A lot of sea anemones have a facultative ectosymbiotic relationship with zooxanthellae and/or zoochlorella. Obviously these need light to carry out photosynthesis, and so in that sense yes, they do need light. However it is not really the anemone that needs the light, it's the algae and the anemone can survive without the algae, so in that sense no, they don't need light. It depends on what you meant by the question.
