Compact ellipsoidal spotlight (ERS) by ETC with plano-convex lens and HPL lamp (max. 575 W); compact version of the Source Four.
Overview
The Source Four jr (also "Source Four Junior" or "S4 jr") is an ellipsoidal reflector spotlight (ERS, colloquially "Leko") from the US manufacturer ETC (Electronic Theatre Controls). It is the more compact and more affordable version of the larger Source Four and uses the same basic technology of a dichroic reflector and ETC's characteristic HPL lamp. Like all profile spots, it produces a hard, sharply defined light field that can be shaped using four built-in shutters, as well as gobos and an iris diaphragm. It is a fixed profile spot, not a followspot.

| Device Type | Ellipsoidal Reflector Spotlight (ERS) |
| Light Source | HPL lamp, max. 575 W |

The fixed lens tubes are available in field angles of 26°, 36°, and 50°; in addition, there is a zoom version with a range of 25° to 50°. Unlike the large Source Four, the jr is not available with the narrow 19° or 14° tubes, making it unsuitable for very long throws.
Use on Set
The Source Four jr is used where a contourable, hard beam of light is required but space is limited: small stages, studios, trade show and event construction, as well as theater and TV applications. Gobos can be used to project patterns and textures, and the shutters allow for clean cutting of light at edges (e.g., to precisely define image borders, curtains, or backgrounds). Compared to the large Source Four, the jr is lighter and more compact, but offers fewer angle options and a slightly simpler shutter and housing design.
