Samsung Diodes Are Ending, and Here’s Your Last Chance

Samsung’s horticultural LED diodes that helped define a golden era of efficiency and reliability are nearing the end of their run. Rumors have been spreading for a while that Samsung is shutting down its diode line. That means this is likely your last chance to pick up our FC LED grow light series, famed for Samsung-powered performance, at clearance pricing while stock lasts. First-come, first-served.

Why Growers Fell in Love with Samsung, and the FC Series

Samsung’s LM301 family built the backbone of many classic fixtures, including Samsung-equipped batches of the Mars Hydro FC Series, because the diodes deliver elite numbers at sensible drive currents.

Snapshot from Samsung’s own specs (at 65 mA, 25 °C):

• LM301B: 0.2 W, 3 V mid-power LED; 38.8 lm @ 65 mA; 220 lm/W luminous efficacy.
• LM301B EVO: 0.2 W, 3 V mid-power LED; 40.2 lm @ 65 mA (5000 K); 230 lm/W luminous efficacy.
• LM301H EVO (horticulture): 0.56 µmol/s photon flux; 3.14 µmol/J photosynthetic photon efficacy (PPE); anti-sulfurization package.

Unmatched Efficacy & Rock-solid Stability

With diode-level efficacy up to 230 lm/W (LM301B EVO) and 3.14 µmol/J PPE (LM301H EVO), Samsung set the benchmark for efficient, repeatable output growers could count on run after run.

High PPF Per Watt

The LM301H EVO’s 3.14 µmol/J class diode gives fixtures a high ceiling for photon efficiency. The FC Series leverages dense arrays and quality drivers to turn those diode numbers into strong canopy PPFD and productive watts.

Excellent Spectral Balance

Variants like 5000 K on LM301B EVO make it straightforward to compose balanced, full-spectrum arrays that drive confident veg and bloom performance without starving key wavelengths.

Lower Heat, Higher Comfort

These are 0.2 W, 3 V mid-power packages, meaning lower heat density per emitter. Paired with the FC’s large passive heatsinks, temps stay manageable, and HVAC load is lighter than legacy, high-temp fixtures. The LM301H EVO’s anti-sulfurization construction further protects performance in humid grow rooms.

The Mars Hydro FC Series, built around Samsung diodes, earned its reputation for commercial-grade uniformity, top-tier efficiency, and dependable yields, all at an accessible price point. Once the Samsung-equipped FC units are gone, they’re gone. If you want the Samsung feel and familiar results, now’s the time.
