Best LED Grow Lights Under $100

the best LED grow lights under $100

A few years ago, finding a decent LED grow light under $100 would have been impossible. Even $500 or $1000 was hard.

Don’t get me wrong: there were always tons of lights in this price range. The problem was that none of them were any good. Few would do much of anything and none were able to flower effectively.

These days, most lights under a hundred dollars are still worthless. But a few of the Chinese manufacturers have stepped up their game and are now making good quality lights. And their lower wattage light cost less than $100.

We’ve researched the hundreds of lights in this range and found the ones that are actually worth getting. These 5 LED fixtures and one bulb are the best LEDs you’ll find under $100.

Disclaimer: several of the lights on this page are often on sale for under $100, but their actual retail price is above $100. It is not guaranteed that their price will always be less than $100.

The 6 Best LED Grow Lights Under $100

I will just sum up my findings briefly.

  • If you are looking for an LED bulb as supplemental lighting, nothing beats the TaoTronics
  • If you need a light for vegging only, get the Viparspectra.
  • If you prefer white light, the Roleadro 300 is by far the best full-spectrum white LED in this price range.
  • If you need a light for all stages or for flowering only, check the current prices on the Mars 300, the Galaxy Hydro 300 and the Meizhi 300 and get whichever one is priced lowest (unless you want white LEDs; then see previous point).

 

VIPARSPECTRA Reflector Series 300 Watt LED Grow Light

This 300 watt fixture is part of the Viparspectra Reflector Series, which consists of 5 lights in total, ranging from 300 watts to 1200 watts (head to Amazon for info on the rest). The 300w version actually uses 136 watts and is equivalent to a 250 watt HID light.

The Viparspectra series are full spectrum lights that work for all stages of plant growth. That said, I feel the inclusion of so much blue light makes them better vegging lights than flowering lights, although they can be used for both. Personally, I would go with a different fixture if I were planning on using it for all growth stages.

This is a powerful light that delivers a PAR value of 850 umol in the center at 12 inches from the canopy. If you move it back to 18 inches, you get 483 umol and at 24 inches, you get 300 umol. When you hang the light 2 feet above the canopy, you can expect a core coverage area of 2 by 2 feet; the max coverage is given at 3 by 3 feet, but for flowering, you will not get more than 2 by 2.

The Viparspectra Reflector Series uses high intensity 5 watt Bridgelux/Epileds LED chips, so you get much deeper canopy penetration than you do with standard 3 watt chips. The main drawback is heat, but the combination of 4.72” fans and large 0.8 inch aluminum heat sinks are able to dissipate it effectively.

Features

  • Uses 136 watts — save about 50% on your electric bill over HID lights
  • Equivalent to a 250 watt HID system — but costs less to buy AND to operate
  • Full spectrum light — can be used during all stages of growth
  • 2 by 2 foot core coverage — equivalent to HID or competing LEDs
  • 90° degree lenses — focus all the light onto your plants, so none goes to waste
  • Runs on AC100-240V — will work in any country
  • Rated for 100,000 hours — 8-10 years with no bulb changes
  • Includes light, hanging kit and power cord — everything you need to start growing immediately

 

Summary

This is a great light at a very low cost. That said, I would not get it if I needed a light for all grow cycles. It can flower just fine, but not as well as a light with more red and white spectrum diodes. The heavier use of blue diodes makes this light ideally suited for vegging and I would only buy it for that purpose or if I wanted to supplement an existing lighting system.

TaoTronics 24 Watt LED Grow light Bulb

In addition to this 24 watt grow bulb, TaoTronics also make a 12 watt version and a 36 watt version. Obviously these bulbs are a bit different than the other lights on this list, but I thought it would make sense to include them anyway.

For one, they cost much less than the other lights, but they are also much less powerful. In fact, even the 36 watt one is not going to be strong enough to flower any plants on its own. But that is not their purpose anyway.

These bulbs are meant as supplemental lighting. You can use them in addition to natural daylight or to supplement an existing horticultural lighting system. You can screw them into any standard E26 light socket (the kind you already have all over your home), making them much more flexible and easier to use than regular LED fixtures.

All of the TaoTronics bulbs have 12 diodes. The 12w bulb uses 1w chips, the 24w bulb uses 2w chips and the 36w bulbs uses 3w chips. The 24w version has 2 blue LEDs with a 460 nm wavelength and 10 red LEDs, 3 at 660 nm and 7 at 630 nm. The 36w version is the same, while the 12w version has one more blue LED and one less 630 nm LED.

These bulbs have a lifespan of 50,000 hours. The use aircraft grade aluminum and a unique heat sink design to maximize heat dissipation. This keeps them running cool at all times, even after 24 hours of continuous use. TaoTronics bulbs come with a 12 month warranty plus 6 months extended after registration.

MarsHydro Mars 300 LED Grow Light

Mars Hydro are well-known for making quality lights at very low prices and the Mars 300 is no exception. It is made with high-quality materials, like a plug with VDE and UL certification wires, an adopting isolated power supply and a heatproof tube, so there is no risk of catching fire. Everything is covered by a 1-year warranty and a 30-day return policy.

The Mars 300 contains a mix of red (620~630 nm and 650~660 nm), blue (450~475 nm) and white diodes to give you a full-spectrum light that works during any growth cycle. The ratio of red to blue to white is specially selected to provide only the light plants actually use. This maximizes plant growth and yields and minimizes power consumption and heat.

The Mars 300 uses 60 five-watt LEDs and consumes around 132 watts of power. It is about equivalent to a 250 watt HID lighting system. It covers a 2 foot by 2 foot area during vegging and a 1.5 foot by 1.5 foot area during the bloom cycle. The light has a lifespan of 50,000 to 100,000 hours and ships with a power cord and a steel hanging kit.

Roleadro 300 Watt Full Spectrum White LED Plant Light

Roleadro’s 2nd Generation 300 Watt Full-Spectrum White LED light has been redesigned with an improved spectrum. It uses warmer 3000K light that is even better for flowering. The light includes wavelengths from 420 nm to 780 nm, i.e. purple, blue, green, yellow and red light.

One big advantage of all-white LEDs is that each diode emits the full-spectrum. This makes for a much more uniform light than a fixture that has a blue diode here, a red diode there, etc. Overall, the light this fixture emits is very close to natural sunlight, so you know your plants will love it.

The 300w Roleadro this plant light has a mixture of 90 degree and 120 degree lenses. The 90 degree lenses focus their diodes’ light down onto the canopy for deeper penetration, while the 120 degree lenses spread their light out more for a larger coverage area. Overall, the coverage when flowering is around 1.5 by 1.5 feet and you can stretch it to 2 by 2. For vegging you can back the light off a bit and get a coverage area of 3 by 3 feet.

The light uses sixty 5w chips. 5 watt chips are more powerful and give you deeper penetration, but they also emit more heat. With 2 fans for cooling, this light is able to deal with that. It maintains a low working temperature which gives it a longer lifespan. It is rated for 50,000 to 100,000 hours of use. One negative: the fans are a bit noisy.

Galaxyhydro 300 Watt 9-Band LED Hydroponic Grow Light

As the name might suggest, the Galaxy Hydro 300 Watt 9-Band Indoor Grow Light emits 9 different wavelengths, for a full-spectrum light that works during any stage of plant growth and is especially well-suited for the flowering stage, which is a weakness of most LEDs in this price range.

The wavelengths and amount of each are: 78 diodes at 630 nm (red), 8 at 660 nm (dark red), 8 at 470 nm (blue), 2 at 450 nm  (dark blue), 1 at 430 nm (UV),  1 at 740 nm (IR) and 2 white diodes.

The white light ensures your plants still get some light in the green and yellow wavelengths, but only a little. They don;t use much. Mostly they want red light and blue light, but especially a lot of red for the all-important flowering stage. The UV and IR diodes further help increase bud quality during flowering.

This fixture has a Zener, which works as a capacitor and ensures that, should one diode fail, none of the others are affected. So if a diode goes out, the remaining diodes will continue to function normally.

Galaxy Hydro outfitted this light with 3 watt LEDs and a mix of 90 degree and 120 degree lenses. The 90 degree lenses focus the light into a tighter beam for deeper coverage, while the 120 degree lenses give you a wider beam for a better light spread. Using a mix of lenses gives you the best of both worlds.

This light uses 135 watts, but is equivalent to a 250 watt HID system. It gives you a coverage area of 2 by 2 feet during flowering and 3 by 3 feet during vegging. It has a rated lifespan of 50,000 hours. It is backed by a 2-year warranty and comes with a 30-day money-back guarantee.

MEIZHI 300 Watt LED Grow Light

The Meizhi 300 watt LED plant light uses sixty 5 watt Epistar chips. It has red light between 450 and 475 nm, blue light from 620 to 630 nm and 650 to 660 nm and 5500 to 6500K white light. This combines to give you the full spectrum of light in a ratio that is perfect for any stage of growth and that can actually flower a plant.

This light is equivalent to a 250 watt HID system, but only uses around 130 watts of power. Since a 250w HID system actually uses more than 250 watts (the ballast also consumes electricity), you save more than half on your electric bill. And that’s without considering the heat.

Two high-quality aluminum heat sinks and high-speed cooling fans keep the light running very cool. And surprisingly, the fans do not give off much noise (56 db). The light also has two isolated power supplies. The low working temperature and the dual power supplies combine to ensure a long lifespan of 50,000 to 100,000 hours.

The Meizhi 300 can cover an area of 1.5 by 1.5 for flowering. You’ll need to hang it 12 to 24 inches from the canopy. It gives you a PAR value of 300 umol at 18 inches height. If you measure the lumen, you get 5911.

The light ships with a power cord and a free hanging kit. If you are unhappy with it, you can return it for free within 30 days of purchase. You can get it repaired for free within 3 months. After that, you get free accessories, but have to pay for maintenance service for the first year.
