So $800 to cover a 2x4 square when you literally have to make the light yourself?? And that is just for parts. If someone started to sell these "64% efficient " fixtures to cover a 4x4 space it would cost approximately $1500-$1600 just in parts. So assuming you didn't do work for free, or sell...

On a side note, since there is a lot of talk about the XB-D chips not being that great, I did some more research in the "Binning and Labeling" Doc. on Cree's website . While there are certainly more efficient options, the higher bin XB-D's (group code Q4-R2) can put out up to 112 Lumens/Watt...

Cool, so to get 5000 lumens efficiently you have to spend $88-$114 just for the COB (CD & BD bins Mouser) let alone the heat sink and the driver. Even if you went the cheaper route and got the lower bins from KingBrite, you still have a hefty investment to make for a high efficiency panel using...

Incorrect.... XBD is the "series" of LED chip (i.e. CXA, CXB, XM-L2, Vero 29) Within the series of chips they are then grouped into "bins" which are chips that perform similar to one another. That is why you can have a cheaper CXB3070 for $40 (AB bin on mouser), but a higher bin CXB3070 will...

^^^ I'm not sure these lights were designed with the intention of covering a circular shaped canopy. Most grow spaces I've seen are squared in the corners, i.e. 4x4 tents, basements, bed rooms.. etc. Also, if the par/lux measurements are only adequate in the center beam of the light but degrades...

Taking Ass and Kicking Names

I will be doing this in the coming weeks. Not paying for it, but I will do a 4x4 test with par readings, see what the footprint really is and average ppfd. Hopefully that will put all this speculation to rest. Looking about 3 weeks or so. Btw I think we are getting an SK400+ with the 90 degree...

1.21- so where do we draw the line on speculation? If nobody has a par meter for the HB and a watt meter to calculate efficiency what can we really discuss here? Other than opinions on the creator or opinions on the design. Oh wait.. If you can read a data sheet apparently you know exactly how...

Wow. Now I realized why I never posted in the 7 years I've been a member. I even use CXA's for veg and have 40 veros going to my other side of my flower room, but now I feel like such an outcast and a "shill" whatever that means, that I don't feel very welcome at RIU. Sorry if you don't like the...

I've read through all the hate mail too. This doesn't show that the product doesn't do what it claims. And if anybody Youtube's SK vids from the past 4 weeks, it pretty much disproves the whole hate novel. Can anybody provide a video of seeing the light in person and it not performing?

Not sure the relevance of how often I post... guess that means I'm a newb. I don't know how to quote people yet.. So my bad I always get Apache and Area-51 mixed up because of the RW fixtures. My mistake. Probably discredits everything I'm saying. But referring to SK question... I don't know...

I think this is my first post ever.. been watching the forums for a long time. So.. Which model did you choose? 300, 400, 400+ maybe? Which reflector angle did you use? 60, 90, 120 maybe? What area are you trying to cover? What wattage Gavita are you running? I'm not defending Spectrum...
