Overview
This is one of the most complete ETL-listed LED filament Dim-to-Warm catalogues available from a single OEM manufacturer — covering both standard shapes (A15, A19, G-series, B-series) and non-standard shapes including the T10-225 and T10-300 long tubular models. All models are available in both clear and porcelain white glass, ETL + FCC listed for 120V, with Ra 90 and Ra 95 options. The T10-225-E26-4W-DTW-W and T10-300-E26-6W-DTW-W are particularly valued by premium fixture companies: achieving a fully shadow-free, uniform glow across a 225mm or 300mm tube length in dim-to-warm mode is a technical challenge that most manufacturers cannot solve — HongYu's filament layout design makes it possible.

Why Buyers Choose This Series
⭐ The only ETL-listed DTW range with shadow-free T10 tubular models
Most 'dim-to-warm' bulbs on the market shift from 2700K down to 2200K–2400K, and most DTW catalogues cover only globe and standard shapes. HongYu's range does both things differently: CCT shifts to genuine 1800K at minimum dim (not 2200K), and the catalogue includes T10 tubular models at 225mm and 300mm length with uniform, shadow-free illumination across the full tube. The long T10-DTW models are deeply sought by premium US fixture brands who build elongated pendant and sconce designs — and there is no other ETL-listed source for them. CCT shift curves (measured at five dim levels) are included with every order for QC documentation.
