VIPARSPECTRA Reflector-Series 300W LED: Features & Specifications

I already told you VIPARSPECTRA V300 has designed for beginners but this is not cheap in quality.

12-Band Full Spectrum Affordable Light

I call this light Affordable, which comes at an attractive price to support your indoor plants with efficient and bright light.

12-band full spectrum of LEDs, including Infrared makes VIPARSPECTRA Reflector Series V300  ideal for many types of plants.VIPARSPECTRA Reflector-Series V300

When a seed is germinating it seeks red and far-red (Infrared) light waves. As those infrared light spectrums are far away, the plant will try to reach it so outdoor cannabis plants can grow to be 7′ or taller.

Generally, Indoor growers have limited vertical space for plants. It is really impressive that because of VIPARSPECTRA Reflector-Series 300W LED Grow Light your cannabis plants won’t need to stretch as much to get the Infrared light spectrums.

Quality of LEDs & Focusing Angle

These grow lights equipped with superior quality 60pcs 5W Bridgelux/Epileds LEDs. Generally LED Focusing angle ignored by buyers but it’s important for the cultivator to achieve better canopy penetration & plants health. This Plant Grow Light comes with 90° LED Focusing angle.

Light Efficiency: PAR Output

Balanced PAR output is very important for every plant and the measurement of PAR tell you how much edible lights are getting your plants. For seedling, necessary PAR output is 200-400 µmol m-2 s-1 on average & as your plant grows the requirement of PAR increases. In the flowering stage, your plants need more than 400 µmol m-2 s-1.


At 24” height, the PAR output of VIPARSPECTRA Reflector-Series 300W is 237 µmol m-2 s-1 at the center, which is perfect for seedling. You can fix your light at this height primarily and move it nearer for higher PRA as your plants demand. When your plants come to the flowering stage you need to set it at 18″ height while the PAR output will be 412 μmol m-2 s-1.

HPS Replacement With VIPARSPECTRA Reflector-Series 300W LED

Fluorescent and HID/HPS grow lights generally consume more power than LEDs. This can replace traditional 250W HPS or MH grow light while consuming only 128 watts while working! Moreover, these LED lights don’t require a ballast.

VIPARSPECTRA Reflector Series V300 Cooling Ability

Management of heat within the grow space is the biggest challenge for indoor gardened. This lighting system equipped upgraded aluminum cooling heat sinks and high-speed quiet fans for heat dissipation inside grow tent. So these lights run almost 70% cooler than comparable HIDs.

Warranty Period & Lifespan

VIPARSPECTRA comes with 30-days satisfaction or return guarantee and 3-years local warranty with excellent customer service.

Lifespan of these plant grow lights is 100,000 hours. If you turn on this light 18 hours every day it will last for 15 years! So most probably you will upgrade this before needing a new one.

Coverage & VIPARSPECTRA 300W Distance From Plant

This light is relatively small so it’s perfect for the first growing experience. VIPARSPECTRA V300 recommended for 2x2ft vegetative coverage at 24″ height & 1.5×1.5ft flowering coverage at 18” height. But don’t worry much because so you’re free to extend your grow space any time by adding one more light as these LED lights featured with daisy chaining ability. You have to adjust VIPARSPECTRA 300W distance from plant according to growth stage.

Viparspectra V300HeightPAR OutputCoverage
Vegetative Stage24"2372x2ft
Flowering Stage18"4121.5x1.5ft
Extreme Flower Stage16"5021.5x1.5ft

A mature cannabis plant commonly takes around 1 square foot to grow. So you can grow 4 marijuana plants with this light generally. But think about 3 square foot flowering coverage! so I advise for 3 plants unless you’re going to add supplemental light for the flowering stage.

Frankly speaking, this grow light is the best choice for Vegging & less ideal for bloom. But please don’t think it’s possible to grow a full plant using this light, I am just talking about the best pick.

These small LED Grow Lights are not waterproof so this light recommended for indoor use only.
