Testimonials

"This grow lamp offers a very high brightness that will delight demanding plants. The supplied mounting accessories allows the lamp to be installed in different ways.

The whole light is very quiet thanks in particular to the absence of fans.

In my closed greenhouse with the lighting on for 12 hours continuously, the temperature does not exceed 25º.

What makes me most convenient is the dimmer. With a dimmer that can be adjusted from 1% to 100%, I don’t need to adjust the height of the light according to the different growth stages of the plant!

Very fast delivery in a super well packaged and very well protected from shocks.

I recommend this lamp."

"Bought these New lights & they are the real deal!

First of all, the package is excellent. No way that these light could be damaged during the delivery.

Secondly, this photo is not enough to show that the actual brightness and output of these lights are amazing!

I bought 5 of the 6000w & will add 1+ more soon! 

The light spectrum coming off the unit is very bright but still easy on the eyes.

I know my plants will appreciate that a bunch.

The connector should definitely be tight against sweat and splash water.

Overall, I was surprised by these grow lights."

"Product arrived promptly within 5 days, very well packaged. Solid fixture has a quality feel to it. The spectrum is great but not stimulating to my eyes. I have the light hung 12" above canopy in the 3rd week of bloom.

The light has a good intensity, wide spread, and nice canopy penetration. Works great to flower a 4x4 area.

Growstar did a wonderful job with the heat sink style. All the switches and dimmer control feel nice and smooth operation as well. I would highly recommend this light if you have a 4x4 space or something larger where multiple matching lights can be used with the daisy chain feature!

BEST GROWSTAR PRODUCT YET!!!

Time will tell and their LED's haven't let me down yet! THANKS GROWSTAR!!"

LED Grow Light Information

LED Grow Light Information

Even if you live in a temperate region, grow lights help you stimulate indoor plant growth by allowing more photosynthesis. During the winter season, grow lights offer you increased control over your plants' light exposure. These lights, especially those powered by light-emitting diodes, or LEDs, cater to grow trays and hydroponic systems as well as greenhouse environments. While LEDs don't use the same amount of energy as other grow lights, they do offer some benefits, especially in terms of efficiency.

Growing Plants With LEDs vs. Other Light Sources

Thanks to their energy efficiency and long useful life span, light-emitting diodes are an attractive option for use in indoor plant-growing contexts as compared with less efficient lighting technologies. LED grow light technology is in its infancy, however, and some of the potential advantages of LEDs for plant propagation have yet to be fully realized.

For ideal plant growth, nothing beats natural sunlight. Grow lights fall short of the sun's perfection, but they compensate for short days and low light indoors. Light-emitting diode (LED) lights take grow light technology into new dimensions. Instead of trying to replicate the sun, they target the quality of light plants need most. The wide-reaching results affect everything from space travel and greenhouse growing to home gardeners starting early seeds.
