5 Best Professional LED Grow Lights: Your Buyer’s Guide

The MarsHydro 2000W Full Spectrum Grow Light stands out because it’s perfect for commercial growers. You can daisy-chain up to 15 of these lights, while still being able to conveniently control all of them with one main light.

This is perfect for an area of 3’x5′ when you’re in veg, and 2’x4′ when your plants are flowering.

These lights are also quiet. The quantum lights board design means these are fan-less (while still efficiently dispersing heat), so you won’t have a super noisy grow room.

These include an easy dimming function for further customization.

The Roleadro 1000W Full Spectrum LED Grow Light stands out because it’s a Chip On Board (COB) LED grow light.

COB LEDs consist of multiple individual LED diodes mounted on a board, which can be made from silicon carbide, sapphire, copper, or other reflective materials. These diodes produce light arrays.

COB lights are very bright and emit white light (rather than red or blue). They are full spectrum, providing light that is closer to natural sunlight than non-full-spectrum grow lights.

This 1000W COB light from Roleadro is surprisingly small for the amount of light it produces. If you want to try out COB technology with a very powerful light, this is a great choice.

Roleadro also makes professional LED grow lights in other wattages, which can be daisy-chained with this one.

The Dimgogo 1500W LED Grow Light stands out because Dimgogo is a newer brand in the industry, but their lights have proven to be excellent quality.

Customers love the excellent customer service they receive from Dimgogo’s parent company. (The lights come with a 3-year warranty.)

This light consists of triple-chip 10W LEDs, which are brighter and more efficient than double-chip 3W or 5W LEDs. This can have a huge impact on your plants’ growth speed and quality.

This grow light includes red, blue, white, IR, and UV LEDs, giving it a full spectrum that is closer to sunlight than grow lights with only red and blue diodes. This is a powerful light with an equally powerful cooling system. Two fans and a large heat sink keep this light running cool. This light consumes only about 185W of power and is great for about a 5′ by 4′ growing space.

The Apollo Horticulture GL140X5LED Full Spectrum 700W stands out because Apollo is one of the most well known and trusted brands in hydroponics.

This grow light is straightforward and easy to use, without any complicated technology or extra features. These lights come in several wattages.

It consists of 5W LED chips, and has a lifespan of 50,000 hours.

It comes with a limited 2-year warranty. This light is a powerhouse designed for professional use, and hundreds of positive customer reviews are a testament to its quality and reliability.

The Advanced Platinum Series P600 600w Full Spectrum Grow Light stands out because Platinum lights are some of the most powerful LED grow lights on the market. This brand boasts the highest PAR/lumen output per watt of any competing brand.

They also use top-quality LEDs made by American brands like CREE. CREE is a newer brand to the scene of horticulture and hydroponics, but their LEDs are making a huge impact on the industry. Their high performance white and color LEDs are optimized to have a full spectrum of light that is optimal for plant growth. These LEDs have the highest output in the industry, and come the closest to actually replacing HPS or HID lighting, without the extra cost of heat output and wattage.

This grow light from Advanced Platinum combines CREE technology with the know-how and years of experience of Advanced Platinum, a great brand that has been around for many years.

This includes a 5-year full warranty.

The VIPARSPECTRA Dimmable Series PAR1200 1200W LED Grow Light stands out because dimmable grow lights allow you to customize exactly how much of each growth stage lighting spectrum you want your plants.

If you want a high level of customization, regular veg and bloom switches do not cut it. Dimmable grow lights allow you to customize exactly how much of each growth stage lighting spectrum you want your plants exposed to. This means you can have different settings for early veg and late veg, early bloom and late bloom, and a booster setting for the end of bloom.

Plus, if you’re a super observant, hands-on grower, you can go into your garden every day, and adjust the levels based on your observations of your plants. This kind of daily observation sets professional growers apart from hobbyists, and allows you to produce the highest quality buds from your plants.

This grow light also comes with a 3-year warranty plus a 30-day satisfaction guarantee.
