Light Emitting Diodes (LEDs) have been around for years in red, yellow and green. Wider-angle LEDs have a lower brightness rating, but may put out just as much light. It's important to choose...
90-240 VAC LED Light Bulbs. Our LED Light bulbs are dual voltage; in many sizes: LED medium base, LED candelabra base, LED PAR20, LED PAR30, LED PAR38, LED RGB Color Changing, LED GU10.
An LED is a special semiconductor which emits light when current is passed through it. There are many different physical styles. The emitted color spectrum is usually very narrow.
LEDs emit light when an electric current passes through them. ... This tells you how much the beam of light spreads out. Standard LEDs have a viewing angle of 60° but others have a narrow beam of 30°
