Professional designers know that half top hats can provide better performance than full top hats. That’s because when a full top hat is inserted into a lighting fixture, the bright source of the light is hidden, but the interior of the top hat is lit up brightly. By using a half top hat rotated with its full side toward the viewer, that bright interior disappears and the lighting fixture can no longer be seen.
Note: We do not recommend the use of 5” long accessories in 50° lens tubes. Loss of light will occur. We do not recommend the use of any accessory in 70° or 90° lens tubes. Extreme loss of light will occur.
