Picks of UFO LED Grow Lights

1. Growstar UFO LED Grow Light

Best UFO LED Grow Lights

Growstar UFO LED is one of the most popular grow light options among growers. This full-spectrum lamp encompasses wavelengths from 380 to 760 nanometers, including the UV and IR lights. All together provide your cultivars a more complete and advanced spectral output.

This 150-watt UFO lamp comes with a 3000K color temperature. Its warm white light is applicable for vegetables and flowers in all stages of growth. Thus, it is more convenient to use as you no longer need to switch to different grow lights as the plant matures. 

But the biggest advantage of using Growstar UFO LEDs is its CREE LED chips. This allows the bulb to have a high CRI rating of 90. Such a figure will tell you how close the actual color display is in real-life applications. The higher the rating, the more likely you will get an accurate color temperature.

Moreover, this CREE LED is strategically set in a 90 to 120-degree angle. This positioning helps to increase the brightness and widens your light footprint. In effect, it further optimizes your output for better efficiency.

Growstar UFO LED also comes with a cooling fan system for ventilating heat. It consists of a built-in aluminum heat sink and aircraft-grade aluminum casing. Both structures effectively dispel the radiated heat created by the lamps. Thus, helping to maintain the coolness of your system at all times. 

Things to concern:

Growstar UFO LED is bright and affordable grow light. Although, some of its customers were not quite pleased with its longevity. Others complained that the bulbs burned out way too quickly that it should be.

Mrhua UFO lamp also comes with 3000K color temperature. This warm white lighting is suitable to use across all stages. But, it’s good amount of blue and yellow hues also make it a great option for plant’s vegetative growth.

In general, this 150-watt UFO LED can cover a 1.5×1.5 up to 2×2 grow space size at a 24-inch height. This can still vary though depending on the current growth stage of the plant. 

Mrhua LED grow lights are also well-built. It comes with a Zener diode that helps to protect each of the LEDs. So, when one unit is being damaged, it won’t take a toll on the rest of the LED bulbs.

Furthermore, the grow light provides an effective cooling fan system to dissipate heat. The fixture is being integrated with a built-in ball-bearing fan and aluminum plates. Both aid in keeping the grow light cool by drawing out the radiated heat by the lamp.

3. G8LED Red Flower Booster LED Grow Light

G8LED Red Flower Booster LED Grow Light

G8LED Flower Booster UFO LED is a bloom only grow light. That means the lamp full-on consists of red spectrum lights from 630 to 660 nanometers. Thus, making it perfect to use during the flowering cycle of the cultivars.

This flower booster LED delivers a PAR value of  770 µmols/m2/s at a distance of 12 inches from the plant canopy. This flux is effective at increasing the size and density of your flowers. Thus, in a way increasing the quantity of your harvest as well.

Because this UFO LED only contains red lights, it works best as a supplementary light. You can opt to pair this lamp to either a full-spectrum LED, CFL, or HID systems. Doing so will provide your cultivar a more holistic support.

During the blooming phase, you can add one flower booster UFO LED lamp for every 8 to 10 square feet of grow space. That is approximately the size of a 3×3 grow tent or room. Add more as the area coverage increases. Results are likely to show after a week or so of exposure to red lights.

Things to concern:

G8LED Flower Booster is being designed to deliver just the red spectrum of lights. That means, its function is only limited to the flowering cycle of the cultivars. So, you may still have to provide your plants with other types of grow lights to sustain their needs for the rest of the stages.

Magic Line:

The perfect UFO LED for boosting the blooming cycles.

Things to consider when buying UFO LED grow lights

  • Light Spectrum

The majority of growers prefer to stick to UFO LEDs that provide the most range of the light spectrum. The more complete the wavelengths, the better! 

Full-spectrum grow lights are very versatile. They can well-support the needs of plants at any stage of growth. 

There are also some UFO grow lights that are more light-specific. Such types of lamps may either contain red lights for flowering, or blue lights for vegging. Because of its limitations in spectral output, they are best used as a supplementary light instead. 

  • Heat Management

Grow lights are the number one contributor of heat in every grow space. Thus, you would want to choose for a UFO LED that comes with an effective cooling system. This may include high-speed fans, aluminum heat sinks, vents, and others.

Heat management is very important for indoor gardens. Not only will it affect the lamp’s performance, but it will also bring all sorts of problems to your plants. So, make sure to consider this factor when buying UFO LEDs.

  • Energy consumption

LED lamps are best known to consume less energy than other conventional lamps. But, not all LED lamps are being created equal. Some bulbs might declare a low-wattage right off the box, but end up consuming more in actual.

So, take the time to do your research and see which products live up to their claims. If you already have them on hand, it is good as well to keep track of its actual power draw. This is one of the surest ways to check if the UFO LED you have chosen is truly energy-efficient.

  • Longevity

LEDs are one of the most long-lasting grow lights in the market. A UFO LED lamp has an average lifespan of 50,000 up to 100,000 under the right conditions. That is equivalent to about 5.7 to 11.4 in years. 

That is such a longgg period of time!

Although, there are a lot of factors that can affect the bulb’s longevity too. External elements such as thermal and electrical stresses can negatively impact its integrity. Thus, increasing the chances of further shortening the lifetime.

  • Cost

Okay, this one is very subjective!

Cost may or may not be a deal-breaker for a grower. What’s affordable for you, may not be for some. In that regard, we will not mention any amount here.

What is important is that you should be able to determine your budget for UFO LED grow lights. Set a workable range of price points. From there, you can narrow down your options to what is only available for that given amount.

Although, it is good to note as well that expensive pricing doesn’t necessarily equate as the best product. We often used to think that good quality items come with premium prices. That may be true in yesteryears, but that’s no longer the case nowadays. 

That is due to the fact that we have wider access to resources and technology at this period in time. Thus, it makes it easier for manufacturers to produce items that have competitive quality but at a lower price point. 

So, just because it’s affordable, it doesn’t mean it is already cheaply made!

In that sense, try to look beyond what the price tag and marketing tells you. Rather, look into the quality itself of the grow light. Be it affordable or expensive, make sure to opt for UFO LEDs that give you the most value for your money.

Wrapping Up:

If you are looking for compact but effective grow lights, UFO LED is the way to go! These lamps give you the same level of energy-efficiency as regular LEDs. But, their circular design enables optimization of light without the need for bulky reflector hoods. 

The five UFO LEDs we presented herein are some of the best products you can find in Amazon. They are already tested by newbies and seasoned growers. So regardless of your level of expertise, you are sure to find one that would suit you and your grow room best.
