R4

8,592 crystal clear optically focused lumens will get you from A to Zimbabwe.  With eight top-binned CREE LED's, a pair of R4's generates more than 8,000 lumens. 

Like their big brother the R7, the extra distance and spread of the crystal clear 5000K daylight produced enables you to better see and be seen.  Trailside animals, pedestrians, and other hazards are more quickly perceived and reacted to.  Don't just survive a ride at dusk, enjoy the scenery along the way. 

The key difference between the R4 and R7 are output and size.  Both utilize machined optics to provide both a flood and spot beam pattern.  If riding a larger adventure bike (GSA, SAR, Multistrada), the ideal setup is to install a set of R4 and R7 lights.  With the R4's used as a DRL (daytime running light), and the R7 wired into your stock high beam switch, you will enjoy being seen by others during the day and have all the firepower in the world for night missions across the desert.  

Sold as both pairs and single units.  Pairs of lights arrive in a special RUBY branded box, single light orders are individually wrapped without the RUBY box.

A single R4 is rated at 4,296 lumens, 8,592 lumens as a pair.  

SPECIFICATIONS, per single light:

-290 grams

-33 watts, 2.4 amps (@ 13.4v)

-4,296 lumens

Note: this light has been renamed to R4, previously known as the R8.

Very nice lights

Tried them out for the first time on a trip to Death Valley and it was awesome.
They are very bright. We got caught out at night due to one of the bikes and I was leading the way so others could see. Awesome! Lights.

Too soon to say for sure, as my trip to Baja is 3 weeks away. But, what I can say is I’ve ridden around the neighborhood at night, and I know without a doubt that they’re going be fantastic. I also have R7’s on a GS. They light up the world.

Back to Baja: On every trip I go on there’s some delay due to detours, change of plans, or unexpected events. These occurrences often result in being in the remote bush in the dark. Having lights that turn night into day on unfamiliar roads is a fantastic experience. I put Ruby lights on Al my bikes for that reason and experience.

Perfect light for BMW F850GS

Purchased the R4 with Hexcan to provide safety lighting (w/removable yellow lens) and additional illumination when needed with clear lens. Rode 7k miles to Alaska and back with flawless performance. I was well noticed by other drivers even during intense thunderstorms. Installation and setup was easy.

Great Power, Size and Quality

I chose these over Clearwater as it strikes the size/power middle ground that I wanted for my F900 GS. It’s still a compact light but has the power you need if not running 2 sets. Very happy with the build quality.

The R4's delight ;)

I love them. The machining is jewel like precision. They are extremely bright.
