Magners Light has the same amount of alcohol as original Magners - 4.5 per cent abv - but just 28 calories per 10cl, compared to 37 calories in the original cider.
Brand manager Richard Barnes said: "With all the authentic endorsement of the Magners brand, the low-calorie option of Magners Light embodies the quality, craftsmanship and heritage of Magners Original Cider which has contributed to its growth in Great Britain.
"We know lifestyles continue to change, and as the light drinks market continues to grow internationally, consumers are ready for a great-tasting light drink alternative from a credible, quality brand - Magners Light matches that need perfectly."
The new variant comes in a 33cl long-neck bottle with a silver neck foil and silver front and back label to differentiate it from the original version.
