CF Grow CREE CXB3590 High Intensity Full Spectrum Cob Led Grow Light

The CF Grow CREE High Intensity Full Spectrum Grow Light (Buy Online) is one of the best LED lights for a 4×4 grow tent on the market. This 600 Watt light has 6 full spectrum individual COB LED’s. Each one of the 6 COB LED chips can output 120-Watts at peak power.

 

The CF Grow CREE High Intensity Full Spectrum Grow Light uses high-quality glass lenses that will refract light at a 90-degree angle. That will help spread out the light evenly, so you won’t have “hot spots” forming right under the fixture.

 

The full spectrum COB LED chips in this fixture are also more efficient than the regular 3-watt and 5-watt diodes you find in most LED grow lights. That means they will produce more light and less heat, and they will last over 100,000 hours since they are less prone to failure.

 

The CF Grow CREE High Intensity Full Spectrum Grow Light also comes with a dimmer that will let you adjust the light levels. This feature is great if you want to lower the light intensity for seedlings that don’t need as much light shortly after germinating. Then when the plants begin to mature you can turn the dimmer up to full power.

 

Another great thing about this light is that the fans are nearly silent. Even when it is turned up to full power all you will hear is a slight hum when the fans are running. They also barely put out any heat at all, so you won’t have any trouble keeping your tent cool while the lights are on even in the summer.

 

The full spectrum nature of the COB LED’s will also provide a more natural source of light for your plants in all of their growth stages. That makes this light one of the best LED’s for vegetative growth, and it also outputs a lot of light in the red and yellow part of the spectrum that will help promote the growth of dense flowers.

 

Overall the CF Grow CREE High Intensity Full Spectrum Grow Light is a great replacement for an HPS since it outputs a similar spectrum. The fact that it uses CREE bulbs is also a plus since they are a well-known leader in the LED industry. That means you can expect to get many years of service out of this grow light since it is built to last and it’s extremely reliable.

The HIGROW Double Chip LED Grow Light also has a new heat management system. The heat sink on this fixture has been upgraded, and it now uses a thicker aluminum frame to allow for more efficient heat transfer. In addition, the fans move twice as much air as before, and they are still extremely quiet.

This HIGROW Grow Light barely pulls any power when you compare it to a standard High-Pressure Sodium light fixture. In most cases, you can expect to spend 1/3 as much money on electricity. They are also cheaper up front since even the 1000-Watt model will only cost a little more than a hundred dollars.

All in all, I think you will be impressed with the harvests you’ll see if you decide to buy this fixture. It also won’t cost you an arm and a leg, and it will even give more expensive lights a run for their money.

Roleadro 800W COB Full Spectrum Grow Light LED

The Roleadro 800W COB Full Spectrum Grow Light (Buy Online) is one of the most powerful COB LED lights on the market. This fixture has two large LED arrays that each output light with an extremely high PAR value. In addition, it is also more compact than most high-power LED light fixtures.

The Roleadro 800W COB Full Spectrum Grow Light uses two 45mil Epileds LED’s that have a spectrum similar to the CREE CXB 3070. The LED’s are set into a 90-degree reflector that has been specially designed to cover wide areas without sacrificing brightness.

The LED bulbs in this fixture output light that centers on the blue and red parts of the spectrum. The blue LED’s output light between 420nm and 500nm and their peak output is centered at 450nm. While the red LED’s have a spectrum that ranges between 540nm and 780nm, and their peak is centered at 630nm.

This grow light offers a perfect balance of red and blue light for most plants to reach their full potential. The extended red band will also promote denser flowers and a higher yield since it covers a wider spectrum. In addition, the wider bandwidth of the red LED’s more closely mimics the sun, and it gives the light a more natural color.

The Roleadro 800W COB Full Spectrum Grow Light also has a timer built-in to the cord, so you won’t have to purchase one separately to control your light cycle. The timer has a digital display and an on/off indicator. It has 6 settings that will allow you to run the light 3, 6, 9, 12, 15, or 18 hours, which makes it perfect for both vegetative growth and flowering.

This fixture also has excellent thermal properties thanks to the large aluminum heat sink. And each of the COB LED’s has its own fan located right behind it, which helps keep the internal temperature as cool as possible. The combination of both the fan and the sunflower radiator system keeps the temperature of the chips below 118.4 degrees Fahrenheit even during extended operations.

These lights can also be daisy-chained together if you need to run more than one off a single outlet. You can connect up to three of these lights in series, which will provide the equivalent light output of a 2400-watt HID fixture, but in actuality, it will only consume 600-watts of power. Just be sure not to use the cord with the timer if you set them up in this configuration since the timer isn’t rated to handle that amperage.

In our opinion the Roleadro 800W COB Full Spectrum Grow Light offers the best value of any COB LED on the market. If the fixtures with CREE LED’s are outside of your budget, then this fixture offers a similar spectrum at a price that won’t bust your budget. And you can get a few of these and connect them together if you plan on upgrading to a larger tent or grow room later.

Are LED Grow Lights Effective?

Since LED grow lights are relatively new most people are skeptical if they can produce the same results as a high-pressure sodium or a metal halide. While this might have been an issue in the past, modern LED lights are able to emit enough light with a high PAR value to grow almost any type of plant to their full potential.

LED grow lights also emit less heat than HID lamps, so you won’t have to deal with as many heat problems in your tent or grow room. This can save a considerable amount of money in cooling costs, and it can help reduce the risk of heat stress that can cause your plants to suffer.

The most efficient LED grow lights currently on the market are the models that use COB (Chip on Board) LED’s. These high-density LED arrays output more light using a densely packed array of chips, and they use less electricity than the standard old fashioned LED diodes.

That’s why if you want to replace an HID fixture or get similar lighting performance you definitely want to go with a COB LED fixture. The COB LED’s will emit the most light for a given power input, and they will last longer since they have a chip design that is less prone to failure.

 

 

How Many LED Watts for a 4×4 Grow Tent?

(Click to Buy Online)

You will need at least a 600-Watt to 800-Watt LED light fixture for a standard 4×4 grow tent (Buy Online). A 600-Watt COB LED fixture will be more than enough for most 4×4 tents, but if you decide to get a fixture that uses regular 3 to 5-Watt diodes then you might want to go with an 800-Watt model.
