Value: EL is the cheapest upfront. LEDs Price tag additional originally but lower your expenses over time. Fiber optics tend to be the priciest as a result of set up.
but LED assemblies with conformal-coated PCBs reach IP67 most reliably; EL panels involve thorough edge sealing in the phosphor movie to stop humidity ingress. IP sealing is achievable with all 3 technologies,
LEDs are evolving too—mini-LEDs pack much more electrical power into more compact spaces, and RGB selections Enable you to Enjoy with shades like under no circumstances in advance of. Fiber optics are finding smarter, integrating with devices for dynamic lights control.
