Unlike older design LED abound lights, yous don't need to worry about changing the light modes when your cannabis changes growth phases. The HLG 650R utilizes a complete white spectrum perfect for all phases of growth.
Take a await at the image above and tell me you've seen a spectrum that perfect earlier. You'll be hard pressed.

#5. Green Sunshine Co. Electrical Sky ES300 Grow Light – Best Mid-Price Abound Light
Looking for the best of both worlds with a grow light? I've got a solution for you. The Electric Heaven ES300 isn't the most expensive grow light, simply with a little flex in your budget it'll give you lot a lot of the same loftier performance.
The Green Sunshine Company is a small abound calorie-free company, simply the grow lights are very skillful. What makes the Electrical Sky ES300 one of the all-time LED grow lights in the mid-price range?
Information technology's a combination of the most important factors similar spectrum, light intensity (PPFD), and coverage ability.
So, without wasting more fourth dimension, permit'south take an in-depth await into this console.
Build:

It's quite efficient, emitting ii.0 uMol/Joule of power, and just utilizing 300 watts from your wall outlet.
This low-cal is plug and play. Unbox information technology, hang with the easy hang kit, and turn it on.
Spectrum, PPFD and Coverage:
The Green Sunshine Company custom designed the spectrum for this abound light. They call it a wideband spectrum. The colour breakdown is as follows: Approximately 10% blue, 25% green, 55% red, and 10% infrared.
So it differs in that it has less blue, more dark-green and it'south heavy on infrared. Infrared signals tells your plant to grow short stocky stems and too helps the plant abound into specific shapes.
Unique spectrum doesn't mean bad. There are dozens of owners who swear past the light if you lot check out the reviews on LED Abound Lights Depot.
A study also showed that some green light was benign for cannabis growth, peradventure not ironically, it's the exact amount of greenish spectrum that's in the ES300 spectrum:
A low percentage (≤ 24%) of green lite enhanced plant growth, whereas constitute growth was inhibited under a higher percentage of green lite (Kim et al., 2004a, 2005; Folta and Maruhnich, 2007; Lee et al., 2011; Liu et al., 2017).¹
The importance of PPFD is ensuring your lite emits a minimum of 462 uMol and a maximum of 925 uMol based on a daily light requirement of 20-40 moles. If yous want to larn more specifics, you can read more most that in my article here.
Taking a look at light intensity, from 18″ height the Electric Sky ES300 emits around 980 uMol. In short, information technology meets that daily light requirement standard perfectly.
Y'all can get an effective coverage of two'x4′ out of this grow lite. Merely what's not bad nearly the ES300's coverage, is the light remains intense even at the edges of the coverage area. The potent intensity makes the Greenish Sunshine ES300 the best LED grow light for a 2x4 human foot space, in my opinion.
There are plenty of nifty lights out there, just nearly of the high performers are designed for 4x4 or larger. If y'all're merely growing 2 plants in a 2x4 but y'all still want a high performing LED grow calorie-free, the ES300 is the perfect fit, hands downwards.
Lower quality grow lights tend to drop below usable intensity earlier fifty-fifty reaching the edge of the manufacturer'south claimed coverage area. So that's why you take to keep your eyes peeled – simply luckily that's non the instance with the Electric Sky ES300.

Another competitor to Spider Farmer would be HLG (Horticulture Lighting Group). HLG uses the same brand LEDs and driver as Spider Farmer, and their lights are priced slightly higher.
One important divergence is that HLG offers different spectrums on their lights, which may be more preferable for some people. For example the new HLG 550 Eco Series offers 3000K (heavy red) and 4000K (heavy blueish). The B-Spec and R-Spec editions are in the middle with 3500K and cost slightly more.
Intensity (PPFD) & Spectrum:
As you can see above, the Spider Farmer SF-4000 will light a 5x5 grow tent pretty well. Intensity in the 3x3 pes range is 900 to 1300 micromoles, great for flowering, but probably a bit much for veg. So during the vegetative phase you may need to heighten thet lite or dim it, whichever is easier.
The ideal intensity for veg is roughly 300 to 600 micromoles, and for flowering y'all desire to be in the 460 to 900+ micromole range. You can go over 900 micromoles in flowering but it'due south not actually necessary.
The spectrum on the Spider Farmer SF-4000 is a mix of 3000K, 5000K, 660nm and infrared spectrums. This is a very dainty mix of lite that'll grow cannabis through all phases.
Ability Consumption & Cooling:
You'll be pulling 450 watts from your wall when using this grow calorie-free. The commuter is dimmable, then if you lot choose to dim you'll use less electricity.
All grow lights generate heat, and the newer quantum style lights similar this one don't characteristic fans. So be prepared to install an inline fan and aquiver fan in your grow tent.

Features:
The HLG 225 consumes 225 watts of power, and has a pretty unique blueprint with large metallic heat sinks on the acme side of the grow calorie-free. Speaking of estrus sinks, I definitely wouldn't worry well-nigh oestrus with a 225 watt grow light, but if you lot utilize several of these units in one space, the heat sinks may come in handy.
The LumiLED and Luminus LEDs are centralized onto one middle lath, and are surrounded past a white cup reflector.
While the HLG 225 isn't the cheapest it's a loftier quality low toll option for a pocket-sized space.
Spectrum:
As yous can run across from the epitome to a higher place the HLG 225 provides a full spectrum capable of growing from seedling to harvest.
More specifically, the LEDs are a combination of white 4000K, 630nm red and 660nm red.
Hang Peak & Coverage:
Vegetative phase hang meridian: 24 inches
Flowering phase hang height: eighteen inches
This grow calorie-free will flower up to 3x3 feet and veg up to 4x4 feet. The HLG 225 intensity goes to about 500 in the middle and near 300 on the sides of a 3x3 ft grow tent when hanging 24 inches above the plants. That'south a proficient intenisty level for vegging.
If you hang the lite a little bit lower at xviii inches, the intensity gets upwardly to 900 ppfd in the center and 450 ppfd on the edges of a 3x3 human foot grow tent. That amount of intensity is adept for flowering.
Verified owners of this grow lite have had very positive things to say: "no complaints… no estrus…the girls Honey it," "piffling but powerful" and "awesome abound light for my small tent".

(Click Here to View or Buy the P1500 at LED Grow Lights Depot)
Hither's another great LED abound calorie-free in my best LED grow calorie-free heir-apparent's guide. Information technology's the Viparspectra P1500 from the Viparpsectra Pro Series. Viparspectra fabricated the Pro Series every bit the next generation to their previous imperial spectrum abound lights.
I actually purchased the slightly smaller P1000 and tested it out, you can read virtually that here.
The Pro Series are peachy upkeep grow lights for smaller size spaces. Viparspectra has a very dedicated following of growers who swear past these grow lights.
Features:
The Viparspectra P1500 Grow Light is a 150 watt grow calorie-free with the most modern white and red LED spectrum. The white spectrum is slightly better than purple spectrum in tests, and that'south why all manufacturers are using white spectrum now.
The P1500 and the rest of the Viparspectra Pro Series nonetheless have a oestrus sink on the height side of the grow light, which isn't necessary simply information technology's nice because all the other breakthrough board style lights seemingly abandoned heat sinks even though the higher powered models however generate some heat.
The Pro Series abound lights are dimmable from 0% to 100% with an like shooting fish in a barrel dim knob on the side of the light.
PPFD & Spectrum:
The smaller Viparspectra Pro Series models like the P1000 and P1500 are pretty low power at 100 and 150 watts. Then y'all can hang these grow lights close to the canopy and save some overhead space at the same time.
At 12 inches you can get a proficient flowering level intensity, and perfect veg intensity at fourteen inches.
Coverage:
Based on my personal experience with my P1000 I would say the P1500 is good for 2x3 anxiety of coverage. If you have a larger sized grow space, you can purchase multiple units, or even purchase a larger size because the Pro Serial goes from P1000 to P2500.
How many Viparspectra Pro Series grow lights do you need for a 4x4 grow tent?
Based on my estimations I would recommend two P2500 models for a 4x4 grow tent.

#12. Phlizon 1000w COB LED Grow Light:
Phlizon is some other well known LED abound lite manufacturer. You may know them from their other inexpensive LED grow low-cal models. The Phlizon CREE COB serial seen in a higher place is i of the best LED abound lights for the price. This is the 1000 watt model, merely they're produced in variants upwards to 3000 watts of output.
Ane unusual feature on a high output light similar this is the daisy chain capability. Typically that characteristic only comes on lower output lights as you can only run so much current through the daisy chain outlet. But with this light you'll have that daisy concatenation option.
PPFD and Coverage Area:
At 24″ hang height you'll go a good coverage for a 2x2 area as shown above.
You lot can try lowering the calorie-free to xviii-20 inches and get a bit more intensity in that 2x2 area and completely sacrifice that space beyond 2x2 which is useless anyway because that intensity is besides depression.
The Phlizon 1000w COB is the best LED grow light in the Phlizon COB lineup, because in one case yous consider that intense 2x2 coverage area, you lot can become 2 of these units for less than the 3000 watt model, and get a larger effective coverage space than the 3000 watt model.
How many Phlizon 1000w COB grow lights do y'all need for a 4x4 grow tent?
Due to the 1000w being the smallest of the Phlizon COB lineup, the constructive coverage is 2x2, but it's intense light inside that 2x2 surface area. Based on my estimations, you'd need ii of the 1000w models for a 4x4 grow tent.
For Maximum Cannabis Yield: ii Phlizon 1000w COB grow lights.
Spectrum:
The Phlizon 1000w COB provides a total spectrum of absorbable light to your plants. It includes 630-660nm, 470nm, 6500k, 3000K, ultraviolet (UV), and infrared (IR).
The ultraviolet has been shown to increase THC levels, and infrared benefits plant formation equally well every bit flower quality. These are two actually important wavelengths for good quality cannabis.
Cooling & Heat Dissipation:
Two large cooling fans with heat sink help keep this light running absurd. One user who uploaded a video of his Phlizon 1000w said it runs absurd. Other owners who've reviewed this light also said heat was not an event.
Phlizon 1000w COB Specifications:

#thirteen. Sansi 36w Grow Low-cal– Perfectly Crafted For Modest Plants
The Sansi LED 36 watt grow low-cal seedling is a full white spectrum LED abound lite. It's a great grow low-cal for small spaces, a neat abound lite for pocket-sized plants, and a dandy abound light for succulents.
My Fourth dimension with the Sansi 36w Abound Light:
Sansi was kind enough to transport me one to feel first hand:
This abound light is perfect for the pocket-sized space in my firm where I grow a few succulents.
I already had a cheap 12w grow light with a red/blueish spectrum, and the succulents weren't responding to that grow light. The succulents weren't dying but they weren't thriving either.
The difference in the succulents afterwards the first 1-2 days of installing the Sansi 36w grow light bulb was impressive. The succulents with leaves sort of "lifted upward" like they were standing at attention, or as if they were awoken.
I continued to notice faster than normal growth in my succulents over the post-obit month. It'south clear to me the Sansi 36w LED Grow Light bulb made a deviation to those succulents.
If you know much nearly succulents you know they're amongst the to the lowest degree enervating plants. And then I picked a small plant from my yard to see if I could grow information technology successfully under the Sansi 36W LED grow light. I ended upwards with a Marigold seedling.
Marigolds are a bit more than demanding than succulents. They look a lot of light and a lot of water to sustain their rapid growth. They go from seedling to flower in 40-50 days.
After ~30 days the marigold is doing very well nether the Sansi 36w grow light bulb. I've kept it in a small abound cup to save space, but considering the environment it'southward been given, the blossom is doing very well.
I kept the Sansi bulb xviii″ above at all times, and run the lite for 8 to nine hours per day.
Update: I transferred the marigold to a larger bucket and it continued growing and bloomed beautifully under the Sansi bulb:
Why the Sansi 36w grow light bulb performs well:
This is a keen abound light for minor plants, or even if you desire to combine it with other grow lights to boost light intensity.
The spectrum of this grow light really separates it from other depression wattage grow lights:
No affair what size plants you're growing or what size grow infinite you take, spectrum is one of the well-nigh of import features in a grow low-cal. White spectrum has been shown to result in 12-16% higher tomato yields compared to red/blue spectrum alone (you can read more about white spectrum here).
Most of the small grow light bulbs on the market today still feature red and blue spectrum, so the Sansi 36w Abound Light bulb provides you an reward on that front. If you read any of my reviews near larger grow lights for cannabis, yous'll come across I always prefer the white spectrum over red and blue alone.
Some other nice feature on the Sansi 36w LED grow lite is the 120 degree lens. That lens helps spread the light out more evenly beyond the plant canopy, instead of focusing the light all in one direction, which can result in burned leaves.
