What Beam Angles and Color Temperatures Are Available in Vanray COB Lights?

As a professional in the stage lighting industry, understanding the options for beam angles and color temperatures is crucial when selecting Vanray COB (Chip-on-Board) lights. This article addresses the most common technical queries for Vanray COB’s lighting capabilities, focusing on available beam angles and color temperatures—two key parameters impacting creative flexibility and show quality.

Beam Angles in Vanray COB Lights

Definition:

- The beam angle determines the spread of light emitted, affecting both coverage and intensity.

- Wider angles cover more area with less intensity; narrow angles provide focused, high-intensity beams (USITT, Lighting Handbook).

Available Beam Angles:

- Narrow (10° – 20°):

- Ideal for spotlights, gobo projection, and emphasizing stage details.

- Used in key accentuating performances or highlighting objects (ETC Source Four Reference Guide).

- Medium (25° – 40°):

- Offers balance between coverage and punch.

- Common in washes, front lighting, and stage coverage.

- Wide (45° – 60°):

- Best for area washes and general illumination.

- Suitable for cyclorama and set lighting, minimizing shadow edges.

Typical Vanray COB Offerings:

- Multiple beam angles are available per fixture model.

- Many Vanray COB models support interchangeable lens options for on-site customization.

Color Temperatures in Vanray COB Lights

Definition:

- Color temperature, measured in Kelvin (K), changes the mood and atmosphere of a stage.

- Lower values = warmer (“tungsten” look); higher values = cooler (“daylight” look). (IESNA Lighting Handbook, 10th edition)

Available Color Temperatures:

- Warm White (2,700K – 3,200K):

- Replicates traditional halogen stage lamps.

- Popular for theatrical, opera, and musical designs requiring warmth.

- Neutral White (4,000K – 4,500K):

- Offers a balanced, natural appearance.

- Used in television, conferencing, or mixed-content performances.

- Cool White (5,600K – 6,500K):

- Mimics daylight, enhancing crispness and color rendition.

- Best for concerts, exhibitions, and when matching other daylight-balanced systems.

Vanray COB Color Mixing Features:

- Many Vanray COB fixtures offer variable color temperature technology or tunable white drivers for in-situ adjustment.

- This flexibility enables quick adaptation to varying lighting design requirements.

Selecting the Right Beam Angle and Color Temperature with Vanray

- Consider throw distance and coverage needs:

- Short throws benefit from wide angles; long throws may require narrow beams for intensity retention.

- Match stage and event atmosphere:

- Warmer temperatures for dramatic or intimate settings.

- Cooler temperatures for modern, energetic events.

- Check fixture spec sheets:

- Always verify model-specific offerings as per Vanray’s official technical documentation.
