Spuldze LED E27 5.5 A40 4000K MAT 470Lm Ledvance

Efficient light emitter in the system, general-purpose LED bulb for standard E27 socket setups. Cold white color temperature suitable for workspaces and task-oriented illumination. Provides consistent light output with reduced power consumption compared to traditional incandescent bulbs. Consumes 5.5W of electrical load, outputs luminous flux rated at 470 lumens—adequate brightness for compact spaces or indirect lighting setups. Operates on A40 form factor dimensions, matte finish housing enhances light diffusion while minimizing glare. 270-degree beam angle covers wide spread without harsh focal points. Direct replacement unit fits most existing fixtures designed for E27 standards without additional modification or adapters. Technical notes: E27 base type. Rated lifetime up to ~15,000 hours typical use conditions. Color rendering index (CRI) ≥80 provides natural look to lit objects, not overly saturated or washed out under the bulb's emission spectrum. Power efficiency ~85 lm/W overall output-to-energy ratio confirmed operational performance limits consumer-grade spec expectations. 4000K color temperature cold neutral tone suited non-decorative aesthetic installs task zones precision-oriented utility indoor uses preferred areas workspace retrofits no heat buildup efficient running ambient normal ceiling desk positions flood limited overhead axial limits expand hallway cluster functions configuration designs restricted pivot sources minimal custom shifts rotate maximum heat dissipation maintained outer contour low thermal envelope simplicity upgrades tested module basis environmental-friendly iterations advantages. 4058075292246
