That takes time and skill, so you can expect to pay a premium price for the effect. Normally, it is anywhere between $25 â $50 if you buy individual spray tans, in a package of 5 or10 it will be less.
LEDs are âdirectionalâ light sources, which means they emit light in a specific direction, unlike incandescent and compact fluorescent bulbs, which emit light and heat in all directions. For this reason, LED lighting is able to use light and energy more efficiently in many applications.
Energy efficiency, sometimes called efficient energy use, is using less energy to provide the same level of performance, comfort, and convenience. For example, an energy efficient compact fluorescent light bulb (CFL) uses 85% less energy than a conventional incandescent bulb to produce the same amount of light.
