Ultimate Guide and Review For The Viparspectra 300w LED Grow Light

viparspectra 300w reviewReviewing the Viparspectra 300w Grow Light was a no brainer. Based on this LED grow lights popularity around novice growers, we wanted to put forth our Viparpectra 300w review to better understand why this light is held in high regard with its growers.


Why is the Viparspectra 300w so popular?

For starters, Viparspectra is still a fairly new company but has already started off with a great reputation for creating LED’s that make the mark for indoor growers. Every LED grow light they make, from the Viparspectra 450w to the PAR600 is built with indoor growing in mind.

Viparspectra 300w Par

For instance, the PAR rating for the Vipar 300w LED grow light produces a steady even PAR that allows for 100,000 hours of high quality PAR light for your indoor garden. Because the Viparspectra 300w balances the PAR so well for each stage of growth it has the ability to give your plants the light spectrum they need. Using Epiled LEDs and BridgeLux LED, both quality light chips, this 300w LED did not let us down or disappoint.

Also, the typical 5 watts LED bulbs nestled into each and every Viparspectra has been quality tested and set up to take full advantage of its full spectrum array of light. LED’s, in fact, have so many benefits for indoor growers that at this point in time, settling for a different type of bulb is almost foolish. This is going to be a fun Viparspectra 300w review so read on for the best insights into why this light is perfect for growing.

Benefits of LED Bulbs

Bulbs are probably the single most important thing to consider when growing. With LED bulb the advantage is obvious.

  • Energy usage is drastically cut in half compared to HPS bulbs or similar
  • Heat reduction. Plants hate to much heat when growing
  • Life expectancy is around 50,000 hours
  • Far less costly. Especially with the Viparspectra 300w LED grow light
  • Full spectrum LED light allows the use of both veg and bloom lighting cycles

So, you can see why LED’s have pretty much taken over the grow light market. The Viparspectra 300w LED is no exception.

Viparspectra 300w Review

To start, the panel of this Viparspectra is easy to use and operate. Perfect for beginners who typically start with a small grow of maybe 1 or 2 plants. It has a fairly small coverage area at around 2 feet by 2 feet. It does, however, reach deep through the plant’s canopy and does it well.

Check Price

The embedded 5-watt bulbs supply a good mixture of full light spectrum LED light along with IR (Infra Red) and UV (Ultra Violet) lighting.

Our light arrived on time and in discreet packaging. The package itself came with the Viparspectra 300w LED grow light, one hanging kit, power cord and user manual. The V300 Viparspectra is part of Vipar’s reflector series lighting line up.

Along with these LED grow lights durability came a 3-year warranty so if something goes wrong it is easily replaceable. We still have not had this brand break down on us, but it is nice to know the warranty is there.

Daisy Chain LED Grow Lights

Although the Viparspectra 300 watt V300 is small, it can be expanded as your grow room expands. We used one Viparspectra 300w during our review, however, if we wanted to use a 2nd or 3rd light to increase our yields we could have easily done so with a certain feature.

The feature is called a “daisy chain”. This allows you to connect a series of LED grow lights together to increase your growing yields by producing more plants. They simply plugin, one after the other to multiply your light output and increase your coverage area. A very nice feature.

This means that if you start to get the knack of indoor growing, you can easily expand and grow more.

LED chips by top manufacturers

Viparspectra is known for their chipsets. Made by reputable LED lighting manufacturers, these 5-watt bulbs come from companies such as Bridgelux and Epiled. Two well-known liquid emitting diode manufacturers. The LED’s in Viparspectra’s reflector series LED lights are angled at 90 degrees so they point straight down at your plants.

The 5-watt LED bulbs that VIPARSPECTRA uses come from well-known companies like Bridgelux and Epiled, manufacturers that both have good reputations. VIPARSPECTRA has the LEDs mounted at a 90-degree angle pointing straight down at your plants.

Viparspectra 300 watt light output specifications

PAR and lumen are the measurements of light output for a particular LED grow light and lighting in general. Many people get caught up in this measure but keep in mind there are many factors that ultimately control the yield of your crop and adverse effects on your plants.

This was especially important with our Viparspectra 300w review as this model does not seem bright to the naked eye, but without eye protection, you can seriously damage your retinas. We always recommend using protection such as the Apollo Horticulture UV400 eyeglasses. They fit nicely over prescription glasses and do a great job of protecting your eyes from damage while growing weed.

The more PAR and Lumens, the stronger the intensity of your LED grow light. V300’s PAR is best when the light is hung 2 feet over the top of the plant’s canopy.

With this in mind, the ease at which the light is able to be raised is efficient with the included hanging kit. I tend to ignore lumens as this is a measure of grow light intensity to the human eye which is dangerous if you are trying to measure this yourself. Never stare directly at LED’s even if they seem dim. Always use protective wear such as the Apollo Indoor Growing Glasses.

PAR is more of the lighting measure we are after. It combines light coverage along with intensity. Based on the Viparspectra 300 watt grow light PAR plants in their vegetative cycle should have the lighting coverage at 2 feet by 2 feet and the same goes for the flowering stage for best growth results.

Keep in mind, don’t crowd your plants. If you need more plants, you will need more lights. If this is the case, these lights have a daisy chain feature that can accommodate this.

How many plants can you grow with the Viparspectra 300W?

One cannabis plant generally means one square foot, which means with the Viparspectra 300w reflector series LED grow light you can conceivably grow 2 plants at a time. Total best coverage area is 2×2 although you can expand out to a 3 x 3 growing area, which we do not recommend.

If you need that 3rd plant you should buy 2 of these LED lights. For our Viparspectra 300w review, we used a single unit for our LED grow for a couple of reasons. The Viparspectra 300w is a low-profile built grow light that can fit into small grow tents. Because of this, we wanted to use it in a real-world setting to ensure our review was close to what one might do if they purchase this LED grow light.

Additional VIPARSPECTRA 300-watt LED grow light specifications:

  • Weighs in at 5.6 LBS and is 12.6 inches long and 7.9 inches wide by 3 inches tall
  • Hanging kit included
  • 6-foot power cable
  • 50-60Hz, 100-240V AC
  • 60 5-watt LED lights in total
  • 30 days satisfaction or with a return guarantee.
  • Whisper quiet fans for noise reduction and cooling built-in
  • Comparable to a traditional 250 watt HPS/MH  consuming only 136 watts of electricity
  • Avg. Power Draw: 136W±3%
  • No additional ballast needed

To use a ViparSpectra grow light, you will need to first identify the plants you want to grow. You will then need to find the light that is best suited for those plants. Once you have identified the light, you will need to find a space in your home or garden that can accommodate the grow light. Finally, you will need to set up the light according to the instructions provided.

3. Is Spider farmer better than Mars Hydro?

Mars Hydro lights have an efficiency rating of 2.2 micromoles per joule, which is still a bit lower than the Spider Farm lights. Additionally, they are fanless and produce very little heat.  

4. How do you use a grow light with a veg and bloom switch?

To use a grow light with a veg and bloom switch, you first need to identify the type of LED grow light you are using.

If you are using an HID grow light, you will need to use a ballast with a veg and bloom switch. The veg and bloom switch will allow you to control the amount of grow light your plants receive.

5. What color LED is best for flowering?

Blue and red LEDs are most commonly used for flowering plants. Blue light helps to promote vegetative growth, while red light promotes flowering and bud production.
