Black Oak 50 Inch S-Series LED Light Bar Review

Black Oak 50 Inch S-Series Single-Row LED Light Bar

When you want your off-road vehicle to look like dawn coming over the horizon, Black Oak’s 50-inch S-Series LED light bar is just the ticket for turning night into day. Equipped with 50 top-bin 5W OSRAM LEDs, this light bar delivers a night-ripping 27,500 raw lumens of clear, white brightness. If you think that is a bit much, drop back to Black Oak’s 3W LED version, which still puts out an impressive 15,550 raw lumens.

This light bar also offers three beam patterns.

  • Choose the Spot beam for deep penetration that you will never outrun at top speed. Hunters love it for seeking game up to a mile away.
  • The 50-inch S-Series Flood beam sets awash the entire scene from shoulder to shoulder.
  • The Combo beam pattern is a popular choice as it combines the Spot/Flood patterns, which makes it a light for all seasons and applications.

Whichever LED option or beam option you choose, rest assured that you can take this rugged light bar wherever the trail or road leads you. It is built from the highest quality materials and components. Black Oak’s lab torture tests prove it will withstand the harshest environmental conditions you may encounter.

They built this light bar to the maximum intrusion rating of IP69K and U.S. military standard MIL810-STD. To get there, this light has undergone hot water sprays up to 1450 PSI from every angle to ensure it is entirely waterproof.

What’s in the Box?

Every Black Oak S-Series light bar comes with all the hardware and wiring accessories for a complete installation right out of the box. All you need are a few hand and power tools and an hour or two of spare time to have your light mounted and switched on. If there are any issues, Black Oak customer service is ready to help you out.


Black Oak’s 50-inch S-Series light is an outstanding example of Black Oak’s commitment to using the highest quality designs, engineering and top-drawer components. You will not find any off-bin LEDs in their lights. Their quality LED drivers optimize LED efficiency and ensure maximum lifespan. Buy a knock-off light and within a few months to a year you will experience dimming, burn-outs and flickering due to their use of cheaper LEDs and low-quality circuitry.

Check out LED light bar reviews for any other brand to see the most common complaint is condensation inside the lens after a few weeks or months of use. Black Oak’s IP69K intrusion rating guarantees that will not happen to you. This light makes generous use of fasteners, one every two inches, and a custom rubber seal that never requires dismantling and re-sealing as is the case with so many other light bars.

The only valid gripe in a few reviews is that with a light this long, you sometimes need additional mounting options other than end brackets. It would be nice if Black Oak could start supplying custom mounting hardware to address that issue.


Black Oak LED’s S-Series 50 inch LED light bar delivers more long-lasting brightness and durability for your light bar dollar than any other light bar brand on the market. Compare their technical and quality specs head-to-head with any top-rated light bar maker and you will see why they are the ones to beat. This longest, single-row light bar in Black Oak’s arsenal will deliver the night-shattering illumination you need to conquer any trail, work application or nighttime recreational activity.
