Light Series 4 - HID

A. This space is a middle school basketball gymnasium.
B. The purpose of this lighting is ambient lighting. It is used for large volume and tall ceiling types of places.
C. The luminaire is metal with a plastic covering. There are more than one HID's in the luminaires.
D. The effect of the light source in the space is a bright all over intensity spread to illuminate the surface of the court as a whole. The key is to have sufficient overlapping of light in order to reduce contrast and keep the court surface looking smooth.
E. The effect of the light on colors is somewhat reddish. The blues on the court look really muted and even greyed out. The reds in uniforms really stand out which is one good thing about having a cool color temperature.
F. The levels of illumination are appropriate. There is a nice spread of illumination across the court. Although there is a glare created from the luminaires on the floor which could be a problem from the basketball players concentration.
G. Observations and Recommendations:

• Using a lower intensity light may reduce the glare from the luminaires on the basketball court.
• Use some wall washing to reduce the contrast from the court to the walls to the ceiling. The ceiling seems the brightest area of all.
• Maybe use some task lighting down where the judges and score keepers will be so they don't have to just rely on the ambient lighting from the HIDs.
