A dawn and dusk lighting system is a controlled illumination setup designed to simulate the natural progression of daylight, specifically the gradual increase and decrease in light intensity that occurs during sunrise (dawn) and sunset (dusk). This system is widely used in insectaries, animal research labs, greenhouses, and plant growth chambers to create a more natural environment for organisms sensitive to light cycles.

🔆 Key Features:

• Simulated sunrise (dawn):
  The lighting system gradually increases light intensity over a preset period (e.g., 30–60 minutes) to mimic natural sunrise. This helps reduce stress or shock that animals or insects might experience from sudden light exposure. Our system has option to chose dawn time from 10-120 minutes, i.e 10 minutes to 2 hrs.

• Simulated sunset (dusk):
  Similarly, light intensity is gradually dimmed to replicate sunset conditions, providing a more natural transition into the dark cycle. Usually it is again from 30-60 minutes. Our system has option to chose dawn time from 10-120 minutes, i.e 10 minutes to 2 hrs.

• Programmable light cycles:
  Users can typically program the photoperiod (duration of light/dark), along with the ramp-up and ramp-down durations to suit the biological rhythms of the organisms being studied. Our system has option to ramp-up or ramp-down from 10-120 minutes.

• Light spectrum options:
  Systems often include full-spectrum white light, and in some cases, infrared or UV options, depending on the species' photoreception sensitivity. We usually recommend to use candescent bulb of 40-100 watts depending on the required light intensity.

🐜 Application in Entomology:

• In mosquito or other insect rearing, dawn and dusk lighting supports normal circadian behaviors, such as mating, oviposition, feeding, and flight activity, which are often tied to light cues.

• It helps simulate crepuscular behavior, which is critical for species that are active during twilight hours.

🌿 Applications in Other Fields:

• Animal studies: Reduces anxiety and supports natural behavior in rodents, birds, or amphibians.

• Plant research: Mimics field conditions more accurately in greenhouses and growth chambers.

• Aquaculture: Helps regulate spawning and feeding rhythms in fish and aquatic organisms.

The dawn and dusk lighting system is essential for maintaining circadian rhythm fidelity and improving experimental realism in controlled environments.

Sunlight Mimicking System for Insectaries

The insectPRO Dawn and Dusk Machine is a fully automated, microprocessor-based lighting control system that simulates natural day–night cycles in closed environments such as insectaries, animal rooms, or plant growth chambers. Designed to mimic the progression of sunlight from dawn to dusk, this system helps maintain circadian rhythm integrity in research colonies.

With its Real-Time Clock (RTC) memory, the system retains all settings even after a power failure—ensuring uninterrupted operation without the need for manual reset.

🔧 Key Features:

• Fully automated microprocessor-based control
  Enables precise timing and repeatability of lighting schedules.

• RTC memory backup
  Retains all sunrise/sunset settings after power loss—no reprogramming required.

• Customizable dawn and dusk transitions
  Simulate sunrise or sunset transitions between 10 to 120 minutes (2 hours). For example, ramp light from 0% to 100% at 5:00 AM and reverse at 6:30 PM.

• Flexible scheduling
  Set sunrise and sunset start times as desired: 4 AM, 5 AM, 6 AM, etc.

• High load capacity
  Supports up to 1000–1500W. Easily connects multiple lighting sources or manages multiple insectary roomsfrom a single unit.

• Simple, user-friendly interface
  No tools required—push-button controls and intuitive setup make configuration effortless.
