I am build an overtank lumminaire for my aquarium, and it will take some 360 leds, as follows:
Power supply 32V 1,5A
6 strings 10 leds each, at 98-100 mA each - 6 LM317L in current regulation
30 strings 10 leds each, at 19-20 mA each - 30 LM317L in current regulation
So, stupid question nr. 1:
Can a commom resistor set the current for a number of LM317Ls, i.e., for the ones regulating current at 20 mA, one single resistor...?
...and, stupid question nr. 2:
Can the capacitor shown here https://www.electro-tech-online.com/attachments/lm317ireg-jpg.30908/ be a single one for the hole circuit, or should it be one per led string/LM317L?
Thanks for all the kind help you can provide!
Best regards,
Daniel
