Viparspectra 300W Led Grow Light Review

Indoor growing is a trend that is gaining a lot of traction in many parts of the world. People who practice gardening as a hobby can now do it from inside their houses and still expect a bountiful harvest. If you are just hearing about this, you might be wondering how it is possible, considering that there is no sunlight that the plants so desperately require.

Well, this problem is simply solved by introducing an LED grow light to the plants, which provides them with all the light wavelengths they normally get from the sun. In a nutshell, the LED grow light acts like a modified indoor sun.

If you are thinking of joining the world of indoor cultivation, you may be asking yourself what is the best LED grow light to kickstart your new interest.

With dimensions of 12.6 by 7.9 by 3 inches, the Viparspectra LED B01B4GQ6MO light is fairly small and will provide light to cover a 2 by 2 feet growing area. During the flowering stage, when the light is closer at around 15-20 inches, it will cover 1.5 by 1.5 feet of the growing area.

This may not be a huge area but it is enough to get you started on the indoor growing idea. However, if you want greater coverage, you may as well opt for two or more of these lights. Fortunately, this light is very affordable so it shouldn’t be too expensive to add extra units.

Watt Coverage and PPFD

One of the key components to consider when shopping for an LED grow light is the PPFD value. The Viparspectra 300 Watt produces 412umol at the center, and around 120umol by the time you get to 2 feet away. This is not the highest PPFD you can get from an LED grow light, that’s why I suggest using it on one plant or combining it with other light units to broaden the coverage.

You can further use it as a booster light, whereby it fills out some weak spots when you add it to other lights. If you are in any of the above situations, the Vipaspectra 300W will be a good choice for you.

For people who have purchased this light to grow their marijuana plants, most agree that the Vipaspectra does a good job. Generally, the reviews you find online are more than encouraging.

Power Efficiency

Power efficiency is another key aspect that you should consider when buying an LED grow light. Fortunately, a low watt light like this one shouldn’t give you sleepless nights about the power it consumes, unless you have installed multiple units.

When it comes to the power draw, this LED only pulls 130 watts from your outlet, which is very manageable. According to one customer, this is equivalent to $10 a month ($0.13 per kW/h). And the figure is from operating the Vipaspectra LED light almost 18hrs a day.

This is just a fraction of what you’ll spend on other LEDs in the 300W segment, as far as power consumption is concerned. When you add this to the relatively low initial investment cost of the light, you are left with a very impressive product for a first-time buy.

Heat Output and Cooling

One of the main concerns in indoor cultivation is the cooling capabilities of the grow light you are using. But with a low-power LED light like the Vipaspectra 300 Watt, you shouldn’t worry much about the level of heat it generates.

Aside from the low heat generation, the light features a 4.72” cooling fan, to go with an aluminum heat sink to assist in the cooling aspect. This is far better than other grow lights selling in the market it this segment.

One user said that the heat from the light is low and quite manageable, whereas a fellow user revealed the light barely emits heat and the fan runs quietly. You won’t even have to use an inline fan when using this LED.


Customer Service and Warranty

The customer service at Viparspectra is responsive and will answer any questions you may have to improve the experience of using their product. Anytime you buy this LED grow light, you get a hassle-free 3-year warranty, which is a long time for a light this affordable.

Additionally, you still get a 30-day money-back guarantee in case the light fails to live up to your expectations functionally. With an average shelf life of about 100,000hrs, you’ll more than likely be getting your money’s worth.
