The proper name for color temperature is The Correlated Color Temperature (CCT). The CCT is described in degrees Kelvin (starting at absolute zero). It is backwards in a way, because when a color of a light source has a high temperature associated with it, it is considered to be a cool color, and if it has a low temperature it is a warm color. Lighting sources with a CCT rating below 3200 K are usually considered "warm", while those with a CCT above 4000 K are usually considered "cool" in appearance. Using a light with a high Correlated Color Temperature will give a greater perception of brightness in the space than lower ones. When calculating a color temperature (CCT) we take the light we are looking at, and compare it to a Blackbody standard base line color model that has radiant power at all wavelengths of light, and where our color falls according to the base model will tell us what our color temperature is. Even at a given Correlated Color Temperature, color can vary. To avoid such variation, the EPA recommends you purchase bulbs from the same manufacturer at the same time. The color temperature rating is listed on the product packaging.
Instead of having the traditional small bulbs, battery operated fairy lights now come with LED lights. This type of light has a distinct glow that is crisper than the old incandescent light sources. The reason is that the color of LED lights comes from within whereas the bulb coating sets the color of most incandescent lights. It is no surprise to see indoor fairy lights that have LED lights, instead of the old bulbs. After all, LED lights are far more superior than traditional lighting source. Its advantages include lower energy consumption, more compact size, faster switching on display patterns and greater durability. Perhaps the only downside to LED lights is that they are relatively more expensive than traditional bulbs.
Safety is a critical issue. You do not want the wires exposed for children to trip over. You also do not want the wires to be prone to electrical problems, or even fire, so make sure you buy a fixture with safety properties. There are also particular flood lighting systems equipped with security and sensor features. if you are planning to buy these systems, you might as well consider getting two in one systems as they are more economical.
