The bars do have TIR optics. However, the design is not as optimized. They have two piece optics instead of one. The TIR block with a driving optic is the first piece, and then the outer lenses are plain (unmodified driving optic), fog/wide (further horizontal spread) and flood (vertical and horizontal spread).

Also, they only come in one color (5700K), and the yellow lights have much darker amber lenses in order to filter out the shorter wavelength light. They lose something like 40% efficiency through these darker lenses, whereas the pods start with 4000K emitters and lighter yellow filters. They only sacrifice like 8% output from the white lights. And the one-piece optics come in spot, driving, flood, fog, and combo.

The bars were their first off-road product and as such, used off-the-shelf parts like generic extrusion for the heatsink, end caps, brackets, etc. The pods are a scratch-built product.

Myself and others have asked if and when they plan on updating the bars to incorporate all of the improvements that the pods have, but I only found one response on social media saying "they're on the drawing board". However, I don't think they're much past the brainstorming phase. They also will probably keep it under wraps until it's ready to reveal, as to not slow down sales on the current design.
