4 Pack 48” T-12 Industrial Fluorescent Black Lamps
Pricing includes a $30 over packing fee to ensure the bulbs make it to you intact. These are fluorescent tube bulbs made specifically to output high intensity UV light. The bulbs are much different than a novelty “black lamp” and those types actually will not work for exposing screens. These bulbs put out a lot of UV light for screen printing emulsions to cure by. If you want to build your own exposure unit at home these bulbs will make the time worth it. These are the same bulbs that come in professionally built industrial black lamp exposure units made for screen making. 40 Watt bulbs.
