The lamp assembly can include one or more lamps such as one or more light emitting diodes (LEDs). The diffuser globe is preferably a fumed blown glass diffuser globe having a concentrated region for refracting and diffusing light. The diffuser globe can include an internal diffuser for further refraction and control of the light. Embodiments also include a solar powered hook-shaped luminaire having a solar panel, a body member, and a diffuser globe. Embodiments further include a shatter resistant, portable, remote controllable, programmable, rechargeable, and floatable lighting device and/or globe luminaire, which can be automatically, manually, remotely, and/or locally controlled. ## Claims ### Claim 1 A lighting device, comprising: a tubular current-conductive housing; a lamp assembly coupled to the tubular current-conductive housing, the lamp assembly including at least one lamp that is electrically coupled to the tubular current-conductive housing; an insulator sleeve disposed around an end portion of the tubular current-conductive housing and around at least a portion of the lamp assembly; a diffuser globe compression fitted to the insulator sleeve through an opening thereof, the diffuser globe including a concentrated region that is structured to refract light outwardly from the diffuser globe and inwardly within the diffuser globe; a shatter resistant glow-in-the dark protective coating disposed on an outer surface of the diffuser globe; a first conductor coupled to a resistor, wherein the resistor is coupled to a positive terminal of the at least one lamp; and a second conductor coupled to a negative terminal of the at least one lamp. ### Claim 2 (depends on 1) The lighting device of claim 1, wherein at least one of an inner surface and an outer surface of the diffuser globe has deposited thereon silver particulates structured to reflect portions of the light outwardly from the diffuser globe and inwardly within the diffuser globe. ### Claim 3 (depends on 1) The lighting device of claim 1, wherein the concentrated region is nipple shaped. ### Claim 4 (depends on 1) The lighting device of claim 1, wherein: the at least one lamp includes one or more light emitting diodes (LEDs); and the lamp assembly includes a heat sink structured to dissipate heat away from the one or more LEDs. ### Claim 5 (depends on 1) The lighting device of claim 1, wherein the second conductor is coupled to the tubular current-conductive housing. ### Claim 6 (depends on 1) The lighting device of claim 1, further comprising an internal diffuser disposed within the diffuser globe and coupled to the lamp assembly using the insulator sleeve, wherein the internal diffuser is structured to redirect at least a portion of the light toward the concentrated region to increase the intensity of the light emitted through the concentrated region. ### Claim 7 A lighting device, comprising: a hook-shaped tubular conduit; a solar panel coupled to the hook end of the tubular conduit, wherein the solar panel is disposed at an acute angle θ relative to a normal; a body member having an opening therein, the tubular conduit extending through the opening and coupled to the body member; and a diffuser globe coupled to the shank end of the tubular conduit. ### Claim 8 (depends on 7) The lighting device of claim 7, further comprising: a battery pack configured to hold one or more rechargeable batteries, wherein the battery pack is disposed within the body member and electrically coupled to the solar panel for recharging; and one or more light emitting diodes (LEDs) coupled to the battery pack. ### Claim 9 (depends on 8) The lighting device of claim 8, further comprising: an actuator coupled to the battery pack and structured to electrically connect, when actuated, the one or more batteries to the one or more LEDs so that light is emitted from the diffuser globe. ### Claim 10 (depends on 7) The lighting device of claim 7, wherein the tubular conduit is coupled to the body member using one or more grommets. ### Claim 11 (depends on 7) The lighting device of claim 7, further comprising: a first insulator sleeve disposed around the hook end of the tubular conduit and coupled to the solar panel;
