Last updated: April 13, 2021

Looking for the perfect lighting system for a grow takes a lot of work between actual research and getting through the litany of marketing copy and reviews online. It’s a big industry these days, and especially so with LEDs.

To get the most out of an LED system you need a light that can provide the proper spectrums to your plant during all stages of growth. Cannabis, in particular, tends to respond to different colors depending on whether it’s a seedling, vegetating or in the flowering stage.

Let’s take a look at the best 600w LEDs we’ve found on the market for both general and niche use. Read on at your leisure and take the time to make an informed decision.

  • The 8 Best 600w LED Grow Lights – Reviews 2021

    1. VIVOSUN 600W Led Grow Light – Best Overall

    VIVOSUN 600W Led Grow Light-100px

    The VIVOSUN 600W LED Grow Light is an incredibly bright LED with both bloom and vegetative functionality for a great price but lacks in its overall lifespan. It’s a great beginner’s choice for a grow or two.

    Being able to swap between red and blue spectrum is optimal for getting the biggest growth with LED lights. As opposed to lights that cover a balanced spectrum, which tend to be a jack of all trades but master of none situation, this lighting system can easily get the best growth all the way from seedlings to flowers.

    Unfortunately, the fans are a bit noisy and due to some skimping in build quality, parts of this light seem likely to fail after about two grows. Still, the price is right, and it will work quite well for the purpose of massive yields in a medium grow – while it lasts.

    Pros
    • Bright bloom and vegetative options
    • Great price
    • Good for beginners
    Cons
    • Most likely will fail after two grows
    • Fans are noisy

    2. BLOOMSPECT B600 LED Grow Light – Best Value

    BLOOMSPECT B600 LED Grow Light-100px

    The BLOOMSPECT B600 is capable of moderate growth at an astoundingly good price, but lacks the light spectrum needed for explosive growth in flowering plants. Its quality is pretty solid for the price and comes with a good warranty in case of issues.

    A jack-of-all-trades light that has just enough light for a small to medium grow with some quality, if not massive plants. Worthwhile to have for those trying to keep on a budget and just looking for something that will definitely take care of their plants, so long as you’re not worried about the most optimal light spectrum during each specific life phase.

    The build quality is surprisingly good as well, which helps make this decision for us to call this one of the best 600W LED grow lights for the money. The brightness is somewhat lacking compared to more expensive models, but as long as you keep this close to your plant throughout the grow it will create results.

    Pros
    • One of the best-priced LEDs on the market
    • Can handle plants from seedling to flowering
    Cons
    • Not as bright as more expensive models
    • The light spectrum isn’t ideal for explosive growth

    3. VIPARSPECTRA PAR600T LED Grow Light – Premium Choice

    VIPARSPECTRA PAR600T LED Grow Light-100px

    An impressive, cool, and quiet LED that will last and last. One of the brighter 600W LEDs on the market that offers both bloom and vegetating light spectrums. It may be out of the price range of some growers, but it is definitely an investment worth considering.

    The standout feature with this lighting system is the lenses they use to focus its diodes. They are very well designed and as a result, create an incredibly focused and bright environment for any plants growing underneath this system.

    Furthermore, the fan system works quite well to keep these lights cool and operate much quieter than anything else we’ve checked out so far. The remote included with this system also helps the growers avoid blinding themselves while making adjustments.

    Price-wise, it’s not that bad, but it requires an amount of investment from the grower, so it may be a bit out of reach for some new growers. Highly recommended, but not there are cheaper options on the market.

    Pros
    • Incredibly bright and focused
    • Bloom and vegetative switches
    Cons
    • It’s an investment out of reach of some new growers
    • There are cheaper options with similar potential on the market

    4. Phlizon LED Plant Grow Light

    Phlizon LED Plant Grow Light

    Phlizon offers a low price for a double switch LED light. It’s basic on all other aspects, and lacks a bit of brightness, but does operate at a cool temperature and the fans are fairly quality. The build quality seems to be up to snuff, but overall it might be a bit disappointing for growers looking for something a bit more.

    It’s a very basic LED system for a good price, which is why it makes the list; however, its brightness seems a bit lacking when not directly on the plant. This is partly due to a design decision with these types of systems wherein they forgo reflectors to try to keep the lights cooler.

    On the surface, this seems like a good idea, but reflectors are important to keep light spread minimum and increase the magnitude of any light created. It’s still bright enough for a small grow, but should be set very closely with whichever plant it is being used on.

    Pros
    • Good price
    • Both veg and bloom modes
    Cons
    • Lacks brightness
    • Needs to be set very close to a plant

    5. KingLED LED Grow Light

    KingLED LED Grow Light

    The KingLED grow light stands apart from others on this list due to a design decision that focuses on keeping the lighting as cool as possible. On top of this, it offers both bloom and vegetative switches, however, it’s lacking a lot in the brightness needed for large plants outside of a small grow.

    Putting this inside some kind of enclosed environment like a closet or grow tents seems to be what they were going for when designing this. It doesn’t add much heat to the environment, while still being somewhat bright, but it seems like it would need either mylar around the grow or supplemental lighting to get the best possible results.

    Definitely not ideal for a grow room, but it’s potentially a good option for a small grow tent catering to 3 or fewer plants. The price is right as well, and the stealth factor should be noted due to how quiet these fans are.

    Pros
    • Very little heat
    • Quiet
    Cons
    • Not very bright
    • Best for small spaces with few plants

    6. MARS HYDRO TS LED Grow Light

    MARS HYDRO TS LED Grow Light

    A powerful daylight spectrum light that works well for seedlings and vegetation, but lacks the red spectrum needed for the best possible flowering growth. Still, it’s a cool-running light and is bright enough to sustain plants, even if they don’t get huge during flowering.

    This is best for a large seedling operation or in conjunction with a supplemental red spectrum LED. A MARS HYDRO plus a power red spectrum light on a plant will absolutely create large and beautiful buds, but by itself, it might be a bit disappointing.

    The stealth factor is very pronounced in this light, as it requires no fans and draws very little power. This, plus the price, makes it a good option for constant stealth grows that are more worried about keeping things on the down-low and consistent, over huge yields.

    Pros
    • Noiseless and cool
    • Great for seedling and vegetation
    Cons
    • Not good for flowering plants
    • Needs a supplemental red LED for best results

    7. MAXSISUN LED Grow Light

    MAXSISUN LED Grow Light

    The MAXSISUN LED Grow Light is a very efficient LED lighting system meant to handle small grows all the way into flowering. The chip system used here is surprisingly bright for the small amount of power used, though the claimed 600W equivalence may be a bit of an exaggeration.

    Truthfully, this seems more like a 400-450W equivalent lighting system. Which is still great for a three or so plant grow, but is a bit misleading for people looking for something more powerful. However, the price is hard to beat for a small grow.

    This hits the lower end of this list due to this reason. Otherwise, it’s a cool running LED system with a solid budget-built quality that handles small grows just fine. Don’t go into this purchase expecting a true 600W equivalency and you won’t be disappointed.

    Pros
    • Good light spectrum
    • Solid budget build quality
    Cons
    • Only suitable for small grows
    • Not true a true 600W equivalence

    8. Growstar Reflector Series LED Grow Light

    Growstar Reflector Series LED Grow Light

    Another misleading LED system that is great otherwise, but does not have the 600W brightness as claimed by the manufacturer. Otherwise, it’s a good choice for small grows looking for a well-built budget lamp that doesn’t make a lot of noise.

    Despite the great reviews people have for this product, the claimed power here is quite a bit off of what this lamp is capable of. It’s much closer to 400W, which is still great for a small grow or an enclosed spaced with a lot of reflection.

    All in all, it’s a good system, but make sure to use it with a lot of reflection on a small grow for the best results.

    Pros
    • Quiet
    Cons
    • Misleading advertising
    • Needs a lot of mylar or only on a small grow

    Conclusion

    A 600W LED system is a great way to grow without breaking the budget on climate control and power bills. Navigating through the reviews of these products takes time, and a fair amount of it can be misleading especially when it comes to the true brightness, they are capable of producing.

    We recommend the VIVOSUN 600W Led Grow Light for most growers. It is capable of a true 600W equivalency while also having the option of swapping between vegetative and blooming grow modes, and the price isn’t bad either.

    For anyone looking for a longer-lasting product with a higher build quality, but is still capable of producing a lot of light, then look no further than the VIPARSPECTRA PAR600T LED Grow Light. It’s quiet, it runs cool, and it will last for quite a few grows before anything goes wrong.

    Finally, the best budget lamp we could find that also seemed to be about 600W, or at least somewhat close to that strength, was the BLOOMSPECT 600W LED Grow Light. It might be a bit duller than the others we just recommended, but it’s not overly misleading. A bit of extra reflection can help fill that gap easily.

    We hope this helped get through some of the more complex questions you might have when searching through LED grow light reviews. It can be tough to make a decision, so take your time.
