What’s the advantage of lamps with multiple wattage settings?

Lamps with multiple wattage settings provide increased control over emulsions with very short exposure times. In essence, by reducing wattage and increasing exposure time, the operator has a greater margin of error. Where a one-second difference might be critical on a highly sensitive emulsion exposed at a 6K setting, that single second is far less critical when exposed at the 3K or 1K setting. NuArc’s System 631 is a production-proven light source that gives the operator the ability to change the wattage of the lamp by selecting 6K, 3K or 1K. It's an ideal choice for those who deal with extremely fast emulsions.
