Best LED Grow Lights for Every Budget
Our Comparison Tables
Below this comparison table, you’ll find full reviews for award winners, bestsellers, budget options, quantum boards, supplemental lights, lights for small spaces or large grow rooms, as well as the lights most favored by our readers—in other words, the lights other growers like you are already using to get results. The row labeled “Covers/HPS Equiv/Draws” shows the manufacturer’s info about coverage area, HPS lamp watt-equivalent, and actual power draw. This information is approximate, since every growing situation is different.
We selected our list of best LED grow lights for every budget based on the results they showed and features they offer. We have also taken into account factors like customer reviews, industry awards and a close look at which lights have proven most popular with our readers. And we’ve tried to keep our choices within the budget of the average home grower.
We’ve covered a lot of lights below. The first three are our Editor’s Choices but that does not mean you should ignore the rest of the lights we have covered.
Now, here’s our top pick for 2019…
Best Overall LED Grow Light
- PlatinumLED lights have the highest PAR/lumen output per watt of any LED grow light! 2x-3x the intensity of any other lights!
- Complete 12-band full Spectrum including UV/IR + 2x 10W Cree xm-l2 LEDs per cluster - 38% higher output than older XML models!
- Selectable veg/flower/boost switches plus all new proprietary one piece integrated 90/120 Degree high distribution focusing lens system
- 600W HPS replacement with 3x3 bloom or 4x4 veg coverage at 18" Height - perfect for compact applications or using multiple units for coverage
- Complete 5 Year Warranty plus our exclusive 90 day satisfaction or return guarantee***
In previous years, our overall Editor’s Choice went to PlatinumLED’s Platinum Series P300, 300W. We still love it, it’s a great light. But for 2019 we’re going with the Advanced Platinum Series P4-XML2 instead. For two reasons:
- Once again, the makers have outdone themselves with their new lighting system. As with last year’s improvement you can’t go wrong with it but if you’re after the best on the market you really need to choose this.
- A majority of our readers do smaller grows (600W HID equivalent or below). This is why we went for this compact light. You can go for larger models from this series or just expand your grow with by adding more units.
OK then. What’s so great about the Advanced Platinum Series P4-XML2?
This unit can comfortably cover a maximum grow space of 4′ x 4′, with core coverage of 3′ x 3′—or 12 to 16 plants. This is more than enough for home growers in most U.S. states.
PAR is the highest for any other LED grow light.
- The sheer quality of the LEDs themselves: American-made 10W CREE XML single chip diodes combined with 3W Bridgelux blue and white diodes. The wavelengths produced are 100% usable by chlorophyll. This is a serious improvement on the product we reviewed as the best last year.
- US made, high intensity LED drivers to maximise output
- A fully programmable system for all stages of growth from seedling to flower.
- An advanced lens focusing system over the 4 arrays that includes a 120 degree convex lens over the CREE diodes to optimize light performance
- A 12 wavelength spectrum from low frequency UV to high IR, to give your cannabis every kind of light it needs for big yields and dense, potent, flavorful buds.
- Three light settings for vegetative, flowering and a boost mode that can be used while you work on the grow.
- Rated at 93 watts for vegetative stage and 180 watts for flowering, this is a very efficient grow lamp. It replaces a 600W HPS system
- Has a 3’X3′ coverage for core bloom stage and a 4’X4′ coverage for veg stage, penetrating up to 18 inches
- 5-Year Warranty, 90-day Money Back Guarantee, hassle-free returns
- US Sales and Support staff
- Well worth the money, but look elsewhere if you’re on a tight budget.
- If you want a fully programmable/customizable spectrum, this isn’t for you. (Keep reading for our recommendations.)
If the price makes you wince, this is because it is the top end of Advanced Platinum’s range. For just over half the price you can always purchase the Advanced Platinum Series P300 300w 12-band LED Grow Light that we rated as the best light last year.
The Advanced Platinum system replaces a 400W HPS system – smaller than the P4-XML2 but is widely held as one of the best on the market today for a smaller grow.
Best Budget LED Grow Light
- HIGHER YIELD: Updated MARS ECO 300W light made with newest SMD leds which can get 30% higher PAR than old led. Full spectrum light perfect for all plants at all stages.
- ENERGY-SAVING: Consuming only 120watt10% with the same effect of typical 150W hps or HID grow lights. Enough for 2 X 2 growing area. Using 4 Mars 300 watt led grow lights will be perfect for a 4 X 4 cu. ft. area.

The MarsHydro ECO 300W is very much one of Mars’ basic, entry-level full spectrum lights—but a very decent budget option. It’s the successor to MarsHydro’s top-selling Mars 300W, which Mars is now slowly phasing out.
And as you’d expect, it’s even better.
What’s so great about it?
- High-intensity 5W Epistar LEDs are better than you’ll get in some similarly priced lights.
- Coverage is respectable: 2′ x 2′, or enough for two big plants.
- Replaces a 150W HID light.
- Low power draw: only around 116W (even more efficient than the old model!).
- Max. Yield: 1.0g per watt.
- Now daisy-chainable (another upgrade on the old model).
- Quieter and runs cooler than the old model.
- Suitable for the whole grow—plenty of both blue and red wavelengths in the spectrum.
- Although the lights are made in China, there’s a service center in California and US and European warehouses to ensure quick shipping.
- 3-year warranty.
- Well under $100.
- No UV or IR wavelengths in the spectrum
- No veg/bloom switch or dimmers
- Hanger not adjustable—but you can buy the adjustable one here MARS HYDRO 1/8 Inch Heavy Duty Adjustable Rope Hanger Fully Locking for LED Grow Light
This light has been a very popular choice among our readers, hence our recommendation.
But if you’ve got the budget, also consider one of MarsHydro’s newer models in the Reflector Series or Pro II Series. You’ll get brighter, more even coverage and separate veg and bloom switches—not quite as cheap, but still at a very affordable price.
Also available in higher watt versions: MARS HYDRO 300W 600W LED Grow Light Full Spectrum for Indoor Plants Veg and Flower Hydroponic with Thermometer Hygrometer Hanger Growing Daisy Chain and Switch Cool and Quiet (ECO 300W)
Alternatives: Viparspectra VT300; Roleadro GalaxyHydro 300W
Most Efficient LED Grow Light
- Upgraded INVENTRONICS Power Supply - 480W power draw (dimmable to 240W), 1000W SE HID replacement.
- Flower Footprint: 4' x 4' to 4.5' x 4.5', Veg Footprint: 6' x 6'
- Each HLG-550 V2 uses 4 of our custom designed full-spectrum high efficiency white light quantum boards with Samsung LM301B and Deep Red LED 660nm for enhanced flowering.
- PPF: 1257 umol/s; PAR efficacy: 2.6 umol/j ; Reliable passive-cooled design & ETL certified
- We believe in the quality of our products and include a 3-Year Warranty from date of purchase!
This is the replacement for the HLG 550 3000K. As with its predecessor, testament to the quality, affordability and popularity of HLG’s quantum boards is just how often they sell out. So if the light you want’s not in stock, sorry, you may just have to wait a bit—but by all accounts, it’ll be worth it!
Why? Because the HLG 550 V2 is the most efficient LED grow light to cover a 4.5’ x 4.5’ area! Or 6’ x 6’ for veg. With full-spectrum white light.
Thanks to clever design and the highest quality components, the efficiency is 2.5 umols of PAR per joule. So it’s replacing a 1000W HID light while drawing just 480W at the wall.
- Surprisingly affordable—even pre-assembled quantum board lights like this one compare very favorably for price with similar power lights from the top manufacturers.
- Ultra-efficient: 2.5 umols of PAR per joule.
- Excellent penetration and very even coverage, due to…
- 1152 top bin Samsung LM301B LEDs packed into an area 26” x 20”
- Passive cooling, so no noisy fans.
- High efficiency Mean Well dimmable driver (dimmable up to 50%).
- Lower than average recommended mounting heights—just 22 – 32”. Meaning plenty of those photons hitting your plants at every grow stage.
- See your plants in their natural colors, thanks to full-spectrum white light.
- 3-year manufacturer warranty.
- Designed and manufactured in the USA.
- Super-helpful customer service.
- Not programmable.
- No built-in timers.
The HLG 550 V2 is available in 3000K or 4000K models. The spectrum of the latter has more blue in it, plus a bit more green and yellow. While the 4000K has a little more red and orange than the 3000K option.
Best COB LED Grow Light
- 405W CREE COB LED Grow Light with 3000k warm white & 5000k cool white COBs.
- Optic 4 uses USA Made ultra efficient CREE COBs LEDs that will give you unprecedented light penetration and massive yields
- Flowers a 3' x 3' area or 3.3' x 3.3' area max with up to 1.62 lbs per harvest!
- Full Spectrum White light LED technology from the CREE COBs illuminates your Canopy in its natural colors
- Industry best return on investment with proven high yields and commercial level PAR Output
Like quantum boards, COB (Chip On Board) lights are super-efficient and give you brilliant light penetration. Both also produce full-spectrum, natural-looking white light. The main difference is the way the diodes are spread across the unit—loosely speaking, a quantum board is like a COB light but with the diodes spread out. Optic’s COB lights boast genuine USA-made CREE XLAMP CXB2540 80W chips to give you coverage of 4′ x 4′ for flowering.
- Powerful and efficient: yields of up to 1.8g per watt—1.62 lbs per harvest.
- Commercial level PAR output at an accessible price—1250 u/mols at center of footprint when hung at 24″.
- Equivalent to a 600W HPS light but consumes only 405W at max power.
- Bloom boost switch for flowering—turns on 64 Epistar and Bridgelux 5W LEDs.
- White light, full spectrum output designed for cannabis—including UV and IR.
- See your plants in their natural colors.
- Built-in timer.
- 5-year warranty.
- “Industry best Return on Investment”, according to manufacturer.
- Not as programmable as some similarly priced lights.
- Not dimmable.
- Quantum boards are better for short grow spaces—they can usually be hung closer to the plants.The Optic 6 should be plenty large enough for many home growers. However, for bigger or smaller grows, Optic LED COB lights also come in a range of different sizes—all of them boasting pro-quality CREE diodes at a relatively accessible price.
We favor quantum boards over COBs, just slightly. But there’s really nothing much in it. Both give even coverage, excellent penetration and enviable yield per watt. So just go for whichever best suits your grow space. Either way, you’ll not be disappointed!
Best LED Grow Light Under $200
- Lens TechnologyBESTVA Full Spectrum LED 1200w Grow Light combines optical lens technology. 90 degrees lighting angle is much better than the current market plant lights with 140 degree lighting angle, reduce light waste and maximum penetration to increase light by 30% with higher PAR values than any other brand. It crucial for canopy penetration to nourish lower leaves and flowers.
- VEG & BLOOM SwitchTwo Seperately Switches: VEG for seeding growth. BLOOM for flower and fruit, adjust luminous intensity and spectrum by the switch of VEG or BLOOM. VEG/BLOOM features a more red/blue heavy output to deliver maximum performance from seeding through final flower.
- Newest Cooling SystemWe use 5mm thickness integral aluminum structure radiator instead of multiple dispersed radiators for better heat dissipation. The integral aluminum structure radiator is in the middle part of the led light, part of you can see it and the entire aluminum radiator that can't be seen is above the light board inside the luminaire. It cooling better and stronger.
- Core Coverage AreaCompare to 1000 watt HPS while consuming only 257.6 watts! Twice effective coverage area than any Reflector Series lights, perfect for a 3.8' x 4.3' growing area at 24" height. Avoid Daisy Chain, Dangerous First & Energy overlap causes waste.
- 3 years warrantyPlus 90 days satisfaction or return guarantee. We are so confident in our products' quality control, if any question pls contact us directly, we will offer you professional guidance to help your plants grow better.
Like MarsHydro and Viparspectra, BESTVA aims to create “well designed, well made fixtures at reasonable prices and no unnecessary extras” (BESTVA stands for best value). Unlike some budget brands, they’ve also been in the business a similar length of time to Mars and Vipar—around 8 years now—so we’re happy to recommend one of their lights here. This one’s a big seller on Amazon too. Probably because you get a lot of power for not a lot of cash—PAR at the center of the footprint is 1221 umols/m²s (hung at 24″).
- Footprint of 4′ x 5.2′ when hung at 24″.
- Replaces an 800W HPS/MH light but draws only 280W.
- 60 dual-chip 10W Bridgelux and Epiled diodes.
- Separate Bloom and Veg switches—saves money during the veg stage.
- Passive cooling, so no extra moving parts that could fail.
- Lifespan of 100,000 hours.
- 3-year warranty and good reputation for customer service.
- We prefer dimmers to Bloom/Veg switches that just turn diodes on/off rather than dim their intensity. Genuine dimmers can help with a smooth, gradual transition into flowering (higher intensity light) that minimizes shock to your plants.
- Even if you shouldn’t expect average PAR across the footprint to be as good as the specs at the center, this is still an excellent light for the money. The customer reviews on Amazon and BESTVA’s own site are generally pretty glowing too.
Best LED Grow Light Under $500
- POWERFUL: MARSHYDRO PROII series LED Grow Light produce more red and blue PAR per watt to realize more yield, higher quality and lower operating costs with horticultures most powerful lighting system.

High quality CREE diodes and excellent PAR figures at a very affordable price: what’s not to like? There’s also a cheaper strand to the Mars Pro II series lights, with Epistar LEDs instead. And they’re great lights too… but CREEs are worth the extra few bucks.
And those CREE diodes are exactly what give these lights such impressive numbers: 1400 umols of PAR (hung at 18″), flowering coverage of 2′ x 4′ and veg coverage of 3.5′ x 6.5′ and a max. draw at the wall of just 355W.
- Max. yield of 1.8g per watt—great value for money.
- Replaces a 400-600W HPS/MH light, for a fraction of the energy costs.

You can get more information on how to get started growing cannabis indoors from our free e-book (get it in the sidebar on the right), and from our regular reviews of the best grow tents, best nutrients and other top tools and equipment for your growing operation.
Get bigger, better buds faster!
For germination, the light should be about 30 inches above the plants. For vegetation phase, lower the light to about 24 inches above the plant top. For flowering phase, lower the light even further to about 18 inches. As you lower the light, the light’s footprint grows smaller. This means that plants on the outside of the footprint might not be getting optimal light energy and you may need to add an additional light.
Yes and in fact with current models of LED Grow lights, you can expect a better result than with older High Intensity Discharge (HID) or fluorescent lights. This assumes that the LED Grow Light you buy gives sufficient energy for your plants.
Generally, 30-50 watts per square foot is sufficient. Some growers recommend a higher level of 65 watts per square foot. Higher than 65 watts risks burning your plants. Remember that with LED Grow Lights, the wattage specification should be the manufacturer’s estimate of the actual watt output of the LED lights, not the power draw at the wall and not the wattage the manufacturer states for an equivalent HID light.
Yes, you can get eye damage from LED Grow Lights and any bright light, particularly in a closed space like a grow tent with reflective interior. Just like looking at the sun. You should always wear good-quality protective sunglasses with good coverage of your field of vision.
Probably the easiest way to build your own LED Grow Light is to buy a kit from HLG. The kit will contain the parts necessary to build a Quantum Board LED light. Kits come in various power output sizes. While the kit has clear instructions and the customer service of HLG is very good, bear in mind that building your own light may cost nearly as much as buying a light already assembled.
Size of grow light refers both to the physical size and the energy output of the light. Once you have calculated the energy output of the light for your number of plants, you need to choose a light with the right physical size and configuration. If you grow plants in a row, then you will want a long thin light. If you grow your plants in a square, you will want a light with a square shape. To calculate the energy output you need, use this calculator:
