Technics 1200 custom LEDs too bright

Hi there,

I recently purchased custom blue LEDs from here:Pardon Our Interruption... . After soldering everything in i noticed that the 33/45 lights and the pictch fader light are blinding to look at. I know that i can solder in resistors to dim them but i’m just not sure what spec resistor i will be looking for to get the job done and not case any problems. I am by no means an electrician.

Thanks!

The listing has been removed but I guess something like 330 or 220 would be fine.

330 sounds a little low to me.
Did the LEDs not come with resistors?

(Voltage - LED Voltage) / (Current / 1000) = Resistance

Yhea you’re right it won’t be enough, best to set the prefered brightness with an potentiometer and base the amount of ohms on that if you can’t pull up any of the specs

Excuse my ignorance but I’m not even sure what a potentiometer is haha. I do have a multi meter though. Would it be possible to measure the amount of ohms with that and then pick up a resister with about half that amount?

Thanks!

Haha no problem i am the one who should apologise for assuming it.

A potentiometer is a variable resistor, they typically look like this:

but come in all sorts and sizes.

By turning the knob you can adjust the amount of current flowing trough the connected device (in this case a LED). If you connect one of these and measure the resistivity of the potentiometer with your multimeter you could select a resistor value based on that number.

perfect thank you! One more question then. what wattage of resistor should i be looking at? Or how do i figure that out.
Thanks

Oh just a regulair resistor (they are between 1/2 and 1/4 watt usually) they look a bit like this:

You can never go wrong with Pot… Pun intended. Especially if you plan on doing any more lighting mods.
