prvo treba da izracunas koliko ti treba da pokrijes prostr, drugo - one rade na tranformatore (treba ih sakriti, a i provesti one glavne zice do njih..a i malo je skuplje.
sretao sam se njima na puno mesta, ali uvek su nesto iza neke garnisle (osvetljavaju zavese ili zid), sakrivene da samo akcentiraju neki zid i slicno ili su sarene pa se menjaju boje (selo!)...stavljaju ih i kao glavna svetla, ali nisam toliko cesto video neku kucnu instalaciju da valja. U prodavnicama i izlozima, da...

evo malo uopsteno..

A LED light, or light-emitting diode, is considered to be the future connected with residential lighting. A great number of users have started to use LED light bulbs rather than the conventional incandescent ones or any other type of lighting options. Whilst incandescent bulbs take advantage of filament to produce light, LED bulbs depend on photons. These photons are produced by the motion of the electrons within semiconductor substance.

Many reasons exist for preferring LED lighting over other kinds of household lighting alternatives, specially the incandescent light bulbs. Considering power efficiency and life span, LED lights are far better as compared to incandescent bulbs.

Generally, LEDs consume one-fifth of the energy and operate 30 times longer when compared to the customary lighting bulbs. Whilst an incandescent bulb generate almost 98% of energy as heat, a LED bulb is able to burn pretty cool. At the same time, a LED light has a longer lifespan. Normally, LEDs can survive for 50,000 to 100,000 hours of use, but incandescent bulb is able to last for just 1,000 hours.

Since LEDs create so little amount of heat, they trim down the danger of fire or damage.

When compared to the gentle glass bulbs of incandescent lights, LED units are very powerful. Thus, LED units are hard to break even if they are dropped.

LEDs are considered to be extremely tolerant to cold, heat and shock. In contrast to other lighting solutions including the fluorescent bulbs, LEDs do not consist of a dangerous element known as mercury. They are offered in lots of colored lighting alternatives.

LEDs are equally eco-friendly as well as user-friendly. They don't radiate destructive rays like infrared lighting or ultraviolet radiation. They are ideal choice for spotlighting.

This sort of residential lighting can be quite expensive when compared with a number of other residential lighting choices, but it is definitely worth investing in it. For example, it will come at a price of roughly $40 if you are preparing to substitute your 25-watt incandescent bulb with a LED light. Yet, LED light is an ideal choice if you are in search of a power efficient residential lighting.
