A lighting system comprising:

• a housing having a top side and a bottom side, the top side facing away from a space to be lit, and the bottom side facing the space to be lit;
• a lighting control region disposed on the bottom side of the housing that illuminates the space to be lit, the lighting control region having an elongate recess, the lighting control region also having a first control channel, a second control channel, and a third channel, each of the first and second control channels and the third channel extending length-wise along a direction of the lighting control region;
• a light-emitting module configured to be releasably coupled to the housing within the elongate recess such that the light-emitting module is electrically connected to the first control channel and emits blue light and such that the light-emitting module extends over each of the first control channel, the second control channel, and the third channel, wherein the light-emitting module includes a flexible tab to releasably couple the light-emitting module to the housing;
• and
• a switch assembly coupled to the housing and operable to selectively deliver power to the light-emitting module.
