I assume you mean the energy they use. It really depends on the type of lamps. Often, electrical energy is used. A candle, as well as a lamp with a wick, uses the chemical energy in whatever fuel it uses (for example, the wax, in the case of a candle).
If you mean electric lamps; then these lamps use electric energy and convert it to light energy.
Energy saving bulbs (typically LEDs) provide higher lumens per watt compared to filament lamps.
LED lamps
There are two different technologies, fluorescent, and LEDs. Fluorescent light bulbs are more common; LEDs are still too expensive for mainstream use. +++ LED lamps' prices are now very competitive, certainly where I live, and make up for the unit price difference in reduced electricity consumption for a given light output. I have a mixture of incandescent, CF and LED lamps in my home, and slowly going over to LED as the existing lamps expire.
The Seven Lamps of Architecture was created in 1849.
The meaning of fine art lamps are wall, ceiling or table lamps that are highly decorative and artistic. One can find many for sale on websites such as Lighting Direct.
Many lamps use electrical energy, but some lamps use chemical energy, for example a kerosene lamp or a candle.
Energy efficient table lamps are available in many online shops such as LampPlus and YLighting. Lamps can even be made energy efficient by changing the light bulbs to fluorescent spiral bulbs.
i Brandon invented energy
Electrical energy is transformed into electromagnetic energy.

It is not the decision between lamps and ceiling lights that determine energy efficiency, but it is the bulb that matters. Try to use eco-safe lightbulbs to save energy.
Different light bulbs, lamps, flashlights, LEDs.
Energy saving lamps can be purchased at any store like Home Depot, Lowe's, Amazon, Walmart or Target. Sears even sells them. There are many places one can look into purchasing such lamps.

Neodymium is used in color televisions. It is a rare chemical that can be found in televisions as well as energy saving lamps and fluorescent lamps.
In traditional incandescent bulbs, tungsten is used as filament which draws heavy energy to illuminate, while in modern energy saving lamps we use CFL or LED which draw little amount of energy for the same luminance, CLFs are associated with a compact electronic ballast in the base of the lamp.
NO. Two 60W lamps will use 120W - which is more than 100W !!
