With 10 years of development expertise, they are recognized as producing quality and durable LED grow lights. For starters, their products are UL safety certified.

Viparspectra 900W Product Information

Sleek-looking, the Viparspectra 900W is designed for indoor growing activities and offers full-spectrum light, including visible light, ultraviolet (UV), and infrared (IR) light. It’s also energy efficient by using only 418W to provide the intensity equal to 1000WHPS. This helps reduce your operating cost per pound of the final product. 

A great feature of the Reflector Series is the built-in reflectors that help direct all the light towards your plant without scattering the light around in the tent or room. This reflector design also increases the PAR output by 50 percent. It uses blue light when the VEG switch is on and red light when the BLOOM switch is on. There are separate switches for each mode. Most customer reviews indicate it works best for vegetative stages but is still adequate for flowering. 

You also don’t have to worry about it overheating since there is an aluminum heat sink and two high-speed fans. Typically, it runs 70 percent cooler than HID lights. If your grow tent is properly ventilated, the light will increase the temperature to around 5 degrees Fahrenheit. However, this can be up to 10 or 15 degrees depending on your ventilation.

Coverage and PAR Value

For 4×4 feet of coverage, the recommended hanging height is 32 inches for vegetative stages. For the flowering stages, it is recommended you hang the light at 24 inches for 3×3 feet coverage. Generally, lower hanging heights produce higher PAR values. This LED grow light also isn’t designed to concentrate light into the middle of the plant canopy, so you don’t have to worry about burning or stunted growth. 

You can control your PAR value by moving the light closer or further, using the dual-mode switches, or the automatic timer. The PAR output values vary at the following hanging heights:

• 6 inches: 2125 umols
• 12 inches: 1416 umols
• 18 inches: 915 umols
• 24 inches: 608 umols
• 36 inches: 298 umols

Warranty Information

The Viparspectra 900W grow light provides a 3-year warranty that is longer than most competitors in the market. Some customer reviews indicate the unit stopped working after 2 years. However, this is still within the warrantied timeframe. 

They also provide a 30-days money-back guarantee for all their LED grow lights. If you have any questions or seek professional guidance on helping your plants grow better, Viparspectra encourages you to reach out and contact them.

Recommended Add Ons

It is recommended to purchase protection glasses when entering the grow room or tent since this grow light produces high light intensity and PAR output. Using them will allow you to get into contact with direct light safely. Since some reviews say it’s a better product for vegetative stages than flowering stages, customers have found having a bloom booster for their plants helps make up the difference.
