One use for LED lights is in a Chandelier. Tiny low voltage LEDs can be distributed around a chandelier far more easily than incandescent lights. The low voltage of the LEDs increases the safety and the low power use reduces the thickness of cable needed. The efficiency of the LEDs reduces the heat and so allows plastic to be used in place of glass. As the LEDs have a long life they can be built into the chandelier, rather than being user replaceable. Taking this to the extreme is the range of Schonbek LED Crystal Chandeliers
(the top of the range is the Da Vinci 72 LED DV3636A Single Tier Chandelier with Clear Spectra crystal).
Older places of worship, such as the Sultan Ahmed Mosque (the Blue Mosque) of Istanbul have been retrofitted with incandescent lighting. These could benefit from fitting small LEDs with less obtrusive wiring.
