Flos Lighting Installation: Which Setup Works for Your Space?

2026-06-07 by Jane Smith

No Single Answer – It Depends on Your Situation

If you’re looking at Flos lighting – say the IC Lights T1 High pendant or the Aim floor lamp – you probably want that iconic design in your space. But before you buy, the real question is how will it actually get installed?

I’m a quality inspector at a mid-size lighting distributor. Over the past 4 years I’ve reviewed about 200+ fixture installations annually, from high-end residential to commercial projects. And the single biggest issue I see? People assume one installation method works for everyone. It doesn’t. Your electrical setup (and your budget) dictates what’s realistic.

Here’s the thing: the neutral wire – that white wire in a light switch – is the deciding factor more often than you’d think. “What is a neutral wire in a light switch?” I hear that question a lot. Basically, it’s the return path for current. Without it, you can’t use most smart dimmers or some modern LED drivers. And Flos fixtures, especially the ultra-thin designs like the Spotlight Symbol series (yes, that’s a real Flos model), often require a neutral for proper dimming.

So I’ll walk you through three common scenarios. Each one has different wiring needs, fixture options, and potential pitfalls.

Scenario A: You Have a Neutral Wire (Post-2011 Home or New Construction)

If your house was built after 2011 (or you’ve updated electrical since then), you likely have a neutral wire in every switch box. This opens up the most Flos options.

  • Flos IC Lights T1 High – This pendant needs a dimmer for that warm, adjustable glow. With a neutral, you can install a standard Lutron or Legrand smart dimmer. In Q1 2024, I inspected a batch of 15 IC Lights where the contractor skipped the dimmer and used a basic on/off switch. The result? The LED driver flickered constantly. We rejected the install and made them redo it (about $3,200 in labor). Don’t skip the dimmer.
  • Flos Aim – A track spotlight that’s super flexible. The track itself needs a neutral if you want individual fixture switching. But honestly, most Aim installations are on a single wall switch, so no neutral required for basic use. If you want zone control, get the neutral.
  • Marinco Spotlight – This is a competitor brand, not a Flos product. But I’ve seen people cross-shop. Marinco fixtures often accept standard E26 bulbs, while Flos Aim uses integrated LED. The wiring is similar – neutral required for dimming, not for basic on/off.

My advice: if you have a neutral, go for the IC Lights T1 High with a smart dimmer. It’s a stunning piece and the dimming adds real value. Just make sure the electrician actually connects that neutral – I’ve seen them left capped inside the box “because it wasn’t needed.” That’s a $20 fix now, but a headache later.

Scenario B: No Neutral Wire (Older Homes, Pre-2011)

In a 1960s house with no neutral at the switch, you’re limited. The good news: Flos has several options that work fine without a neutral.

  • Flos Bellhop – A portable rechargeable table lamp. No wiring at all. Just put it on a shelf.
  • Flos Snoopy – An iconic table or floor lamp with a simple dimmer built into the cord. That works without any neutral wire. (The floor version is a showstopper.)
  • Flos IC Lights (non-T1) – The original IC Lights (T1 or T2) have a built-in dimmer on the cord. Again, no neutral needed. But the light quality is slightly different from the T1 High – warmer and less adjustable.

I once installed a Flos Taccia (a large floor lamp) in a 1950s living room. No neutral at the wall, so I used the in-line dimmer. It worked fine for a year, then the dimmer failed (overheated because the room was near a radiator). That cost the owner $380 to replace the entire cord assembly. If they’d had a neutral, they could have used a wall dimmer that’s rated for higher temperatures. Learn from their mistake: if you don’t have a neutral, choose fixtures with external dimmers that are easy to replace, and keep them away from heat sources.

Scenario C: Commercial / Track Lighting Setup

For offices or retail, you often see track systems like Flos Aim or Marinco Spotlight. The wiring here is more standardized. A single track run can feed multiple spotlights, but each spotlight may have a small driver that clips onto the track.

Here’s a trick I learned the hard way: the spotlight symbol on wiring diagrams (⚡ with an arrow) actually means “point load” – how much current that fixture draws. I ignored it once on a 50-ft track run and overloaded the circuit. (That was a $2,200 rewire in Q2 2023.) Now I always check the symbol and calculate total load before ordering.

For a commercial space, you’ll typically have a neutral at the junction box. So neutral wire is not a concern – but load planning is. If you’re using Flos Aim, each fixture uses about 20W. On a 15A circuit, you can run up to 10 of them plus a few other lights. Marinco fixtures often have higher wattage (40-60W each), so you’ll need fewer or a dedicated circuit.

How to Know Which Scenario You’re In

  1. Check your switch box – Turn off power, remove the switch plate. Do you see a white wire connected to the switch? If yes, you have a neutral (Scenario A). If you only see black, red, and ground, you don’t (Scenario B).
  2. Age of your home – Built before 1980? Likely no neutral at the switch. After 2011? Almost certainly yes.
  3. Your fixture choice – If you’re set on the IC Lights T1 High, you need a neutral unless you use the cord dimmer version (which is less common). For Aim or Bellhop, it’s flexible.
  4. Professional help – If you’re unsure, get a licensed electrician. A $150 visit can save you $3,000 in rework.

Final Thoughts

Flos lighting is beautiful, but the installation isn’t one-size-fits-all. The neutral wire question is the biggest decider. (And honestly, most homeowners don’t think about it until the dimmer doesn’t work.)

Bottom line: know your wiring, choose your fixture accordingly, and don’t skip the dimmer or the load calculation. If you’re not sure, start with the portable Bellhop or Snoopy – no wiring required, and still a conversation piece. As for me, I’ve started putting a sticker on every Flos box: “Neutral needed for optimal dimming.” Saves us about 50 calls per month.
