Is the red headlight for photography a spotlight? Is he very different from the news light? thank you

There is a infrared lamp, which can reduce red eye at night under the external flash. There is also an indoor flasher. The lamp is energy-saving and effective. Only when this kind of lamp is used indoors, the lamp head should be turned on, otherwise there will be a red dot in the subject's eyes. I know that's all, and I don't know if it's what you want.
