In regard to the replacement for 40W incandescent light bulbs, consumers can choose from not only 4.4W LED light bulbs but also 10W LED light bulb manufactured by Samsung. Samsung’s 10W LED light bulb with E27 socket can adequately replace 40W incandescent light bulbs, but falls short compared to the luminosity of 60W incandescent light bulbs.
This new product, named Samsung LED A19, can achieve a 75% energy conversion rate with a lifespan of 30 thousand hours, a beam angle of 180 degree, a 550lm luminous flux and a 3000K color temperature (warm white light).
In addition, Samsung also provides cold white light products, whose luminous flux reaches 690lm.
LEDinside points out that the box package of Samsung LED A19 light bulb is labeled with a mark of Light Facts, a program of the U.S. Department of Energy. Such a label can help consumers understand the traits of the product.
