Best Overall: MARS HYDRO TS
- Ideal for commercial use - auto-sensing power supply works on 277VAC, 240VAC, and 120VAC
- Provide 30% higher yield and 20% more the light intensity than the traditional LED lights - newest SMD LED technology & aluminum light boards design
- Noise-free – fan-less design
For commercial setups or large rooms, we immensely suggest the MARS HYDRO TS.
While featuring an auto-sensing power supply that works on both 277VAC, 240VAC, and 120VAC, it has two dimmable and waterproof Mean Well Drivers – same as spider farmer 4000 but costs much cheaper.
It is known for providing a 30% higher yield and 20% more the light intensity compared to the traditional LED lights.
That is a big thank you to the newest SMD LED technology and fan-less aluminum light boards design.
They allow the plants to receive more energy yet not burnt leaves and can get the max yield at 2.5g/watt. Perfect for 4' x 4' bloom stage or 5' x 5' veg stage.

Best For Beginners: King Plus 1000w
- Shine brighter without burning leaves – provide a full spectrum of light at 50°F to 60°F
- Optimize the light for specific growth stages of plants – feature Veg/Bloom switch
- Energy-efficient and money-saving – adopt a hi-tech LED chip

The most disturbing thing for starter gardeners is fears of inefficient plant growth or even making them die due to the lack of experience.
But with this King Plus 1000w, you’ll get lots of peace in mind.
It emits a full spectrum of light at only 50°F to 60°F, which is significantly lower than other grow lamps to prevent burning your plants. The biggest selling point is its Veg/Bloom switch that ensures providing the right amount of light for plants at different growth stages.
Bloom switch includes white and red LEDs while the Veg switch is white and blue for seed and seedling growth.
By adopting a hi-tech LED chip for brighter lighting but less electricity consumption, it is a nice alternative for the traditional 600W HPS and helps you save tons of money.

Best For Vegetables: MARS HYDRO SP
- Superior longevity and durability - 50% longer lifespan compared with other brand lights and IP65 waterproof standard
- Thrive veggies to grow faster and more beautifully - full-spectrum, covered with UV and IR
- 30% higher yield compared to the traditional LED models – provide the Max 2.5g yield/wattage of power draw
- Run quietly
- No dimmer option
- No power switch
Out of many candidates, this LED grow light stands out for its performance on our vegetables, especially leafy greens.
It puts out enough light with full-spectrum, covered with UV and IR, to make them grow beautifully. If you’re noise-sensitive, just rest the heart as this model is designed in a noise-free fan-less LED light bar.
What satisfies us the most is the Max 2.5g yield/wattage of power draw, equivalent to 30% higher yield compared to the traditional LED models. Meanwhile, the true output of this model is just 230W.
In other words, this is a more scientific and energy-efficient replacement for the single-ended 2000watt HPS.

How To Choose The Highest Yielding Led Grow Lights?
- For the comprehensive development of plants, we highly recommend going for LED grow lights that emit a full range of the spectrum, including UV light.
- The reason is full-spectrum yields generate little heat while running to hence require no additional fans. Additionally, they’re durable and cost less in the long term of use so that your electricity bills won’t be piled up.
- The most important thing is to have a high-intensity light with various wavelengths to encourage plants to grow comprehensively and healthily.
Spacing & Wattage
- These two elements have a close connection to each other because each grow light features a specific range of coverage areas. If they don’t match together, it results in either energy inefficiency or unhealthy plant growth.
- Let start with calculating the amount of space that you want to cover with grow lights.
- Then figure out the real wattage value.
- Many LED light manufacturers give their specific product a name like “King Plus 1000w” or “BESTVA DC Series 2000W”. The confusing thing here is the “1000w” and “2000w”. They are actually NOT the real wattage value of the light.
- If taking a look at each product specs table, you’ll see that the real wattage value of King Plus 1000w is just 185W and the BESTVA DC Series 2000W’s is 390W.
- Now, once you’ve got these two numbers, compare to find out the most suitable option for your needs and your plants, following this basic rule of thumb:
- For each square foot, there should be at least 50W with a LED grow light.
- For example, if the coverage area needed to lighten is 3’ x 3’, you should look for a LED grow light featuring 3x3x50 = 450W as a minimum.
Which Brands Make The Highest Yielding Led Grow Lights?
- MARS HYDRO is one of the most reliable brands out there that are specialized in manufacturing high-quality lights. Their products are ETL listed and CE, Rohs approved for extreme safety with the detective rate controlled within 0.5%.
- This is the leading brand in China with a solid reputation gained from its long-standing history. They are specialized in LED aquarium lights and LED Grow lights, and known for providing continuously improved products in both design and innovation.
- BESTVA is more specialized in LED grow lights than the other two and they provide a wide range of related products to ensure you will get at least one best option for your plants. Above all, they provide you with a 3-year warranty.
Can any LED light be used as a grow light?
Literally yes, it can, just NOT as efficiently as a specialized grow light.
What color light is best for plant growth?
A full spectrum, including the UV light.
Best LED grow light for 4X4 grow tent?
It should feature at least 900W of real wattage value.
Does more light equal more yield?
Yes, it does.
The bigger the light, the better the penetration, leading to the more yield.
How much does it cost to run a 1000w LED Grow Light?
This depends on the number of lighting hours per day and kWH cost in your area. For example, in our case, we run grow lights 16 hours/day and the kWh cost is 0.1, so it costs nearly $53/month.
In the end, your budget and plants’ needs should take precedence in your purchase decision. But we hope that by providing you with the highest yielding LED grow light reviews, we can help you make the best-informed decision.
That’s all for this post.
