ETC Source 4 575W Lamp Required
Source Four jr 50 Degree LensThe power of Source Four in a compact and economical size! 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 the criteria.
