    Help with an LED light upgrade

    @G$Dolla Good to hear from you - feel free to email me direct at dan@highgrovelighting.com for assistance. Briefly, we have ceased the COB lineup a few years ago - unfortunately I do not have any old stock else I'd offer to build you one. The part # for the COBs is printed on the white...

    Folding LED Grow Lights

    Pretty sure they don't make one that folds like this one does: https://highgrovelighting.com/cypress-evo-8/

    LM281B+ vs LM301H EVO

    Hi @Rocket Soul Yes - you are right on. I did not want to further convolute the decision tree, however I did inadvertently create a false binary, I appreciate you pointing that out. There are of course options to add discrete spectrum the way others do, however we want to keep to the basics...

    LM281B+ vs LM301H EVO

    Hi RIU, Looking for some more grower input and hoping if you are reading this you are willing to lend a hand. We traditionally reach out to the growers we work with and admire the work of in order to solicit feedback on what works, what they like, and what they would like to see in new models...

    LM301H vs LM301H-EVO

    I concur - I think most would agree that is the smart approach.

    LM301H vs LM301H-EVO

    Makes perfect sense, thank you so much for sharing. And good choice in equipment - HLG makes good products and Steven and Amit (the principals) are both really good people. Have you considered running 660/730 nM boards as a separate item with separate controllability, or do you prefer the QB...

    LM301H vs LM301H-EVO

    If you don't mind me asking you, solely as a grower, what kinds of new combinations are you considering? And what is your motivation? Thank you in advance - I think that the technical points raised thus far are super valuable. Equally valuable, is what the grower is looking for and why.

    Anyone heard of Fluence Spydr i2 LED???

    If the price is as good as you say my opinion is hop on that deal! That’s a good light and a good fit for your grow area.

    LM301H vs LM301H-EVO

    Hello @cdgmoney250 Good of you to stop by and thanks for the post. I agree regarding pushing plants to PPFD as high as they will tolerate. Outdoors on a sunny day PPF levels top 2000 µmol/s easy. As long as the other variables are dialed in then the amount of activity at the photoreceptors...

    LM301H vs LM301H-EVO

    Another really insightful post. I agree with you and this sort of lends an ear towards how the grower interacts with the equipment. This speaks to the largesse of the ability of the light to perform regardless if it is in the hands of a spectral tuning wizard using it or a grower who is simply...

    LM301H vs LM301H-EVO

    Thank you for posting. Clearly lettuce is not a C3 annual fruiting nor flowering plant like cannabis. Wildly different life cycle. Good intel nonetheless as it underscores the fact that LED manufacturers may say they have a horticultural chipset however it is largely developed for the...

    LM301H vs LM301H-EVO

    Spectacular feedback thank you. Very valid point about the ability to increase overall photon flux without having bearing on spectrum. I agree with your point about separate supplemental lighting - it is an addition rather than a deletion, and gives superior controllability from a spectral...

    LM301H vs LM301H-EVO

    I am not espousing the use of discreet blue diodes, rather the discussion is around the use of a white spectrum SMT diode that has certain wavelength I appreciate your positions however there has been a ton of testing pointing to the benefits of LED over HID The point is not to reproduce HID...

    Samsung has done copious amounts of testing including flavonoid production on non cannabis devices plants - here is one such example: https://image.led.samsung.com/content/samsung/p6/led/insights/insight-detail-20/Samsung_Horticulture_Technical_Brochure_190627.pdf I am unaware of the Samsung...

    LM301H vs LM301H-EVO

    Hello @Prawn Connery It is great to hear from you. I have enjoyed your posts and you are a great source of information regarding LEDs. I concur regarding your points on the subjectiveness of the use of words like “better” because growers may be trying to achieve differing results depending on...
