Embodiments of the present disclosure provide systems, apparatuses and methods for regulation hormone production in mammals. Examples include but are not limited to by creating electro-magnetic wave emission pulse trains (photons) of individual color spectrums in sufficient intensity to drive hormone production in a mammal, using a characteristic frequency or pattern to minimize the required input power necessary to regulate hormone production, while also allowing for the monitoring of the power consumption and other variables of the system. By controlling the duty cycle, intensity, wavelength band and frequency of photon signals to a mammal, production of specific hormones can be regulated through the cycling between blue, green, yellow, near-red, far-red, infrared and ultra violet photon modulation.

The top bracket may include a top hook for receiving a top portion of a door, and the bottom bracket may include a bottom hook for receiving a bottom portion of the door.

A handheld light treatment device that aims to provide a wide variety of uses in personal care and household cleaning. The device contains a panel with light sources positioned behind a translucent or transparent head plate, to which is attachable an applicator disc and, optionally, applicator disc attachments with selected functionalities. The light panel shines light of different frequencies that may be useful for cleaning and sanitizing various surfaces. The applicator disc and applicator disc attachments have a substantially translucent or transparent base, allowing light from the light sources to shine through the head plate as well as applicator disc and applicator disc attachment, and the applicator disc to rotate while the light panel remains fixed. The applicator disc and applicator disc attachments may have bristles or other surface elements to facilitate cleaning or other uses, and the device may dispense an ingredient.

A light therapy device may comprise a housing comprising a front bezel and a back portion detachably coupled to the front bezel, a printed circuit board assembly coupled to the housing, and at least one LED electrically coupled to the printed circuit board assembly. The at least one LED may be arranged and configured to emit light through at least one aperture of the front bezel. In some embodiments, the at least one LED is arranged and configured to pulse at a predetermined frequency and a predetermined duty cycle.
