201 Daktronics Dr. PO Box 5128 Brookings, SD 57006-5128 tel 800-325-7446 605-692-0200 fax 605-692-0381 www.daktronics.com DF -02 7 6 6 The lighting analysis also shows most of the illumination is directed to the field with limited amounts of light falling on other areas off the field. The highest illumination level, 0.05 footcandles, off the field is located at 250 ft at an angle of 40 degrees from the sign face. To put this level into perspective, that is only 5% of the light of a single wax candle viewed one foot away. This level is also only 10% of the average parking lot lighting (0.5 footcandles) as documented on the enclosed ‘Dark Sky Recommended Lighting Levels for Exterior Lighting’ document. Additionally, as a comparison, a local residential roadway’s average illumination is 0.4 footcandles while the average lighting on an expressway is 1.2 footcandles. Finally, as stated above, it’s important to emphasize the proposed scoreboard lighting will not have any lighting impact to Lake Valentine road and the neighboring residential properties. Finally, it is important to note the illumination levels are only representative of Daktronics LED scoreboards. Other digital display manufacturers may use different LEDs which have different light emissions. Daktronics is committed to providing digital displays that adhere to the regulatory environment, working closely with our customers for a responsible approach to the market. Please let me know if you have any questions or concerns. Sincerely, Daktronics, Inc. Angela Bailey Signage Legislation 605-692-0200 i Please note, while the sign’s brightness during daylight hours would be almost always incidental, there may be times in which the sign would produce illumination levels above ambient light during such hours. Examples when such an occurrence could happen would be during a very dark and stormy day. It is important to note, however, that the sign is equipped with a working photo-sensor that automatically adjusts its brightness based on ambient light. The photo-sensor adjusts the sign’s brightness to lower levels, preventing the sign from appearing overly bright during those rare occasions where its brightness would exceed ambient light. ii Also note, the illumination levels cited take into account a height above ground level of 15 feet and provide the illumination which will be measured by the testing meter located 5 feet above ground level.
