winsaLED ST19 4W LED Bulbs 2700K 450lm – 40W Eq, E26, Non-Dimmable (12pk)

Immerse your space in a warm, inviting glow with the winsaLED ST19 LED bulbs. Delivering 2700K soft white light at about 450 lumens, these bulbs create a cozy atmosphere ideal for living rooms, bedrooms, and dining areas. The nostalgic teardrop glass and visible LED filaments bring a vintage Edison vibe to modern fixtures.

Designed for energy efficiency, each 4W filament bulb uses far less power than a traditional incandescent while offering a long lifespan—over 25,000 hours. The high color rendering index (CRI 90+) helps colors appear natural and true under artificial lighting, making everyday décor and textiles look more vibrant.

Key features pair with practical benefits. The clear glass and four filaments deliver a flicker-free, glare-free experience, supporting comfortable evenings and relaxed conversations around the home. A non-dimmable design keeps lighting levels consistent, so you can plan lighting scenes without unexpected changes in brightness.

What makes these bulbs a compelling choice

• Energy efficiency: 4W consumption delivers a similar brightness to a 40W incandescent, backed by a long 25,000+ hour lifespan.
• Warm, inviting ambience: 2700K soft white light with 450 lumens creates a cozy atmosphere in shared living spaces.
• Retro aesthetics meets modern color accuracy: Vintage ST19 teardrop shape with high CRI 90+ for true-to-life colors.

Ideal setups and use cases

• Living rooms, bedrooms, and dining areas where a warm, comfortable mood is desired.
• Ceiling fans, pendants, vanity lights, lamps, and accent fixtures that benefit from clear glass styling.
• Indoor spaces where color fidelity and a classic look enhance décor and textiles.

Installation and practical notes

Easy screw-in installation using a standard E26 medium base. Before purchasing, confirm that your fixture’s socket and size will accommodate the bulb’s dimensions. If a bulb doesn’t light, reseat it firmly in the socket and retry.

Important: these bulbs are not dimmable, so brightness cannot be adjusted. Plan lighting layers accordingly to maintain a consistent ambience throughout the room.
