Keep trying...
My chips run at 39C at 24-25c ambient and 46C in 32 ambient...in their encloses with holders and reflectors on at 1400ma.
Do you seriously think you're the first one to get and use an thermocoupler? Or that you are somehow ahead of me in anyway? It is the basics, and how all companies, cob or not, tell you to measure Ts temps of chips(ya...I have tested and used more than cobs). Glad you've taken one step up.
Why compare 3500k to 3500k and 4k to 4k? or 3k to 3k?...I have lead you to the water many times already...you can get there again on your own. You can compare whatever to whatever when you have everything to choose from. That is a choice of a grower(which you're not) to make on what they want to use. But to to try and make a definitive statement or even an argument based on someone missing if a clear flaw.
It has nothing to do with who or what chips. It would be the same flaw the other way around. It is that there is missing info of equal status to the cited and used cob.
