Overview
The flexible-loop filament range sits at 1800K — the warmest colour temperature in our catalogue. The looped filament creates a complex, animated glow that standard straight filaments cannot replicate. Available in gold (RG) and smoky (RS) glass: RG adds amber warmth; RS uses a grey-tinted glass for a sophisticated, moody character that suits high-end bars, boutique hotels, and theatrical settings. All models are CE/RoHS certified and fully dimmable.

Why Buyers Choose This Series
⭐ 1800K — the warmest CCT available, and the one high-end hospitality specifies
Interior designers for luxury hotels and restaurants increasingly specify 1800K for feature lighting. At this colour temperature, skin tones appear flattering and food looks appetising — effects that 2700K cannot match. HongYu is one of very few manufacturers that produces a full flexible-filament range at genuine 1800K (not 2000K mislabelled). The smoky (RS) finish — a grey-tinted glass — adds a layered sophistication that has made it a repeat-order choice for boutique hotel procurement teams.
