Viparspectra 1200w- Yield and Using Instruction

(Last Updated On: August 19, 2022)

If you are newbie in the world of indoor gardening, or even maybe you’re already a seasoned expert, but haven’t yet found the right LED panels, then the Viparspectra 1200w is the perfect choice for a 4.5’x4.5’ vegetative coverage at 32”and 3.5’x3.5’ flowering coverage at 24”.

The LED lighting panel is meant to offer the most appropriate balance between lighting coverage for a specific grow tent size and the right PAR per Lumen output. The PAR is the Photosynthetic Active Radiation, which is the lighting responsible for plant’s growth through photosynthesis.

In simpler terms, the Viparspectra 1200w offers full spectrum of lighting colors (blue, white, red), which is optimal enough for the vegetative and flowering stages. Technology behind the Viparspectra products are known to offer lighting that mimic the sun’s natural capability.

The final results of its full spectrum lighting and balanced PAR coverage is fast growth rates and high yields, which make It is one of the best led grow light for 4×4 grow tent.

What if your tent is of other sizes? Don’t worry because Viparspectra comes in other sizes – 450w, 600w, and 900w, which have the same high yield effects, but meant for other grow tent sizes.

Viparspectra 1200w Grow Light – Everything You Need To Know

Energy Efficient

The Viparspectra 1200w designed with 240 pieces of LEDs emitting 5w of lighting intensity. Which isn’t that much compared to other LED products. However, when compared to the likes of Mars Hydro TSW 2000w, its 545 watts energy consumption is a little bit high. The Mars Hydro consumes about 300w.

Still, the Viparspectra has a lighting efficiency incomparable to none of its rival grow light LED brands. For instance, the manufacturers of the Viparspectra 12000w brand have gone an extra mile to do tests for various grow tent sizes.

The 1200w series is perfect for a lighting coverage of a 48x48x80 grow tent at a distance of 40 inches above the plants’ canopies. This is particularly best for the vegetative stage. For flowering stage, the Viparspectra 1200w led grow light is also great for 3×3 grow tent, at a 36 inches distance from the plants’ canopies.

Dimmable Capabilities

Although the Viparspectra 1200w doesn’t have the dimmer, its sister – the Viparspectra PAR 1200w Dimmable Series – comes installed with the dimmer.

The LED panel has been designed meet different spectrum demands, meant for different growth stages. Because of this, the PAR 1200w utilizes separate VEG and Flowering dimmer controls. It alternates the lighting colors between red, white, and red lighting spectrums.

This is the feature responsible for guaranteeing the right balance between PAR per Lumen and lighting coverage. It’s important to notice that the Viparspectra 1200w has been designed with infrared LEDs that promotes cell division. This helps with the plants’ leaf building, germination, and flowering.

Offers Full Lighting Spectrum

As aforementioned, the Viparspectra 1200w provides the plants with optimal lighting spectrum that’s best for important growth stages – flowering and vegetative. This optimal spectrum mimics the sun’s natural lighting, which is perfect for the plants since they get all the needs and desires required for fast growth.

It secondary optical lenses have also been engineered to magnify PAR and thus increase canopy penetration by 200 percent.

Moreover, the Viparspectra advances a PPFD of up to 1020 umol/m2/s at 24 inches above the plants. This enables the plants to have a fast scalability from the seeding stage to blooming.

The best thing about the Viparspectra series is its advancement from previous version to newer, better versions.

That is, the manufacturers are always trying to better themselves from the previous series release. For instance, while the initial Viparspectra 1200w led grow light focused mainly on purple color, and the red and the blue colors as well, the latest versions are focused on warm white colors.

Nonetheless, the brand doesn’t do away with the red and blue colors. Instead, it balances all the grow light colors to guarantee a full spectrum.

Sturdy Design & UL Certified

The panel’s design is sturdy and looks like it can actually last many years, especially with its 100,000 hours of lifespan. The Viparspectra PAR 1200w led grow light has undergone many years of cautious testing and experimentations.

The manufacturing designers weren’t just about efficiency, but also took safety and sturdiness very seriously – which is noticeable with its robust-like build.

Once you hang the LED panel, its feels comfortably placed, and seems like it’s never gonna fall off. Some user complaints about its weight shouldn’t be a put off, because it never falls off from the grow tent. It stays put, and safe.

For safety, the Viparspecra 1200w comes as a UL Certified product, meaning that it had to go rigorous UL testing for safety standard. This makes sure its operations within a grow tent are danger-free.  

Basically, the Viparspectra brand is reputable and respected among enthusiast home growers.

Non Heat Dissipating Fan

As indoors growers, the last thing you need are complaints from neighbors due to noisy sounds and humming coming from your house. You need a quiet, stealthy operation. Which is exactly what the ViparSpectra 1200w delivers.

The LED panel comes installed with front fans, which have been designed to discharge minimal heat emissions. This helps keep the hydroponic grow tent at an optimum temperature required for the plants’ growth.

Also, this saves you lots of money on electric bills. It’s a viable option if you are just a simple, non-commercial indoors gardener, where you have to worry about electric bills.

Anyways, the front-fans have been made in such a way that they blow heat away from the plants. The vents are at the panel’s top region, which makes sure none of the heat gets blown downwards.

Moreover, the fans are made of an aluminum heat sink, which further cools down the ViparSpectra 1200w LED panel.

Amazing Customer Care

This shouldn’t even be listed as Viparspectra’s notable features, but it’s worth mentioning anyways.
