There are plenty of issues that need research for it to become a reliable, long-term solution for either lighting or displays. One of its disadvantages is its rather short lifespan. Blue OLED components only have the lifetime of 14 000 hours, which is about 8 years with regular use of the display. This is too little compared to current solutions available on the market (LED, LCD), and more expensive as well. Also, since blue components lose their lifespan faster than other components, their visibility is a difficulty. Blue light is more difficult to detect by the human eye, so they need to be generally more powerful. The problem has been solved so far with optimizing the colour ratio within a pixel, to balance out the differences in lifespan. Also blue light is set as more intensive, often resulting in an artificial-looking picture on the display. Further issues can be water resistance (as OLEDs are ruined by water instantly, so their outdoor performance hugely depends on the constructions IP rating); the high power consumption of white light displays; or screen burn-in, which can happen due to the differing lifespan of the colours.

This translates to getting the maximum amount of benefits for your dollars. The reason for this is that H.I.D. headlights work longer than halogen lights because they don't include filaments and halogen gases to emit light. Have you ever wondered why some of your household halogen lights literally burn out? It's the filament inside it. H.I.D. headlights, on the other hand, don't use filaments. They only use gases. When an electric current is placed through them, they give off a much more visible light than using filaments alone. And since there are no filaments, you don't have to worry about malfunctioned headlights when you're driving long distances.

Once in their places, you shouldn't be concerned that extremes of heat and cold will warp or break the material. They are made to withstand both heat and cold equally well.

No parts of cord-connected luminaires (fixtures), hanging luminaires (fixtures), lighting track, pendants, or ceiling-suspended (paddle) fans shall be located within a zone measured 900 mm (3 ft) horizontally and 2.5 m (8 ft) vertically from the top of the bathtub rim or shower stall threshold. This zone is all encompassing and includes the zone directly over the tub or shower stall."

Another advantage of low voltage outdoor lighting is that smaller and compact fixtures are flexible and can be activated by timers, motion detection or switches. This is an advantage as compared with high or regular voltage lighting fixtures that require conduits and labor to fix wiring. The size and design of low voltage outdoor lighting fixtures help add to the aesthetics of surrounding. The reason they can be safely hidden or placed in nooks and corners, waterfalls, bushes or exterior of buildings and residences. The drawback is that to highlight a particular area more fixtures are needed. Quality also matters in that if inexpensive crack and corrode due to extreme temperature or corrosion. The inconvenience ends here as low voltage outdoor lighting once installed requires minimum attention. Nevertheless a perfectionist or cleanliness freak would like to coat sockets with silicon - based lubricants once a year, clean accumulating debris in up-lifting fixtures and replace dead lamps to avoid unused voltage.

Ah, and let's not forget the vegetation and rest of decoration in the garden as well. Note that each of these 'items' will either absorb light or reflect it. Hence, you need to estimate the height of each of them, particularly when it comes to the foliage.
