ETC Source Four Leko, 50 Degree

The ETC Source Four Leko (Source 4) is a professional ellipsoidal spotlight built for crisp stage and architectural lighting. This 50 degree version is a practical choice for wide-area coverage, making it well-suited for front light, general washes, and longer throws where you want clean shutter cuts and reliable focus.

These ETC Source Four Lekos were used in a rental inventory. They show cosmetic wear and are in good working condition.

Please note that these items may have a longer lead time.

Rated up to 750W and designed around the super-efficient HPL lamp, the Source Four pairs a faceted dichroic reflector with optical-quality lenses for a bright, even beam. Because the reflector removes 90% of IR heat from the beam, gels, patterns, and shutters tend to last longer, and performance spaces stay cooler.

Optics and Focus Control

The Source Four uses a standard ellipsoidal head with an interchangeable lens tube system (19, 26, 36, or 50 degree). The rotating barrel (plus or minus 25 degrees) helps you keep shutter cuts level without having to reposition the entire fixture, and the three-plane stainless-steel shutter blade assembly supports precise shaping for doors, scenery, and masking.

Built for Real-World Inventory

Tool-free lamp adjustment speeds up maintenance and focus, while the insulated rear handle and rugged die-cast aluminum construction are designed for frequent handling. It also supports Dimmer Doubling (North America only) for greater circuit flexibility in compatible dimming systems.
