1 INTRODUCTION
This manual describes the installation and operation of the ROS Model Q-LED II
underwater light. This lamp utilizes a high output LED light array. This product line
represents the latest generation of LED array powered models. This version of the Q-
LED has the same profile than the previous model with the exception that the connector
is higher on the Q-LED II.
Like a conventional lamp, light dimming is achieved by decreasing or increasing the
input source voltage. Lights powered by AC voltage can be dimmed using an AC phase
control dimmer. If powered by DC voltage, Pulse Width Modulation (PWM) may be
used to dim the light.
The lamp is designed as a zero maintenance product. For problems or questions not
covered in this manual, please contact the factory or one of our authorized
representatives.
ROS, Incorporated, reserves the right to change or modify designs or specifications as
part of its continuing product improvement program.
