03. Mars Hydro TS 1000 Watt Set Review

 Check Price On Amazon

Mars Hydro is one of the famous names in the grow light industry. That’s due to their affordable products and excellent service. The reason we think it may be the best 1000 watt led grow light for you is because it comes with literally everything you need.

You don’t just get a 1000 watt LED grow light. You get a hanging kit, timer and digital temperature sensor. This unit gets points for being easy to set up. For example, the timer is built into the power plug, reducing how much you have to plug in and connect to get started.

The built in reflectors add power to the lights, but this does increase the risk of burning plants closest to the LED lights. A different issue is the heat output. These lights generate a lot of heat, though most of this is distributed by the fans and heat sinks. Do not use this in an enclosed space without good ventilation, or else the temperature will get too high.

The lights are dimmable. Dimming the lights reduces the energy usage and heat generation. An occasional problem with this model is that the lights may flicker, though that doesn’t always lead to lights burning out. On the other hand, the light itself is unlikely to strain your eyes, though you’re still advised to wear protective goggles. You may see specific bulbs dim or burn out without the rest burning out.

We’ll say this grow light is perfect for providing enough light to mimic natural sunlight for a 2×2 growing area or supplemental light for a 3×3 growing area. The concentrators mean it isn’t going to deliver much light to the edges of the coverage area.


  •  Comes with everything you need, including what others make you buy as extras
  •  Dimmable
  •  Greater reliability


  •  Runs hot

01.6. King Plus 1000W LED Grow Light Review

Check Price On Amazon

The first thing of note is that the King Plus light uses 10W double semiconductor chips. This is much stronger than the more common 1W, 3W and 5W chips. Not only that, but this grow light is engineered for a perfect PAR/lumen balance. Not only that, but the lights have been made to last longer and provide the best coverage possible.

At just 185W power consumption, this does a wonderful job of converting energy and saving you money. LED grow lights are always great at saving money due to their reduced energy, but this offers you some superior savings. The lights are full spectrum. You get the all-important red and blue along with yellow, white, UV and IR, making it just like the sun.

The cooling system is top-notch and will keep the light at a good temperature during operation. Holes have been added to the LED board for efficient cooling and there are two fans for superior heat dissipation.

While many LED lights have holes in the board, these holes are twice as wide for better cooling. The LEDs have been made to resist heat, which will prevent them from malfunctioning in case of a problem.

For those who want a big, strong LED grow light in the 1000W range, then it doesn’t get much better than this. King Plus is a powerful brand and they stand by their products. You can also daisy chain a few lights together if you need even more coverage, just plug one light into another until you’ve got everything in place.


  • Surprisingly affordable considering the power and features you’re getting
  • Some of the strongest semiconductor chips available at 10W with full spectrum lighting
  • Very low power consumption at 185W


  • Some think there is too much blue light, which makes this better for vegetating than flowering

01. Sunraise Brand 1000 Watt LED Grow light Review

Check Price On Amazon


This is the best 1000 watt led grow light for someone on a budget. It is affordable, yet it provides all the light you need. You can put out nearly entirely red light, a mix of red and blue light or full spectrum light. You can make that switch by literally flipping a switch.

The manufacturer uses optical lenses to concentrate light and deliver deep penetration. However, this raises the risk of sun-burning the top layer of leaves. And it means the grow light only really puts out intense light for the core area under the grow light.

The grow light by Sunraise is ideal for a two foot by two foot growing area when you want to replace natural sunlight. It can in theory provide supplemental light for a 3 foot by 3 foot growing area, but that requires removing the LED lenses. Note that the blue light is heavier with this model than others on our list.

The grow lights can be daisy-chained, and this can be done with the same power cord you use to plug it into the wall. You can daisy chain up to three of this model in series and plug the last one into the wall. It can use power anywhere from 100 to 240 volts. It can accept input power at 50 to 60 Hz.

The unit is described as a 1000 watt grow light. Its output is closer to a 500 watt HPS bulb. However, it uses less than 200 watts of power.

This board is subject to a higher than average rate of electrical problems. And it isn’t just burned out bulbs. Sometimes things spark before dying, because the units aren’t always properly grounded. A warning sign of this is when it shocks you after you plug it in. If this happens, don’t use it, because you cannot fix it. The risk of these failures goes up in a humid environment.


  •  Easy to use
  •  Includes most of what you need out of the box


  • Small coverage area
  • Less powerful than advertised

02. Giixer Brand 1000 Watt Grow light Review

Check Price On Amazon

Giixer is a relatively unknown brand. However, they’re a decent option. The manufacturer provides a hanging kit, power cable and temperature gauge. The temperature gauge is a simple dial meter, not a digital display, but that doesn’t matter to everyone. There are occasional complaints that the manufacturer ships units without all the promised hardware.

The grow light puts out a broad spectrum light that supports all stages of plant growth, from nurturing seedlings to fruiting plants. The unit does put out both red and blue light in equal measure. The unit is advertised as a 1000 watt grow light but has light output closer to that of a 300 to 400 watt HPS light.

The powerful fan keeps it cool, but it is loud. The fan itself often shorts out, and that could even cause smoke or a fire hazard, though this is rare. The electrical system for the lights is more prone to total failure than others on our list, whereas other products may see a cascading failure of lights until the unit goes dark.

This could happen anywhere from one month after purchase to two years of heavy use. When that happens, the fans and controls die, too. Flickering is a warning it is about to die. Return it if that happens. On the flip side, if one or two lights don’t work out of the box, that doesn’t mean it is going to go dark after a few weeks of continual use.

The coverage area for this grow light is advertised as three feet by three feet. If you’re trying to replace all natural light, the effective growing area is 2 feet by 2 feet, 2.5×2.5 at most. It can provide supplemental light for plants in a 2.5×2.5 or 3×3 area.

This unit is not water-proof. In fact, it isn’t water-resistant. In a humid environment, the exposed metal components will rust.


  • Comes with basic essentials out of the box
  • High levels of both red and blue light


  • Fan is loud
  • Electrical problems

02.1000 Watt LED Grow Light Yield

Many factors go into calculating the yield of 1000W LED grow lights or grow lights of any other strength. That’s because every plant and light is different, so there’s no way to give a flat yield amount. The first factor is the plant you’re growing. Some plants will grow rapidly while others need more time to spring up, so take that into account.

You must also consider the grow light and the chips used. Wattage is important, but the chips are arguably more important. Single-chip lights tend to be the cheapest and yield less than double-chip grow lights. You’ll find that most LED grow lights have flowering and vegetating lights that can improve yield and reduce energy if used properly.

A 1000W LED grow light should yield around 1g to 1.5g per watt. You can expect about 1,000g to 1,500g with these grow lights. Remember the factors above can change this amount, but chances are your yield will be within this range.

HPS grow lights, by contrast, only yield 0.5g per watt. This means LED lights produce two to three times the yield and they also need less power. LED grow lights are clearly the superior of the two and you’ll see when harvest time comes around.

04.1000 Watt LED Grow Light Buying Tips

You need a full spectrum light if you want the most from your 1000W LED grow light. These lights are made to feed plants all the different colors they need for optimal growth. Most grow lights come with at least red and blue, which are the two most important colors, but full spectrum fills in the gaps and it’s even better.

Semiconductor chips determine how powerful the LED grow light is. In general, the semiconductor chips are usually available in 1W, 3W and 5W types. While 1W is perfectly suitable for plant growth and can be used in most situations, it’s often best to choose either the 3W or 5W because they are much stronger and can produce better growth.

LEDs are very susceptible to heat damage. While LED grow lights are much cooler than other light types, you still want to make sure you that you choose a 1000W grow light with good heat management. This includes fans and a heat sink. These reduce to the heat to a safe level.

The last thing to consider is ease of installation and use. While some LED grow lights are more advanced, you shouldn’t choose a grow light that is impossible to use.


If you’re looking to get a tremendous yield and make the most of your indoor growing area, then these are the best 1000 watt LED grow lights you can find. Not only are these lights very powerful, but they have a ton of features that you’re sure to love.

Regardless of what you’re growing, you’ll find all the lights on this list will help you get your biggest yield yet. It’s just a matter of remembering your preferences and getting the best light for your unique needs. Best of all, these lights are very affordable so you can add several to your growing area.
