100pcs 5mm Red Lights LED Diodes (Red Lens) Diffused Round Lens 29mm Long Lead (DC 2V) +100pcs Resistors (for DC 6-12V) Included,Bulb Lamps Light Emitting Diode

Summary - Nice pack of LEDs to repair Christmas lights Pros - Common colors, good for Christmas lights - 20 of each color - Good price Cons - Base of light is wider than the light, so it doesn't sit down in the Christmas light base I used these to repair burned-out LEDs on several strands of C9 Christmas lights. I like the color choices, as they are common to most Christmas light strands. Mine are red, orange, yellow, green, and blue. This pack contains 20 of each of these colors along with 20 white and 2 packs of resistors which is a nice bonus feature (but not useful for repairing my Christmas lights). These function very well, my only minor complaint is that they do not sit snug down in the holder for the LED like the original ones. They do stay in place relatively well once you bend the wires around the base. Speaking of wires, they have a very long wires so once you bend them in place, you will need to snip off the excess. But... Make sure you don't snip off too much or the LED will not have proper contact and won't light (I found this out the hard way). These are very bright and the colors are true. I'll be buying them again. Overall I am very happy with this purchase. If this helped you, please consider giving it a thumbs up. Thank you.

I only needed one for a project but ended up buying this as I can always find a use for an RGB LED... I have purchased other EDGELEC products and they have seemed to be well packaged and work. These are no exception. So far, not a single dud in the package! They are definitely brighter at higher voltages (as expected), seem to like 5vdc the best but include resistors to use at 12vdc should you need to do so. A bit dim at 3.3vdc but there are use cases for that type of brightness, YMMV. Great value and appear to be durable. I probably have a lifetime supply but if I ever need more, I know where to get them.

I used a solid 12-volt power for the base, ran the power to a bucker to kick it down to 2.2 volts, went through a DPDT pushbutton, installed one of the included resistors on the red leg (the longer of the two) then by pressing the button on the switch, quite readily flip back and forth between red and green.

Very nice LED using as red H green L In logic circuits buffer drives Red inverter drives Green really makes data buss and address buss easier to read any other device output is much easier to understand. Blinking LED’s are the best.

I tested these up to 18 mA and they are bright enough to be uncomfortable for direct viewing. These have a nice diffused warm color to emulate incandescent lamps. I burned one out immediately at 29 mA so I recommend not going above 20 mA. ALWAYS use a current limiting resistor!

Great selection for the project i am working on.

solid haven't found any bad ones yet

Favorable remarks: neatly packaged and a tested set of the components appeared to perform as specified. I tested with continuous current at 12 volts through each anode, using the supplied resistors: 470 Ohms for red and 430 Ohms for green and blue. The individual colors were very distinct. Then I energized all three colors simultaneously. The RGB LED then gave a very bright, cool-white light. Current consumption remained steadily near 60 milliAmps during test period of 2 hours. Conclusion: I would feel confident using the products supplied at voltages up to and including 12 volts. However, the resistors became very hot. The reason may be that they are rated for 1/4 Watt = 250 milliWatts. For comparison, 20 milliAmps x 12 Volts gives 240 milliWatts. The resistors are being pushed almost to the upper limit of their specification. It seems prudent to think about ways to increase the margin of safety. For continuous operation at 12 Volts and 20 mA I would consider replacing the supplied, 1/4-Watt resistors with more robust, 1/2-Watt parts. Other alternative approaches might include reducing the supply voltage or pulsing the 12-Volt current using PWM.

Tel que décrit. Bon rapport qualité prix. Arrivée rapidement.

Pour ajouter à vos RC du réalisme beau bon pas cher sur que c'est plus long que d'acheter des kits tout faits mais tellement moins cher que ça vaut la peine tous mes rc sont équipées de lumières de ce genre et je suis très satisfait du rendement et de la durabilité je vous les conseils fortement le range de 3v a14v est idéal demande un peu d'équipements dextérité et patience mais un coup fini le résultat est très satisfaisant.

Exactly what I ordered. It is nice to have LED's come with their respective resistors. The LED's blue LED's are what I ordered and they are nice and bright using an 18650, 4000mAh 3.7V battery.

They like they are suppose to.
