    We already have samples and will let you know. Possibly so. Also have some unheard of LEDs we are working with as well. We will know more soon.

    I have designed a new GrowGreen board for the LM301B but have put it on hold for awhile. Only 5000k LM301B is available to me at this time. I wanted LM301B 3000k and 5000k, and sent money for two reels one 3000k and one 5000k. A reel of LM301B 5000k with 4000 diodes is up $0.02 per diode from $0.04 an increase of 34% with only one spectrum available at this time. I hope HLG does well with their LM301B boards.

    This is outstanding to hear. I need to squeeze the absolute most performance out of my grow on a sqft basis, and using your stuff so far has been the answer to that. Keep us posted!

    This is great news. Now I can upgrade again so that any cost saving benefits of upgrading the last time are totally shot.:|

    are they even worth the upgrade over the LM561c s6 bin? seems a small jump...couldnt i increase the efficiency of my QB panels buy running them softer?

    They say " Highest efficacy: 220lm/W @65mA, 5000K, CRI 80 " 65 mA is pretty low, right?

    It's not that big of a difference. Very small maybe 2-3% when they become available. Not worth upgrading for sure. The other LEDs are for the elite and they are a different animal all together and won't be as cost effective $/efficiency as the QBs are. So no worries.

    Not really not for the money for redesign and increased cost makes the return minimal at best. Just gonna wait for the next train

    i read somewhere than lm301b are less efficient on 2700k-3500k than lm561C on higher current voltage

    Digikey has LM301B based strips listed, none in stock yet. Look promising but they don't have 288 diode 4 footers.... yet.

    There's a source on Alibaba for tape reel and strips LM561c, I wonder if they too will have these and tapereel of the new diodes.

    Is this the elite that @Hybridway is currently testing?

    He is using a prototype. Final units will be somewhat different.
