Novel tools and techniques are provided for illuminating a portable space, which, in some cases, is based on passive infrared (“PIR”) detection. In some embodiments, a first device might detect presence of at least a portion of a user's body (e.g., a hand or face of the user, etc.). Based at least in part on detection of the presence of the at least a portion of the user's body, a second device might illuminate an interior space of a bag or other portable enclosure. In some cases, the first and second devices might be the same device, while, in other cases, the first and second devices might be separate yet communicatively coupled to each other (such as via wireless or wired connection). In some embodiments, the first device might include a passive infrared sensor or the like, while the second device might include light emitting diodes or the like.
