Good to meet you the other day.
The 30" bar came up a treat. Looks as though it doesn't obstruct your field of view which is a bonus. I bet there will a few more night drives coming up!

threedogs: The beam pattern on our single row lightbars is approximately 25 degree. It all depends on whether or not the light uses a reflector or refractor and also the depth the led is mounted at.
Our single row LED light bars use a 5w cree LED as apposed to the majority of dual rows which use 3w LED's so the current consumption is not quite half and the light output is not half either.
However, there are other manufactures out there still using 3w LED's in there single row lightbars and you are correct in saying the current consumption and light output would be very close to half of a dual row.

Cheers,
Paul
