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.
Compared to traditional incandescents, energy-efficient lightbulbs such as halogen incandescents, compact fluorescent lamps (CFLs), and light emitting diodes (LEDs) have the following advantages: 1  Typically use about 25%-80% less energy than traditional incandescents, saving you money.2  Can last 3-25 times longer.he table below compares a 60 watt (W) traditional incandescent with energy efficient bulbs that provide similar light levels.
