Yes: Sunday Light is a ceiling light made for homes that puts out 34,500 lumens. It's an artificial skylight we make in London: it hangs like a chandelier, and the LED at the bottom of its arm shines up at a sheet 120 cm across, so the room gets all that light as soft brightness from overhead.
Search for anything else over 30,000 lumens and you find warehouse high bays, corn bulbs made for street lights, and one very bright floor lamp. A normal home ceiling light gives about 1,500 lumens.
How bright is a normal home ceiling light?
A typical flush ceiling light gives 1,400-1,500 lumens. Westinghouse's 9-inch fitting is 1,450 lumens; Bulbrite's is 1,400. A 60 W-equivalent bulb is about 800. The UK retailer Lumination puts a whole living room at 3,000-6,000 lumens, counting every fitting and lamp in it.
Apart from Sunday, the brightest ceiling lights sold for homes are the sky-effect fittings. Philips' Skylight gives 3,800 lumens (Medium) or 5,300 (Large), and Govee's Sky Ceiling Light gives 7,000. Beyond that, most of what you find was built for warehouses and streets.
Which lights put out more than 30,000 lumens?
| Light | Lumens | CRI | Built for |
|---|---|---|---|
| Typical flush ceiling light | 1,400-1,450 | 80-90 | Homes |
| Govee Sky Ceiling Light | 7,000 | 95 (at 2700K) | Homes |
| UFO high bay (Sunco, 300 W) | 40,000-49,000 | 70+ | Warehouses, gyms, shops |
| LED corn bulb (GE, 180 W) | 30,000 | Not stated | Warehouses, car parks, street lights |
| Brighter floor lamp | 2,500-60,000 | 95+ | Homes |
| Sunday Light | 34,500 | 97+ | Homes, from the ceiling |
High bays give a lot of light for very little money. Sunco's 300 W UFO high bay is rated 40,000-49,000 lumens for $99.99, with a 90-degree beam and CRI 70+. Maxxima's version gives 40,800 lumens at CRI 80. Both are made to hang over a warehouse, factory or gym floor, and they do that well. CRI 70-80 is what you'd expect there; at home, where you're looking at faces, wood and food, it's low. High-CRI ceiling lights explains why.
Corn bulbs put the same kind of LEDs into a bulb shape. GE's 180 W corn bulb gives 30,000 lumens and replaces a 400 W metal halide lamp in warehouses, car parks and street lights. It has a mogul (EX39) base, the large screw used in those fittings, so it won't go into the E26 or E27 socket of a household light.
Brighter makes the brightest lamp we know of. It stands 6 ft 3 in tall, dims from 2,500 to 60,000 lumens, runs from 2200K to 6500K at CRI 95+ and draws 30-580 W. It was $1,199 in October 2026, on sale from $1,499. Its light comes from a pole that stands in the room.
Why so few home lights go this bright
Lumens cost watts. Even at a high bay's 155 lumens per watt, 30,000 lumens takes about 200 W. High-CRI LEDs give fewer lumens per watt: a CRI 95 ceiling panel gets 4,000 lumens from 40 W, or 100 per watt. Brighter draws 580 W at full power. Sunday draws 400 W.
Much of that power becomes heat inside the LED. A filament bulb throws its heat out as infrared, but an LED gives off almost none, so its heat has to be conducted away from the chip through the circuit board and a heat sink, according to the US Department of Energy. A hot LED gives less light and wears out faster. In the DOE's example, running the chip 11°C hotter cut its useful life from about 37,000 hours to 16,000.
A high bay deals with that heat through a heat sink, hung high above a warehouse floor. A light for a living room has to deal with it a couple of metres above the sofa, for hours at a time.
How Sunday Light runs at 34,500 lumens
The LED sits at the bottom of Sunday's arm and shines up at the sheet. Water flows through the tubes in the arm to cool the LED and carries the heat away from the chip. The loop is sealed and prefilled, so there's no plumbing and nothing to top up. That's what lets Sunday run at full brightness all day.
The sheet scatters the bluer light and reflects the warmer light. It's called Rayleigh scattering, the same thing that makes the sky blue. You look up and see a sky glow with a warm centre, and the room gets soft, indirect light rather than a glare point. It lights a large area with 5,000 lux and more, reaching 10,000 lux at 60 cm, at CRI 97+, and follows a schedule: cool 6000K in the morning, then warmer and dimmer through the afternoon, down to 2650K and 1%. At full brightness it costs about 7 cents an hour to run in the US, or about 10p in the UK.
How many lumens a room needs to feel like daylight works out what 34,500 lumens does in rooms of different sizes.
Will it fit in a normal home?
Sunday hangs like a chandelier from a ceiling rose, and any qualified electrician can fit it in 1-2 hours. Nothing is recessed, so there's no cutting into the ceiling and no roof work. If the room has no ceiling light point, it can be powered by a cable run to a wall socket. It runs on 110-250 V mains, so the same light works in a US, UK or European home with no transformer.
The disc is 120 cm (47 in) across and the light weighs 22 kg (49 lb). You need a ceiling of 240 cm (7 ft 10 in) or more, and below about 260 cm it's best hung over a table or desk rather than a walkway. We install it for $450 in New York, Los Angeles, San Francisco and Seattle, and £450 in London.
Sunday Light, our indoor sunlight fixture, is $6,900 in the US, £5,900 in the UK and €6,900 in Europe, with free worldwide delivery. It ships within 5 working days with a 3-year comprehensive warranty covering all components.
