The 60- and 40-watt light bulbs are being discontinued because they fail to meet standards set forth in EISA (Energy Independence and Security Act of 2007). That legislation set a timetable that requires all screw-in electric light bulbs to use 25 percent less power by 2014 and 65 percent...
More and more homeowners are making the switch to LED light bulbs as prices continue to drop. These bulbs are extremely long-lasting and energy efficient, and they don’t suffer from some of the same durability problems of their filament predecessors, such as the tendency to blow out under c...

The LED Bulb In the last few years LED replacement bulbs have become much more common. Unlike ordinary incandescent bulbs, they don’t have a filament that will burn out, and they don’t get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material...
The construction of bulbs that create UV light is fairly simple, though there are several different ways to go about making “black lights”. A normal Fluorescent bulb creates light by channeling electricity through a conductive inert gas. They add a small amount of mercury inside the tube, or...

Firstly, top-rated LED lights can outperform a standard automobile light any day. They take less time to light up, and when working optimally, they can give you seven times the illumination you previously got. Only One-Third Of Electrical Power Is Needed LED lights are also popular due to...
Why are all compact fluorescent lamps more efficient than incandescent lamps? A 35 W and 100 W bulbs are joined in series and connected to mains. Which will glow brighter? What will happen when the bulbs are connected in parallel? What happens to the amount of power ...
