Doch neben dieser ungemein hohen Effizienz sind weitere Vorteile äußerst begehrt: Mit LED Lampen wird das Spektrum an lichttechnischen Möglichkeiten drastisch erhöht. Das betrifft vor allem die Lichtfarbe, welche dem persönlichen Geschmack angepasst werden kann – eine Möglichkeit, die bei handelsüblichen Glühlampen nicht gegeben war. LED Lampen gibt es in drei Lichtfarben, wobei fließende Übergänge zwischen den Farben gewählt werden können. Die Lichtfarbe Warmweiß entspricht dem behaglichen, rötlichen Licht der Glühlampe. Sie eignet sich für Wohnzimmer oder andere Räume, in denen Gemütlichkeit vorherrscht. Die Lichtfarbe Universalweiß dagegen ist die ideale Wahl für Büroräumlichkeiten oder andere Arbeitsbereiche, in denen es darauf ankommt, sich nicht zu sehr zu entspannen, aber gleichzeitig das Gefühl von Sterilität und Nüchternheit ein wenig abzuschwächen. Das universalweiße Licht ist weißer als das der Glühlampe, was im direkten Vergleich umso mehr auffällt. Die dritte Lichtfarbe, Tageslicht, ist dagegen bläulicher als das universalweiße Licht. Im direkten Vergleich zur Lichtfarbe Warmweiß wirkt sie sehr kühl und nüchtern, was dieses Leuchtmittel für industrielle Einrichtungen oder aber auch OP-Bereiche in Krankenhäusern geeignet macht. Es ist ein Arbeitslicht für Bereiche, in denen es um akribische Genauigkeit geht, welche keine Gemütlichkeit zulässt. Die bläuliche Lichtfarbe wirkt sich gemäß einiger wissenschaftlicher Studien zudem auf den Schlaf-Wach-Rhythmus des Menschen aus. Das bläuliche Licht wirkt auf viele Menschen aufweckend, was einer der Gründe dafür ist, dass müde Kinder nach dem Zähneputzen und einer Konfrontation mit einer vielleicht zu bläulich gewählten Spiegelbeleuchtung aufgeweckter sind als zuvor. Den Namen Tageslicht trägt dieses Licht im Übrigen nicht willkürlich. Auch das echte Sonnenlicht ist in Wirklichkeit bläulich und nicht rötlich.

LED drivers are the essential components of LED lamps or luminaries. A good LED driver can guarantee a long life for an LED system and provide additional features such as dimming and control. The LED drivers can be put inside lamp or luminaire, which is called a built-in type, or be put outside, which is called an independent type. According to different applications, different types of LED drivers need to be applied, for example an outdoor driver for street light, an indoor point driver for a down light, and an indoor linear driver for a panel light.

The first LEDs were developed in the early 1960s, however, they were low-powered and only produced light in the low, red frequencies of the spectrum. The first high-brightness blue LED was demonstrated by Shuji Nakamura of Nichia Corporation in 1994. The existence of blue LEDs and high-efficiency LEDs led to the development of the first ‚white LED‘, which employed a phosphor coating to partially convert the emitted blue light to red and green frequencies creating a light that appears white. Isamu Akasaki, Hiroshi Amano and Nakamura were later awarded the 2014 Nobel prize in physics for the invention of the blue LED.

LED tube lights are designed to physically fit in fixtures intended for fluorescent tubes. Some LED tubular lamps are intended to be a drop-in replacement into existing fixtures if appropriate ballast is used. Others require rewiring of the fixtures to remove the ballast. An LED tube lamp generally uses many individual Surface-Mounted LEDs which are directional and require proper orientation during installation as opposed to Fluorescent tube lamps which emit light in all directions around the tube. Most LED tube lights available can be used in place of T8, T10, or T12 tube designations, T8 is D26mm, T10 is D30mm, in lengths of 590 mm (23 in), 1,200 mm (47 in) and 1,500 mm (59 in).

White LED lamps have achieved market dominance in applications where high efficiency is important at low power levels. Some of these applications include flashlights, solar-powered garden or walkway lights, and bicycle lights. Monochromatic (colored) LED lamps are now commercially used for traffic signal lamps, where the ability to emit bright monochromatic light is a desired feature, and in strings of holiday lights. LED automotive lamps are widely used for their long life and small size (allowing for multiple bulbs), improving road safety. LED lamps are also becoming popular in homes, especially for bathroom and medicine cabinet lighting.

White-light LED lamps have longer life expectancy and higher efficiency (more light for the same electricity) than most other lighting when used at the proper temperature. LED sources are compact, which gives flexibility in designing lighting fixtures and good control over the distribution of light with small reflectors or lenses. Because of the small size of LEDs, control of the spatial distribution of illumination is extremely flexible, and the light output and spatial distribution of an LED array can be controlled with no efficiency loss.

Some models of LED lamps are compatible with dimmers as used for incandescent lamps. LED lamps often have directional light characteristics. These lamps are more power-efficient than compact fluorescent lamps and offer lifespans of 30,000 or more hours, reduced if operated at a higher temperature than specified. Incandescent lamps have a typical life of 1,000 hours, and compact fluorescents about 8,000 hours. The lamps maintain output light intensity well over their lifetimes. Energy Star specifications require the lamps to typically drop less than 10% after 6,000 or more hours of operation, and in the worst case not more than 15%. LED lamps are available with a variety of color properties. The purchase price is higher than most other, but the higher efficiency may make total cost of ownership (purchase price plus cost of electricity and changing bulbs) lower.

Early suspicions were that the LED droop was caused by elevated temperatures. Scientists proved the opposite to be true that, although the life of the LED would be shortened, elevated temperatures actually improved the efficiency of the LED. The mechanism causing efficiency droop was identified in 2007 as Auger recombination, which was taken with mixed reaction. In 2013, a study conclusively identified Auger recombination as the cause of efficiency droop.

Some LED lamps are made to be a directly compatible drop-in replacement for incandescent or fluorescent lamps. An LED lamp packaging may show the lumen output, power consumption in watts, color temperature in kelvins or description (e.g. „warm white“), operating temperature range, and sometimes the equivalent wattage of an incandescent lamp of similar luminous output.

In January 2009, it was reported that researchers at Cambridge University had developed an LED lamp that costs £2 (about $3 U.S.), is 12 times as energy efficient as a tungsten lamp, and lasts for 100,000 hours. Honeywell Electrical Devices and Systems (ED&S) recommend worldwide usage of LED lighting as it is energy efficient and can help save the climate.

In 2009 the exceptionally large Christmas tree standing in front of the Turku Cathedral in Finland was hung with 710 LED lamps, each using 2 watts. It has been calculated that these LED lamps paid for themselves in three and a half years, even though the lights run for only 48 days per year.

The second basic method uses LEDs in conjunction with a phosphor to produce complementary colors from a single LED. The most common method is to combine a blue LED with a yellow phosphor, producing a narrow range of blue wavelengths and a broad band of „yellow“ wavelengths actually covering the spectrum from green to red. The CRI value can range from less than 70 to over 90, although a wide range of commercial LEDs of this type have a color rendering index around 82.

The colors available from both the basic types of white light LED is adjustable to a certain extent, with color temperatures in the range of 2,200 K (matching incandescent lamps) up to 7,000 K are widely available. Higher CRI values can be obtained using more than three LED colors to cover a greater range of wavelengths. Tunable lighting systems employ banks of colored LEDs that can be individually controlled, either using separate banks of each color, or multi-chip LEDs with the colors combined and controlled at the chip level.

LEDs using the color-mixing principle can emit a wide range of colors by changing the proportions of light generated in each primary color. This allows full color mixing in lamps with LEDs of different colors. Unlike other lighting technologies, LED emission tends to be directional (or at least lambertian), which can be either advantageous or disadvantageous, depending on requirements. For applications where non-directional light is required, either a diffuser is used, or multiple individual LED emitters are used to emit in different directions.
