Product Design Introduction
WEEFINE Smart Focus 2500 embodies a novel design concept rooted in
the essence of the WEEFINE brand. Crafted with an elegant black aluminum
alloy casing, which undergoes a rigorous process of hard oxidation, it
exudes a fashionable and cutting-edge appearance, boasting a remarkable
maximum brightness of 2500 lumens.
1. It incorporates the WEEFINE brand's innovative patented circular
battery indicator, which provides uniform light transmission and enhances
the product's stylish and aesthetic appeal.
