Best Samsung LM301H LED Grow Light For Indoor Plants 2021 Update
Samsung announced the LM301H mid-power LED that the company says delivers the “highest photon efficacy” in the industry for a mid-power, phosphor-converted white LED. The performance claim refers to the horticultural-centric metric micromoles per joule (µmol/J) that describes the efficiency of a solid-state lighting (SSL) device in converting electrical energy to photons in the so-called PAR (photosynthetically active radiation) spectrum between 400–700 nm.Simplified, photon efficacy is a parallel metric to lumens per watt (lm/W) that’s used to characterize lighting efficacy for humans whereas the plant metric characterizes photosynthetic photon flux (PPF) relative to power.
Samsung said the LM301H packaged LED delivers 3.1 µmol/J and that luminaires could use 30% fewer LEDs to deliver the same PPF compared to luminaires based on other mid-power horticultural LEDs. “This breakthrough in photon efficacy will go a long way in helping indoor farm owners to maximize plant growth and quality, as well as their profits,” said Un Soo Kim, senior vice president of the LED Business Team at Samsung Electronics. “We are committed to continue innovating white LED solutions optimized for healthier plant production as we solidify our leadership in the horticulture lighting industry.”Samsung showed a new version of the mid-power product called the LM301H One that boosts energy in the red spectral region.The LM301H One is an attempt to deliver the red-energy benefits without mixing two channels of LEDs. As the nearby image shows, the mixed design uses far more white LEDs than red ones, but still such a design will require multiple driver channels. And uniformity of light will always be an issue. The LM301H One uses a phosphor composition that’s richer in the red region, presumably adding some cost at the component level but enabling a more cost-effective luminaire design and better uniformity of light.
HLG 650R Quantum Board LED Grow Light:
The HLG 650R is a 630 watt LED grow light designed for full cycle cannabis growth. This grow light uses the newest Samsung LM301H LEDs, and emits stronger light intensity than the HLG 600 models.
Features:
Wattage:630 Watts (Dims to 60w)
Spectrum:4000K + 660nm Red
Energy Efficiency:2.85 umol/Joule
Coverage:7x7 ft (veg) / 5x5 ft (flower)
Voltage:90–277 VAC
Amperage:5.08 at 120v; 2.54 at 240v
LEDs:Samsung LM301H
Dimensions:29 x 22 x 4 inches
Hang Height:Flowering: 30 inches / Veg: 48 inches
Warranty:3 Years
Spectrum:
The new Samsung LM301H LEDs light your plants with 4000K spectrum. This spectrum is good for full cycle cannabis growth. The impressive part about the HLG 650R spectrum is that HLG was able to max out both blue and red wavelengths, making it ideal for full cycle plant growth.
As you’ll see below, the 4000K spectrum offered on the smaller HLG 550 Eco has considerably less red light in the mix, so the 650R is an improvement on that front.
HLG 650R Spectrum 4000K — Good for all phases of growth:
Coverage Area:
The HLG 650R covers 5x5 feet during flowering, or 7x7 feet during the vegetative phase of growth.
If you’re using a 5x5, 5x10 or any tent size divisible by 5 feet, you’ll likely want this model over the smaller HLG 550 V2. If you’re growing in a 4x4, 4x8, or any tent size divisible by 4 feet, you’ll likely want to go with the HLG 550 V2 and save a few bucks.
