Hi, I'd like to use strip lighting like this for a mineral display cabinet. It's a timber cabinet and not much room for lights so I thought an led strip run under each shelf would be ideal. I could maybe hide it behind a thin triangular timber bead. However I don't know anything about controlling LED current and appropriate voltages. If the strip is cut to a fit the shelves, how do I sort out the supply to be compatible with the lower load and not oversupply and burn out the LEDs.
I understand that at a fixed supply voltage, load normally determines current but diodes are semi conductors and don't behave exactly like this do they? I mean, that's not what semiconductors look like to an ohm meter anyway. LEDs seem to require a pulse current to generate high brightness so it's not like normal DC or AC. So is this an appropriate kit for what I want to do (true colour balanced white light) and does it have suitable instructions. I do understand some ordinary electrical things and do some basic PA, car and home maintenance but semiconductors are a complete mystery to me.
