A flashlight including a light source, a power source, at least one push button electrically coupled to the light source and power source, and a rotatable switch assembly comprising a wheel, a cam fixed to the wheel, and a spring, wherein rotation of the wheel to different positions causes the cam to interact with the spring such that the at least one push button is selectively depressed, resulting in adjustment of the light source between different states of operation.

A ventilation housing of the present disclosure includes: a housing; and a ventilation assembly. The housing includes a tubular projection extending to project from an outer surface and internally having a first space communicating the inside and the outside of the housing. The ventilation assembly includes: an internal member being a tubular body having an opening at a first end portion and an opening at a second end portion; a gas-permeable membrane covering the opening at the first end portion of the internal member; and an external member being a tubular body having a bottom, the external member being joined to the internal member with the internal member inserted in the interior of the external member from the first end portion side. The ventilation assembly is fixed to the projection with the projection inserted in the opening at the second end portion of the internal member to make an inner peripheral surface of the internal member and an outer peripheral surface of the projection abut each other. The ventilation assembly has a second space serving as a ventilation path connecting the gas-permeable membrane and the outside of the ventilation assembly in the inside of the internal member, the inside of the external member, and/or an interspace between the internal member and the external member joined together. A height H1 of the internal member is 6 to 10 mm. A ratio of the height H1 of the internal member to a height H2 of the projection is 1.00 to 1.70. The ventilation housing of the present disclosure exhibits excellent performance in terms of moisture permeation between the inside and the outside of the housing and is capable of reducing dropping of the ventilation assembly from the projection of the housing.

A ventilation member of the present disclosure comprises: a support having a through hole that serves as an air passage between inside and outside of a housing upon attaching the support to an opening of the housing; and an air-permeable membrane disposed on the support and closing the through hole. The support comprises: a supporting portion in which the through hole is provided and at which the air-permeable membrane is disposed, and an insertion portion extending from the supporting portion and having an end with a hook, wherein the insertion portion bends in a direction closer to a central axis of the ventilation member while the hook is passing through the opening by being inserted into the opening, and fixes the ventilation member to the opening with the hook engaging the housing after passing through the opening. The ventilation member has a stopper portion with which bending of the insertion portion in the direction is restricted within an elastically deformable range of the insertion portion during the insertion into the opening. A ventilation member of the present disclosure can be reliably fixed to an opening of a housing with the insertion portion, even when the insertion portion is inserted into the opening at an angle.

Apparatus and methods for lighting. The apparatus may include an LED light source. The light source may be disposed in housing. The apparatus may include a circuit. The circuit may be configured to cause the LED light source to emit light at: a first intensity; and a second intensity that is different from the first intensity.
