Dialed In Tri-Spec 150W 3-Channel Under Canopy LED Grow Light

Most under-canopy fixtures push a single fixed spectrum. The Tri-Spec gives you three independently tunable channels — Full+Red, Far-Red, and UV — so you can adjust the light itself by growth phase or cultivar instead of running one spectrum for the whole cycle.

The 730nm Far-Red channel triggers the Emerson effect, which improves how efficiently plants use light at lower canopy sites. It helps light penetrate deeper into the canopy, supporting faster, fuller finishes on bud sites that overhead lighting typically misses.

UV is optional to run but adds real value — it boosts trichome density, coloration, and terpene production, which directly affects bag appeal and aroma. Since each channel dims independently, you can dial UV up during late flower and reduce it earlier in the cycle.

Yes. The fixture carries an IP66 rating, meaning it's sealed against dust and protected against water jets, and it uses passive fanless cooling with no vents for moisture to enter. This makes it well-suited to humid grow rooms and washdown-cleaned facilities.

The Tri-Spec supports daisy-chaining up to 8 units per circuit, letting you scale coverage across a tent or room without running a separate power drop to each fixture.

Dialed In recommends mounting the Tri-Spec 8"–20" (20.3–50.8 cm) under the canopy. Exact placement depends on plant density and how deep you want the light to reach into the lower bud sites.

The Tri-Spec runs on universal voltage (120–277V) and draws up to 1.25A at 150W input, making it compatible with most standard grow room electrical setups when using the Dialed In 150W UC Power Cord.
