What Are UFO Grow Lights?

Circular Design

The UFO grow light’s shape resembles a flying saucer, hence the name. The circular design effectively and evenly disperses light, ensuring that plants receive ample illumination throughout the entire growing space.

Heat Dissipation Design

UFO plant lights typically feature aluminum casings and heat-dissipation designs such as fans. These designs effectively dissipate heat from the LED chips, extending the lifespan of the fixture.

Selection of Different Wattages and Applications

UFO plant growth lights come in wattages ranging from 100W to 800W. Different wattages are suitable for various applications.

Seedling Stage: Plants in the seedling stage have low light requirements, making UFO plant lights below 100W suitable.

Flowering Stage: Plants in the flowering stage require higher light intensity, making UFO plant lights of 500W and above suitable.

Harvesting Stage: Plants in the harvesting stage have slightly lower light requirements than during flowering, making UFO plant lights in the range of 200W to 500W suitable.

Advantages of UFO Grow Lights

Indoor gardeners prefer it over traditional grow lights due to its advantages.

Outstanding Light Penetration

UFO grow lights utilize high-quality LEDs arranged in a circular pattern, ensuring uniform and efficient light distribution across a wide area. This eliminates common issues like hotspots and light gaps in traditional fixtures.


While the initial purchase price of UFO lights may be slightly higher than some basic grow lights, their energy efficiency and extended lifespan quickly offset costs.

Easy Installation and Use

Most UFO lights come with simple installation hardware and plug-and-play functionality, making them an ideal choice for beginners.

Space Saving

UFO lights are compact and lightweight. Their flat design optimizes space utilization, especially in narrow areas like grow tents or small greenhouses. This makes them an ideal choice for urban gardeners or those with limited space.

Potential Drawbacks of UFO Grow Lights

Limited Coverage Area

The circular design of UFO lights limits their coverage area compared to other types of grow lights such as linear LEDs or panels. This makes them less suitable for larger greenhouses or cultivation areas.

Functional Limitations

Not all UFO grow lights are created equal. While some high-end models offer dimming controls, adjustable spectra, and timers, lower-budget models may lack these advanced functionalities.

Light Spillage and Interference

The disc-shaped design of UFO lights can result in light spillage beyond the intended growth area. This may cause interference in shared living spaces or environments sensitive to excess light.
