Expertly designed to deliver an astounding 2.8µmol/J and 2016 µmol/s PPF using top-quality OSRAM and Sanan LED chips, the GJ720 720w LED  offers powerful full-spectrum light across eight LED bars.


The GJ660 LED grow light offers the grower insane returns on their investment. It is a linear multi-light bar fixture producing high PPF of 1716 µmol/s and a Photon Efficacy (fixture efficiency) of 2.6 µmol/J.


The GJ880 is an exciting new addition to the GJ LED grow lights. These fixtures boast a full spectrum of light with a fixture efficiency of 2.7 μmol/J and total output (PPF) of 2160 μmol/s.


Our Goal

At Grower’s Joy, we pride ourselves on being able to deliver the best possible supplemental grow lighting for every customer and application. We work hard to be innovative and come up with new ways to improve our products so that growers can get the most out of their yields.

Why Use an LED Grow Light?

LED grow lights have gained popularity amongst growers in recent years for their energy efficiency, low heat output, and ease of use. Since the technology has developed so much over the last few years, if you’ve tried LEDs before but was not satisfied, now is the perfect time to give them another try.

Complete LED Lighting System

Those who are looking for significant returns on investment and the highest quality lighting systems are now turning to LEDs to accomplish their goals. We offer a balance of light quality and light quantity which will supply your crop with everything it needs throughout the entire growing cycle, from the vegetative stage through to flowering, with only one lighting fixture.

PAR Testing

The amount of photons in the PAR wavelengths is known as the Photosynthetic Photon Flux (PPF). Measuring a light fixture’s PPF instead of its watts or any other unit is a more accurate way of determining the light’s true “size.”

Light Intensity & Yields

Wageninen University did a study that found that yield goes up by 1% for every 1% increase in light. This applied to all horticultural crops, including fruiting crops and flowers.

Wholesale Shipping

GJ is working on improving the shipping speed experience by gradually sending fixtures to stock in the USA warehouse. By arranging delivery of the products directly from our stock in our cooperation warehouse in USA, we will greatly shorten the shipping time .

LED Grow Lights Aging Test

The aging test of LED Grow Lights helps identify conditions that can affect the use of the product. By testing the product in these simulated conditions, it can help ensure that it will stand up daily use. Testing can lead to an improvement in the product’s design and increase its durability.

Once the LED grow lights have finished production, it’s important to test them before they leave the factory. This helps to make sure that any common problems like short-term high voltage or light shut-off will be detected and fixed. Our goal with this testing is to be certain that the power configuration is qualified, the welding position is firm, and the assembly wire is reliable.

LED grow lights are one of the most energy-efficient and long-lasting options available when it comes to grow lights. To ensure that your LED grow light lasts as long as possible, it’s important to make sure that the power quality is excellent. Additionally, most LED grow lights come with an automatic overvoltage power-off device that protects the light from damage.
