The VIPARSPECTRA V300 has been the number one best seller among grow lights, so we reviewed it to find out why it is so popular. We’re always on the lookout for good products to recommend.
First off, this is a basic LED light panel that’s good for beginning growers who are starting out small. Its light covers 2 feet by 2 feet for optimal growth, and it really does penetrate down into the canopy. The panel contains a mix of 5-watt LEDs that put out a full spectrum of light, from infrared to ultraviolet. Let’s take a closer look at all of this.
The far ends of the spectrum are invisible to the human eye, so that’s why some of the LEDs don’t look like they are lit. That doesn’t mean it’s safe to look at the panel when it’s turned on. Use protection like the Method Seven Grow Room Glasses. That way you don’t damage your eyes, and you can inspect your plants without turning off your panel or needing a different light.
Why are LEDs a good idea for growing plants indoors? For one, they use less electricity to put out a lot of light. They create less heat so you don’t need extra fans to cool down your grow tent. Both of these factors mean you save money on your power bill and (hopefully) don’t draw the unwanted attention of authorities.
Growers in the past used HPS/HID lights. Those abbreviations mean “high pressure sodium/high intensity discharge.” That kind of lamp needed an additional component called ballast to keep their light output from flickering too much. They put out a lot of heat and suck up a lot of electricity.
VIPARSPECTRA created the V300 to replace a 250-watt HPS/HID light. Their LED panel doesn’t run hot or burn your plants. The heat it does generate is controlled by large fans and heat sinks built into it already, and it doesn’t need a ballast.
While it’s rated for 300-watts output, it only consumes 136 watts of energy. That’s less than running three 60-watt incandescent bulbs (not like you can find those for sale anymore).
The 5-watt LED bulbs that VIPARSPECTRA uses come from well-known companies like Bridgelux and Epileds that have good reputations. VIPARSPECTRA has the LEDs mounted at a 90-degree angle pointing straight down at your plants.
When they mention lumens and PAR, they’re talking about the intensity of the light emitted by the V300 panel. Lumens are for humans, so don’t try to measure the quality of your light by how bright it would be to your eyes. What matters is PAR, which is a measurement of the intensity and coverage of the light.
The PAR of the V300 was mapped out with the panel hung two feet above the canopy of the plants. The best coverage for vegetation and flowering is limited to just 2 by 2 feet although the light does reach out to 3 by 3 feet. Since flowering needs a lot of light, don’t try to crowd in too many plants.
VIPARSPECTRA offers a 3-year warranty and a 30-day satisfaction guarantee so you can try it out to see how your plants grow. On the upside, if you love the V300, you’ll be glad to know that LEDs can last between 50,000 and 100,000 hours before they burn out. Since 100,000 hours is about 11 years, you’ll probably upgrade this light before you need a new one.
Some other useful details about the VIPARSPECTRA 300-watt LED grow light:
- Weighs 5.6 pounds, measures 12.6 inches long by 7.9 inches wide by 3 inches thick
- Comes with hanging kit and 6-foot power cord
- Accepts 50-60Hz, 100-240V AC
- 60 LEDs total
- VIPARSPECTRA is a trademark of the Shenzen Bailuo Technology Company, Ltd.
Is this light capable of running 24 hours a day without problems???
Absolutely! Just finished my Veg cycle (I always do 24 not 18) & ran it throughout with no problems. And my girls are loving the full spectrum.
How do these compare to a brand like MarsHydro?
How did you flower cycle go with this light? I’m having issues and curious if bloom light was needed to add with this to aide in this cycle?
This light has insufficient red spectrum to be used as a primary light during flower cycle. Flower can be achieved but yield will be low. I use these lights in combination with HPS for an outcome that is better than HPS alone. Also work well in a small place combined with 2700k CFL’S
I just ordered 2 300w lights and I was wondering the distance I should keep the light from my plants throughout the growth cycle. For example: from seedling to veg to flower.
roughly 20 inches away, no closer then 18 inches. It WILL burn your plants. They will look off colored like they are bleached.
It’s in the instructions – about 40-50 inches for seedlings. If you followed Jake’s advice you either got a mega crop of seedlings or fried them fast.
Hi I would like to plant bushes 10, to a number of 300-watt LED panel I need or that you think of what model I use a few watts LED panel. Thank you
Hi Reza,
For ten plants, we’d say at least 3 x 300W panels, depending on how you arrange the pots. These VIPARSPECTRA panels would work, or you could go with a Advanced Platinum Series P900.

I have switched my light cycle to 12/12.. Made sure all my light leaks were sealed up.. I have my lights turn on during the night and the lights off during the day.. However, I am NOT seeing any flower growth and stretching seems to be slowing.. It has been 3½weeks.. Do I need to add a red bloom light with the full spectrum led? The 300w full spectrum has a white light output.. I have a couple other small light socket model led lights that put out straight purple and had no issues in growing with that. This is 1st attempt with 300w led fukk spectrum and goin crazy, any help is greatly appreciated.. Tia!! #desperate..
Hi D,
How did it work out?
Hi I have now bought 3 VIPERSPECTRA 450 Led.
I have 2 White Widow xBig Bud Autos under it with extraction and both are doing great.
The switches veg n bloom ! At the beginning from seed just use the veg light for about 1 week then you can include both lights!
Flowering started just a few days after week 4 and the other 2 450s I’ve bought are for 9 plants
They work well with. Anna is so far and I have flowering so it’s going well
What is the distence of the light at the first week
During flower did you have both lights on? Or just the flower? Just got my 900 vipar spectra for 3 x 4 grow cabinet.
can a 450 handel 2 plants
You don’t size your lights to the plant but to your Grow area.
A 450 is solid for 2×2 area.
I run three 300’s in a 2×3. Two for Veg then add a third for flower. I average 3 ounces/plant.
I grow 2 plants will one 300 watt in a 3ft room be good enough
No. Get a 600 for that area or at least two 300’s
So, euh, saying its the PAR that matters, what is the outcome ?
What did the measurements say, in figures ?
Hi. I got a modelv300 and I want to use it but the cord is too short. Help me please because I don’t want to send it back.
EVER HURD OF EXTENTION CORDS LOL
so I just bought 300w like got everything setup and currently germinating 2 but the one i planted already its first to leaves didnt live long the fell out im trying to revive it but so far no good im a new grower contact me with any help or even better i can send a picture of my setup and we can discuss on the issues. really means alot.
My 300w has fake CE & RoHS label spelt RoSH.
Viparspectra have refused to provide the certificates to confirm there compliance.
They are not compliant lights.
Resale of these lights in the EU or UK are illegal without valid certification.
Its the resellers responsibility to make sure that they are certified.
Boo hoo
Was thinking of getting a 900 for a 3×4 foot print, thoughts?
I would use a 400w hps with the 300w led
I got 9 in a 12×12 bd..they work great..on my 4th grow
How would this light help out a strong CFL grow?
Hello,
Would this light be enough for a 3ft x 3ft x 6ft tent holding 3 to 4 plants? Or do you think the 450W version would do bettter? Thanks!
At least a 600 for that space
Hello everyone.
First time planter. I want to grow 2 hydroponic plants for my wife who has a medical Marijuana card. I am thinking of getting:
VIPARSPECTRA 300
2*2 tent.
Air pump w/ 2 air stones
Nutritions
Do i need anything else?
How far should i keep the light from plants throughout each stage?
Do I need to change light during different stages?
REAL NOOB IN PLANTING
Thanks in advance.
Get a 600 for that space. Keep it 24″ away.
Only one plant in that space.
Got the 900 for my 3×4 footprint! Wifey through out my directions! Veg light for veg… both for flower? Or do I flip it to just flower? Wish the directions were online
Veg for Veg. Both for flower.
