Circadian Lighting
for 24-Hour Alertness and Shiftwork

BIOS SkyBlue™ Dynamic Lighting provides biological lighting designed to support around-the-clock operations where focus, alertness, and circadian health are essential—even after dark. Using a single-channel control (Bio-Dimming™ module) or two-channel system, SkyBlue™ Dynamic adjusts both intensity and spectrum, transitioning from high-melanopic daytime light to lower melanopic evening light with just a 500K shift.

Unlike “dim-to-warm” systems, this solution supports biological needs without dropping to unproductive CCTs like 2700K—making it ideal for shift workers and facilities where people need to stay awake and alert.

Applications: Spaces in operation overnight, after 7pm and before 7am

What is SkyBlue™
Dynamic Circadian Lighting?

SkyBlue™ Dynamic provides high-melanopic daytime light enriched with 490nm SkyBlue™, and gradually dims to a biologically appropriate evening spectrum with no 490nm—but maintains visual brightness and productivity. It’s middle-of-the-road circadian lighting: biologically maximized for day without going too warm or visually dim at night.

SkyBlue™ Dynamic is ideal when 2700K lighting is too warm for the task, but the circadian system still needs to rest. Perfect for 24-hour environments where people don’t sleep, but do need support for both day and night circadian cycles.

Why Choose BIOS SkyBlue™ Dynamic?

Typical “tunable white” or “mood lighting” systems shift color temperature for visual preference, not biology. BIOS Dynamic Lighting is engineered to:

  • Provide high daytime melanopic content (490nm)
  • Smooth dim-to-evening spectrum with narrow CCT shift (500K)
  • Support biological alertness and rest cycles for shift workers
  • Avoid productivity dips associated with overly warm CCTs (e.g., 2700K)
  • Outperform decorative dim-to-warm systems in health impact

Simple One-Channel Control with BIOS Bio-Dimming™

BIOS SkyBlue™ Dynamic Circadian Lighting can operate using standard single-channel dimming, making it easy to deploy in existing infrastructure. When paired with the BIOS Bio-Dimming™ Module, the system intelligently controls both intensity and spectrum together to meet daytime and evening circadian goals.

Single-Channel Operation:
  • Requires BIOS Bio-Dimming™ Module
  • Seamlessly dims from day mode to night mode
  • Removes 490nm SkyBlue™ as light dims
  • Maintains task-sufficient CCT without sacrificing brightness
  • Compatible with all standard protocols: 0-10V, DMX, DALI, ELV & Wireless
