Viparspectra PAR1200 LED Grow Light – Everything To Know
Viparspectra is one of the best selling brands on the LED grow light market. The PAR1200 1200 watt variant is the highest power model currently offered by Viparspectra.
*Update: Viparspectra Has Released a New Version Grow Light Called the Pro Series -- Read About Them Here*
In this review we’ll take a look at this model’s specific features and how it stacks up against some comparable LED grow lights.
Viparspectra Brief Brand Overview:
When you’re investing in a grow light expected to last you 50,000 hours of use or longer, you want to make sure it’s coming from a company that cares about quality. Because ultimately when you expand your grow space, or help a friend with theirs, you’ll want to know where you can turn.
Viparspectra is one of the top LED grow light sellers on Amazon, and they didn’t get there from making bad product or providing bad service.
They’ve been around for a decade and customized the spectrum of their lights to maximize your harvest. In fact their mission statement says just that:
- Increase yield per square foot,
- Provide consistent high quality crop production capability,
- Decrease operating costs per pound of harvested product.
The evidence is on Viparspectra’s side and we think you’ll really love the 1200 watt full spectrum LED grow light they have to offer.
Viparspectra PAR1200’s Design:
The 1200 watt PAR1200 model is the cornerstone model of the Viparspectra brand. It’s got all the bells and whistles of a top shelf piece of equipment.
This light is designed with 240 LED chips and each chip outputs 5 watts of power. The LED chips used by Viparspectra are manufactured by industry standards EpiLED and Bridgelux.
It’s got a secondary lens meant to increase light penetration up to 200%.
The light features dual mode knobs for your plant’s veg and bloom phases. Each knob is adjustable between 25% and 100% power.
Viparspectra PAR1200’s Light Spectrum:
This light spectrum is everything your plants will ever need, as should be expected from a top of the line grow light. It includes wavelengths in the 440nm to 730nm range. The 730nm wavelength is infrared (IR) which helps during the flowering phase. Viparspectra spectrum is known to lean a little more toward the blue side, but in total it’s plenty to successfully carry your plants from seed to harvest.
This light is incredibly bright and should only be viewed with protective eyewear.
The dual mode switches for veg and flowering phase can be toggled to your liking, although we suggest 100% power regardless of which mode you’re using.
Dual mode isn’t completely necessary but many people like the convenience. The red light spectrum isn’t so helpful during the vegetation phase, but it doesn’t hurt if you leave it running.
Light Intensity/PPFD value:
The Photosynthetic Photon Flux Density (PPFD) value is the number you’ll see on the charts telling you how strong your light is at a certain point underneath.
This is a very strong light that’ll get your plants where you want them. It’s evidenced in the PPFD value of 958 at an incredible 28-inch hanging height.
Generally 460-925 PPFD is sufficient during all growth phases with 925 being the best. Beyond that you’ll get decreasing rate of returns on yield. Keep reading below for how to utilize this powerful Viparspectra PAR1200 LED grow light…
Viparspectra PAR1200’s Coverage Area:
Viparspectra claims the max coverage area is 4x4ft. But we’ll let you in on a trick to help you get the most out of this powerful light.
You can get a PPFD reading of 958 at 28 inches hanging height, but that’s only in the center. If you get out to 3ft at 28 inches high, it’s not as powerful or useful.
So we’d recommend hanging this light below 28 inches, closer to the norm of 18″ and here’s why:
If you hang this light perhaps 20-22″ height, you’ll lose coverage on the outer edge coverage area ~4ft from center, where it matters least. The intensity is already weak that far out.
But if you lower the light to a more normal hanging height, the PPFD value will increase intensity in the mid-range coverage area 2-3ft from the center where it matters more. You’d only be giving up an already minimal PPFD reading at the edges.
So you’ll lose some unnecessary PPFD on the edge where it’s already low, but gain a bit more in the mid-range coverage zone where it’ll be useful.
You just don’t see 1200 watt LED grow lights with this type of PPFD output so this is an incredible light.
This Viparspectra PAR1200 1200W draws 545 watts from your outlet at full power. With only veg mode it’s even less. Considering the strong PPFD values this light is putting out, the power draw is really impressive. Compared to a high pressure sodium (HPS) or metal halide (MH) grow light, the power consumption considerably less.
PAR1200 watt Cooling:
The Viparspectra PAR1200 comes with five high speed and silent front cooling fans. There are vents on all sides of the grow light. Inside is a large aluminum heat sink. Viparspectra wasn’t taking a chance on a heavy duty grow light like this.
It’s easy to feel cautious about heat when considering a large grow light whether it’s an LED grow light, HPS grow light or Metal Halide grow light. So we went to see what customers who already purchased this grow light are saying about the heat and fans.
One customer described the Viparspectra PAR1200 as stealthy quiet, making almost no heat. Another simply described it as silent. One person said the light didn’t raise their grow tent temperature more than a couple degrees after a prolonged period of use.
Fans were described as quiet, and performing very well by several reviewers. The general consensus from current PAR1200 owners for these features seems to be very good.
Viparspectra PAR1200 1200 Watt Compared to Other LED Grow Lights:
I wish there were an LED grow light comparable to the Viparspectra PAR1200 in terms of power consumption and wattage. But looking around, I truly don’t see one. It speaks to the uniqueness of this grow light.
Take a regular 1200w LED grow light from Phlizon or King Plus for example. They’re good brands but despite being 1200 watt, the PPFD values just don’t match up to the Viparspectra PAR1200. The coverage doesn’t match up either, and so they’re not really comparable despite all being 1200 watt grow lights.
Even the high end Advanced Platinum P1200 1200w doesn’t compare. You’d be paying more than 3x the price of the Viparspectra and use 50% more power.
This full spectrum LED grow light from Viparspectra really holds a unique place in the market. I’d venture to say it’s one of the best LED grow lights out considering it’s price and capabilities.
Warranty and Customer Service:
These are two important factors for consideration, and they become more important the more expensive your light gets. Luckily, Viparspectra offers a generous 3 year warranty on the PAR1200 grow light. There’s also a 30 day money back guarantee if you aren’t satisfied.
We’ve been reading what current owners of this light are saying. In general they’re all very happy as you’d expect with a top line grow light. A high percentage of reviewers gave this light a perfect score. More specifically they seem to appreciate the quiet fans, the cool running light, and of course the yield they get from their marijuana plants.
Of course there were the rare few instances where a customer mentioned an issue in the reviews. We were happy to see Viparspectra proactively reached out to them and made offered to help them out.

Other Common Questions About The Viparspectra PAR1200 LED Grow Light:
How much does the Viparspectra PAR1200 weigh?
- It weighs 27.5lbs -- Most grow tents support 60-120lbs.
What size grow tent is the Viparspectra PAR1200 good for?
- Viparspectra says this light covers 4ft x 4ft (veg) and 3.5ft x 3.5ft (flower), but the areas farthest from center can be a bit weak, so we recommend 3x3ft at 20-22″ height.
- Some current owners say it’s enough for a 4x4.
What voltage is supported?
Do you need to use additional ventilation or fans?
- No, the fan cools itself well. Most users report couple degree increase at most.
How low does the grow light hang from mounting point?
- Supplied hangers will hang it 8-inches from the hanging point, unless you customize it for more/less with your own tools.
