Description
A room at night is a lighting problem before it is anything else. The Nebula Cube solves it by turning a single USB socket into a ceiling of stars, projected through an optical lens and a patterned film rather than through a diffused LED. That difference is why the dots have edges. A diffused lamp gives you a glow. A focused projector gives you a sky.
The body rotates through a full 360 degrees, so the projection can travel across a wall, sit on a ceiling above a bed, or be aimed at a corner to fake depth in a small room. Touch controls handle power, mode and brightness, which means the whole interface is one button and no remote to lose. Modes shift the projection between star fields and nebula wash, and brightness dims far enough down that the room stays usable for sleep rather than turning into a nightclub.
It runs from USB at 3 to 6 volts, so it works from a wall adapter, a laptop, a power bank, or the USB port on a monitor. Nothing in it needs a battery to be replaced and nothing needs an app to be paired. That simplicity is deliberate: the version of this product people actually keep on a nightstand is the one that turns on with a tap at 1 a.m. without a phone, a password or a firmware update.
Colour temperature and throw distance decide how it reads. Placed two to three metres from a wall, the projection spreads wide enough to fill the surface without breaking into individual hotspots. Closer in, it becomes a dense field for a small bedroom or a reading corner. The unit is small enough to sit on a shelf and light enough to move between rooms, which in practice is how it gets used.
Light is not decoration. It is the first thing a room says.

Where it belongs
Bedrooms, kids rooms, dorm rooms, a home cinema corner, a gaming setup that needs backlight without glare, and any rented flat where you cannot put a nail in the wall. Photographers use it as a cheap star-field backdrop for portraits. Parents use it as the night light that gets a child to sleep without a fight. It also works as a gift that does not need instructions, which is rarer than it should be in lighting.
Questions buyers actually ask
Q: Does it need a battery?
No. It runs from USB power, so a phone charger, a laptop port or a power bank all work. That means no battery to replace and no dead unit on the nightstand.
Q: Is it bright enough to light a room?
It is a projector, not a lamp. Output is under 60 lumens, which is aimed at atmosphere and sleep rather than reading. If you need task lighting, use a separate lamp.
Q: How far should it be from the wall?
Two to three metres gives the widest, cleanest field. Closer placement makes the pattern denser and brighter, which suits a small bedroom or a reading corner.
Q: Can it cover a whole ceiling?
Yes, the body rotates through 360 degrees, so you can aim it upward from a shelf or a bedside table. Ceiling coverage depends on distance and on how flat the surface is.
Q: Is it safe to leave on overnight?
The unit runs at low voltage from USB and is CE certified. Most people use the lowest brightness setting overnight, which is what the dimming range is designed for.
Q: Which colour configuration should I pick?
Choose the configuration that matches the palette of the room. Warmer projection suits bedrooms with wood and fabric, cooler projection suits white walls and gaming setups.
