converting existing lights to LED

Hello, I have a pool light and spa light that I would like to convert to LED color lights. What would be the easiest and cheapest way to convert these lights below?

Thank you for contacting Inyo. According to Pentair, The Pentair Intellibrite pool light will replace the Sta-Rite Sunbrite. The Pentair Intellibrite spa light will replace the SpaBrite/Aqualight. You’ll want to match the voltage and select the correct cord length.
