If all of your bulbs are LED bulbs, would it make sense instead to have a $12\text{V DC}$ circuit for lighting around the whole house and LED bulbs without the per-bulb conversion? Since we have 32 parallel connections means the total consumption will now become 32 * 0.06 = 1.92 watts, still pretty much reasonable. OK, but I'll also need to know what supply voltages these two lamps used…only then I'll able to judge the LED specs and then accordingly would be able to tell you the resistor value and the wiring detail for connecting these together with a 12V supply. Only 3 left in stock. As I want to use 9 parallel led of 1.2 watt and want to operate circuit at for 12 volt battery source led spec is 9- 10 Voff and 120 MA current please tell me what change is exaxtky required and Lm 338 required heat sink or suggest any other good ckt for different combination like strings of 4 led 3 volt Voff and 3 parallel series of this . However connecting in parallel would mean multiplying current. For operating an LED with a 12V power supply or battery use minimum 560 ohms value resistor, or you can also use 1K maximum value. Livraison gratuite . When two Light-Emitting Diodes are connected, the first LED diode will conduct in the negative semi cycle of the wave and the second one will conduct in the positive semi cycle of the wave. Contactez-nous pour les produits LED de haute qualité au meilleur prix CDN$ 21.99 CDN$ 21. LED indicator lights offer a lower current consumption and longer lifespan than incandescent lights, but are less tolerant of voltage fluctuations. is it the same process if i use different color of led light for my lantern? Provenance : Bulgarie. Project page: Simple Basic LED Circuit. The 12 Volt DC spotlight with a current draw of 200 mA (2.4Watt) has an illumination of 130 Lux within 1m distance, the equivalent of a 20 Watt halogen spotlight. R1 is a must in the circuit to bleed the stored current from C1 when the circuit in unplugged. This is a 555 led flasher circuit this circuit will blink many LEDs and give rotating effects.

Each of the shown Two LEDs with the series resistor becomes one string, count how many are there. Unfortunately, time is of the essence here, and I won't get the 150ohm resistors in the mail before the project is due. Ok thanks, if does not work I will just build one of your Emergency circuits thanks Buddy, Thanks for your reply, I did miss something I thought all white LEDS had the same (ma) rating and voltage draw, I told you I know just enough to get my self in trouble, I guess it is going to be trial and burnout method, they are free now and if I can not make them work I was going to throw them away anyway, going to hook them as they are to a 5 volt phone charger first to see if they burn or burn HA HA, it is never easy when you are trying to recycle free electronics< if you do not snap, crackel and pop you are not learning, that is like I crashed 3 computers before I learned how to use dos and now you use windows do not need dos, thanks Buddy, sure buddy, you won't learn unless you sacrifice a few of the valuable things…, you can experiment on a single LED, by applying 12V to it through an arbitrarily selected high value resistor such as a 1K, then go on reducing this value until you find the resistor getting to hot or may be the LED on the verge of getting destroyed, this will tell you which value of resistor was actually optimal during the procedure…, thanks for the help, So I am confused if you have an white led with a 32 ohm resistor you can not just add another resistor to use with 12 volt batt, what about just taking that resistor out and just replacing it with one that works with 12 volts, I think I will make it easy just cut that resistor out put in a jumper in to connect two LEDS and put in the resistor you have shown above and be done with it, what do you think, or am I missing something which is almost all ways, thanks for your thoughts, buddy.
