Hundreds to thousands of light points brought flush through a tensioned membrane, fed by one LED illuminator sitting in a closet. The star field itself puts no power above the ceiling, and with the room lights up the tips are hard to pick out.
A fiber optic star ceiling is a tensioned membrane ceiling with optical fiber tips brought through its face, one tip per star. The light source is a single remote LED illuminator that can sit thirteen feet away in a closet, above a cabinet, or behind an access hatch. Longer runs are possible and the limits are in the design guidance below. Light travels from that illuminator down PMMA fibers to the ceiling plane. Nothing above the membrane carries current. The fiber carries light only, so there is no diode at the ceiling to fail and no fixture to open. The light source and its heat stay at the illuminator. Effects live at the illuminator: a mechanical twinkle wheel for a wandering, organic shimmer, an RGBW engine for color, and a dedicated bundle on its own channel for shooting stars.
This is where it differs from a recessed fixture. Any recessed fixture puts a lens, a trim ring, and a heat sink in the ceiling plane, and all three are visible the moment the room lights come up. Our tips are 0.75 mm to 2.0 mm, cut flush with a hot blade, and the PVC closes around them. From eight feet, unlit, in a matte membrane, they are hard to pick out. That is our own observation across our installs, not a measured result. On a large commercial project we build a mockup so you can judge it yourself. When the room goes dark the sky comes on. We weld the membrane and bend the perimeter profiles on our own CNC in Dania Beach, which means the star field can follow a curve, sit inside a cove, run through a printed nebula, or wrap a dome, and it all arrives from one drawing set with one crew. We have been installing stretch ceilings in South Florida since 2014.
The only powered component in the star system is the illuminator, and it lives in a closet or behind a hatch. Above the ceiling the star system is fiber and air. If the design adds a cove, a linear light or speakers in the same ceiling, those bring their own low-voltage wiring, and we show it on the drawings. No powered device at the tip, no driver at height, no lamp to change over a bed. When something eventually needs attention, a person opens a closet door instead of scaffolding a room.
Tips are cut flush with a heated blade and the tensioned PVC grips them. In a matte membrane, unlit, at normal viewing distance, the field is hard to pick out. That is our own observation, not a measured result. There is no trim ring, no lens, no visible grid of dots. The ceiling reads as one clean flat plane by day and as a sky at night, on its own control channel.
We bend our own profiles, so the star field is not stuck inside a rectangle. It can sit inside an AP-302 cove halo, fill a floating oval built from AP-216, run across a curved soffit, or come through a printed membrane so a painted nebula gets real points of light in it. Constellations are plotted 1:1 from an actual star chart for a date and a location you choose.
The spaces where we install this system most. The rest of the range is on the lighting systems page.
Where the star field is the only thing lit while the projector runs and needs to be on a separate scene from the cove.
Ceilings directly over a bed, where no client wants a powered fixture, a heat source, or a lamp change above their head.
Massage rooms, relaxation suites, and indoor pool enclosures, with the illuminator kept dry in an adjacent space and only fiber crossing into the humid room. Damp and wet location requirements are set by the electrical engineer and the AHJ. We hold no wet location listing for any part of this assembly.
Usually with a constellation plotted for a specific birth date and city so the ceiling means something.
Lounges and dining ceilings where the star field sits inside a cove halo or a floating shape rather than a flat rectangle.
Feature ceilings including curved and domed soffits where a fixture layout would never resolve cleanly.
The build runs in a fixed order, and the order matters more here than on any other ceiling we do, because once the membrane is tensioned there is no going back above it without dropping it.
These are shop standards from our own installs, not laboratory data. We hold no photometric test data for this system and we will not pretend otherwise. What follows is what we build to.
4 in above the finished ceiling plane is the absolute minimum for routing fiber and keeping bends legal. 6 to 8 in is comfortable and is what we ask for. Go to 10 in if a cove profile, a shooting-star bundle, and acoustic absorption are all sharing the same cavity. Below 4 in the fibers start getting bent tighter than they tolerate and you will see dimmed or dead points.
Keep every bend at 2 in radius minimum, 3 in preferred where the harness gathers. End-glow PMMA does not fail loudly when you kink it. It just goes dim at that one point, and by then the membrane is up.
Worked examples: a 12 x 15 ft home theater (180 sq ft) reads full at 300 to 450 points. A 14 x 16 ft primary bedroom (224 sq ft) is right at 200 to 250, because dense reads busy over a bed. A 400 sq ft spa ceiling with a Milky Way band usually lands between 900 and 1,200 points.
A single diameter reads as a grid of dots. A real sky has magnitude. Our default mix is roughly 60 percent at 0.75 mm, 25 percent at 1.0 mm, 12 percent at 1.5 mm, and 3 percent at 2.0 mm. Reserve the 2.0 mm fibers for named stars and the anchor points of any constellation you are plotting.
The illuminator is the only serviceable part, so it has to be reachable without opening the ceiling. Allow a clear zone of roughly 12 x 12 x 6 in for the unit plus another 6 in in front of it for the harness sweep and airflow. Closet shelf, above a cabinet, soffit with an access hatch, or the adjacent mechanical room all work. Two things designers get wrong: a mechanical twinkle wheel has a motor, and in a genuinely quiet room you can hear it, so do not put the unit above the bed head or directly above the theater listening position. Keep it 10 ft away, or specify an engine with electronic twinkle and no wheel (more uniform shimmer, silent, less organic).
13 ft is the standard harness. 16 to 20 ft is workable. Past 20 ft the tips at the far end start visibly losing brightness against the near end, and the fix is not a bigger illuminator. Split the field across two illuminators instead. Also note that splitting has a side effect worth using on purpose: two illuminators means two independently controllable zones.
Color is set at the illuminator, not at the fiber. Every fiber fed by one illuminator changes color together, always. If the design calls for a warm field over the seating and a cool field over the bar, that is two illuminators and two harnesses, and it has to be decided before any fiber goes above the ceiling.
Ten to sixteen fibers laid in a line, spaced 5 to 8 in apart, fired in sequence on their own channel. Fewer than ten reads as blinking dots. Spacing tighter than 5 in reads as a smear. This bundle is pulled separately at layout stage and cannot be retrofitted.
In-ceiling speakers, sprinkler heads, and diffusers get reinforcing rings bonded to the membrane and are set before the star map is transferred. Get those locations to us at the RCP stage. Membrane goes up after paint and after everything above it is finished, and it is the last trade in the room.
On large commercial projects we build a physical mockup panel before you commit. Density, diameter mix, twinkle speed, and membrane finish are all decisions that are easy to make in a dark room with a real sample and nearly impossible to make from a rendering.
No, and we will not hand you one. We hold no IES, LM-79, LM-80, or TM-21 data for this system, and no measured lumen, lux, or footcandle figures. A star field is a decorative point-source effect, not an illumination layer, and it should not be counted toward any lighting calculation on your drawings. Design your levels with the specified downlights, cove, or backlit ceiling, and treat the star field as its own scene on its own channel. What we can send is the membrane light transmission test report (42.0% diffused, 70.5% transparent, Poznan University of Technology, method per CIE 130-1998) if the same ceiling also carries a backlit element, and on a large commercial project a physical mockup can be arranged so the effect gets approved by eye instead of by simulation.
4 in above the finished plane is the minimum for routing fiber at a legal bend radius. 6 to 8 in is what we ask for. Take it to 10 in if a cove profile, a shooting-star bundle, and acoustic absorption are all in the same cavity. The illuminator is remote and must be reachable without opening the ceiling: a closet shelf, above a cabinet, a soffit with an access hatch, or the adjacent mechanical room. Allow roughly 12 x 12 x 6 in for the unit plus 6 in clear in front for the harness sweep and airflow. Keep the harness under 20 ft. Past that, split the field across two illuminators instead of extending the run.
Not from normal viewing distance in a matte membrane. Tips are cut flush with a heated blade and the tensioned PVC closes around each fiber, so unlit they read as almost nothing at eight feet. Finish matters: on a gloss or mirror membrane the flush cut reads as a matte speck against a reflective surface, which makes the field findable in daylight. Matte is our standard for star ceilings, satin is fine, and if you specify gloss we will build it but we will flag it first.
Shop standard density is 0.5 to 1 point per sq ft for a subtle accent, 1.5 to 2.5 for a full night sky, and 4 to 6 inside a Milky Way band with a sparse field around it. A 12 x 15 ft home theater usually lands between 300 and 450 points. They should not all be the same size. We mix diameters at roughly 60 percent at 0.75 mm, 25 percent at 1.0 mm, 12 percent at 1.5 mm, and 3 percent at 2.0 mm, because a single diameter reads as a grid of dots rather than a sky. The 2.0 mm fibers are saved for named stars and constellation anchor points.
Color changes at the illuminator, never at the fiber. Every fiber fed by one illuminator changes together, always. Two independent color zones means two illuminators and two harnesses, and that decision has to be made before any fiber goes above the ceiling because the bundles are pulled separately at layout stage. Same for shooting stars: that is its own bundle on its own channel and it cannot be retrofitted after the membrane is up.
It can be serviced. The membrane clips into a perimeter track and our crew can drop it and re-tension it for any work above the ceiling. In practice it rarely comes to that, because the only powered component in the system is the illuminator and it is already sitting in a closet or behind a hatch. There is no driver, no diode, and no heat at the ceiling plane, so there is nothing up there to fail. We also hand over a marked-up plot of the final star map so whoever opens this ceiling in ten years knows exactly what is above it.
What we hold today and issue on request. The published files sit in the lighting technical library.
Reserved and not yet published. Listed by name so nobody assumes it exists:
What we do not have, said plainly and by name so it does not surface at submittal: we hold no LM-79, LM-80 or TM-21 data and publish no IES files for this system. We hold no NFPA 701, no NFPA 286 or 265, no ASTM E2573 mounted-assembly test, no UL 2043 plenum rating, and no Florida Product Approval or Miami-Dade NOA for this assembly. We hold no NRC or ASTM C423 absorption data for this ceiling. We hold no wet location listing for any part of it. The ASTM E84 report covers the membrane per finish on white specimens and the laboratory assigned no classification to those results. Send us your specification section at drawing stage and we will tell you straight, in writing, which of those we can meet and which we cannot.
Our profile cross-sections, dimensions and the full color chart live in the technical library. CAD files are sent on request, usually within one business day.
A panel manufacturer sells tiles, panels and modules with fixed edges, sized by what their tooling already makes. A star field is not a module. Because we fabricate the membrane and bend our own profiles, we can put one inside a curved cove, across a dome, through a printed nebula, or over a spa where nobody wants a powered fixture at all, and the same shop that draws it welds it and installs it in South Florida.
