The light main body 31 can be supported by the tripod stand 92 as shown in FIG. 13 by being screwed into the nut member 64 on the bottom surface of the light main body 31 removed from the 70.

And in the light 30 of the form 2, the lighting mode of the LED 34 and the notification control of the remaining capacity decrease of the battery 41 may be as follows.
First, here, each time the button unit 62 is pressed, the lighting mode of the LED 34 is switched in the order of “OFF”, “ON (High)”, and “ON (Low)”. Here, when the remaining capacity of the battery 41 decreases during lighting in the low mode with a small amount of light, only one LED 34 (here, blacked out in FIG. 14) is automatically switched from the low mode to the high mode with a large amount of light. The lighting is continued by switching, and the rest is turned off. Further, if the remaining capacity of the battery 41 decreases during lighting in the High mode, the lighting of only one LED 34 is continued in the High mode, and the rest is turned off. As a result, a decrease in remaining capacity can be notified.

One lamp that continues lighting when the remaining capacity is reduced is selected for the following reason.
First, the six lamps surrounded by the frame A shown in FIG. 14 have higher visibility than the 14 lamps positioned around the six lamps. That is, it is easy to see even when working at a location oblique to the front of the light, and it is possible to reliably notify the operator of a decrease in capacity. Further, since it is far from the reflector 36 that is at a high temperature, the heat dissipation efficiency is good and the remaining capacity can be used effectively. That is, since there is little loss due to heat, it can be lit longer and the time for the operator to replace the battery can be extended.
Therefore, of the 6 lamps in the frame A, 2 lamps (2 lamps surrounded by the frame B) located in the center of the irradiation surface are considered to have the highest effect. One is selected.
However, lighting is not limited to one lamp when the remaining capacity is reduced. For example, lighting of two lamps in frame B is continued together, or lighting of all six lamps in frame A is continued. It is possible to continue.

As described above, according to the remaining capacity notification control, when the battery voltage reaches a threshold value or less, at least one lamp is continuously turned on and the remaining lights are turned off, thereby effectively using the remaining capacity. Thus, it is possible to reliably notify the operator of a decrease in the remaining capacity.
In particular, by selecting the LED that continues to be lit from the one close to the center of the irradiation surface, high visibility can be obtained and the remaining capacity can be used more effectively.
