well the biggest thing is cost. when you can buy a chip that costs half as much as the $50 CXBs of a year ago, and its the same efficiency at 60-70W that we were getting at 50, that reduces your build substantially. bettter thermal management allows for cheaper heatsinks and longer lumen life, etc.
what people were building DIY ffor $3 a watt will now be much ore efficient. that plus better techniques/genetics/nutes/media means 2GPW should be the new standard in a little while
thats another reason i like the cxm22. the 22mm les on a 28mm chip is a super common platform that you can bet will be around for awhile, so a few years from now, you can upgrade to luminus gen 5, citi gen 9, getians latest, etc etc.... it has many holder and reflector options
2 GPW standard soon? I'm still waiting to see people pull 1.5 on a reg. see one here n there but feel it's popcorn counted in, no journal, or just rare & reserved for internet famous people.
Not being dissagreeable, just sharing my thoughts.
As of now, 1-1.2 seems to be the norm considering good grower n plants in a Scrog most times. That's w/ COBs or good white based LEDs.
Now vertical growing, that's another story.
Do you have a picture of this CMX chip?
I read earlier in that it is cube shaped? That would be cool. If so, I wonder if they'll make a special optic for it. That would really spread the light while confining/consolidating it to your grow space.
Interested to see. I just now started reading what all you guys have to say about the new cobs. For those that already built a DIY using CXA's or CXB's, I highly doubt switching chips now is going to improve your ROI electrically w/ a few % & still paying off the initial cob purchase. But for those getting into it now, it's cool to see these options & differences.
I'll read more as i haven't even finished the thread yet.
If it's an actual 5 sided COB cube, that's mega cool in my book. Seen similiar les's in a light about a year ago but they were cylinder shaped & didnt Seam adventagous. W/ a new fancy optic, that could be though.
Staying tuned to learn more.
Great info.
I've used this same lil model to bubble 30 gall. W/ 2 stones several times. Works just as good.
