LED lights are the unrivalled choice of lighting when it comes to reliability in the marine environment. Compared to incandescent bulbs, they consumes less power and produce a more uniform light and at a color temperature that allows for greater penetration underwater.
We supply a range of ROV LED lights in 20 watt and 300 watt versions. Operational tests conducted have shown that the 20W unit provides roughly the same amount of light as a 150W incandescent light, while the 300W LEDs are roughly equivalent to 1500W of incandescent light respectively.
The 20W lights comes with a small power/dimming module to be installed in the ROV pod in place of the dimming unit currently installed.
The 300W models have an external power/dimming pod. The pod can be supplied with either 110 or 230VAC and the current dimming signal can be integrated into the pod to allow the LED lights to be dimmed using existing controls. Alternatively, we can supply a topside control unit which dims up to eight lights as required over a single RS485 circuit.
LED lights do not need to be changed on a regular basis as do incandescent bulbs as they are rated for a solid 50,000 hours and as there is no filament, there is nothing to break or burn out. In addition, our larger variants are microprocessor-controlled to prevent over heating. The light will automatically dim to prevent damage to the LED if left on for too long on deck.
The video below shows 40 watts of LED light followed by 300 watts of Incandescent light, then back to 40 watts of LED light. Note that there is less backscatter with the LED lights on.
