AC COB LED bulb    
     Built with the Latest AC LED from Samsung!
Our LED bulb and LED downlight has been built with the latest LED technology from Samsung. It's the only bulb we sell that doesn't require a built in driver/transformer. Traditional LED's require a low voltage DC supply, therefore most LED bulbs have a built in driver/transformer to step down the voltage. Samsung's latest AC LED is different. It's designed to work straight from mains 230V AC or 110V AC without the need for a driver.

AC LED Lights C Driverless, Dimmable, Flicker-free, Longer Life!
LEDs (light emitting diode) are essentially diodes that use only electrical current flowing in one direction, commonly known as direct current. In conventional LED lights, a converter circuit, called a driver, is required to convert the high AC voltage to a lower DC voltage with a constant current for the LED light engine. However, the converter circuit not only increases costs but also shortens the lifespan of the LED lights.

However, AC (alternative current) LEDs can be connected directly to normal power supplies (usually 110V at 60Hz or 230V at 50Hz) and do not require a driver, like normal LEDs. The sinusoidal waveform circuit means that at each particular time half the LEDs are off while the other half is on, emitting light. This stage is reversed and repeated continually and, thus producing a constant stream of light.

Typically, small AC LED units are used as downlights and LED bulb, mainly because of their small size. These units have a wattage of 16W and a lumen output of 1250lm. Their correlated color temperature (CCT) is listed at 3000K and the viewing angle is 120 degrees. The unit has a diameter of 1.5 inches, making it an ideal fixture for tight spaces.
AC LED lights can become a compelling platform for retrofit lamps and other small scale lamps. Our patented technology is sure to become a serious contestant to the more traditional DC LED lights.
