Product review (4 stars): The airflow valve comes attached inside and I recommend you put 2 more screws to hold it in ...
OK product. I was expecting a more biffier metal but I guess it's ok since once installed no one will kick it. There is little discrepancy with the dimensions but it's acceptable. There are outputs on the top and on the back and you have to pop them out. Watch for the sharp edges. The airflow valve comes attached inside and I recommend you put 2 more screws to hold it in place. Less noise than I was expecting, it's a plus.
Uses regular incandescent bulbs but will accept fluorescents since it's the same socket.
