That was great Stink. I think you’re really going to like your new KB’s, did they show up yet? I have two of the 1100watt models, each in a 5x5 and they are very, very impressive. Mine are 3200kelvin, have 10 bars and imeasure 1.11x1.19m (from memory). Otherwise appear identical to what you showed us. I had a good customer experience when purchased this winter and still am by spring. We had a freak(ish) winter storm when my package arrived, and UPS let the package get wet. There was dampness on the one of the light bars. I told KB and without anything more than that, no histrionics req’d, no threats to “tell the world”, they simply up and sent me a second fixture for free, no cost whatsoever and said, “enjoy owning two KB 1100w fixtures, we apologize for the shipping damage”. They both work very well. I was going to buy a second one provided the first met expectations, and if/when I expanded ops, two more. KB will get my money again. I bought the large 1100w thinking that running it at lower power a lot/all the time would really help manage temps in my DWC tent and promote a long, long life. I like to run fans on all my equipment such as airpump and lights to boost longevity and manage temps in tents and lungrooms. I don’t like overpaying, for needless extras, for purple anodizing, etc., and I value quality very highly. I was nicely surprised by the workmanship. You’ll want a controller or at least a wattmeter for setting your heights/DLIs. The Phototone App is of course. v… important if you don’t have a PAR meter. I took the spectral breakdown data of my KB light, this info is detailed on Alibaba or avail. from KB (they have a third party test results doc. you can request), and using that developed an algorithm that would convert a lux reading to par. My lux reading taken with a high quality Nikon lux meter. Both the Phototone app and all aspects of the 3rd party, independent tests lined up well with my results, so I think in this fixture’s case you can place a lot of faith in Phototone’s algo and your results using the app. If you have an actual PAR meter or have any thoughts on these things please consider contacting to discuss. One other item to note, myself and others are having success using this fixture’s red/far red to generate Emerson Effect and run 13/11 flowering photoperiods, and some others I know have used the red/far red control to reduce stretch. They’ve been very good at datakeeping and use sound methodologies so I have a lot of faith in their results. If you experiment similarly, or have questions, again, please consider being in touch, and we can help each other get the most from these fixtures. Best regards.
