I can see it being useful for some things. However the light would not project very far. I also question the need for light for your peripheral vision. In the winter on weekend I live with a headlamp on, starting work before dawn, and no exterior lights. Then the sheds I work in are terribly lit (what genius thought three bulbs in a 50x100 shed was a good idea). When at customer's homes we are working in the basement looking in dark holes. My favorite light is a Coast HL27, however it is heavy and bulky. But it has a good spot light, and decent flood light. It is not the brightest at 330 lumens, but it places the light good enough that I suspect you would get more light directly in front of you were your working compared to the light bar. You can also increase and decrease brightness as well as changing the focus from spot to flood or some where in between.
It is my opinion that the lightbar would not direct the light were I needed it as it is wasting too many lumens on the side vs putting it directly in front of you. I wear glasses so I have to move my head to look were I want to see, so a beam that is not super wide is acceptable. Also there is no way to angle it down, so the light would be directed upwards due to the angle of most people foreheads. The lack of a spot function for me would be deal killer. But it might be good for other uses such as night exercise were the wrap around effect would make you more visible and the light output would be a secondary benefit.
