Finished - Advise Please on DIY LED Light

Well, I did manage to follow step by step guides found on the net on how to wire up LED's for baja DIY style.... I had it lighted up through the charging port of rx box, lighted up well, but after charging the rx pack and tested again the light pods, boom...... busted all LED's...... so 6V is too high for the pods, did not install any resistors at all....... will a 4.8V will do the trick? Thanks.

leds are meant to have a 3v power supply. so you have to have 2 in series for 6 volts or use a resister to have one on 6v
 
how can i make a series conenction? What I did was, i soldered all negatives together, positive togethers...... what type of connection is this? Thanks, no idea at all when it comes to circuits,hehehe. thanks. Hope someone helps and guide me......
 
in one light pod, there are 8 white LED's on the outer pod and 4 blue's in the inner.... can anyone suggest how should i connect this out? The array calculator does not have option of combination LED with different voltages....thanks.
 
take 2 leds and connect the positive from one to the negative of the other. do this 6 times then connect the pairs together like you did. the way you connected them was called a parallel circuit.
 
Thanks, looks like i understand it now...will try it again, two LED's connected making six pairs, then connect it again as what I did initially....it will make it 6V for one light pod? Is that correct sir, thanks.
 
Firts pod done as directed.... sweet......not busting anymore when connected to the charging port..... well,just one more question though, will four light pods greatly affect the run time of the rx battery pack? Will it drain considerably?

Thanks, three more pods for the 5T.
 
Hi, got it going already... DIY 6 pack nimh (flat pack) energizer AA batteries and light pods, I got two pods running at the moment, two more to go......

looks like awesome work on the pods nolivy.

killer resisters are not nessesary on a series set up. i watched and read many led tutorials before discrediting your info. your site was the one that taught me neg and pos on the led lights.

What site? Who did the tutorials? Years ago I might have done it like that but not anymore. I've learned a quite a bit more about LEDs. Without resistors you risk overdriving the LED with a fully charged battery. The forward voltage rating is TYPICAL and can vary from part to part, so while some LEDS may work fine just connected to a battery of the proper voltage, others will be overdriven and be destroyed. A small increase in voltage can produce a large change in amperage and make the LED overheat. This is why lots of homemade LED lights burn out or get dim. It's fine if you make homemade lights but you should add current limiting resistors. Do not use your non-resistor LEDs with a light controller.

But what do I know? I only make LED lights and LED light controllers for a living. LOL.

Thanks for the appreciation guys, and i will see how long this gonna hold up, if it wont hold long enough, i will be putting up resistors or possible get the killer DIY light kit, btw, off topic, can i pre order the super killer bee? Its still in back order in your site, thanks.
 
The finished product........let there be light.....

All negs together and all pos together is a "parallel" circuit. It is not recommended to connect LED's in this way. Series means that pos of one goes to neg of the next. continue the string until the desired number is reached. Your final connection points will be the neg from the first one and the pos from the last. Remember to calculate the total current draw so you don't exceed the maximum current your power source is providing.
There are many tutorials online for the various connection methods for LED's and the math formulas for calculating current. Hope this helps.:cool:
