I am actually torn between two brands: Baja Designs and Diode Dynamics.
I know this makes it sound more like a fog-light shootout, but this is for an 18-20” upper grill light and a 30” lower grill light.
Diode Dynamics 18” light bar: upper grill
Stage Series 18 inch White Light Bar
Diode Dynamics 30” light bar: lower grill
Stage Series 30 inch White Light Bar

On paper, the Baja Designs claim WAY more light output with super high (lumens) numbers. However I haven’t heard a single bad thing about the Diode Dynamics light output - even though their published numbers are significantly lower than most of their competitors. The ONLY thing I don’t like about the DD lights is that that don’t seem to have a truth combo lense, but you have to put a flood lense on the entire 6” portion of the light…. If not, it’s all just one big spot beam.
As for the Baja Designs, if I go that route, IÂ’m looking at the ONX6+ lights. The are physically larger, but only slightly more expensive than the S8 bars - yet that have literally twice the output!!
What are your thoughts/recommendations?
The Baja lights are going to be brighter/throw further, most likely. For the 18 inch bar, it's only pulling 80 watts (less than 5 watts per chip, 18 chips). The OnX6 has nearly triple that power consumption in the 20 inch bar, at 18 watts each for 12 chips. Even though the DD bar will have a tighter focus (less wasted/spilled light) due to the TIR optics, the Baja bar will shine further just with brute power and fairly large reflector bowls. And some prefer the extra spill for periphery lighting.
There are only 3 optics for the DD bars: driving, flood, and fog/wide. They do not offer spot patterns, as the driving pattern is cast directly into the TIR optic. A driving pattern is similar to a spot pattern, except it has a slight horizontal spread to light up the full width of the road ahead. A clear lens is placed over a driving optic to leave the pattern unmodified, while the fog/wide optic modifies this horizontal spread further. The flood lens modifies and spreads the pattern vertically and horizontally. You can make your own combo by changing any of the 6 inch segments.
All of the chips used in the Diode light bars are the same 5700K flat white color, regardless if you choose white or amber/yellow. Because of this, the amber lenses have a lot of heavy color filtration in order to reduce any green/blue hues. This makes the amber lights much less efficient, losing about 40% of output from the clear lenses.
The pods are newer, and have a lot of improvements. Instead of two piece optics (TIR and lens modifiers), all of the optics are single castings. Choices are increased to spot, driving, fog, flood, and combo (half driving, half flood) and power levels are sport, pro, and max (SS3 only). The yellow lights have 4000K warm white chips, meaning that their lenses need a lot less color filtration and they only lose about 8% of the output compared to the clear lenses.
Baja has strong pod light offerings as well, but the Diode pods excel when extreme focus is needed (spot, driving, fog) due to the superior optics. As a reminder, the $90 sport spot SS3 (a 3 inch pod) shines further than the $1K Baja XL Laser (a 5 inch laser pod). And fog lights aren't even a contest: each level of the SS3 fog is an incredible upgrade, while the BD SAE squadrons are dimmer than factory halogen lamps.
I chose the DD 30" bar for my roof bar (seen here flanked by Baja S2 pros as ditch/dust lights) mostly because it was the one of the few that would fit in this 3 inch slot.
The biggest benefit over reflector-based bars though, was that it doesn't glare the shit out of my hood and blind me because of that tight pattern control. This control is a lot less important when mounted in your grill though obviously.
As for the color, I would consider the 5700K white to be fairly neutral, maybe a touch colder than the 5000K that Baja uses. The chips in the white DD pro driving lights are 6500K though, and you can definitely see the blue here compared to my roof bar.
That's why I switched to the 4000K driving lights (yellow lamps with clear lenses). Much better.
For grill bars: If you want raw power and don't mind spending the money, go with Baja. If you want tighter focus or street legal patterns, go with Diode. If you want to completely blow Baja out of the water with both power and focus, get an SS5 bar.
