Hello everybody I would like some help from someone who is either an electrician or has built an led diode parallel circuit. I’m looking to make good and cheap lighting for an aircraft hanger I’m soon to build. I am looking to buy these… and I’m also looking to buy this so it is powered by the mains… However I don’t know if I need some kind of resistor as I see a lot of circuits have these. On the other hand,I didn’t know if I didn’t need one because the plug allows 12v into the circuit (I believe that’s what 12v DC power adapter means?)and the leds are 12v so are they fine to not have a resistor?? thanks Lummy06

Built myself a resistance soldering rig, and it doesn't set itself on fire! well chuffed! the Transformer is a 10A multiple output jobbie (2V -12V) probably won't go beyond 6V though. all the other bits are regular lab connectores, some of which I have had to modify to take the 4mm² wire. the probe: I used a pinvise, a useless soldering iron, and some 3.15mm pencillead A closeup of said probe the test setup, all wiring is 4mm² All the bits awaiting a proper housing to make it look good, on the left is the steel plate I'll use as a ground plate (used steel so magnets can help with holding stuff)
