100pcs 3mm Red & Green Lights Bi-Color LED Diodes Common Anode Clear Round Lens +200pcs Resistors (for DC 6-12V) Included, Bright Bulb Lamps Light Emitting Diode

I used these to make flickering lights for my plastic jack-o-lanterns. Use one of these in series with 3 plain yellow LEDs and a suitable resistor. The plain LEDs will flicker synced to this one and the brightness is 4X. :-)

I remember buying 2 uv LED for $5 @ radioshack when they still existed around here, so you aren't going to get a complaint from me about these, but i digress.didn't count them cuz there was a freaking lot of them, didn't doubt it was 100 pc, but even if it were 20 short still not complaining, i was just trying to get a couple for a couple buck anyway.-the leads really are longer, i was slightly impressed to see truth to that (mind you they are thinner than some, not complaining)-they are actually UV, made a pack of highlighter look like some wild glowsticks-100resistors?!?! i was going to buy the LEDs any way, but this got me to buy from them as opposed to other sellers-packed well enough for LEDs, anti-stack pouches, labeled 3.3v UV and .25 watt, 430ohm respectively (otherwise i'll throw them in a bead bag from the crafts aisle, forget what they are and have to test them or look them up)thoroughly satisfied with this purchase, don't think i'll need more for a long time, but i'll happily order another color from this seller

I 3D print terrain for tabletop games. One of the objects is a wall-segment with a wall=mounted torch. I used these with that wall to create the torchlight effect.Pros:Price is excellent for 100 pcs.Lead material is very bendable for 90-degree turns. Do not break even with the bend right at the base of the LED.Bright enough to show through translucent plastic without being overwhelmingly bright.So far, have not had any batteries run down (I am using CR2032 batteries)Cons:None that I have encountered.

That colored picture applies only when the LEDs are lit. They are all clear, so you cannot tell them apart if you mix them up. They also have different voltage ratings depending on the LED color, so you have to take that into account for each one.

Add stated product included 100 leds and 200 resistors. Resistors were not included in the package.UPDATE: I was contacted by the supplier who apologized for the error and wanted to correct the problem. Based on their customer service and their desire to correct the problem, I am changing my rating to four stars.

These have a nice warm white color, are pretty bright (even when under powered), but the capacitors that come with these (430 ohm) are too low for the intended application of a 12V power source. Assuming an exact supply of 12V (which often isn't the case), the proper resistance should be 440, and since you always round up (not down as this supplier has), the closest common value would be a 470 ohm resistor. As it turns out, the tolerance on the supplied resistors is not 1%, as the one I used in testing came out to only 420. This compounds the issue and results in a resistor that is a bit hot to the touch and is slightly exceeding its 1/4 watt rating. You usually want somewhat of a ceiling, and the heat these resistors produce is proof of that. If you are considering these for 12V application, calculate the added cost of 470 ohm resistors, as the ones in this package are not ideal. You could probably get away with using these (read "could", not "should"), but might reduce the life of the LED and resistor and you need to account for the heat that is produced (certainly don't shrink tube them or lean them against any other components.)Edit: I did some brainstorming and found a way to use the supplied resistors and waste less energy. If you connect three 430R in parallel it will make it 143R rated for 3/4W. Then connect 3 LEDs (assuming they are 3.2V, like mine) in series to it on a 12V source. Ideally you want 120R but 143R is not far off and we have a nice 1:1 ratio with resistors and LEDs used. We can get it down to 121R by adding two more of the 430R resistors. They have to be connected in series with each other and then that series has to be connected in parallel with the other 3 (that total 143R) and this will make it 121R. But then you'll run out of resistors before you run out of LEDs. I'm happy with 143R which is ever do slightly dimmer.

these are bright many different colors easy to work with just remember to use the resister that comes with each led or it will get to much power from your power source and blow the led out. It does not take much power to get theses turned on plus they are very bright its a win win with this kit plus very affordable. I'm using them for all of my RC kits planes, RC submarines, cars ,trucks, you name it. would buy it again

I bought this LED kit to replace the burnt out bulbs in my OEM switches, and change the color from the boring green to a cool blue ( I re-used the original rubber blue bulb covers with white LED's). Resistors are needed for 12V systems otherwise you just burn out LED's. I couldn't be happier how it turned out.

The green colour and lens placement are very good. (Some "greens" have poor colour.) The red, while colour is good, the light source is not magified by the lens, giving a weak light output. This is OK if you only want a faint indicator. Not good if you want a strong red signal.

These are good. But be careful to do the math on the resistor values, so as not to burn them out. It is easy to happen with these devices: I lost a couple. Also, the colour is true only when viewed head-on, not from the side.

Works great! Easy to use.... I only needed one though... Oh well, I'm sure this will come up 99 more times in my life. Great value!

Good
