From Veg to Flower

SpecGrade’s powerful yet versatile Verta is perfect for both flowering and vegging (with a 0-10V dimmer) in indoor applications. Its modular design allows you to change out the circuit boards should you choose to switch the spectrum or increase the efficacy as technology evolves. The proprietary thermal management system radiates less heat onto the plants while at the same time delivering unprecedented light levels and uniformity. The finely-tuned A-1 ‘Entire Life Cycle Spectrum’ has proven at universities and various grow environments to improve the trichomes and taste while cutting operational costs and shortening grow cycles.

The standard 10-year warranty on the LED boards and 7-year warranty on the drivers coupled with the new UL8800 certification says volumes about how Verta’s robust engineering will stand up to harsh grow environments. Use it to increase current ROIs & yields.

Heating Element

Sometimes Less Is More...

Less Heat

Our proprietary engineered printed circuit boards together with our extruded aluminum heat sinking are designed to conduct heat away from the plants. This enables you to suspend the Verta within 6” over the plant without fear of giving it too much heat.


Less Height

We’ve designed the industry’s most low-profile grow lights. The Verta’s height, at only 3.3”, is designed to enable you to optimize the vertical growing space.

Construction: Modular and Robust

As technology improves, or you wish to try a different spectrum, the Verta’s modular construction allows you to swap out the circuit board in order to change the spectrum or improve efficacy.

Because grow lighting equipment is commonly exposed to water, dust, dirt, humidity, and high levels of ambient temperatures, on May 4, 2017 Underwriters Laboratory (UL) published UL8800, a set of safety requirements to be used when evaluating lighting equipment. That includes not only the grow light, but also non-permanent cords and plugs for indoor farming applications. The specifier should look for this UL safety mark before purchasing this type of equipment. 



No other grow light is able to deliver as excellent of a uniformity ratio as the Linea ensuring an equal blanket of photons across the canopy.


Antimicrobial Finish (Optional)

Our antimicrobial paint additive, optional with select SpecGrade grow lights, is formulated to provide lasting and effective protection against harmful microorganisms such as bacteria, viruses, fungi, algae, mold, and mildew.

10-7 Warranty Badge Graphic

10/7 Warranty

Because we build each grow light to the highest standards, we feel comfortable providing the 10/7 Warranty. Every SpecGrade grow light comes with a 10- year warranty on the LED boards and a 7-year warranty on the drivers. View our warranty details here.


DLC Certification

The Verta qualifies for the Design Lights Consortium (DLC) certification, an independent third-party authorization that most utilities will commonly look to before considering any rebates to owners of indoor farming facilities. However, before putting a manufacturer on their Qualified Products List (QPL) they are required to meet a number of performance criteria.


Daisy-Chain Wiring Solution

SpecGrade offers our clients a Daisy-Chain Solution that significantly reduces the
cost of an electrical contractor dropping a wire for each grow light. Or, it can turn
the project into a time-saving do-it-yourself job.
