Question

Does the LED come with wires? - by weston

Answer

The LED comes with 2 metal leads. You can hook up your own wires to it, or solder it to a circuit board. If you aren't interested in attaching wires to the LED, you should check out our pre-wired LEDs!

Question

I noticed that the red max voltage is a lot less then the white or green, can you run them off the same power source, I want to run 2 red, 2 green, and about 10 white 3mm LED's, what power source would I need? - by William

Answer

You can run them off the same power source, but you'll need to use appropriate resistors.

Question

is it possible to wire your LEDs into a subwoofer, so that it somewhat gets brighter or flashes when the BASS booms? - by cody (oklahoma)

Answer

I would suggest that you use our Music & Flash Interface.

Question

Does this site have a L.E.D. that is multi-colored and changes on demand? - by Alex (Mount Carmel, Pennsy)

Answer

No sorry, we do not have single RGB LEDs available at this time.

Question

Do you have LEDs available in 1mm, 2mm, or 3mm diameter? I need very small LEDs! - by kyle (canada)

Answer

The smallest size that we have available are 3mm.

Question

Would it be possible to place the LEDs into the wheel wells of a car? If so would the effect be worth the time and effort?

Answer

You could do it, but it would take a lot of time to get a good look. Try using our Flexible LED strips instead, or for more control and patterns , look at the Wheel Well Kits.

Question

I am trying to find a way to make a UV LED light for fishing at night. Top of the line LED Blacklights are selling for $250.00. Is UV LED the same as blacklights. This is so your floresent fishing line will glow at night.

Answer

UV LEDs produce a very similar effect as a fluorescent blacklights. There will be slight differences in wavelengths and how the light spreads, naturally.

Question

hi i have gotten 15 red 10 mm super bright LEDs but i have no idea what type of resistors to get. i want want to wire a resistor to each one but i need help knowing what kind of resistor to get.
- by Jeffrey (Pittsburgh, PA)

Answer

Just look at the product page. It tells you whhat type of resistor to get. It even lets you order them along with the LEDs.

Question

How many 5MM LEDs of each of the following colors can be connected in a SERIES circuit (so as to not require a resistor in series with the circuit) and run from a 12 volt DC source? (a 12 volt automotive battery is actually 13.6 volts, but is considered to be 12 volts)
Red
Yellow
Blue
White - by David (Warrior, Alabama)

Answer

Simple math!

http://www.oznium.com/led/tech

Typical Voltages:
Red - 2.3
Yellow - 2.3
Blue - 3.5
White - 3.5

Factor in the highest voltage spike autos usually put out, which is 14.4 volts. That gives you....

Red - 7 LEDs
Yellow - 7 LEDs
Blue - 5 LEDs
White - 5 LEDs.

However, we encourage the use of resistors when installing our LEDs, to help protect them against voltage changes and produce optimum brightness!

Question

i want to put these in my tc cup holders will i just have an led connected to a resistor and to a 12v power source and they will come on auto and off auto depending on if the car is on or off?
and if i follow the diagram and use a switch
http://www.oznium.com/forum/images/diagrams/9.gif
will the lights still be on after the car is off if i left the switch on?
- by tuan (houston)

Answer

The LEDs would come on with the car's ignition if you found a wire that does the same thing - like the wire that powers your radio, since it comes on when the key is in ACC mode.

If you followed that diagram, yes the LEDs would be on when the switch is turned on, regardless of when the car is on or off.

Question

How could I make the leads stronger? I've been working with some 5mm led's and a couple of the leads fell off, is there anything I can do to make them stronger?

Answer

There's really not much you can do to make them stronger. Moving the leads is the biggest cause of them falling off, so obviously avoid doing that. You can also make them as short as possible, which will limit their movement, thus lessening the chance of breakage.

Question

I'm considering making signals for on my mirrors (they would help a bundle in downtown traffic) so I was wondering if you could post a comparison picture of the 5mm yellow and orange LEDs... I want to get the ones that match some other amber LED bulbs the closest. - by John

Answer

Orange is on top, yellow on bottom.

Question

I plan on putting 12 LEDs in my car in various places. I am wondering if and how many can you hook up to the music interface box you sell here on the site? I tried to hook 4 sets (eight total) cathods to one box and melted it. - by Steven (Alvin, Texas)

Answer

Probably about 75 LEDs on the music interface.

Do not hook 4 cathode sets to it. The max is 2 cathode sets...

Question

What kind of wire do you connect to the + & -?

Answer

Usually, an 18 to 24 gauge stranded copper wire is best. We've got some 18 gauge wire.

Question

I am planning on using some 5mm white leds on a rc airplane. What I need to know is can you wire 20 leds in parallel and still run them on 4.8-5 volts, and still get the same brightness on all 20? - by Richard (Americus Ga.)

Answer

Yes, that is possible.

Question

How many LEDs should I use and how they will be connected if I want to use the power outlet in the house (120v AC)?

Answer

How many you use is up to you.
Connect them to an AC adapter that gives out 12 volts.

Question

Does the size mater (3mm/5mm/10mm)? It looks like you've got the brightness done by color and size is not mentioned. Is there any difference there? It seems like the bigger they are the brighter they'd be, but I want to be sure before spending extra money when the 5mm ones will do fine.

Answer

The brightness is only slightly different. The 10mm LEDs appear dimmer because the light output is spread more than the 3 or 5mm. 5mm is our most popular size.

Question

My power source is 12v, how many green LEDs can I run from this? Would it require a resistor?

Answer

The voltage has nothing to do with the number of LEDs you can run.

The amperage will tell you the number of LEDs you can run.

Each LED draws 20 mA of power.

So... Suppose your source can handle 1 amp of power. That is 1000 mA / 20 mA = 50 LEDs

If you run the LEDs in parallel, yes they need resistors.

If you run 4 green LEDs in series, no they do not need resistors.

Question

I want to install a super bright LED inside the cannon of a RC tank.
My power source is 7.2 volts 2000MaH battery. The leads will connect to the circuit board which will reduce the current to 3.5 V. Do I need a resistor on the LED leads? - by Joe (Bromont, Quebec Cana)

Answer

It depends. You say the output voltage is 3.5V. Now, just figure out the maximum voltage of the LEDs you are using.

If the output voltage is greater than the max LED voltage: no.
If the output voltage is less than the max LED voltage: yes, you need a resistor.

Question

I want to put blue LEDs in my dash and make my instrument panel blue, but I have no clue on how to hook them up. Is there a manual or something I can use? - by Zach (Croswell, MI)

Answer

There is no manual because there are thousands of ways you can use LEDs. Instead, you should browse the forums. You will find wiring diagrams and lots of good info. If you still have questions, you can even post on the forums for help.

It also might help to find a message board relating to your specific vehicle, and see if anyone else has attempted the same thing.

Question

I plan on putting these in my doors. When I wire them in a series, can I use 1 resistor for all 4 of them, or do they each need a resistor? - by randy (Peoria, AZ)

Answer

When wiring in series, you can use one resistor in order to slightly lower the voltage to avoid overpowering the LEDs. However when using resistors, I find it easiest to give a resistor to each one, and wire them in parallel.
