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.

kenwstrI have quite some experience with cheaper led strips, but I assume this one will follow the same principles. The LED’s are actually somewhat in parallel rather than just 5m of LED’s in series (that would require way to much voltage) usually about 3 LED’s are in series and then there is a cutting point. every small strip of 3 LED’s are in parallel to the other 3 led strips. Thus all you have to do is cut at the cutting points and then you can wire all the strips of the different shelves up to one power supple in series or parallel (it doesn’t matter)
