G8LED-900W MEGA LED Grow Light review: Basic info about the product

This grow light is built to provide you with everything in abundance. You take the PAR value, coverage area, HPS replacing capability, etc. But at the same time, the price is as high, due to which a big number of buyers hesitate in buying it, and hence, it didn’t get the proper attraction, when launched in the market.

This grow light was awarded as the best indoor grow light of your 2016 by High Times Magazine. That means a lot! This is one of the biggest energy savers, among the 900W models highly bright, and high durability. We will reveal info about this product one by one, and right now, let us start with the features.


Wikipedia called it the best indoor grow light of the year 2018, and one of the main reasons behind that is its abundant features. Let us see what all this grow light offers you regarding features.

3W LED used for better penetration

Makers of this grow light have concentrated hard on the penetration fact. That is a reason for which they have used 3W LED chips, instead of 5W or 10W, which are more powerful and bright. As a result, the penetration of this grow light is up to 60 inches from the canopy, and that is the factor responsible for making it one of the best grow light for thicker vegetation.

These LED are all manufactured by the top trending company, and you do not need to worry about its durability.

Spectrum with 8 bands of lights

The makers of this grow light claim that they would have made a 15-20 band light, but anything stretched above eight bands of light is entire wastage of light. You are getting a full spectrum with G8 LED 900W grow light, that consists of a perfect blend of red, blue, IR and UV. With this full spectrum, your weed and cannabis grow denser, better, and have a better aroma. But we cannot deny from the fact that with this grow light; you are not getting the full spectrum.

The makers claim that this grow light is capable of providing you with the highest yield per unit of energy consumed.

The perfect heat dissipation system

The success of a grow light heavily depends upon how efficiently the heat dissipation system that grow light works. Just a little bit of extra heat and your plants are gone! When we have a look at the working of the heat dissipation system of G8 LED 900W Mega grow light, we feel as if the makers have taken more time for the construction of this system, in comparison to the whole grow light. It is perfect.

The fans, as well as the heat sinks, work cent percent perfectly, to perpetuate the right temperature inside the grow tent. They never let the temperature cross a certain limit, and keep the grow tent cool.

Decent PAR value

It seems as if it is the only grow light in the market, that gives a tough competition to the advance platinum series grow lights, regarding the PAR value. At 16 inches, the PAR value you get is 1540 umols. That is the second best PAR value when we talk about the 900W models in the market.

One of the biggest advantages of high canopy penetration and high PAR value is that you can grow comparatively more plants in less space, as the density is not going to stop this light from providing equal light to all parts of your plants.

Actual power draw and HPS replacing capability

This grow light deeply satisfies you with the actual power draw. 540W is what it is going to suck from the wall, and it also remains just half, if you are running your grow light on the Veg mode. So, you are not going to notice a significant hike in your electricity bills.

While the actual power draw is just 540W, G8LED-900W MEGA LED Grow Light is capable of replacing a 1000W-1200W traditional HPS light system. That impressed really much. Remember, your yield very much depends upon the power of a grow light, and this power is determined by two major factors. One is the PAR value, and the other thing is HPS replacing capability. Both the things are too good in this grow light!

Wide coverage area

The wide coverage area that it provides you is a big reason for which this grow light is high in recommendations for the advanced level and large-scale growers. Want the numbers? Well, 24 square feet is what you are covering maximum with this grow light. It is a decent choice for a 5′ x 5′ grow tent. This grow light is among a very few, which offer you such big coverage area.

90W red Flower boosters

These switches play a vital role in the process of providing you with the best yield possible. But these are not present in this grow light. 90W Red Flower Boosters are added to boost up the total ratio of red wavelengths, and besides that, more wattage is added to the growing area to receive the max yield possible.

The company says that by using veg/bloom switches, you turn certain lights off, and that is not the best way to grow! They say you must provide all lights, without cutting any of them off.

The warranty

Honestly, we do not get much satisfied with the warranty period. You are getting just a couple of years of warranty. Usually, you get a 3 years warranty, from the dominating grow light manufacturing companies and some like advanced LED provide with a 5 years warranty. But the thing that matters is how responsive the warranty service is. With G8LED, the users are very happy with the customer service and short process of the warranty claim.

You are getting a triple period of money back guarantee. Normally you get 30 days, but with this grow light, you get 90 days.

It depends upon the growth stage and what plant you are growing. Most importantly, this Grow light very bright and powerful, so do not hang it too close. Normally, hang it somewhere between 26-42 inches. 42 inches is for taller plants.

Sorry, you do not get that option with this grow light. You are getting extra wide grow area though, but no daisy chaining feature. Pretty unexpected!

The power cord comes according to the voltage of the country, from where you have ordered it.
