If you are a permanent jewelry artist, you know how crucial it is to have a clear, safe view of your welds. Sunstone Engineering recently launched the Halo Auto-Darkening Lens (ADL), an all-in-one optical solution featuring built-in LED lights, magnification, and a heavy-duty pivoting arm.
But is this high-tech lens actually worth the investment for permanent jewelry welding, or should you stick to other popular optical options? We break down the Sunstone Halo section by section based on our hands-on review.
First Impressions: Unboxing the Sunstone Halo
We are unboxing, assembling, and taking Sunstone Engineering’s recently launched Halo auto-darkening lens for a complete test drive.
The Halo is designed specifically to combine high-level magnification with active eye protection and brilliant illumination, all mounted on a highly adjustable pivoting arm. Out of the box, we’ll see if this sturdy system lives up to the hype for permanent jewelry welding.
An Overview of the Hardware
Right away, the physical quality of the Halo stands out.
From the moment you handle the components, it feels remarkably robust, sturdy, and solid.
It features metal swivel joints and heavy-duty arm segments designed to handle daily studio wear and tear. Rather than feeling like a flimsy desk lamp, the Halo is an incredibly stable piece of professional equipment.
Setting Up and Assembling the Arm
Setting up the Halo is straightforward. The unit features an adjustable mounting clamp that secures tightly to your workspace.
To demonstrate its impressive reach, we clamped the base on the far side of a workbench; the arm easily extends across the entire table without tipping or losing stability.
The pivot points feature satisfying, audible clicks as they rotate, allowing you to position the lens exactly where you need it.
Once the arm is mounted, you simply peel off the protective film from the large magnifying glass, and you are ready to adjust.
Dialing in the Angles: Fine-Tuning the Joints
One of the best design aspects of the Halo is its locking capability.
The package includes an Allen key, which you use to tighten and secure every single joint on the pivoting arm. By tightening the bolts on both ends of the dual arms, you can lock the lens into incredibly strange, dramatic, or steep angles.
Unlike lower-quality arms that sag or slowly drift downwards under their own weight, the Halo holds its position perfectly, giving you complete confidence that it won’t move mid-weld.
Close-Up on the Lens
Looking through the lens reveals a massive, crystal-clear magnifying glass.
The magnification power on the Halo is huge-similar to what you would experience through a traditional welding microscope. However, the Halo offers a massive advantage over a standard microscope: it provides significantly more physical clearance and workspace flexibility underneath the lens, making it much easier to maneuver your hands, chains, and grounding pliers.
Connecting the Halo to Your Welder
Connecting the Halo to your welder is incredibly simple. The connection cable is exceptionally long, which is very tactical and a fantastic design choice. A long cable means you can place your heavy welder further away or under your desk, keeping your immediate tabletop clutter-free while the Halo swings out freely over your work area.
To connect it:
- Plug one end of the cable directly into the Halo ADL.
- Plug the other end into the “optics” port on your welder (in this review, we are using the Zap Plus 2 welder).
- Power on your welder.
As soon as the welder is powered up, the Halo’s built-in ring of LED lights automatically illuminates. These lights are incredibly bright, providing professional-grade lighting directly over your welding point.
Let’s Weld!
With the Halo securely connected and illuminated, we put it to work.
When you initiate a weld, the auto-darkening lens instantly reacts to the spark, switching from clear to dark in a fraction of a millisecond to protect your eyes. Combined with the magnification and bright ring lights, aligning the jump ring and holding the chain is smooth and highly precise.
The Honest Review!
So, is the Sunstone Halo worth it? Here is our honest assessment of the pros and drawbacks:
👍 The Pros:
- Exceptional Build Quality: The unit is extremely solid, well-made, and dependable.
- Huge Magnification with Clearance: You get microscope-level magnification without losing the physical space needed to guide your hands and jewelry tools easily.
- Highly Adjustable & Secure: The pivoting arm is incredibly easy to move but locks rigidly in place once tightened.
👀 The Drawbacks:
- Tedious Adjustments for Fast-Paced Events: If you are working a busy pop-up event with a long line of clients, adjusting the height and angles of the arm in between different jewelry setups (e.g., switching from a wrist height for a bracelet to a low stool for an anklet) can be time-consuming. For fast-paced events where quick height changes are common, more compact and highly versatile alternatives like the Sunstone Eclipse or Sunstone Shades might be more convenient.
- The Magnification Sweet Spot: Because the magnifying glass is quite large, there is a physical trade-off: if you bring your hands too close to the lens, you lose some of the focused brightness of the LED lights; if you pull them too far back, the magnification can feel a bit too intense.
👏 The Verdict: If you do a lot of studio work where your welding station remains at a consistent height, or if you have vision challenges and need substantial magnification, the Sunstone Halo is an absolute game-changer that you will love! However, if your business is primarily fast-paced pop-up events where you constantly need to pack up, travel, and adjust heights on the fly, the Eclipse or Sunstone Shades may offer a bit more versatility.
💡 Pro Tips for Using the Sunstone Halo
To get the absolute most out of your Sunstone Halo, keep these professional tips in mind:
- Find and Memorize Your “Sweet Spot”: Since the large magnifying lens has a specific focal range, take a few minutes before you start working to find the ideal distance where your workpiece is perfectly magnified and fully illuminated by the built-in LEDs.
- Pre-Set Your Event Heights: If you do choose to take the Halo to events, pre-arrange your seating and table heights. For example, have your client sit at a specific height so that you can simply swing the Halo horizontally into place rather than needing to loosen and adjust the vertical height joints between every single client.
- Maximize Workspace Cleanliness: Take advantage of the Halo’s extra-long connection cable. Mount your welder out of sight (or off to the side) to keep your physical workspace clean, uncluttered, and spacious for your clients.
- Use the Allen Key Wisely: Keep the provided Allen key close at hand. Tighten the joints firmly enough that the arm holds steady at any awkward angle, but leave just enough tolerance on the main horizontal pivot points if you plan on swinging the lens out of the way frequently.
