ERG Room Recommendations

1. Light - red lighting for dark adapted testing. Longer wavelength reds are better.  Not necessary, but is nice for Dark adapting a patient.
2. Paint - black matte color for dark adaptation
3. General Room - no windows, under-the-door area covered so as to let no light through
4. Electrically - having the room on a separate circuit or using a surge protector is useful to reduce noise in results; this is not absolutely necessary 
5. Placement - away from large electrical appliances such as HVAC, refrigerators, elevators, etc. 

Room size is your discretion, but I would recommend it be comfortably sized for moving around with a cart that is about 2 feet long by 1.5 feet wide by 4.5 feet tall.
