A Cleanroom downlight specifically designed to provide laboratory illumination from a sealed, smooth and cleanable aperture. The low cutoff angle reduces glare reflected on monitors and glossy surfaces. These gasketed flush lensed luminaires are designed to seal the ceiling and prevent the entrance of contaminated air into the cleanroom. The CRD series is capable of up to 5000 lumens, and provide full range dimming to 1%, offering the flexibility desired by laboratory staff. These fixtures feature an option for 97+ CRI with very high R9 value, providing improved color recognition.
