Originally developed for spray-down use in caustic chemical rooms and clean-areas, the Crawford Series is corrosion-proof and durable.
Housings are available in polycarbonate, acrylic (PMMA), or glass, offering options for different corrosion-resistance and impact resistant requirements; polycarbonate being the toughest but least resistant to chemicals, whereas toughened glass is the most corrosion resistant, but less durable. Acrylic (PMMA) offers a compromise between glass and polycarbonate.
Available in 2ft, 4ft, and 5ft housings, integrated optics ensure light can be directed where needed.
Suitable for a wide range of applications, including livestock farming (including pig rearing, and dairy), chemical stores, swimming pool plant rooms, pump rooms, and industrial kitchens.

DESIGN FEATURES
Linear lights designed for PURPOSE
Impact Protection: Polycarbonate diffuser provides an impact protection score of IK10 proving it to be a durable product. Cable Wiring: Cable entry uses a quick connector system. Parallel and series installation is possible with the Crawford Series. Ingress Rating: IP69K corrosion resistant provides a product capable of performing in various corrosive environments. Integrated Optics and Directed Light Output: Across all three fitting lengths (2ft, 4ft, & 5ft) the Crawford Series has lumen output of 141lm/W to 148lm/W. Corrosion Resistant: PMMA, GLASS, or polycarbonate housings, with stainless steel fixtures and fittings, provide a product capable of performing in various levels of corrosive environments.
