Which light wattage is best for exposing photoresist film for sandcarving?

An important factor in choosing the right light to expose photoresist film is the wattage of the bulb. In the early days, we operated with 15-watt bulbs, but later found that 20-watt bulbs work better. You can find that information directly on your light bulb. This is good to know if you need a replacement bulb.
