FR-GU10-4W-040DTW – GU10 Lights 4W 400 lm (DTW – Dim-to-Warm)

The FR-GU10-4W-040DTW is a premium gu10 led light bulb featuring advanced Dim-to-Warm (DTW) technology for natural, halogen-like ambience control. At full brightness, the lamp emits a clean, neutral white tone, while dimming gradually shifts the CCT toward a warmer, more intimate glow. This smooth transition enhances comfort in hospitality, residential, and decorative settings.

With a spotlight-style T35 × 46 mm form factor, the lamp delivers 400 lumens at just 4W, supported by a ceramic heat sink for long-term durability. Its beam angle options (24° / 36° / 60°) allow precise control of contrast and coverage. CRI levels up to Ra95 ensure excellent color fidelity, making the lamp suitable for premium environments where visual quality is essential.

Powered by a flicker-free driver, the FR-GU10-4W-040DTW offers stable, smooth dimming through leading-edge and trailing-edge dimmers. The DTW curve is tuned to mimic the warm, cozy falloff of traditional halogen sources—ideal for spaces focused on comfort and mood. As part of our high-performance gu10 led bulbs family, this model supports global voltage systems (110–240VAC) and ensures a long 25,000-hour lifespan.
