Abstract
A flameless candle includes a shell that has a sidewall and a hollow interior region. The sidewall can be made of a waxen material. The sidewall has a thickness and opacity. The shell also has a hollow interior region within the sidewall. A lamp (for example, LED) may be housed within the hollow interior region. The flameless candle also includes an insert. The insert can be made of a waxen material that may have different properties from the material of the sidewall. The insert is positioned in a top area of the hollow interior region. The insert includes a shading wall that has a thickness and opacity. The thickness of the sidewall may be different than the thickness of the shading wall. As another option, the opacity of the sidewall may be different from the opacity of the shading wall.
