Frequently Asked Questions

Why ALT?

We deliver more power at greater efficiencies. Our spectrum allows plants to reach their optimal growth potential, while other LED’s have historically been sub-par during flowering stage of growth. We have created a revolutionary technology that is the most effective and efficient LED grow light on the market.

Why use LED over HID?

LED’s have longer lifespans and produce much less heat than HID grow lights. In our tests, our LED’s provided equal or greater products than HID’s in quality, quantity and potency. They produce more yield per watt and therefore can reduce energy costs by up to 75%. Results can vary based on growers experience and environmental surroundings.

How many watts are used in each of the lights in the Radiant Series?

Our Radiant 500 light uses a total of 120w. The Radiant 2000 light (the Quad) uses a total of 480w. Our RS-28 strip light uses 28w.

Which light would work best for my needs?

The Radiant 500 can be used both for indoor commercial farming as well as domestic growing. The Radiant 2000 was designed for use in commercial grow houses but can also be used for larger scaled home growing. The RS-28 is best used for long, rectangular plant beds. It is used for lettuce, herbs, and leafy vegetables.

How do the Radiant Series lights interact with a variety of plant species?

The unique spectrum of the Radiant series has been proven in tests to work well with all plants since it has the optimal spectrum in which plants need to flourish. The RS-30 is specifically is designed for leafy vegetables and herbs while the Radiant 500 and Radiant 2000 can be used for many different plant applications. Note that results may vary due to experience and environment.

How much money can I save by using LED lights instead of HID?

Our LED’s can save as much as 75% on energy costs. Please refer to our performance page for more specific information.
