Okay, I will do some measuring today. Any specific details on the brackets mounting without much modification?

In Dale we trust.
Hmm a 40 inch LED light bar for $450 WITH a 2 year no questions asked warranty? At that price, I don't see how you could go wrong. Dont get me wrong, I LOVE my rigid Duallys and will pay the extra $60 some dollars for them over competitors, but I do like saving nearly $900.

Easy enough to verify, though. Buy a light meter and a calibrator, and measure the illumination (in either US or metric units; footcandles or lux) at, say, 30 feet in a direct line from center, and then go out left and right in an arc, measuring at the same distance from the source. You might also be interested in luminance, though, which is the amount of light per unit area leaving a surface of interest - but to do that effectively you'd need a Lambertian reflector (think a square piece of teflon), and then measure in lumens (foot-lamberts) or in candelas (cd/m2).
Generally, for a good light you're interested in measuring reflectance, or the ratio of the amount of light (luminous flux) reflected by a surface (luminance) to the amount of light (luminous flux) striking the surface (illumination). But either or both of these vendors could pretty easily conduct tests such as these to help inform potential buyers of at least their light metrics, and in particular whether Rigid Industries' stated patented light system really is more effective.
Also of interest would be long-term heat dissipation and power consumption evaluations between the two, which would help get at the heat sink properties of the units.
I'm all for competition in the marketplace; let's see whether either or both of these outfits are interested in conducting side-by-side comparisons of their products to see which may or may not be worth what they're asking.
