Optics make a huge difference and really separate bd from rigid and Chinese lights. My buddies all have rigid and I have rigid on the rzr and they were alright but after getting a couple bd xl80s and doing some research there is no comparison. The color is much more natural and their optics are in a different league. Definitely give bd a shot. Their high speed spots and racers offer a lot of distance.
Totally agree, Rigid is a quality light but the E-Series or the D2 does not compare to a BD Onx bar, XL80's, Squadrons for distance in my experience.
I would put the BD stuff up against a 8" HID or halogen for distance, they are unreal. I'll be driving through a steep pass in the Rocky's when the mountain in front of you looks a half mile tall, and no ******** the BD Onx 40" was lighting halfway up the ******* mountain when the distance is right. I'm no BD cheerleader but I can't deny how great the long distance throw is on them.
Silver, if I were you I would give an Onx bar or some XL80's/Squadrons a try for distance, you will be blown away. Throw a couple yellow lenses on some for fog, because the standard light will blind you in snow/fog/dust. I'm thinking about a Rogue bumper with the BD Onx bar or maybe the NFAB lightbar mount and throwing eight XL80's on that bitch.
NFAB BAR
Here's my old 38" Onx setup, lights worked awesome (for a while), and then the second I crammed in a 40" Onx, which was even brighter (for a while).
