(NLD) On The Road X4M Gen 5

This is the 2nd light from On The Road’s X4 series of lights. I’m putting slightly more time into this as I couldn’t find any information about these, in case someone else is also interested in getting one.

Apparently this particular model (and others in it’s series) is the 5th generation, with all-new emitter choices, although I have no idea who’s the manufacturer as they just provide the model names and specs (which I’ve included in the photo reel)

This is a single emitter light with a M50-F9 chip in 6500k CCT, with a claimed output of 5000(!) lumens on turbo, **and** paired with a constant current driver on top. If you’re curious about other specs, do check out the included spec sheet. There is also another chip labeled the 7070 with a smaller die area that seems to be designed for throw, but in this particular host’s design, it seems moot, more on that later.

Like it’s (slightly taller) brother, it’s a very small light, one of the slimmest and lightest amongst my 21700. Yet, it still features modern comforts such as USB-C charging, although it lacks the tail magnet that’s found in the bigger brother, which is a curious omission in my POV (cost cutting perhaps)

This unknown LED seems to be pretty efficient, similar to the M35 featured in it’s sibling, with a relatively blue temp but no discernable green/magenta tint even when compared to other chips like the Nichia 519a.

With a shallow orange peel reflector and a large chip, this light is pretty floody in it’s beam profile, with a small hotspot and very wide spill area. Even with such a floody beam, it’s brightness is pretty comparable to my other lights such as the TS26S and X4 Stellar in 5000k. That green ring you see lining the reflector is a glow-in-the-dark o-ring, which is a pretty neat addition.

In terms of performance, it’s similar to the brother by sustaining the highest ramp (non-turbo) for almost 10 minutes without any apparent stepdowns in brightness, while being only slightly warm to the touch. As I don’t have any measuring equipment, do treat these observations with a grain of salt.

The less common UI of click to on, hold to off is also present in this light, and whether this is a negative will depend on user preferences. The light is only sold as a set with an included 5000mah battery, which I measured to be accurate my XStar charger’s grading mode.

All in all, this is a pretty interesting offering from a brand that’s been around for several years, yet only seems to have attention mainly in the Chinese market.

I’m keen on getting some hands-on time with the 3rd one in the series, the X4 which is designed for throw with a deep reflector design, but I can’t seem to find it on sale anywhere (the AliExpress listing is discontinued). Thanks for reading and hope my (non-technical) observations are helpful!
