Best (TOP) 600W Grow Light Review

The principal reason growers chose LEDs over conventional lighting is due to the electricity savings. LED grow lights consume fewer watts to produce roughly the same amount of usable light as HID bulbs. This is one of the chief benefits of growing with LEDs. A grower may use LEDs to deliver more PAR for their plants per watt of power.

Bear in mind that a number of the wattage the fixtures draw isn't all converted into light. Some of the energy is lost as heat. Moreover, additional wattage could be used to power cooling fans that blow off radiant heat away from the heat sinks.

As soon as you've determined whether LED grow lights are ideal for you, it is time to figure your particular lighting needs in order to budget for your new grow room. Don't worry if this sounds daunting. We have you covered with this post about calculating your lighting and insulation needs And before you begin growing, take a look at our four-part series on the best way best to build your own grow room Need more information on the most essential topics?

The typical efficient LED grow light brings about 32 watts to cover one sq feet of grow space for flowering plants. Compare this to a normal HID fixture that will ring in at 62.5 watts per square foot (assuming a 4' x 4' area, or 16 sq ft coverage area).

Benefits Of Utilizing LED light

Grow lamps used to be enormous and ungainly -- fluorescent tubes over a metre long that required complicated and hideous systems of racks, cables and reflectors all coming at a substantial price. They consumed plenty of energy too, so not great for the entire world, or your electricity bills. They also emitted quite lots of heat, increasing safety problems and damaging the plants which were being grown.

Lower HVAC prices

Since growers have the ability to use fewer watts to provide the same quantity of light to their crops, they will have lower capital and operating HVAC costs. Larger grow rooms will need less air conditioning to cool the space. Growers have reported a decrease of 50 percent in ac costs when switching to LEDs. Does the A/C reduction stem from the efficient lighting technologies of LEDs, but the fact that growers can conduct their grow room temperatures up to 10° F warmer when using LED grow lights.

Smaller grows may consider removing air conditioning from their grow setups entirely, because it could be possible to get ideal grow temperatures with just using the heat given off from the LEDs grow fixtures.

Additional growers might consider reducing the energy required to run ventilation into and throughout their grow regions because ambient temperatures are reduced when using LED grow lights. This is supposing ventilation is used to cool the grow area as well as providing adequate air flow. A higher rate of air flow can help out with keeping ambient temperatures cooler if the intake air is cooler than the air inside the grow surroundings.


Light emitting diodes are around 40%-60% more effective at converting energy to usable light in comparison with HID lights. The high-efficiency feature of LEDs enables lower energy draw and a very low heat signature. LEDs convert about 40%-60%+ of the energy to light, while the additional energy is given off as heat. HID bulbs only convert just about 20%-40% of the energy to usable light. What does this mean to the grower? Fewer watts are required to create the identical amount of light as conventional grow lamps.

Another way to consider efficacy is via PAR efficacy that is typically reported in μ mol/J (micromol per Joule). PAR efficiency is more important than using electrical watts to compare grow lights, since a fixture may draw a good deal of watts, but that wattage won't directly translate to high usable light. Using wattage to find out the quantity of usable light and growing region is a relic from the times of HID.

Why does efficiency matter more than wattage? Consider two fittings that cost exactly the exact same sum of money per watt. Fixture'costs $1500, draws 500 watts and emits a typical PPF of 700 μ mol/s. Fixture B costs $2000, draws 666 watts, and emits a typical PPF of 500 μ mol/s. An individual can already begin to see the issue more money has been spent on Fixture B that draws more watts and doesn't emit as much usable light as Fixture A. The efficacy of Fixture A is 1.4 μ mol/J (1 watt = 1 Joule), while the efficacy of Fixture B is just 0.75 μ mol/J. Conclusion: Fixture A costs 25 percent less than Fixture B, emits 28 percent more light, and is 46 percent more efficient. With an LED grow light with higher PAR efficiency will save money on energy prices.


High-pressure sodium and metal halide bulbs contain mercury and release toxic vapors upon breaking. These bulbs require safe disposal to make sure they don't Leach carcinogens to the environment.

On the other hand, LEDs do not contain mercury and are deemed safe. This is largely true they don't contain mercury, but they're not completely metal-free. A 2010 study from the University of California Irvine, found very-high levels of lead in low-intensity red LEDs and elevated levels of copper, nickel, and silver in different colors of LEDs, except for in low-intensity yellow. LEDs are solid state lighting and the diodes are generally very small so don't risk breaking. Yet, if the diodes end up in the environment and break down, the compounds can Leach.

Extended Lifetime

Most LED grow lights in the marketplace contain LEDs that will last around 50,000 hours. Some producers use LEDs that last up to 100,000 hours or more. This is equal to nearly 10 years of use (at 50,000 hours) or nearly 20 years of use (in 100,000 hours), respectively. Compare this to MH bulbs that last an average of 10,000 hours or HPS bulbs that have a lifespan of 16,000 hours or so.

Because of most LED panel's modular build, if a grower still had the LED light at the end of its lifespan, then they might have the ability to swap out the old LEDs for new ones and continue growing.

Full Spectrum

The best LED plant lights generate a balanced full spectrum of light. As stated previously, they give you all of the light your plants need and nothing more. Do not go for the"blurple" lights. The notion that plants need only blue and red light is outdated.

Plus, most fixtures permit you to turn off specific wavelengths, which means it's possible to produce the ideal light for each phase of plant growth. It follows that LED lights are in fact better for your plants than normal light.

  • Setting Up an Indoor Plant Growing Area

    How can you get enough light for houseplants and indoor garden areas? Here are three tips on how to best set up your space.

    Consider your indoor garden plot. Whether it is a single shelf, a basement area, or an entire room, look at how much space you have. Pot plants and wedding accordingly.

    Based on the type of plant, set the baskets or trays 4 to 8 inches apart to allow for growth and effortless accessibility for pruning and care.

    You will also want to make sure you buy lights that will illuminate your whole plantings area. You will need more than 1 bulb or light source to completely cover your growing region. Based upon the size, you might just have to use just 1 light for houseplants, or perhaps you need more, sprouts flourish under a nurturing lighted environment.

    Final Words

    It's nearly sure to determine that LEDs are nearly a MUST use when you decide to grow indoor, secure and developed in a manner which makes harming plants very hard, it's not impossible. Because of the info above, it's the ideal decision to receive your own.
