Bright, Sturdy & Ultra-efficient

The Q-LED III underwater floodlight is powered by AC voltage. That means that the traditional halogen lights on your vehicle or other application can be “plug and play” replaced with Q-LED IIIs. It has an identical mounting pattern to the QL-3000 and Q-LED lights, the ROS industry standards that have illuminated the depths of the ocean for over three decades. The ultra-efficient Q-LED III’s light output exceeds that of a 500 watt halogen light, yet it draws significantly less power.

THe Q-LED III takes LED technology to the next level. The brightest ROS LED light, the intensity is impressive, allowing further and wider search effort visibility. Seeing is believing.

Regardless of duty cycle, the first recommended maintenance for the hassle-free Q-LED III is at the 5-year mark, when it is recommended that its three O-rings be replaced. After that, the light can go right back underwater.

The Q-LED III is certified submersible to 4,000 meters, and operates off of 120 or 220 volt AC power, as well as 160 or 320 VDC respectively. It has built-in thermal protection that de-powers the light before accidental use in air causes any damage; the light will automatically re-power once the temperature has returned to a normal level.

The innovative Q-LED III is the light that is bringing solid state lighting technology into the mainstream ROV world. Don’t get left in the dark -- replace all your old halogen lights with Q-LED IIIs today.

The Q-LED III underwater ROV floodlight has been deployed on numerous ROVs throughout the world and complements the INSPECTOR color camera from our array of underwater video cameras and the PT-10 positioner from our family of pan and tilt units.

NOTES - Q-LED III
(1)
Dimming can be achieved using AC phase control dimmers or adjusting the input voltage via a variable transformer. Phase control dimmers control the time that voltage is applied to the unit, which means the light will not react to the entire range of the dimmer like halogen lamps.
(2)
The Q-LED III is electronically protected from overheating via a thermal cut-off switch. The light will run approximately 5 minutes in air (at ambient temperature of 20°C (68°F)) before automatically powering down. There is no manual reset; the light will automatically re-illuminate once it cools to a safe operating temperature. The thermal protection is intended as a failsafe feature from unintentional damage due to extended use in air. Running the light out of water for any extended period will reduce the product lifespan.
(3)

Because the Q-LED III is not a purely resistive load, the electrical power ratings are VA (apparent power) rather than W.
