Rules that make the choice easier
Default to light in normal writing

Reserve lite for deliberate labels
Use lite when it is part of an official product name or when a clearly informal label intentionally signals a reduced version.
Do not invent lite compounds
Standard compounds such as lightweight and flashlight keep light. A playful spelling should not replace the conventional form in instructions or professional prose.
