1.4 Product Overview
Daktronics outdoor LED scoreboards are part of a family of scoring and timing displays designed to
offer easy installation, readability, and reliability. Microprocessor control assures consistent operation
and accuracy.
Featuring large, highly visible PanaView™digits 15, 18, 24, and 30" tall, the boards use light emitting
diodes to power the scoreboard display. (Light emitting diodes, or LEDs, are tiny, solid-state
components that use a semiconductor to transform electrical current into light; they are high-intensity,
low-energy lighting units.)
Because of their LED technology, the scoreboards consume little power, some barely more than a
household lamp. Power usage for displays in this series ranges from 40 W to a maximum of 1000 W.
Scoreboards in this series use red-orange LEDs for optimum outdoor visibility.
The outdoor LED displays are modular in construction, typically with a top and a bottom section, but
some are comprised of as many as four different sections. The units are shipped separately and joined
at installation. Unpowered sections, connected to the internal power and signal enclosure with
