Ruby Lenses
Category: Gear
Price: 25 gp
Weight: 3 lb
Description: These red glass inserts let you reduce a lantern's brightness without limiting the area it illuminates. The red glow is easier on the eyes, and it doesn't attract as much attention as the bright light of an unfiltered flame. The light that passes through a ruby lens is dim, but its radius is unchanged.
