Because there are no formal standards for lighting in cleanrooms, contractors and operators must have a thorough understanding of the different types of lighting, fixtures, and installation options available and consider which one will best suit the level of cleanliness required in their critical environments. Here are a few supplier options.

Lighter-weight fixture offers flexible ceiling placement
The Bio-Seal is the most technically advanced grid and flange cleanroom troffer available. It is certified for Class 100 (ISO 5), IP66, NSF, and Class 1 Division 2 spaces. The standard seam-welded aluminum body radiates lamp and ballast heat to provide extended transformer life and higher lamp lumens. Its 60 percent lighter weight does not burden a sheet rock ceiling. The one-piece gasket system is dust tight and withstands 26 gpm hosedown without leakage. The fixture can easily provide 30,000 lumens from 6-T5HO lamps. Options include SS doors and housing, surface mounting, and top access re-lamping.

Standard and custom cleanroom lighting systems
Choosing cleanroom lighting fixtures that won’t leak, introduce toxicity or corrosion, add excessive heat, or create potentially unsafe conditions is crucial to each cleanroom environment. Innotech Products offers a quality line of cleanroom lighting such as laminar flow-through, tear-drop, and contaminant-proof sealed housing fixtures, as well as top access, recessed, surface, corner, and UV-shielded lights for clean applications. The fixtures come in standard and custom sizes to fit virtually any ceiling system style. To speak to a cleanroom specialist regarding these and other cleanroom needs, call (888) 270-0458.
NSF-certified lighting suitable for harsh environments
LDPI Lighting’s 376 Series wet/damp fluorescent light fixtures have recently been tested and certified by NSF (National Sanitation Foundation) International to NSF/ANSI Standard 2. The fixtures are designed for use in a variety of areas where harsh conditions exist, such as food and beverage processing facilities, packaging and distribution centers, refrigeration rooms/freezers, cleanrooms, and other areas where extra sanitation precautions are needed. The lights feature a poured-in-place polyurethane gasket and latch that provides continuous positive gasket contact while sealing enclosures from the most hostile environments. Durable components include stainless-steel mounting hardware and a corrosion-resistant non-metallic enclosure. A unique mounting system, which eliminates the need for drilling holes through the housing, reduces installation time. Mounting brackets are designed for narrow and standard lamp housings, and an optional 45° mounting bracket is available.

Light-emitting diode bulbs replace direct incandescent systems
LEDtronics’ latest generation of PAR20 LED short-neck light bulbs replace direct incandescent bulbs, combining advanced light-emitting diode (LED) technology, standard 25 mm Edison screw bases, and a light-optimizing design to produce vivid light. The LED bulbs are available in three light-emitting angles: 15°, 20°, and 22° and in 120 V AC. Other voltages such as 12 to 240 V AC or DC are available to qualified customers. They are well suited to small spotlighting tasks in track or recessed lighting fixtures or high-hat ceiling spotlights. With a power draw of only 2.5 W, energy savings add up over time. Standard colors available are Warm White and XWarm White (3,000 K), Cool White (7,000 K), Super Red (633 nm), and Aqua Green (525 nm).
