This 40-pack module powered by just 1W is ideal for use as a depth sign (e.g. welcome sign) or logo at metros, airports, banks, shopping malls et al. This dust-tight, shock-resistant and water-resistant module utilizes the power of high output SMD2835 to ensure even and uniform single color of the light while leaving no dark spots anywhere. The module works best where depth signs of 8-15 cm depth are needed. One of the best things about this LED module is not only does it have special optics (uniquely designed lens) with 160 degree beam angle for wide area front or back lighting but LED encapsulation with 99.99% gold bonding wire along with a silver-coated pure copper bracket for better ductility and heat dissipation. This module helps you to make your sign/logo appear clearer, and easily visible while also lending color-contrast to the signage
