Natatoriums are highly specialized spaces, and luminaires in this setting face several challenges. Perhaps the most significant challenge is that of corrosion. Galvanic corrosion is caused by using dissimilar materials in fixture construction and mounting. Corrosion is magnified by the presence of pool chemicals and high indoor humidity, which leads to condensation and material degradation. Stainless steel or aluminum construction is highly recommended for natatorium lighting, with the need for key hardware to be of similar materials. Additionally, heat and sun load in natatorium environments must also be considered during luminaires selection and placement.
Although direct illumination is more efficient, it often causes veiling reflections in natatorium environments, thereby reducing safety. As such, it should only be used in cases where the ceiling has low reflectance. Otherwise, indirect illumination is recommended to reduce glare and veiling reflections, improving the clarity of underwater viewing and related safety. Additional considerations when lighting a natatorium include increasing high angle illumination when daylight enters the space from low angled windows, heavy efficiency losses from coffered ceilings, fixture proximity to HVAC venting and skylights, elevated ambient temperatures, and the use of aimable optics to avoid maintenance issues. Fixture maintenance must be kept to a minimum, as they are often difficult to access.
Pool chemicals and moisture magnify corrosion, and lower mounting heights increases this corrosive effect.
Kenall will repair or replace qualifying luminaires rendered inoperable due to intentional abuse by vandals or accidental impact for the normal service life of the fixture.

Indirect lighting is superior in a natatorium and the IN9 Series is purpose built for this wet, hot, and corrosive environment. When positioned over the pool deck and aimed to project the light over the water, the fixture evenly lights the space and remains serviceable.
