ThinkGrow ICL-120 Lights the Bottom of the Plant
Overhead fixtures do most of the work, but the lowest branches rarely see enough light to finish well. Those sites tend to produce small, airy flowers that end up as trim. The ICL-120 sits below the canopy and aims its output upward in a 120-degree spread. Each bar draws 120 watts and puts out 348 µmol/s from a single full spectrum channel. That works out to 2.9 µmol/J at the fixture. The driver is built in and autosenses 100–277V, so one part number covers both common commercial voltages. Each bar measures about 43.7 in long, 3.72 in wide and 2.74 in tall. The housing is sealed, and distributors list it at IP66 for washdown-heavy rooms. ThinkGrow rates the diodes at L90 for more than 54,000 hours and backs the bar with a 5-year warranty. This listing is two bars, a practical size for one bench or a test row before a full rollout.
Setting Up an Under Canopy LED Bar Row
Mount each bar on a pair of stands so it sits flat beneath the plants. The TSD-3 vertical stand is built for this bar and is sold separately. Bars link end to end through male and female ports that lock together. Place the input of one bar right next to the output of the next before locking them. Power cords are not included, so plan the feed for the first bar in each run. Keep the bars low enough to clear the lowest branches without contact. Plan the row layout before the plants get too dense to work underneath. The operating range runs from -4 to 104°F, which suits both flower rooms and cool greenhouses. Wipe down the lens during turnover, since leaf debris and spray residue cut output over time. For larger rooms, the 4-pack ships the same bar in a single carton.
