Still tried CRI90. You are right, there still less power but grow much better if you compare same efficient. Tried also CRI80 and CRI70. And CRI80 outperforms CRI70 in quality. Sure we had about 7% less yield. But trichomes and potency was more higher than CRI70 (>25%)
I only ask, why you do not...
Sure, but photons of right Spectrum. With CRI70 you get a ton of blue and green photons, but less less red. So why not use only Blue Leds? There you get most photon out.
I checked also first post. I only see Topbin CRI80 at 3000K. The other are second bin. Of course >4000K it is Topbin but only for CRI70. It is not possible to take 4000K CRI 80. Why you prefer CRI70? Do you also use CRI70 in your grows? Or, because CRI70 is more than 30% cheaper? I know prices;)
Right, but why they use CRI70 Topbin and not CRI80 Topbin. Where is the improvement from CRI70 to CRI80? I am sure CRI70 emit less red and other colours.
Maybe Epistar will made better diodes in future, but for this price, they have to use the cheapest one. Cree an Co has also really cheap diodes, but this diodes also not efficient enough for a good grow with same wattage as other Lamps.
So it is ok for you, that he wrote some wrong facts on his homepage? Also the wire of PAR meter is behind rod of tent. Why? Maybe the correct sensor measure some other lights in Background? Looks like a professional fake video.
I do not understand what you try to explain us? In this video are more than 2 lamps. Also this plants have more leaf than buds! This is something you grow last 30 years with your HID? Please stop talking BS. It look like there are 300g on an 8x4 area. I know people make this with 200W and 2x2 area
Looks like, this is a chinese company. Also they use mix of Cree COB and chinese crap COB. Also Cree CXA on their picture have silver contacts. Was CXA AB bin not gold contact? So they use older binning. So they also produce every Lamp you know. Like Kingspectrum etc.
I am sure this light is not...
