Black Oak 30 Inch D-Series Dual-Row LED Light Bar

Black Oak’s 30 inch LED light bar is the big brother to their popular 20-inch dual-row light bar in the middle of the D-Series product line. As such, it delivers a truly remarkable combination of versatility, power, durability and reliability at an industry-leading price point. You could spend hundreds more chasing better-known light bar brands and still fall short of the performance this light bar offers.

At this level, the top feature buyers look for is brightness. Black Oak hears you loud and clear, which is why they equip this formidable light bar with 60 top-bin OSRAM LEDs in two rows. While one top name in the LED light bar market sells the same size light bar for about 400 dollars more than this model, that light delivers just 40 percent the amount of illumination compared to Black Oak’s 30-inch light bar with 5W LEDs. Even their 3W LED option delivers 35 percent more light than that other brand.

So, did Black Oak skimp elsewhere to provide such outstanding value? They did not. In fact, their optics, lens, housing and circuitry meets or exceeds that of their top competitors handily.

The one-piece, rugged aluminum housing has been torture-tested by driving a truck over it. The shatterproof polycarbonate lens, custom seal and assembly has been subjected to 1400 PSI of hot water streams from every angle to earn it an international standards IP69K intrusion rating, which is the highest obtainable.

To get the highest performance and longest life from any LED, you need tight current and heat control from durable, high-quality LED driver circuitry. That is how Black Oak achieves over 95 percent light output efficiency and keeps their LEDs shining bright throughout their 50,000-hour lifespan.

If you are still not convinced that this is the best dual-row 30-inch LED light bar your lighting dollar can buy, consider that it is also backed by a 30-day, no questions asked, full money-back guarantee and a lifetime defect warranty. Not many LED light bar makers can match that level of product confidence.

When your Black Oak LED light bar arrives and you lift it from the box, you will feel why this is the best use of your vehicle lighting budget. Be sure to check out the curved model of this D-Series light bar too.

What’s in the Box?

The D-Series 30-inch LED light bar comes with all the mounting and wiring parts you need for a clean installation. In the box are instructions, mounting brackets, hardware and an entire IP69K-rated wiring harness including a Deutsch connector, dash switch, fuse and power relay.


The first thing noted in most buyer reviews is just how damn bright this light bar is. It wins out handily in side-by-side comparison tests with other big names in the LED light bar industry and easily outshines those cheap import lights.

Buyers love how rugged these lights are built too and the ease with which they install. They often remark on how sturdy the end brackets are and how easy the height of the beam adjusts without tools. This is a great feature when using this light bar for both trail driving and campsite illumination.

Due to the length, however, a few owners wish Black Oak supplied a couple more mounting options, such as channel mounts, studs or accessories to add it to a light bar pipe. In the end, however, that is a minor point compared to how much illumination and reliability their lighting dollar delivered.


In the 30 inch LED light bar class, Black Oak’s D-Series 300W light bar considerably outshines the competition in all dimensions: performance, durability and price. Many buyers wish they could give this light bar a rating of ten out of five! Black Oak LED backs up all their products with an industry-leading guarantee and warranty as well.

If you are looking to move up to a light bar that brings extreme daylight to the darkest night and is likely to outlast your vehicle, the D-Series 30-incher fits the bill without busting your budget.
