No wonder the PS voltage drops after you turned on the LEDs.. they warm up and reduce their voltage a bit…that's why you see the PS voltage dropping slightly.
My guess is 8 chips per package. If you put a 1K resistor in series on the same supply then that would give you accurate enough control to bring them on at a faint enough glimmer to see the individual emitters under the phosphor. I'l guess a 4 x 2 array.
At about 3V per LED, that means each of the 4 modules should have 7 LED elements inside it, giving you an 84 V drop across the module. Perhaps six surrounding one, in hexagons?
Is it possible to replace a tiny LED in an older torch / lantern with a bigger one?
Should play with some cxb3590 or their new aluminum base COB.
Hi Julian nice video. Try to reduce treble on your microphone sybilance is present on the play back on Android tablets

If you light the LED at a very low power, so it barely lights, you will be able to see the chips inside the packages and count them
love the power supply. but what voltage or supply are you using for the input on them? thinking of getting one myself and housing it as a psu project.
you need a bench power supply
Desolder if possible and check them individually.

Hi Julian thx for the video. Please tell me where you have got the "Beast".
ja set
Can you purchase a 12 volt motor generator

Awesome video as always~~^0^
