A housing has a narrow beam lamp and the wide beam lamp with a corresponding lens system to form a light beam with the desired divergence. A number of power control configurations are contemplated, including separate on/off switches, multi-position switches, luminosity level switches with a master on/off switch, and a single switch for each lamp that cycles through several luminosity levels. Power is supplied by batteries. The band includes a bracket attached to the housing and a strap that permanently or removably attaches to the bracket, the combination of which encircles the hand. The light includes mechanisms for adjusting the housing relative to the band. ## Claims ### Claim 1 A hand-mounted light comprising: (a) a housing having a front, a back, a top, a bottom, an inside, and an outside; (b) a pair of lamps emitting light beams from the front, each lamp having a lens system for setting the divergence of the corresponding beam; (c) a band attached to the inside and adapted to encircle a user's hand, the band including a bracket attached to the inside and a strap attached to the bracket; (d) a power source for powering the lamps; and (e) a power control for controlling the luminosity of the lamps. ### Claim 2 (depends on 1) The light of claim 1 wherein one lamp has a wide beam, and the other lamp has a narrow beam. ### Claim 3 (depends on 1) The light of claim 1 wherein the divergence of each beam is adjustable. ### Claim 4 (depends on 1) The light of claim 1 wherein the power source includes replaceable batteries and wherein the housing has a hatch for installing and removing the batteries. ### Claim 5 (depends on 1) The light of claim 1 wherein the power source includes rechargeable batteries. ### Claim 6 (depends on 1) The light of claim 1 wherein the power control includes power switches that are duplicated on the top and the bottom. ### Claim 7 (depends on 1) The light of claim 1 wherein the power control includes a separate power switch for each lamp. ### Claim 8 (depends on 7) The light of claim 7 wherein each power switch provides an off position and at least two luminosity levels. ### Claim 9 (depends on 1) The light of claim 1 wherein the power control includes a luminosity level switch for each lamp and a master switch for applying power to both lamps. ### Claim 10 (depends on 1) The light of claim 1 wherein the housing is adjustable relative to the band in at least one of roll, pitch, and yaw. ### Claim 11 (depends on 1) The light of claim 1 wherein the housing is adjustable relative to the band in roll, pitch, and yaw. ### Claim 12 (depends on 11) The light of claim 11 wherein the bracket is attached to the housing via a ball joint that permits motion in roll, pitch, and yaw. ### Claim 13 (depends on 1) The light of claim 1 wherein the strap is elastic. ### Claim 14 (depends on 1) The light of claim 1 wherein the strap is removable. ### Claim 15 A hand-mounted light comprising: (a) a housing having a front, a back, a top, a bottom, an inside, and an outside; (b) a wide beam lamp emitting a wide light beam from the front, a narrow beam lamp emitting a narrow light beam from the front; (c) a band attached to the inside and adapted to encircle a user's hand, the band including a bracket attached to the inside and a strap removably attached to the bracket; (d) replaceable batteries for powering the lamps, the housing having a hatch for installing and removing the batteries; and (e) a power control for controlling the luminosity of the lamps; (f) the housing being adjustable relative to the band in at least one of roll, pitch, and yaw. ### Claim 16 (depends on 15) The light of claim 15 wherein divergence of the wide beam lamp and divergence of the narrow beam lamp are adjustable. ### Claim 17 (depends on 15) The light of claim 15 wherein the power control includes power switches that are duplicated on the top and the bottom. ### Claim 18 (depends on 15) The light of claim 15 wherein the power control includes a separate power switch, and each power switch provides an off position and at least two luminosity levels. ### Claim 19 (depends on 15) The light of claim 15 wherein the power control includes a luminosity level switch for each lamp and a master switch for applying power to both lamps. ### Claim 20 (depends on 15) The light of claim 15 wherein the housing is adjustable relative to the band in roll, pitch, and yaw. ### Claim 21 (depends on 20) The light of claim 20 wherein the bracket is attached to the housing via a ball joint that permits motion in roll, pitch, and yaw. ### Claim 22 (depends on 15) The light of claim 15 wherein the strap is elastic.
