Thomas Edison's 140-year-old tech gives me some worries. Glowing filaments do not last very long any more. Yeah, it is approx 800 hours max. Incandescent light bulbs have a shine that is pretty nice. They bring a warm glow to many eyes.
However, over 90% of the electricity is wasted energy. This is why people are switching to CFL, but those contain mercury. Folks, mercury is a nerve poison. Yeah, it is very dangerous to use.
LED light bulbs are the best, but they are max expensive. $50 per bulb is common. People are trying to save money. Like we are now in a recession.
