Light-Concentrating Artificial Solar Lighting

Artificial Sunlight for High-Irradiance and High-Illuminance Testing

The XELIOS XG-Series Super Spotlight concentrates artificial sunlight for evaluation and testing. EFSS models are specified for 1 sun (1,000 W/m²) irradiance, while AFSS models are specified for 100,000 lux illuminance. Select the model group based on the measurement conditions your application requires.

The standard Super Spotlight configuration is designed for either 1 sun or 100,000 lux, not both at the same time. If your test requires both conditions, contact SERIC to discuss a fully customized system.

XELIOS Super Spotlight at a Glance

Start with the light measurement your test requires: irradiance (W/m²) or illuminance (lux). These are different measures and should not be treated as interchangeable.
For Irradiance-Oriented Testing
1 sun (1,000 W/m²)
Models: XG-100EFSS / XG-500EFSS
At the stated 1 sun condition, the listed EFSS models provide approximately 60,000 lux of illuminance.
For High-Illuminance Evaluation
100,000 lux
Models: XG-100AFSS / XG-500AFSS
The listed AFSS models are configured for 100,000 lux of illuminance.
The standard configuration cannot provide 1 sun and 100,000 lux simultaneously. Contact SERIC if both conditions are required.
This is a selection overview, not a complete numerical specification table. Confirm test area, irradiation distance, light distribution, and other conditions with SERIC.

    • UV-resistance testing of products and materials.
    Contact SERIC to confirm the appropriate configuration and test conditions for UV-resistance applications.
Other applications may include natural sunlight simulation; suitability should be discussed in the context of your test requirements.

Key Features

High-Intensity Light
Concentrated artificial solar lighting for tests requiring high light intensity.
High-Energy Light
A concentrated light source for evaluation applications requiring high light energy.
Near-Parallel Light with the Applicable Filter
Near-parallel light can be produced when an ASS, ESS, or BSS transparent filter is used.
Filter suitability and supplied configuration should be confirmed with SERIC. The transparent filters must not be represented as included by default.

Application Example — Mizuno WAVE LIGHTREVO

Surface Temperature Evaluation of Baseball Cleats

SERIC’s artificial solar lighting was used in Mizuno’s WAVE LIGHTREVO shoe surface temperature visualization experiment. Artificial sunlight was directed onto baseball cleats indoors, and changes in surface temperature were recorded using thermography.

The experiment used an XG-500EFSS at 900 W/m² under the conditions described in the case study. This is a test-specific setting, not a general rated specification for every Super Spotlight installation.
The model is referred to as XC-500EFSS in the Japanese market; the current English product page states that its performance is the same as XG-500EFSS.

  • The standard concentrating-type unit cannot provide 1 sun (1,000 W/m²) and 100,000 lux simultaneously.
  • Measurements for XG-100AFSS/EFSS are described as five-point measurements according to SERIC’s internal standards.
  • Measurements for XG-500AFSS/EFSS are described as 17-point measurements according to SERIC’s internal standards.

Discuss Your Irradiation Requirements

SERIC can review the intended application and discuss lighting adjustments or a custom configuration. Providing the following details, when available, will help clarify your requirements.
  • What product, material, sensor, or system will be tested?
  • Is your priority a target irradiance (W/m²) or illuminance (lux)?
  • What irradiation area and working distance does the test require?
  • Are there installation or test-environment constraints?
  • Are specific spectral or filter conditions relevant to the application?

These are preparation questions, not a form or a requirement to provide every detail before contacting SERIC.

Frequently Asked Questions

  • Can a standard Super Spotlight provide both 1 sun and 100,000 lux?

    No. A standard concentrating-type system is configured for one of these conditions, not both simultaneously. If both are required, contact SERIC to discuss a fully customized device.

  • Which models are listed for 1 sun irradiance?

    XG-100EFSS and XG-500EFSS are listed for 1 sun (1,000 W/m²) irradiance. Under this condition, the illuminance is approximately 60,000 lux.

  • Which models are listed for 100,000 lux?

    XG-100AFSS and XG-500AFSS are listed for 100,000 lux illuminance. This is a different target from 1 sun irradiance.

  • Can SERIC adjust the irradiation conditions?

    SERIC reviews the intended use and irradiation requirements before shipment and can discuss adjustments or customized equipment. The suitable configuration depends on the application and conditions.

  • Which Super Spotlight models are mentioned for UV-resistance testing?

    The current Super Spotlight product page lists XG-100BFSS and XG-500BFSS as examples for UV-resistance testing of products and materials. Contact SERIC for applicable model specifications and test conditions.
