Focal Point Lighting: 7 Questions You Should Ask Before Your Next Commercial Project

What We're Covering Here

I've been a quality and brand compliance manager for commercial lighting for about four years now. In that time, I've reviewed over 200 unique product specs annually, and I've rejected maybe 12% of first deliveries in 2024 alone, mostly due to inconsistencies in light distribution and finish. So when it comes to Focal Point products—or any commercial lighting, really—I've developed a pretty sharp eye for what matters and what's just marketing fluff.

This article isn't a sales pitch. It's a straight-up FAQ based on questions I've heard from project managers, contractors, and facility managers who are trying to figure out if Focal Point is the right fit for their job. Here are the questions you're probably asking:

• What's the deal with “focal point” and lenses in your products?
• Is a concave lens the same as a diverging lens?
• That shell chandelier looks great, but is it practical?
• How do I install a Charleston chandelier without messing it up?
• Where exactly do I attach the ground wire on a light fixture?
• Is Focal Point's one-stop solution actually reliable?
• When should I not choose Focal Point?

Let's get into it.

1. What's the deal with “focal point” and lenses in your products?

The name isn't just a clever branding exercise. Focal Point's core technology is precision optics. We design lenses (both concave and convex) to control light distribution with a level of accuracy that most general-purpose LED fixtures don't bother with. For commercial spaces like offices or retail floors, that means you can get uniform illumination without harsh hotspots or dark corners.

If I remember correctly, our internal spec for beam angle tolerance is ±2 degrees, which is tighter than the industry norm of ±5 degrees. That kind of consistency matters when you're lighting a large area with multiple fixtures—you don't want one panel looking noticeably different from the next.

2. Is a concave lens the same as a diverging lens? And what about the “focal point” inside?

Technically, yes: a concave lens is a diverging lens. It spreads light rays apart, which is useful for wide-area illumination or for creating a specific beam shape. The tricky part—and this is where I've seen specifiers get confused—is that the physics of a concave lens means the focal point is virtual. That is, the light rays don't actually converge at a point; they diverge, but if you trace them backward, they appear to come from a point behind the lens. So when we talk about a “focal point” in a concave lens context, we're referring to that virtual focal point.

In our products, concave lenses are often paired with convex elements to create complex beam patterns. For example, some of our downlights use a combination to produce a wide, even spread without glare. That said, if you're looking at a Focal Point product and you see “concave lens” in the spec, just know it's about controlling light, not magnifying it.

Looking back, I should have documented this better for our spec sheets. At the time, we assumed everyone understood the optics terminology. They didn't.

3. That shell chandelier looks great, but is it practical for a commercial lobby?

The shell chandelier is one of our most popular decorative lines. It's designed for hotel lobbies, restaurant entrances, or high-end retail spaces where aesthetics matter as much as function. The practical question is: will it hold up?

From a quality standpoint, I can tell you we've tested these fixtures for salt spray (to simulate coastal humidity) and thermal cycling (to simulate temperature variations in conditioned spaces). The shell material is a polycarbonate composite, not real shell, which means it won't yellow or crack as easily as some natural materials. But here's the catch: it's still a decorative piece. If you're looking for a workhorse fixture for a 24/7 operation, this isn't it. The lamping is modular, but the decorative elements are delicate.

So, yes, practical for a high-traffic lobby where maintenance is regular. Not practical for a warehouse or a parking garage.

4. How do I install a Charleston chandelier without messing it up?

The Charleston chandelier is a more traditional, multi-arm design. The biggest installation mistake I see—and I've seen it in the field—is not accounting for the weight distribution. These fixtures can be heavy (some models up to 40 lbs), and the canopy needs to be secured to a properly rated junction box.

Here's a quick checklist I use:

• Verify the ceiling junction box is rated for the fixture weight (look for the stamp).
• Make sure the crossbar is aligned correctly before hanging.
• Thread the wires through the threaded nipple before you attach the canopy.
• Don't skimp on the torque for the mounting screws. Hand-tighten, then give it an extra quarter turn.

And yeah, the wiring is straightforward, but the next question covers the part that trips up most people.

5. Where exactly do I attach the ground wire on a light fixture?

This is one of those questions that sounds simple but causes a lot of hesitation. The answer depends on whether you're working with a metal or plastic fixture, but the principle is the same: the ground wire connects to the fixture's grounding point, which is usually a green screw or a copper wire coming from the fixture's chassis.

For a typical Focal Point fixture:

• Metal fixtures: There's almost always a green grounding screw on the mounting bracket or crossbar. The ground wire from your building's supply should be looped around that screw, then connected to the fixture's ground wire (if it has one) with a wire nut.
• Plastic/insulated fixtures: These may not have a grounding screw. Instead, they'll have a bare copper ground wire that you wire-nut to the supply ground.
• Under federal law (18 U.S. Code § 1708), only USPS-authorized mail may be placed in residential mailboxes. That's not directly relevant here, but it's a good reminder that electrical codes are similarly strict. In fact, the National Electrical Code (NEC) requires that all metal fixtures be grounded. So if you're unsure, check for the ground wire—always.

I've rejected a batch of fixtures because the ground wire wasn't long enough to reach the junction box. The vendor claimed it was “within industry standard.” It wasn't. Now every contract I write specifies a minimum ground wire length of 6 inches beyond the canopy.

6. Is Focal Point's one-stop solution actually reliable?

Focal Point positions itself as a one-stop solution—commercial LED, decorative fixtures, lenses, and even smart lighting controls. From a procurement standpoint, that's appealing. Fewer vendors means fewer coordination headaches. But from a quality control perspective, I'd say it works for about 80% of projects. If your project involves highly specialized requirements—like museum-grade color rendering (CRI 98+) or extreme dimming ranges (below 1%)—you might need to mix vendors.

That said, our controls integration is solid. We use standard protocols (DALI, 0-10V, and some proprietary stuff), and we test interoperability before shipping. So for most offices, hotels, and retail spaces, yes, the one-stop model works.

7. So when should I not choose Focal Point?

Here's where the honest limitation comes in. I recommend Focal Point for commercial interiors where the visual environment matters—offices, hospitality, retail, showrooms. But if you're dealing with:

• Industrial environments (high dust, vibration, corrosive atmospheres)
• Outdoor applications (we do have some weather-resistant products, but it's not our core strength)
• Budget-constrained projects where you need the absolute lowest price point

Then you might want to look at alternatives. In my first year, I made the classic error of assuming our fixtures could handle a covered outdoor patio. The condensation damage was not covered under warranty, and the client was not happy. That was a $3,200 lesson for me (not my company—I was the one who had to negotiate the replacement). So I'm upfront about that.

If I could redo that decision, I'd have pushed for our weather-rated line from the start. But given what I knew then—nothing about that specific installation's humidity profile—my choice was reasonable. You live and learn.

That's it. No grand summary. Just answers to the questions I hear the most. If you've got another one, drop it in the comments or contact our support team. I read every spec question that comes through—and I'll tell you, honestly, if our product is the right answer.
