The phrase "are illuminated using a" is correct and usable in written English.
It can be used when describing a method or process by which something is lit or made visible, typically in a technical or artistic context.
Example: "The artworks in the gallery are illuminated using a combination of natural and artificial light to enhance their colors."
Alternatives: "are lit with a" or "are brightened by a".
