Yes, it does. Not immediately, but over time reverse polarity will burn out an LED. This is the case when you run an LED without a single diode rectifier or a full wave bridge rectifier on AC or DCC current. Both AC and DCC switch polarity from + to – and back again many times per second. The LED will run fine under this condition for 12 hours, sometimes even longer but after time it will dim and burn out if you do not have a rectifier. The rectifier acts as a 1-way valve to only let the + polarity through to the LED. How many LED’s can I wire in parallel? The LED’s we sell draw less than 20 milliamps of power. So check your power source. If you have a small wall plug power source with 500 milliamps of power you can run (500 / 20) or 25 lights in parallel! We have a light board that we bring to shows, there are 38 lights in it and it runs very brightly indeed on our 500 milliamp wall adapter. How about in wiring LEDs series? We do not recommend wiring LED lights in series. We have trie
