A privacy company, built on two decades of LED craft.

Phaseveil is the smart-film brand from NESLight — a New Jersey LED company, established in 2002. We bring two decades of precise, built-in LED design and install craft to your glass, across the NY-Metro area.

Phaseveil makes on-demand privacy for homes and offices.

Smart film that turns the glass you already have from clear to private at a touch, and back again whenever you want.

We’re the smart-film brand from NESLight, a New Jersey LED company, established in 2002, that has designed and installed architectural LED lighting across the NY-Metro area. We don’t make glass and we don’t replace your windows — we enhance the glass you already have. Our film goes onto your existing windows and glass walls, so nothing is torn out and nothing is rebuilt. You keep the windows you have; they just gain a privacy setting you control.

Phaseveil’s smart-film line is new — but the company behind it isn’t.

Established in 2002, NESLight has spent two decades doing exacting, built-in LED work — wall-wash architectural lighting, edge-lit acrylic signage, and LED displays — and now brings that craft across the NY-Metro area. It’s precise, finished work, made to disappear into a high-end interior — the kind of craft you only learn by installing it, year after year, in real homes and offices.

That’s the standard we bring to your glass. Smart film, installed well, is the same discipline as the lighting work NESLight has been doing for two decades: measured precisely, fitted cleanly, and built to look like it was always part of the room.

And there’s only ever one team to deal with. From the first consultation to the measurement, the installation, and the warranty, one company stands behind the whole job — a single accountable vendor, not a curtain installer plus an electrician plus a faceless 800 number. Where licensed electrical work is needed, we coordinate a licensed local contractor as part of that single accountable job — so you still have one number to call, and one team responsible for getting it right.

Smart film, on the glass you already have.

We install smart film on your existing glass. Windows, glass conference walls, partitions — wherever you want the choice between clear and private.

We make your glass switch on demand. Clear when you want the light and the view; private the moment you want it; back again at a touch. No curtains, no blinds, no permanent frosting.

We keep your light and your openness. The whole point of smart film is that you don’t have to trade away the light, the view, or the open feel of a glass-walled room to get privacy — you get both, and you decide which one you want, when.

For homes, there’s also an optional finishing layer: warm, built-in architectural lighting that can make the glass glow when it’s private — the same craft NESLight has installed for two decades. Lighting is optional. Privacy is the point.

Privacy without permanent change.

You shouldn’t have to rebuild a room, replace a window, or give up your light to get the privacy you want. With Phaseveil, the glass you already have gains a setting you control — installed cleanly by one accountable team, and backed by a 5-year warranty on the film and a 3-year warranty on the installation.

That’s the whole idea: your space, exactly as you love it — private the moment you want it, open again the moment you don’t.
