Size:Pack of 6 This dimmable filament 3.8-watt flame tip chandelier is a direct replacement for an incandescent 40W flame tip chandelier bulb. It uses less energy than an incandescent, which saves money on energy costs and has an average life of 15,000 hours. This bulb is used for decorative applications. Dimmable LED bulbs use ocular lenses to harness the output of high power Light Emitting Diodes (LEDs). The light output is comparable to incandescent and halogen products and can be used for both distance and close-range directional light. What makes LEDs special is that they achieve their brightness with up to 83% less energy than the bulbs they replace, and they last up to 15,000 hours. They are RoHS compliant and 100% mercury free. Additional benefits include no UV or infrared emissions, relatively cool running performance, ability to withstand vibration (no filament), no warm-up time or waiting to turn on and no detrimental effects from rapid cycling on and off.
