The Best Full Spectrum LED Light

Bestva Grow lights Review

Bestva’s DC Series 3,000-watt full-spectrum LED grow lights enable you to tailor your light settings to your target plant growth stage.

The onboard “Bloom” switch boasts carefully calibrated settings for seedlings and flowering stages. Meanwhile, the “Veg” switch is set for growing and fruiting. You can also turn on both switches at the same time to maximize your light’s power output. This is important because plants require different light spectrums at different growth stages.

Energy Efficiency

While the light is advertised as a 3,000-watt unit, it only uses about 540 watts to produce the equivalent level of full-spectrum light. This amounts to an energy savings of nearly 80%. You can expect your electricity bill to be much lower than it would be compared to most other lamps in the same power range.

The Bestva utilizes dual-chip 10-watt LEDs. Customers will tell you that these are far brighter and more reliable than the single-chip alternatives.

Coverage

The rectangular unit contains 231 individual lights. It measures 12.5-by-8.8-by-2.8 inches and weighs approximately 10 pounds. The light offers 4-by-3.5 feet of coverage in the “Veg” stage and 3-by-2.5 feet of coverage in the “Bloom” stage. Lights should be placed at a height of roughly 24 inches so that the rays can be evenly distributed across an 8-by-7.8-inch growing surface.

The blue and red lights are equally powerful. As such, the combination is a close comparison to natural sunlight.

Despite the light’s nominal power draw and heat production, you are guaranteed an impressive PAR.

Cooling

Each lamp is equipped with a powerful cooling system. The units use 3-millimeter aluminum plate radiators for better heat dissipation. Meanwhile, holes in the glass and aluminum surfaces help excess heat escape.

Thanks to these design elements and built-in fans, the unit operates 50 to 60 degrees lower than most other LEDs. At least, that’s what the manufacturer purports.

You can trust your plants will not have to endure any unexpected temperature spikes during their growing. This unit rarely heats up above 100 degrees Fahrenheit.

How to Choose the Best Full-Spectrum Grow Lights?

Purchasing grow lights is not always a walk in the park. If you want more information on growth light specifications, you’ve come to the right place. The following buying guide covers everything you need to know before you set out to find grow lights for your operation.

Light Strength

Before you can begin shopping, you will need to know your target growth light intensity.

Consider the Light’s PPF Rating

The PPF, or photosynthetic photon flux, is the number of light photons that are produced by a light fixture each second. PPF is measured using a PAR, or photosynthetic active radiation, meter. The measurement is then expressed in umols per square meter per second. An ideal PPF rating ranges from 400 to 700 nanometers.

Check the PAR Findings

PAR, or photosynthetic active radiation, is the wavelength of light within the visible range. This figure starts at 400 nanometers and ends at 700 nanometers. Your target PAR depends on the type of plants you are growing as well as the distance of your lights from your plants.

Common vegetables, including tomatoes and lettuce, require 400 to 500 umols/m2/sec. Meanwhile, the recommended PAR level for marijuana is 300 to 400 umols/m2/sec.

Few plants require more than 1,000 µmols/m2/sec of PAR. In most cases, a light that offers 500 to 1,000 umols should be sufficient. You can usually get away with lower PAR ranges during early growth stages. Meanwhile, more powerful PAR ranges are needed during flower and fruiting.

Analyze the PPFD

PPFD, or photosynthetic photon flux, is a unit of measurement used to describe light intensity in a specific area. Or, in other words, it is the amount of light that falls on the PAR region of your growing area every second. As we already know, plants need 500 to 1,000 umols of PAR per square foot per second.

PPFD is sometimes confused with PPF. However, PPFD is the amount of light that actually impacts plants. Whereas, PPF is the amount of light produced by a fixture.

Spectrum

Light spectrum is yet another key factor concept that you need to understand before you select the right grow light. A qualifying light needs to offer a full spectrum of light colors to promote photosynthesis (chlorophyll absorption). Most growing experts recommend a full-spectrum fixture that offers a ratio of blue and red light as well as some UB and far-right radiation (photomorphogenesis. This spectrum usually covers the full photosynthetically active radiation range (PAR) or 400 to 700 nanometers.

Virtually every stage of the plant life cycle is dependent on targeted light wavelengths. This includes fruiting potential, flowering yield, vegetation growth, root growth, harvest characteristics, and harvest yield.

Blue light, which also falls within the 100 to 400-nanometer range, can determine the vegetation development, root development, and flower development of plants grown indoors. Meanwhile, red light (600 to 700 nanometers) improves plants’ photosynthesis and biomass. The UV wavelength, which ranges from 100 to 400 nanometers, is responsible for flavor and photosynthesis.

Most plants come with a recommended blue to red ratio. For example, lettuce fairs best with a 35:65 blue to red ratio. Meanwhile, tomatoes turn out best when they are exposed to a 5:1 ratio of red and blue.

Some growers think of light spectrum ratios as an element of plant design. When you understand the impact of light spectrum ratios on your plants, you can easily make changes to determine the outcome of your harvests.

Wattage

While you might be eager to save a buck on your electricity bill, LED lights with low electricity consumption are not always as promising as they appear. Oftentimes the lower power equates to lower production. If your fixture isn’t capable of producing enough PPFD, then it’s not going to help grow plants efficiently.

Most growers like to have a good idea of how many watts of electricity they’re using per square foot of grow space. This helps them to calculate their overall electricity expenditure. A draw of 20 to 50 watts per square foot is standard. You can use this calculator to determine how many watts of power your lights will use per square foot.

Understand Driver/Chip Compatibility

LED grow lights consist of corresponding chips and light-emitting diodes (LEDs). The chips transmit messages, such as light settings and timer settings. When these elements synchronously, growers can alter their lights’ PAR spectrum to better suit each plant growth stage.

Coverage

Another essential consideration is growing space coverage. You need to be able to calculate the amount of growing space that your fixture can support. This number varies from grower to grower. After all, some people are managing large warehouses, while others boast 4-by-4 grow tents.

Generally speaking, lights with higher wattages are capable of covering larger areas. You will need to consider a light’s wattage, coverage area, and distance from plants before you can determine how many lights you need for your growing space.

Take into account that you may need to raise or lower your lights during different growing spaces. Raising and lowering plants alters a light’s overall PAR per square foot.

Cooling

While LED grows lights do not get nearly as hot as traditional light fixtures, they still produce excess heat. Most lights have a combination of onboard heat sinks, radiators, and fans that help them to maintain a reasonable temperature.

Without a reliable grow system, you risk exposing your plants to excess heat and dryness. The heat that is produced by LEDs has nowhere to go inside a grow room or tent. As such, it is automatically absorbed by the plants and other objects in a growing area. Grow rooms should be well ventilated. The temperature inside the room should fall somewhere between 70 and 85 degrees Fahrenheit when the lights are on.

You can calculate a grow light’s estimated heat production by multiplying the number of watts used by 3.41. This gives you the fixture’s heat production in BTUs (British thermal units.) You can also check out this online calculator to determine the total BTUs of cooling needed for an LED light.

Controls

Lights with built-in or remote controls give you the freedom of programming. You may be able to set a timer, adjust the red, blue ratio of your light, or alter a light’s intensity to better suit your growing needs at any given time.

Included Accessories

If you’re setting up a grow room for the first time, you’re going to need a good amount of accessories to complete your installation. Consider it a bonus if a manufacturer includes ratchets, hooks, and/or other hardware with their grow lights.

Warranty

Most LEDs have promising lifespans, with many ranging between 20,000 and 100,000 hours of estimated runtime. While most LEDs live up to their promises, we still like to see companies stand behind their claims. Three-year warranties are commonplace for LED grow lights. A lengthy protection plan guarantees that you are covered even in the rare chance something goes from with your fixture.

Price

The cost of LED lights is yet another essential consideration. Most fixtures average in the hundreds, but professional models can cost much as $2,000 per unit. When you purchase an LED light, you’re making an upfront investment. You’ll reap the benefits of your investment so long as the fixture’s lifespan and light intensity live up to the manufacturer’s promise. Hopefully, you’ll opt for a model that also boasts a lengthy and worry-free warranty.

If you’re shopping with a limited budget, you’ll want to pay careful attention to the light intensity, spectrum, and coverage offered by your chosen light. The right light should present energy savings alongside healthy plant growth.

Wrapping Up

LED grow lights are a great way to improve your crop yields because they emit light in the wavelengths that plants require for photosynthesis. The best LED grow lights have warm-white and cool-white LEDs, which combined give you the ability to control the color temperature of your grow room. In this article, we will take you through questions about LED Grow Lights and provide reviews from other growers who use them as well!

What are the advantages of LED grow lights over HIDs?

LED grow lights are perfect for those who want to reduce their electricity costs, never have to worry about replacing the bulbs in an HID fixture, and can provide high-intensity light at low watts. LED grow lights appear cool because they use LEDs that emit blue or ultraviolet wavelengths of light rather than an incandescent bulb which emits yellow-red wavelengths.

The best advantage is cost savings! A standard 1000W metal halide lamp will cost around $250-$300 each time it needs replaced compared with just one more expensive but much lower-priced LED replacement bulb (around $30). This means you would need two fixtures if you were still using MH lamps instead of just one for your LED lighting system!

How far should grow lights be from plants?

There are a lot of factors that go into how far apart you should place your LED grow lights from the plants. The size and weight of your plant, the height it will be placed at, and whether or not you want to accommodate for air circulation all factor in. In general, many growers put their larger around two feet away on average when they’re using smaller lights containers like square gallon pots!

If you do plan on placing your plants closer than what’s recommended by the manufacturer then be sure to shield them with reflective materials so as to best to avoid any damage from light exposure!

The more common distance is between 18″ – 24″. This allows enough space for some airflow while still reducing energy because LEDs use very little wattage per square foot.

How long should grow lights be on for?

This really depends on the type of plant, but in general, we recommend 12 hours. This gives your plants enough time to absorb all the light and complete their photosynthesis cycle!

The two main factors that determine how long a grow light should stay are: How big is my space? What are you growing inside it? For small spaces we recommend turning them off at night or for dark periods like winter— this will save energy too! Larger areas can go longer without any problem if they’re using LED lights because LEDs use much less wattages per square foot as opposed to HID lighting systems which need lots of watts.

How many watts per square foot for led grow lights?

LED growers to report that they have been able to get similar yields on just 18″ of their plants by increasing the intensity of their fixtures which would work out to be roughly 66 watts per square foot if you’re bringing them closer together or even down to 36-watt hours per sq ft for larger spaces!

The watts per square foot for LED grow lights are much lower than HID lighting systems. For example, a 1000W MH light can use up to 200-400 Watts and produce around 60,000 lumens while an LED fixture with the same size might produce anywhere from 40-200 Lumens but only uses about 20 Watts! That’s as much as 80x less energy used when using LEDs vs. MHs in your grow space.

How to hang led grow lights?

There are many ways to hang LED grow lights, but some growers just use a simple chain. You can also purchase hooks and ceiling fixtures from stores like Lowes or Home Depot as well for the same purpose!

All you need is something that will be able to support the weight of your light fixture so it doesn’t fall down while being easy enough to access when needed for maintenance purposes too.

Keep in mind that if you’re using larger lamps then they might require more than one hook or length of chain depending on their size. This has been tested by other growers who have had success with this method though!

You may want to try hanging them at different levels throughout the space because LEDs produce higher intensity light which means there’s no need to place them as close together!

How to make your own led grow lights?

The most popular way to make homemade LEDs is with diodes (which are basically just little circuit boards) and some wires connecting them together.

How to choose led grow lights?

The best way to choose LED grows lights is by looking at the lumen output. The higher this number, the more intense light (lumens) it will produce! For example, if you’re using a 600-watt HID system then try and find an LED that has around 40 watts or less per square foot for optimal yield but with similar intensity.
