Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluation of various types of light exposure at various, targeted regions of the body while engaging in a different activities and settings.	After sensors are removed researchers will collect dosimetry data using a phone application using Near Field Communication (NFC) with a phone that is restricted to research use only in this study. Location, indoor/outdoor conditions and time that the devices are used will be recorded by the study team. Location, external environmental factors (weather, UV index) and activities will be recorded by the research administrators.	Time Frame: 1 year
