This Diffuser is designed to work with the Aladdin A-Lite. Using the hinge, you can flip the diffuser up to get maximum brightness from the A-Lite or leave the diffuser down when you prefer a softer, more diffuse light. The diffuser can be completely removed from the A-Lite when it's not needed. It works on both newer A-Lites and on older models originally fitted with a screw-mounted diffuser.
