first light unit that would be awesome....Thanks
