A23 bulbs are part of the most common bulb type, “A” bulbs. An A23 bulb has a diameter of 2.875 inches. The A23 bulb has one of the higher wattages compared to other A-shaped bulbs. This makes the A23 bulb the best option for commercial spaces that need A-shaped bulbs in recessed or downlight applications.
LED A23 bulbs help you save up to 85% percent of energy consumption when compared to incandescent bulbs. Many LED A23 bulbs feature dimming and work compatibly with dimmer switches for even more savings.
No, A19 and A23 bulbs are not interchangeable. These bulbs are not interchangeable because A23 bulbs have a larger diameter (2.875 inches) than A19 bulbs (2.375 inches). Due to their larger size, A23 bulbs will not fit in lampshades, frames, or other small fixtures. A19 bulbs, on the other hand, may fit where A23 bulbs fit depending on the fixture and lamp base required.
