Most antique schoolhouse fixtures use a standard Edison medium screw base (E26) and are compatible with 60W incandescent bulbs or LED equivalents; several listings explicitly note E26/medium-base and LED compatibility.
Most listings specify a 60-watt maximum per socket, though at least one pendant lists a 75-watt maximum — so both 60W and 75W limits appear in this category.
Shades are glass, most commonly white frosted or opal glass, which provides even diffusion and the classic bright, traditional schoolhouse appearance.
Most listings include the fixture and mounting hardware and state that light bulbs are not included. At least one listing specifically includes a single incandescent bulb with the hardware.
Lumen information is mostly not provided across listings; one listing specifies 3,375 lumens. Most listings instead provide maximum bulb wattage (commonly 60W) and note that bulbs are not included.
