This light is mostly polished brass and polished aluminum. Measuring from the ceiling mount to the wide lens end, this light measures about 32 inches tall. You can shorten the brass down rod to make the light as short as 24 inches tall, or make the down rod longer and have it hang to the desired length of your project. The wide end of this extra large cargo light is about 14 3/4 inches wide, and we have installed new glass. The ceiling mount plate is 5 1/2 inches in diameter with four mount holes.
