The Infinity Linear LED grow light from Thrive Agritech is a unique horticulture lamp that brings a lot to the table. In this test, I compare these LEDs to 4ft T5HO fluorescents. Supposedly a single Infinity Linear can replace TWO 4ft high output T5s. So I’ll run four T5s against two Infinity Linears (placed side-by-side).

Here are some newer LEDs that offer an excellent value:

I grew a single row of Kratky’s hydroponic lettuce plants (four under the center of each light). I selected Red Sails, a fast growing leaf lettuce. The lights were placed 9″ above the seedling canopy (10.5″ above the soil surface). Lights were not raised during the test. The Infinity Linears were placed alongside each other on 6.75″ centers.

LED vs T5 Test Results:
3:16 – Test Bed Placement
3:25 – Nutrient Setup
4:34 – Recorded Data
4:46 – Growth Comparison
5:16 – Growth vs Water Consumption
5:46 – Yield vs Water vs Power
6:14 – Power Cost vs Plant Yield


In my test, I was able to achieve 36% MORE growth, using 36% LESS power. The LEDs generated much less heat. This resulted in 36% LESS water consumption. When comparing the energy costs to run each light, and the resultant growth, the LED grow lights produced twice as much lettuce mass per dollar of electricity. So these lights really do live up to their claims.

The Infinity Linears are lightweight, water proof, and versatile in their configuration options. They’re ultra-efficient. My version produces 2.0 micro moles of light per joule. But the latest models have been upgraded to an efficacy of 2.2! Many LEDs claim to have a long lifespan, but in a year’s time I’ve seen them flicker or burn out. Thrive Agritech stands behind their products though. Their five year warranty is a big deal.

Unlike some COB and UFO style LEDs, the Infinity Linears do not generate a single hot spot of point light. Instead, they emit light in a continuous linear nature. I think these lights are good for close placement, fixed location installations. Perfect for a grow rack. They could certainly be raised, but in a long daisy chain configuration, doing so might be impractical.

Look for these to excel at vege cycle plant growth and propagation systems. Plant cloning, seed starting, culinary herbs, lettuce greens and microgreens. These are good for home gardening but commercial operations as well: Greenhouses, Vertical Farms, Tissue Culture Labs, Hydroponics, Aeroponics and Aquaponics.

NOTE: Thanks to Thrive Agritech for sending me these lights to keep. Although this review was unpaid, I did not have to pay for the lights.
