    Abstract: The present disclosure provides a covering for a light-source comprising a polyolefin composition comprising: (A) 50-80% by weight, of a propylene polymer comprising up to and including 40% by weight, based on the weight of (A), of units deriving from ethylene and/or at least one alpha-olefin of formula CH2=CHR1, where R1 is a linear or branched C2-C8 alkyl; (B) 15-35% by weight of an elastomeric component selected from the group consisting of: (B1) ethylene copolymers with at least one alpha-olefin of formula CH2=CHR2, where R2 is a linear or branched C1-C8 alkyl, (B2) saturated or unsaturated styrene or alpha-methylstyrene block copolymers, and (B3) combinations thereof; (C) 5-30% by weight of glass fibers, and (D) 0-5.0% by weight of a compatibilizer, wherein the amounts of (A), (B), (C) and (D) are based on the total weight of (A)+(B)+(C)+(D), the total weight being 100%.
