Nice work. For the 72C@1400mA, what does Tc read? Pretty sure the individual LEDs will get pretty hot, but wondering how this relates to Tc as the remainder of Bridgelux's data is wrt this.
Also, curious about the OSH park PCB in your profile.. the LED pads and the ESP make tell me its some...
great work. Looking forward to seeing your light and how it integrates. Are you an electrical engineer or hobbyist? Everything looks well thought out and professional. Also, what are you programming the firmware with?
this is very cool. Care to explain the components and functions a bit more? What is reboard #1? does the ESP setup a webserver to display the data or is it cloud based? Also, is the camera/video transmitted over WIFI or just the screen?
thanks!
Correct, based on the data. For free module droop measured was somewhere b/w 0.4-0.5v. Starting voltage was 23.3 and stable between 22.9 and 22.8 (resolution of my power supply). Interestingly, numbers measured were close to what Bridgelux says they should be (0.0095/*C)
Did some experiments with respect to droop and temperatures and wanted to share results- This is for a 560mm 4000K Gen 1, might be useful information for those looking to get more information about cooling/running temps etc.

Learnt a lot from this board while researching building an LED fixture for growing 'conventional' plants, and I'm excited for the opportunity to contribute in this thread.. Setup is a 4x4 with a quad Vero 29 gen 7's running @ ~320W from the wall.
