Flat-Profile Flashlight Showdown: Olight ArkPro Ultra vs. Milwaukee 2016R
Olight ArkPro Ultra vs. Milwaukee 2016R Flashlight Comparison
Today, we’re pitting two modern, flat-profile EDC lights head-to-head to see which deserves a permanent spot in your tool belt: the Olight ArkPro Ultra and the Milwaukee 2016R. Both lights ditch the classic cylindrical design for a slim, pocketable footprint, but they take very different approaches once you turn them on.
Let’s break down the core specs and pricing:
Price:
The Olight ArkPro Ultra comes in at around $100–$110, while the Milwaukee 2016R sits at a more budget-friendly ~$70.
Size & Weight:
The Olight is slightly more compact at 4.88 inches long and ~4.2 oz, compared to the Milwaukee at 5.27 inches and ~5.0 oz.
Belt Clip:
Both flashlights have belt clips, the Olight has a two-way/pocket clip to allow the flashlight to sit deep in your pocket but its dual-direction design allows it to clip onto the brim of a baseball cap for hands-free headlamp use or secure tightly onto a belt, vest, or backpack webbing. The Milwaukee clip alows the flashlight to sit deeply in your pocket.
Brightness & Beam:
Olight pushes 1,700 flood / 800 spot lumen via dedicated dual emitters. It features a floor light option and a spot with halo option. Milwaukee delivers 1,300 lumen in Boost mode through a single variable flood light beam.
Charging:
Both flashlights have a USB-C port, and a rubberized dust port cover. OLight charging port cover is better designed and seems more durable. OLight charging port cover is better designed and seems more durable. Olight also can be charged with their magnetic proprietary charger. Both lights have LED indicators for battery light.

UV Light Option |Olight
The Olight ArkPro Ultra additionally features a ZWB2 “Black Glass” filter over the UV emitter. This is a game-changer for inspections: standard UV LEDs can leak visible purple light that washes out contrast, while the ZWB2 filter blocks that unwanted “noise,” making it much easier to spot Weld-On P-68 UV Glow Primer during plumbing inspections.
While the primer appears clear to the naked eye—avoiding the messy purple stains associated with traditional products—it glows a vibrant purple under UV light. This makes it easy to quickly and professionally confirm that the pipe has been properly prepared for a secure bond.
Furthermore, the independent laser button allows you to operate the Class 1 green laser simultaneously with any other light source. That’s a really nice feature!
Green Laser:
Both lights offer a green laser side switch that can be turned on and operated in conjunction with the flashlight. To the naked eye Olight seems brighter while Milwaukee seems crisper and cleaner.
Durability:
Milwaukee is rated slight more robust at IP67 and a 6-foot drop rating. Olight brings IPX7 waterproofing, 6-foot drop protection, and an O-Aluminum body for high scratch resistance. When it comes to real-world operation on the jobsite, Milwaukee is way more intuitive and easier to use. There’s no learning curve—just pick it up, hit the button, and you have light. Olight gives you tons of features, but navigating between all the modes takes a little getting used to and I found myself fusing with the selector lever when wanting to turn on the flashlight.
Where that extra complexity pays off on the Olight ArkPro Ultra is raw versatility.
Meanwhile, Milwaukee doubles down on practical trade tools. Beyond simple USB-C charging and robust IP67 dust/water protection, it includes a laser-etched imperial and metric ruler right on the housing. It’s a great touch, though in future versions, I’d love to see Milwaukee take it even further by integrating a small torpedo level bubble and a dual magnet setup on the body to make hands-free layout work even smoother.
Final Thoughts
If you want maximum features, inspection UV tools, and premium scratch resistance, the Olight ArkPro Ultra is a tech-packed option at around $100. But if you want a ~$70 everyday carry light that is way more intuitive, easier to use, robust and built for simple jobsite utility, the Milwaukee 2016R is tough to top.
Which one are you throwing in your pocket? For me I’m reaching for the Milwaukee for the fast simple operation.
