not very long.. they are really crap...
i have one and its very dim...
Any Home Depot will accept burned out CFL bulbs for proper disposal and recycling. There's one in Tukwila, close to where you live.
In a lamp?
Yes, we could still live without the light bulb as there are alternative sources of light such as candles, oil lamps, and natural daylight. The light bulb has made life more convenient and efficient, but it is not a necessity for survival.
Albert Einstein's work on light and energy led to advancements in technology like LED light bulbs, which are more energy-efficient and longer-lasting than traditional incandescent bulbs. This has had a positive impact on reducing energy consumption and carbon emissions, shaping the way we live today by promoting sustainability.
That's hard to compare; improving energy efficiency often requires you to change a complete device for another device, for example, a light-bulb for a light-bulb that uses different technology. Whether the new device will live longer depends on the technology used.
The invention of the light bulb by Thomas Edison revolutionized technology by providing a reliable source of artificial light, enabling advancements in various fields such as manufacturing, transportation, communication, and healthcare. It also contributed to the expansion of infrastructure and the way people lived and worked, ultimately shaping the modern world we live in today.

The light bulb is important because it revolutionized how we illuminate our surroundings, making it possible to work, study, and live comfortably after dark. It also advanced various industries by enabling longer working hours and increasing productivity. Moreover, it has contributed to significant advancements in technology, particularly in the fields of electronics and energy efficiency.
Yes, if we look at the electrical energy used, illumination obtained and lifespan of LED lighting. LED light uses electrical energy 80% more efficient than Incandescent lighting, and 50% more efficient than fluorescent lamp. Led light uses electrical energy 80% more efficient than Incandescent lighting, and 50% more efficient than fluorescent lamp. Incandescent lifespan of about 2000 hours, 3500 hours halogen, fluorescent approximately 8000 hours, while the LED illumination can be expected to live up to 50000 hours and continue.
It depends on the region - how the energy is actually produced. If you live in an area where electricity is produced from wind energy, from a hydroelectric plant, or from solar energy, then the carbon dioxide produced to actually generate the electricity is zero. In other cases, it would also depend on the power consumption of the lightbulb - this can be anywhere between about 20 and 100 Watts.In any case, it is convenient to take energy-saving measures: in the case of lightbulbs, use light-efficient light-bulbs, and turn off lights you don't need.It depends on the region - how the energy is actually produced.

A light bulb can be dangerous if mishandled, broken, or overheated. Broken bulbs can expose live electrical components, while overheated bulbs can lead to fires. Additionally, improper disposal of light bulbs containing mercury can be hazardous to the environment.
The light bulb was invented by Thomas Edison in 1879. It revolutionized the way we live and work by providing a reliable source of artificial light. Edison's invention paved the way for further advancements in technology and changed the course of human history.
