The smaller-scale Source Four jr uses the same technology that made the standard Source Four famous. That means unsurpassed imaging and beam quality. Compared to many conventional 650W and 1000W ellipsoidal spotlights, Source Four jr’s 575 watts still delivers an even brighter light and offers the flexibility of multiple HPL lamp options and interchangeble lenses. The Source Four jr is perfect for - but never limited to - smaller theatre venues, churches, schools, industrials, and any other application where affordability, space-savings and great performance are key.
Use this calculator to determine either the size of the circle of light, how far away you should place the light, or which degree of lens you should use. Put in two of the values and then hit calculate to find the third value.
Values can be in feet or meters, but both values must match.
