Wide opal Sheffield-style glass shades like the 196OP were originally designed to maximize the amount of downcast light available from early carbon filament lightbulbs, which were considerably dimmer than today's bulbs. Reflected underneath an expanse of opal glass nearly a foot wide, the glow was considerably brighter and more focused.Even with better bulb technology today, broad, shallow shades are still used to focus light on tables and counters - the real working spaces of a household. Try the 196OP on our Powell, Vaughn, or Upshur for suitable task lighting. See more shades with a 2 1/4" fitter.
