Top 600 Watt Grow Lights Picks

When picking the best 600w grow lights, you'll have multiple lighting types to consider, including High-Pressure Sodium (HPS), Ceramic Metal Halide (CMH), and LED. Each of the three lighting types has its advantages and disadvantages. You'll need to decide which meet your plants' essential cultivation requirements and have the potential to produce a yield acceptable to you. Factors to consider when picking the best 600-watt grow lights are intensity, spectrum, and coverage.

You'll also need to consider your budget. HPS and CMH lights are cheaper to buy, but LEDs are less expensive to operate because they consume a fraction of the electricity that the others do, and they last longer.

Best 600 Watt LED Grow Light Picks

Many LED grow lights labeled 600 watts consume about 400 watts when operated at full power. The lights recommended here are true 600w or higher fixtures; still, they are an energy-saving choice. Some LED lights can be set to use less than full power, such as during the vegetative growth stage when most plants do not require as much light as during the flowering stage. You can use a fixture that lets you turn off the LEDs or dial them back in intensity for even more significant energy savings.

A 600w LED grow light usually produces sufficient light to cultivate 10 to 14 plants.

Our top 600-watt LED grow light choices include:

Horticulture Lighting Group - Scorpion Rspec 600w LED Grow Light (120-240v) + LED Glasses

 

The HLG Scorpion R Spec works well for grow rooms with low ceiling heights or with vertical racks. It produces an even spread of light when positioned only 12 inches above the plant canopy. Another perk is that this LED grow light system is utterly dimmable, so you can control the wattage from 60 to 600 watts.

Iluminar iL8x 670W LED Grow Light Slim Low Clearance 8 Bar

 

The iL8X LED features additional diodes and a tuned spectrum for both vegetative and flower stages. You can use this with the Iluminar HASH Controller and the Iluminar App (Android and iPhone).

Growers Choice TSL ROI-E680 LED Grow Light - 680W

 

With the Growers Choice ROI-E680 Horticulture LED grow light, you'll have a balanced 3K  spectrum at 680W similar to that of a CMH lamp. It comes with a 120v power cord and a 240v adapter, but you can also order a 277v power cord. The high-performance light provides a complete, balanced spectrum for all growth phases.

Our Top 600-Watt High-Pressure Sodium (HPS) Picks

Many consider high-pressure sodium (HPS) grow lights old-school, but these lights with an orange cast are the gold standard in dependability.

Our top 600-watt high-pressure sodium (HPS) light choices include:

Gavita Pro 600/750 E-Series Flex DE Fixture 120-240V

Econo Magnetic 600w Package

 

This affordable 600-watt lighting package boasts a handy 6-inch air-cooled reflector. It comes with a 120/240 HPS magnetic ballast and a single 600-watt HPS lamp. The system is ideal for flowering and vegetative growth stages.

Our Top Ceramic Metal Halide (CMH) Picks

Ceramic metal halide (CMH) grow lights are valued for their high-quality light output. They feature an acceptable range of color rendering index (CRI) that nicely mimics natural sunlight.

Our top 600-watt ceramic metal halide (CMH) choices include:

Growers Choice 630w Horticultural CMH Lighting Fixture GC-630NS - 120-240v

 

This Growers Choice has two lamps positioned horizontally. It effectively mixes spectrums of plant growth during all stages. The ballast is dimmable, and it has an open-air reflector for efficient cooling. You can control this light with either the Gavita EL1 or the EL2 controller.

Gavita Pro CMH 630e 208-240 Volt Complete Fixture

 

The Gavita Pro CMH 630e works well for extensive cultivations in either greenhouse or indoors. It comes with the Philips 315 watt 3100K lamps (for flowering) or 4200K lamps.

Prism Lighting Science 630w Ceramic MH (CMH) Fixture 120-240v (No Lamp)

 

It should be noted that the Prism Lighting Science fixture does not come with a lamp. You'll need to purchase this separately. It is suitable for two 315W Ceramic Metal Halide Lamps.

Whether you pick 600W high-pressure sodium (HPS), ceramic metal halide (CMH), or LED lights may depend on the details. CMH lamps use less power than HPS, and LEDs use less than CMH. Similarly, CMH lamps run cooler than HPs, and LEDs run cooler than CMH. Any of these fixtures, if used within manufacturers' guidelines, should produce satisfactory yields.
