The E3 Exeter has a cooling fan that is integral to the fixture. It is required for the fan to cool the LED sufficiently to meet the lamp life requirements we publish. On occasion we have had requests to lower the fan speed for these products since the cooling fan makes an audible noise in some applications. On higher ceilings with a more active noise environment they may not be noticed. If the customer requests that they reduce the fan speed due to noise concerns it has been determined that this is not acceptable and we cannot recommend making such changes. The fan speed that is used for the lumen output ordered must stay as it is manufactured.
