SWT deep-sea high-brightness LED light 300W, model: SWT-HSH-6300, adopts high voltage and wide range power supply design, mainly considering that ROV system underwater power supply is easier to obtain high voltage after rectification by transformer. Currently, the general voltage is around 120VDC. This LED light is designed for a wide range of input from 75 to 200VDC, which is more adaptable to the power supply. It is mainly used for large-range underwater lighting with a long exploration distance, providing a bright lighting environment for underwater HD video shooting and improving the success rate and quality of underwater HD video recording. It can be applied to various high-power underwater operating platforms.
