You save hundreds of dollars, while enjoying the brightest, most rugged and long-lasting light bars anywhere.

Why bust your vehicle lighting budget on over-priced light bars that perform no better than those from Black Oak or waste money on cheap, dim imported bars with weak illumination and fogged lenses that start burning out almost as soon as you install them?

Black Oak sells light bars in almost every length, but their 40-inch D-Series curved model is one of their most popular sellers. It puts out up to 500W and 44,000 raw lumens of light that you never outrun even at highway speeds. The curved shape provides additional lighting to the sides while adding a big dash of style to your 4×4, truck, car or boat.

Black Oak LED 40 Inch Double Row Curved Review

Just like its “straight” brother, this curved dual-row light bar from Black Oak sports all the same specs with regard to brightness, waterproof rating, build quality and guarantees. It just adds a gentle curve to the length of the housing, which provides two benefits.

  • First, it often makes a better match to modern curved vehicle styling that even makes it look like OEM equipment.
  • Secondly, it delivers a wider beam regardless of whether you chose a flood, spot or combo beam.

The most popular configuration that takes full advantage of that extra curve is the combo beam.

As with all Black Oak light bars, we are overwhelmed with how over-built this light bar is. The dense, durable housing could be used for a baseball bat with no ill effects. The integrated heat sink with extra milled grooves keeps this light running cool and bright. Heat dissipation is key to getting LEDs to reach their expected 50,000-hour lifespan.

Like Black Oak’s other longer light bars, this one might benefit from a mounting channel to allow for additional mount points or special installations, but the included brackets are obviously strong enough to keep it in place even on the roughest trails.

verdictOur Verdict

If you cannot bring yourself to buy one of those cheaply made import light bars and cannot afford the premium prices the big-name makers charge, then Black Oak is the place for you. No other maker exceeds their build quality and brightness and certainly cannot beat their amazing prices.

Their curved 40 inch LED light bar is just one example of many in their full catalog. Be the first on your block to take advantage of their innovative products and prices.

This exceptional curved light bar from Black Oak easily achieves our best 5-star rating.
