Do all wall packs come with a photocell sensor, and if not, can one be installed?
Not all wall packs come with a photocell sensor, but more often than not, one can be installed. Depending on which wall pack you're using, some photocell sensors may not be available. For example, you are highly likely to find a Semi Cut Off LED Wall Pack with a sensor, but not as likely to find a Bulkhead Wall Light with one. Most outdoor lights, such as semi and full cut off wall packs, that act as security lights have the capability to have a sensor. Make sure when choosing your wall light to read if it is photocell compatible, has the photocell sold separately, or comes with the photocell sensor.
