even if it is not is a Cree Cree LED COB built in very good quality. Although the lamp does not reach the 300 lumens, but measured between 240-260lm what the size, very reasonable price is still very good. Previously, I've relied on a well-known and very expensive brand, but this little flashlight is much more effective in the light output and the battery lasts longer. After reading many negative reviews here, I was a bit skeptical, but my work lamps properly (5 * 2 = 10 ordered).
