Cressida – CSF

Cressida LED

The Cressida range of IP65 dust and waterproof features luminaires are designed to protect the integrity of a cleanroom. The total sealing of the luminaire maintains the integrity of the cleanroom, and protects against infiltration of particles and airborne bacteria and ensures that contaminants, toxicity or corrosion will not enter the cleanroom environment via the luminaire or cause airflow disturbance. All Davis Lighting cleanroom luminaires have been tested for cleanliness capability with cleanroom classifications in accordance with US Federal Standard 209E. Cressida has joined the ranks of a number of Davis’ classic luminaires, embracing LED technology to deliver energy and cost savings in both the recessed and surface mount models.
