Sega Toys Homestar Flux Home Planetarium

BlissLights Sky Lite Laser Projector

Laser Stars Twilight Projector

This elegant yet easy-to-use planetarium projector features a three-setting automatic timer mode that allows the user to choose between 15, 30 or 60 minutes of operating time. One of the most interesting aspects of this projector is its ability to project 60,000 stars onto your walls and ceiling.

The Sega home planetarium is fairly compact and rests on a metal stand. It is very easy to transport from one room to another as it weighs only about 0.8 kg. On the back of the unit, you will find the projection disc slot as well as 4 control buttons (on/off switch, timer, motion and shooting star option) which are backlit for easy use in a dark room.

On the front of the star projector, you will find the glass lens surrounded by a ring. The ring is used to control and adjust the focus. The unit uses a warm white LED bulb to create the perfect starry night at home. We particularly like the “shooting star” mode which really makes this projection of light come to life and gives us that “cosmic” feeling.

The star projector comes with 2 interchangeable projection discs of the northern hemisphere sky (one with constellations and one without), although there are about 30 more available for purchase if you want more.


It is undoubtedly a very high-quality planetarium projector and that is reflected in the price. However, it is made of strong and durable materials and the images projected on the walls are sharp and crisp. It is really easy to use and the device works very quietly. It’s definitely a lovely item for any space enthusiast.

The design of the Sky Lite is different from the typical globe shape that you can find on most planetarium projector. Its unique shape allows you to tilt it from a 45-degree angle for wall projection to a 90-degree angle for projecting its visual goodness on your ceiling.

The unit projects a patented blue nebula cloud effect through its aperture, allowing your bedroom or living room to shine in a special way. You will find three control buttons on the side of the unit: the on and off switch, adjust the brightness level and control the motion.

There are 4 different effects available. The normal one is a field of drifting stars against a moving nebula background, and the pulse mode (which is not really impressive). Additionally, you can choose to only display the stars or the nebula cloud.

To create this holographic light show, the sky lite uses a direct diode laser combined with a high-quality optical glass lens. Although the brightness level is satisfying, the visual effects will be much more impressive in a dark room. Regarding space coverage, the device does cast its visual goodness over a very wide area.


Sky Lite from BlissLights is an affordable star projector that is ideal for anyone wanting to create an outer space / relaxing feeling in their humble abode. We wished that the device had more colour options. However, the visual quality of the projected nebulae, starfields and auroras is mesmerising on any background. It is rated as one of the best starry night light projectors by Amazon’s e

This home planetarium essentially projects a blue nebula cloud that the manufacturer calls “Twilight” along with a constellation of green stars moving slowly in and around. Although it works well in a room where the light is dimmed, the projector works best in a room where all the lights are off. 

The holographic show covers a fairly large area and perfectly simulates a beautiful night sky (aurora borealis on a starry background). The star-shaped head can swivel up and down, giving you better control of the projection angle compared to other planetarium projectors available on the market. 

Don’t be fooled by its appearance. Although the design looks like a star and the outer casing is made of plastic, it is not a children’s toy. It uses lasers to project stars onto the wall or ceiling, which means it should only be operated by adults. If you buy it for younger children, make sure you place it somewhere they cannot reach it.


All in all, it’s a great device if you’re looking to light up your home cinema for movie nights, create a relaxing atmosphere for your meditation session, or set up a romantic vibe for a date night. It is also a fantastic gift for your friends who love space or for a family member who is interested in astronomy.

This device is probably best described as a star projector for kids, and this is reflected in the overall toy-like design of the device which closely resembles R2-D2 from Star Wars. That being said, many parents use this projector as an educational tool to help their children discover the many wonders of the universe

The brainstorm planetarium can be used in 2 different ways. The first way is the planetarium mode which projects rotating stars and constellations into the room. It creates an “outdoor space” atmosphere in your children’s room, but it can also be used as a night light to comfort and soothe your child while they sleep.

The second way to use this device is to simply project still images onto the wall or ceiling. The device comes with 3 interchangeable slide discs, each containing 8 images, for a total of 24 space images. These images are various images taken in space by NASA and the Hubble Space Telescope.


While this modest home planetarium won’t blow your mind, it’s a great little gadget: it’s easy to use, very affordable and virtually silent. We can say with certainty that this projector will certainly please any young person dreaming of one day walking on the moon.

The Smithsonian Optics Room Planetarium is another projection device that should be seen more like a toy for children rather than a collector’s item for space lovers. Like most planetariums in this price range, the outer casing is made of plastic. The device is mounted on a swivel bracket that allows the user to tilt the projector up or down.

At the top of the unit, you will find 3 control buttons and two openings. The large aperture projects a rotating star pattern that can be used to give children some calming down time before bedtime. The smaller one projects images from one of the 3 interchangeable discs. You can display a clear view of the 50 available images of astronauts, spaceships, planets, nebulae, galaxies and other deep space objects. The apertures are surrounded by a focus ring that allows you to control the sharpness of the image depending on the distance between the projector and the wall or the ceiling. At the bottom, you will find a storage space for the 3 discs. 

The star projector is powered by 4 AAA batteries, so there is no extra wire. The projector switches off automatically after 15 minutes, which is handy to avoid discharging the batteries too quickly.


Although we think this device is a little overpriced, it has an average rating of about 3.9 out of 5 stars, across more than 300 reviews. So it seems that this planetarium projector does its job well. It is not the most advanced device on the market, but you can be sure to make a friend or family member who loves space very happy at Christmas or on their birthday.

5 Important criteria to consider when buying a home planetarium

1 - What material is it made of?

As with any tech product, you don’t want it to break as soon as it falls by accident. You want your new star projector to be made of strong and durable material so that you can use it for many years to come. If you shop online, it can be difficult to know what the device’s outer casing is made of. Pay attention to other customers’ comments to get an idea of how strong the product is.

2 - How bright is the projected image?

The quality of the light bulb installed in the device will have an important influence on the brightness and sharpness of the image. Most quality planetariums will use LED bulbs which are much more advantageous than traditional bulbs: more durable, more powerful and more economical. Some models use a secondary light source: lasers. These are used to display sharp-looking stars across your walls.

3 - How big is the projection surface?

It would be a shame to spend more than $50 on a projector that would only cover half your ceiling. If you are currently looking to buy a home planetarium, I bet it’s because you want to illuminate your home with an out of this world light show. When choosing your future night sky projector, make sure that the light projection covers a large surface area on your ceiling and walls.

4 - What type of power source does it use?

If your home planetarium uses batteries, you will be limited to sporadic use. You will not be able to leave it running at night as a night light because you will have to change the batteries every day. This is not really practical or economical. If it has a USB slot, you’ll be able to plug in a power bank which is really handy.

The way the star projector is powered will strongly dictate how you can use it. If you plan to use your device often, buy a model that uses an AC adapter to plug it into a wall outlet. That way you can use it as much as you want without having to spend a fortune on batteries.

5 - Does it have any extra features?

Some of the handy features you might find on a night sky projector include the ability to play relaxing music or the ability to control the unit with remote control. Prices may vary depending on the type of extra features the projector has. For example, one of the most expensive home planetariums on our list can project 60,000 stars into your room, which is much more than any other model on the market.
