RAB A19 4.5/9/14.5W 40/60/100W Equivalent 520/950/1600Lm E26 80 CRI 5000K (A19-4.5/9/14.5-E26-850-3WAY)

A direct LED replacement for a traditional three-way incandescent — the kind found in table lamps, floor lamps, and reading lights where a single switch toggles between low, medium, and high output. The A19-4.5/9/14.5-E26-850-3WAY pairs with a standard 3-way socket to deliver three distinct light levels at three matching wattages.

At 5000K (Daylight) and 80 CRI, the bulb covers everything from soft ambient light at the low setting to full task-level brightness at the top. The frosted lens diffuses light evenly, and the plastic construction lowers breakage risk versus glass three-ways.
