Buoyant sales of lighting and electrical fixtures boosted shares of Havells, founded by Vinod Gupta's late husband and run by youngest son Anil Rai Gupta, who is listed with her this year. Havells sold its 80% stake in troubled European light manufacturer Sylvania in December for $160 million to Shanghai Feilo Acoustics. Havells has recently started selling home-automation products and solar streetlights.
