Our pre-wired LEDs are nothing but quality. The 12v 5mm flat top wide angle cool / clear white led puts out a nice color that is sure the illuminate your product or project. Our 12v 5mm flat top wide angle pre-wired leds have built in resistors so that they will work with the voltage that they are rated for. There is no need for you to add any additional resistors. The only thing you need to do is add power / ground and they will illuminate. It doesnt get much easier than that.
The 12v 5mm flat top pre-wired leds come with a built in resistor, all connections are heat shrinked in order to protect them and there is sufficient wire lead on all of them.
This single setup works well with the following voltages (you dont have to select a voltage when ordering): 10v, 11v, 12v, 13v, 14v and 15v. We recommend that you dont continuously run them at 15 volts, but they will take spikes as high as that without any issues at all. If you need need them in a lower voltage then these will still work at a lower voltage, but the output will be a little less. You can also ask us for suggestions on resistor selection for lower voltages or refer to our resistor charts on the specific LED product pages that will help with the optimal resistor to use with lower voltages.
