How Energy-Efficient Are Vanray COB Lights Compared to Halogen Lamps?

Professionals in stage lighting seek powerful, cost-effective lighting solutions. This article addresses a key question: *How energy-efficient are Vanray COB lights compared to halogen lamps?* Efficiency, heat, and lifecycle are critical user concerns when selecting modern stage lighting.

COB Technology vs. Halogen: Understanding the Basics

- COB (Chip-on-Board) LEDs: Multiple LED chips packaged together for higher light output.

- Halogen Lamps: Incandescent lamps using halogen gas, common in traditional stage setups.

- Vanray COB Lights: Integrate advanced COB technology for optimal illumination and efficiency.

Energy Efficiency: Key Comparisons

Power Consumption

- Vanray COB Lights:

- Typical power draw: 100-300W per unit (source: (https://www.energy.gov/energysaver/led-lighting)).

- Up to 80% reduction in energy use versus halogen for similar lumen outputs (source: (https://www.energy.gov)).

- Halogen Lamps:

- Typical power draw: 500–1,000W per unit.

- Higher wattage required for equivalent brightness.

Luminous Efficacy

- Vanray COB Lights:

- Luminous efficacy: 90–120 lumens/watt.

- Halogen Lamps:

- Luminous efficacy: 12–22 lumens/watt (source: IESNA Lighting Handbook).

Heat Output & Environmental Impact

- Vanray COB Lights:

- Minimal radiant heat, reducing HVAC loads and risk of fixture burnouts.

- Contribute to lower ambient stage temperatures.

- Halogen Lamps:

- High heat emission; can raise stage temperature and increase cooling costs.

- Shorter operational lifespan due to thermal stress.

Cost Considerations

- Operational Costs:

- Vanray COBs offer up to 70% savings on electricity and air conditioning costs annually.

- Lifecycle:

- Average COB lifespan: 25,000–50,000+ hours (source: (https://www.signify.com)).

- Average halogen lifespan: 1,000–2,000 hours.

- Fewer replacements reduce labor and disposal expenses.

Light Quality & Control

- Vanray COB Lights:

- Superior color rendering (CRI 80+), consistent colour temperatures, and flicker-free performance.

- Smooth dimming capability down to <1%.

- Halogen Lamps:

- Naturally warm light, but limited color control and prone to flicker at low dimmer settings.

Key Takeaways

- Vanray COB lights are up to 80% more energy-efficient than halogen lamps.

- Reduce operational costs, environmental impact, and maintenance cycles.

- Deliver higher light quality and more reliable stage performance.

For stage lighting professionals, switching to Vanray COB lighting is a proven step toward efficiency and excellence.
