Smart skylight star projector

The Eco4Life SK23 projects thousands of green and blue laser stars alongside a colourful nebula cloud onto ceilings. It is designed for anyone wanting an immersive night-sky atmosphere inside a bedroom or living space. The device operates on a 5V 1A power input and connects via WiFi 2.4 GHz for app and voice control. Buyers who need a projector with 5 GHz WiFi or built-in Bluetooth audio streaming should look elsewhere.

Thermals noise and power

The projector runs on less than 1 mW per laser beamlet with Class 1 laser classification for safe everyday use. Its V0 flame-retardant ABS shell handles operating temperatures from 14°F to 95°F (-10°C to 40°C) without active cooling fans. Power draw stays minimal at the 5V 1A input, so the unit adds negligible heat to the room. Users who require completely silent operation will appreciate the fanless design.

Build and daily connectivity

The shell uses V0 flame-retardant ABS for durability and safety. A single physical button on the unit provides basic on/off and pattern switching without a phone. The WiFi 2.4 GHz link pairs with the Eco4Life app for scene creation, colour selection, and mode choices such as Static, Jump, Gradient, Breathe, and Flash. Voice control works with Alexa, Google Assistant, and Siri through the same 2.4 GHz network. Households without a 2.4 GHz band cannot use the smart features.

Questions about this item

How do I mount the Eco4Life SK23 and which step is often missed?

Place the projector on a flat surface or use the base to angle it toward the ceiling, then connect the 5V 1A USB power supply before pairing it to your 2.4 GHz WiFi network; the step most people skip is confirming the router is set to 2.4 GHz only.

What maintenance will the Eco4Life SK23 need over time?

The Class 1 laser diodes (green 515-520 nm, blue 450 nm) and LED nebula engine are sealed and rated for continuous use, so only occasional dusting of the lens and vent openings is required; no user-replaceable parts are specified.

What is the first limit I will hit if I run the Eco4Life SK23 all night?

The operating temperature range tops out at 95 °F (40 °C); if the room exceeds that, the projector will shut down to protect the laser and electronics.
