5:21 removing or adding LEDs will not change the current. LED driver will change voltage accordingly to number of LEDs but the current will stay the same. Of course the total used electric power and light power output will also change. The same mistake is at 6:06 - you regulate brightness by changing current using DIM pin or resistor Riadj value.
Good catch! of course the current stays constant. The dim pin is used for dimming via pwm. At that point I had not decided on controls/psu , I expected 24v but wasn't sure i can get a suitable supply yo drive all 36 LEDs at once. I'm glad we have such knowledgeable users that spot these details!
Great idea Clem, good to see a simple explantation and practical approach towards developing the concepts into hard facts...
Thanks, that's the goal.
Was just about to suggest an interlock switch on the door when you mentioned it in the video.

Shouldn't you first verify your negative consequences of broadband curing? You may be developing something to solve a nonexistent problem.
The case is extremely but can happen, main point is energy saving, and possible time savings depending on the resin used.
