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.
There is some confusion about this because compact fluorescent light bulbs (or CFLs) have typically been referred to as 'low energy light bulbs' by retailers. However, the reality is that there are a number of different kinds of low energy light bulbs available, including CFL and LED light bulbs. Just to make things more confusing, some rather inefficient lighting products, such as traditional incandescent and halogen bulbs, come in 'low energy' versions.
