Patented COB System

With a patented onboard chip system in place, the Roleadro 400-Watt COB grow light brings in more centralized light sources for the plants.

Roleadro offers detailed explanations on how to best use the Daisy chain system for maximum yield from the plants. This nifty feature does open new doors on the usage of COBs.

Full Spectrum System

Standing on the back of its 2nd generation model, the Roleadro COB grow light (400 W) drastically improves the color uniformity and PAR value.

Providing a full spectrum to ensure all the plant requirements are satisfied, the Roleadro COB comprises a blend of 440 nm, 460 nm, 470 nm, 525 nm, 610 nm, 630 nm, 640 nm, 660 nm, and 730 nm wavelengths.

Apart from the 400-Watt model, you can also go for the 800-Watt model if you have a bigger grow room or you want better light. They also make a 200W model, if you have a smaller grow, or require less light.

All of the above models are a good value for the money, and have received a good response from customers.

Efficient Heat Dissipation

With a dual fan system running the Roleadro 400 Watt COB system, the heat produced is easily negated. Capable of running for up to 18 hours a day, the efficient dissipation system ensures the longevity of the product. The fans run almost noiselessly so disturbance from the sound shouldn’t be a problem, to say the least.

Full spectrum LEDs do not produce much heat when compared to standard HID lights. The COB lights are super power efficient as well, and run cooler than the conventional lamps. Yyou can expect a cooler environment when using the Roleadro COB LED grow light.

Patented Reflective Cups

Native to the Roleadro 400 Watt grow light are its patented reflective cups. With a 90° coverage area, the reflective design ensures a maximized output with fully blended light. The losses are drastically reduced, thus improving the efficiency of the device. The plants get the adequate light which results in a better quality product in the end.

2-Year Warranty

With current LED lights being susceptible to frequent failures, the 2-year warranty comes as a welcome boost for consumers. Roleadro also provides a 30-day exchange policy if the product you received doesn’t meet your standards.

The Roleadro 400 Watt COB grow light has all the necessary features you’d expect from a standard COB system. Yet, there’s more! Catch some of the additional features this product has to offer:

High Quality Epileds

With high-quality epileds integrated with the COB system, color uniformity and the luminous efficiency of the system is enhanced.

This ensures that the rays from the 400 Watt COB grow light are better absorbed by the plant, which in turn radically improves the output and the growth rate.

Sunflower Radiator System

With the Sunflower arrangement of a radiator system in place, the Roleadro COB grow light (400W) reduces the temperature at the base of the chips to below 118.4°F. A lower temperatures mean longer switch-on time for the device without any harm.

Modular Light Design

The Roleadro COB LED grow light is quite famous for its design. It has got separate chips onboard which ensures the quality of the grow light. If one chip is damaged, the others are capable of running independently without their damaged counterpart.

Galaxyhydro 300W LED Grow Light Review

Let’s put the product through its paces and see what the Roleadro Galaxyhydro LED plant grow light, full spectrum 2nd generation series brings to the table.

The 300 Watt Debate

Although texts claim that the Roleadro LED grow light draws 300 Watts, the actual power drawn is more in the vicinity of 130-150 Watts. The technological advances try to make up for the lack of drawn power with brighter and better lights.

High Proportion Red Lights

Red light is the ideal spectrum for photosynthesis, the 300 Watt Roleadro grow light incorporates a lot of it.

With a large proportion of the lights dedicated to the red spectrum, Roleadro Galaxyhydro claims that indoor plants can receive 12-18 hours of ideal lighting time with a standard 26-28f temperature throughout the year.

Full Spectrum Light System

Standing on the back of its 2nd generation model, the Roleadro grow light claims to have stitched a wide and sufficient light spectrum into the product.

Covering 9 different bands including the UV & IR the Galaxyhydro contains an 8:1 Red-Blue system with 2 white LEDs.

Epileds 45 mil LED Chips

LED lights save tons of energy without dissipating a lot of heat. Equipped with the Epileds 45 mil LED chips, a significantly larger amount of light is available for the plants.

With strategically placed LEDs oriented at a 120° angle, the resemblance to solar rays (PAR) increases. Not just that, the canopy penetration goes up as well. This further strengthens the plant down to its roots, ensuring you get a better yield in the end.

CE & ROHS Certified

Designed with advanced technology, the product comes with better lights, draws lesser power, achieves better-targeted growth of the plant while causing minimal heating of the surroundings, thanks to its improved heat dissipation system.

2-Year Warranty

With current LED light’s affinity for frequent failures, the 2-year warranty comes as a welcome boost for consumers.

If the feature-rich Roleadro Galaxyhydro LED grow light hasn’t got you hooked, here are a few more useful features!

Dual Cooling Fans

Keeping the 300 Watt Galaxyhydro cool are two cooling fans running in the background.

This lower heat dissipation lets the Roleadro Galaxyhydro grow light get closer to the plant. This makes it particularly adept at handling indoor conditions.

Dimming Light Feature

Another feature in the device is the ability to dim the intensity of the light.

Users who know the nuances of plant growth can fiddle with the intensity for the ideal results. This nifty feature is a nice touch from Roleadro. This feature particularly helps in modulating the intensity of light during different plant growth stages.

Zeners Exit

Speaking of nice touches, the use of the Zener’s Exit function ascertains the build quality of the device.

Ensuring that the rest of the LED remain working if one of them fails, the product doesn’t skimp on the manufacturing despite the low cost.

Low Maintenance

LED lights have an inherent advantage as they require far less maintenance in its handling. Rated for 50,000 hours, the Galaxyhydro should outlast its 2 year warranty period with ease.

With all the offerings spread out, the Roleadro Galaxyhydro LED Plant Grow Light does seem to have a lot on its plate. Yet, are there any shortcomings, you ask?

Let’s list the pros and cons to evaluate:

  • Low price, feature rich 300 Watt LED grow light with a 2 year warranty.
  • Full Spectrum 9 band system with UV and IR, additional dimming feature.
  • Uses less power, hence saves energy and money. Maintenance charges close to zero.
  • Light weight (~8 pounds) and durable with low heat dissipation making it ideal for indoor growers.
  • Good build quality combined with a tried and tested approach for the optimum light recipe for plant growth.
  • Better options available for a higher budget.
  • No provision for manually controlling the spectrum.

The pros of the 300 Watt Galaxyhydro grow light far outweigh the cons. So unless you’re especially nitpicky about the spectrum of light hitting your beloved flora, we’d say the Galaxyhydro is a fine investment for your indoor growing needs.

Getting a full spectrum light for such an affordable price truly states the technological advances that have enabled the company to manufacture such a great quality product.

If you have a bigger budget, you can opt for 600w LED grow lights. You can also accumulate more grow lights in your grow room if you feel that the 300-watt is not sufficient.
