LUMATEK ZEUS 600W LED Luz de Cultivo VS ECO Farm 240W/640W Samsung LM561C+OSRAM 660NM+ LED Barras de Luz Regulable ... VS ECO Farm LM301B/LM301H Quantum Barra. 1 ... LM561C F-series Strip -> 8670lm LM301B Strip -> 3680lm This is a difference. You have to pay more than twice as much for the same amount of light. A LM561C F-series stripe can be as efficient as a LM301B stripe if you run them at a lower current.

From what I can tell the lm301b and the lm301h are the same diode internally, the lm301h is just part of samsungs horticulture series LED's, which are able to withstand harsher environments (temperature, humidity, and chemical), they also rate the horticultural series in μmol instead of lm. It's Anti-sulfurization, sulfur will corrode electronics.

The cob led lights in this review are pretty decent and would make an excellent choice. Jul 12, 2019 · The drawback can be that a quality grow light with COB LEDs is quite expensive compared to cheaper purple lights. Oct 30, 2018 · Current tech pushes the the light yield way beyond the 200 lm/W levels for Quantum Board chips (LM301b or LM561c).

Depending on who builds the board you are looking at 2.7-3.03 μmol/J for the lm301h. The lm301b tops at about 2.7-2.8.
