Dimmable LED Light Bulbs, Daylight 5000K Large A21, 2 Pack | Dimmable Light Bulbs, Flicker Free, Super Bright, 250W Eqv, 4000LM, CRI 85, E26, 22-Year Energy Saving, Home Office Garage

BRIGHT & EFFICIENT: This upgraded version offers high efficiency. Compared to other light bulbs, this dimmable LED bulb with an E26 base delivers 4000 lumens while consuming only 27 watts, which is equivalent to a 250W incandescent bulb. Based on 3 hours of daily use, it can save up to 90% on electricity, with an estimated annual cost of 2.95.
DIMMABLE & FLICKER-FREE: Utilizing high light transmission optical lenses, up to 156 LED chips provide the daily illumination required for a healthy living or working environment. It features smooth dimming from 0% to 100% and is compatible with most TRIAC dimmers available on the market. For optimal dimming performance, please choose a suitable dimmer. It operates without flickering and without noise.
PATENTED CERAMIC TECHNOLOGY: The patented technology replaces the traditional MCPCB aluminum substrate with a non-conductive ceramic heat sink, where the LED chip is directly soldered. This effectively reduces the systematic thermal resistance between the LED PN junction and the heat sink surface, leading to quicker heat conduction and enhanced product reliability, resulting in greater light efficiency.
SAFE & RELIABLE: The body of this dimmable LED light bulb is constructed from a special ceramic material with a V0 flame retardant grade. The reinforced insulation structure removes the risk of electric shock, enhancing safety. The entire shell material achieves a WF2 anti-corrosion grade for improved reliability and durability. The hollow design assists with heat dissipation. For best performance, use this bright light bulb in a well-ventilated environment, away from sealed lampshades.
SELECTABLE COLOR TEMPERATURE: This dimmable LED light bulb provides two color temperature choices. Warm 3000K offers soft, warm, and comfortable light, ideal for homes and cozy spaces. Daylight 5000K delivers natural, near-sunlight illumination, suitable for living rooms, offices, schools, and other settings that require higher brightness and more realistic lighting
