Glad you mentioned that - I was hesitant for the same reason. Definitely a matter of personal preference, but for whatever reason I am not big into the LED bar "look". Even shied away from the ARB Intensity lights and their LED grid (that, and the $$$!). These seem okay, sort of subtle enough that I like the look.
There are a couple of options for the Rigid LEDs in the 2x2 layout that fit the Slee bracket. I went with the ones that are supposedly DOT/SAE approved, so they are bright but they don't throw a ton of light up past the headlights. (check out
@kevinfoutch posts around p. 178 - that was my inspiration to try this)
I tried to capture a comparison in the parking lot of a local burger joint. Somewhat difficult to compare, but the Rigid fogs definitely don't overpower the projection headlights (2013).

(taken with an iPhone so forgive the variation in exposure that makes it hard to compare. And yeah, fresh blacktop doesn't exactly reflect well either...
