I would definitely recommend getting their 27W side projecting pods (the ones you're looking at) over the 2x2 20W pods that I got. The projection area on mine is pretty narrow, whereas the side projecting floods would probably have much larger coverage. Brightness is decent - good enough to be helpful, but a light bar would probably be better if you want max brightness. Though, the side projecting pods have 30% more power so your experience might be different.
I installed the Cali Raised LED 27W side-projecting pods with the Cali Raised Low Profile Ditch Light brackets (I ordered the combo option of the wiring harness, pods, & switch). I haven’t noticed any noise and their brightness matches well with my Rigid grill-mounted light bar. I aimed them so the light cast just overlaps the outside beam of the headlights & light bar.
