Galaxyhydro LED 300w Overview

The Galaxyhydro LED grow light has a professional light proportion that emits 9 bands. It does include red and blue spectra, and the necessary wavelengths in the UV and IR range. The Galaxyhydro wavelengths are designed to provide a quality PAR value, which is shown to be the best way to optimize plant development, growth, and to produce a higher plant yield [Infographic]. The importance of the photosynthetic active radiation (PAR) is a principal element to this grow light because not all of them offer enough light to support adequate PAR values.  But we’re still wondering if it is efficiently built to sustain the needs of an indoor grower.

Our Initial Thoughts

Although almost every LED light technology is relatively expensive, the Galaxyhydro LED is a contender in the realm of inexpensive alternative to the higher priced LED lights. Our Galaxyhydro LED review revolves around the technology based, budget friendly option, but we’re wondering if it can make it through all the phases of growth needed to be considered the best LED grow light for the cost?


Did you know? You will Save Your Electricity and Maintenance Costs. How? Compares to traditional 250/400 watt HPS/MH while consuming only 130 watts. And the heat dissipation speed was increased 20%-30% by the updating cooling fans and heat sinks. Whole LED board will be protected to avoid overheat to ensure stabler use. That means, you can save about 50% energy consumption and get a longer lifespan full spectrum led grow light!

Additional Features for the Galaxyhydro 300w Grow Light


We like the convenience of the dimmable feature. You can easily adjust the light intensity based on your specific needs, rather than having to adjust the height throughout growth cycles. This is a huge plus for growers who like to fine tune their growing process to optimize results.

Full Spectrum LED Light

This full spectrum LED grow light for sale provides a combination of 9 different bands that include both UV and IR. It also includes blue light spectra and red light spectra, with the addition of white light. The light spectrum covers 430 to 730 nanometers, which makes this led light suitable for all stages of plant growth.

300 Watts?

Although the manufacturer states the Galaxyhydro 300w light is rated for 300w, the actual power drawn from the wall is below the rated wattage.  The 300 watts is simply the maximum wattage that the total numbers of diodes are rated. We had higher expectations for this budget grow light and information not complied from Galaxyhydro show that the actual power draw is closer to 170 watts.

Light Spectra

UV 380~400nm, 430~440nm, 450~460nm, 470nm, 610~615nm, 620~630nm, 650~660nm, white light, IR~730nm. Blue and red light spectra support the enhanced PAR value, giving the grower a decent “light recipe” for optimal growth.

Bonus Features: No Maintenance and Excellent Warranty

Much like other LED lights, maintenance is next to nothing. This holds true for the Galaxyhydro as well, making it one of the best features. There are no bulbs or ballasts needed to efficiently maintain this grow light (exp.of 1000W grow light)

Additionally, we were surprised with the 2 year warranty on this panel. The rating is for a 50,000 hour lifespan, which is longer than 2 years. The company makes purchasing the Galaxyhydro LED 300w beneficial to consumers, providing peace of mind to growers. Because other inexpensive LED panels often have a higher rate of failure, the warranty is a huge bonus for us.
