Upgrade your LED flashlight, headlamp, or bike light with this precision-engineered Acrylic Convex Lens Reflector Lampshade Cover. Crafted from optical-grade PMMA, this lens effectively eliminates the common yellow halo effect and uneven spot patterns, delivering a soft, uniform beam with no stray light, black holes, or dark areas. Available in 23mm and 38mm diameters with smooth, bead, or strip surface finishes, it fits a variety of lighting applications—from MR16/PAR30/PAR38 cups to projection lamps, wall lights, underwater lights, garden landscape lights, and stage lights. Each lens is manufactured with a tight diameter tolerance of ±0.3mm for a secure fit. Choose from single or multi-pack options to meet your project needs.
