MARS HYDRO TS 1000W has a very high output power, which is suitable for large rooms. It consumes just 150W and produces about 1000W output. This impressive electricity efficiency is due to its high reflective design.
The light intensity is increased up to 20%, so the plant receives more energy; yet the heat dispersing hosing keeps the plant from being burned. MARS HYDRO TS 1000W features no fans, so it makes no noise while operating. However, this makes the LEDs and the housing get very hot, may reduce its lifespan.

Best For Herbs: Roleadro 1000W Grow Light
- Extracts the most useful lights from the full spectrum
- Higher PAR value and Lumen output
- Exclusive LED Bead & Zener Design
- Effective Heat-Removal System
- Narrow lighting angle
Roleadro 1000W is a unique grow light. It extracts the most useful lights from the full spectrum, which means the light it produces is even better than sunlight; so the yield can increase by up to 50%.
Roleadro 1000W provides higher PAR value and Lumen output. The higher these values are, the better for the photosynthesis of the plant. Most of the led grow lights have the reflector design to enhance the electricity efficiency and light density, however, Roleadro 1000W does not. It features exclusive LED Bead & Zener Design so that every LED can work independently and if one LED is broken, it won’t affect nearby LEDs. Moreover, LED Bead & Zener Design can stand even higher than 70℉.
In addition to an aluminum heat sink and two high-speed fans, Roleadro 1000W features a built-in temperature controller to quickly dissipate, keeping the lamp cool and durable.
There is only one drawback, which is that the lighting angle is a bit narrow - just 90 degrees. So the lamp won’t cover a very large area.

Best For Grow Tents: King Plus 1200w LED Grow
- High output power
- Veg & Bloom switches
- Energy-saving technology
- Powerful cooling system
- 3-year Professional Service & 90-day free return
- Not waterproof
King Plus 1200w consumes only 185W but produces an impressive output power, 1200W. The lamp has two modes: Veg and Bloom. The Veg mode includes blue LEDs and white LEDs for plant’s germination, sprouting, and root development phases. The Bloom mode includes red LEDs and white LEDs, preventing chlorophyll from breaking down. When both switches are on, all the LEDs are on, especially good for flowering and fruiting phases.
Like other lamps above, King Plus 1200w features a powerful cooling system, enduring a withstandable temperature, enhancing the lifespan of the lamp. With the price, I expect King Plus 1200w is waterproof but it is not. This is considered a drawback.

King Plus 1200w has high output power and high energy efficiency, ideal for grow tents.
How To Choose The Best Full Spectrum Led Grow Lights?
PPFD Value & PAR Value/Lumen are two crucial specs. These two specs show the light density. The higher the light density is, the better the photosynthesis of the plant is.
Input and output wattage: You may want to compare these two wattages. Some lamps with special design allow them to multiply the input wattage and produce impressive output power. Such as, MARS HYDRO TS 1000W consumes only 150W but produces 1000W thanks to the Reflector design.
Lifespan: A led grow light should last at least 50,000 hours. Some even last for more than 100,000 hours.
Other things you may examine when choosing a led grow light are Lighting angle, Lighting field, Timer function, Cooling system, and Safety features.

Are all LED lights full spectrum?
No. Even white LED lights don’t produce a full spectrum. If you want a full spectrum LED light to grow plants indoors, you’ll need a specialized one.
How many watts per plant for LED Grow Lights?
You'll need at least 32W/sq.ft. However, I recommend about 50 - 80W/sq.ft.
How far should LED Grow Lights be from plants?
Here are some suggestions
- Acclimation Period: 36-40 inches
- Young Vegetative: 32-36 inches
- Vegetative Stage: 24-32 inches
- Flowering Stage: 12-24 inches
What are the pros and cons of LED Grow Lights vs. HPS?
Overall, I favor a full spectrum LED light over an HPS (High Pressure Sodium) light. First, full-spectrum LED lights produce IR to UV wavelengths, which is sunlike, wwhileHPS lights only produce red and orange wavelengths. Second, LEDs are more environment friendly as HPS lights use toxic gas and metals. Third, LEDs are more energy-efficient. And last, LEDs have lower operating temps and last longer.
How long should i keep the light run every day?
Here are some suggestions
- Acclimation Period: 10 hours (VEG mode)
- Young Vegetative: 12 hours (VEG mode)
- Vegetative Stage: 18 hours (VEG & BLOOM mode)
- Flowering Stage: 12 hours (VEG & BLOOM mode)
Full-spectrum LED Grow Lights are one of the best options for indoor hydroponic. I hope this review can help you choose the best fit grow lamp for your small garden.
