They are bright, the positive lead is clearly longer, they mount securely when pushed into a properly sized hole and glued, and the color variety is helpful. I have used them in Bravo Box I designed that plays encouraging sounds, in a Christmas tree with electricity from a dynamo powered by a toy steam engine, and in greeting cards that light up when you press on the front of the card. The voltage required to light depends on the color. The white and blue can be directly lit without a resistor with CR2032 3 Volt batteries. Review: Great replacements for repairing led Christmas lights - My very first few led Christmas light strings that are about 5 - 6 years old had a lot of dead or dimly lit blue leds. Decided to try to fix them with these and glad I did since they revived all of my strings and the blue is brighter than before. My strings varied from 250 to 300 leds that plug straight into 110v. ## Features - 5mm LED Diodes Kit – Includes 100 Pcs 5mm Led lights in a variety of colors. - 5 Colors -- White/Red/Green/Blue/Yellow - Forward voltage: W/G/B:3V-3.2V R/Y:2V-2.2V Max. current: 20 mA - Head Type – Round. - Application -- These LED lights perfect forDIY LED Projects, School Science Experiments, Car Decorations, Signal Indicator, Electronic and Electrical Experiments, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PG84V17 | | Best Sellers Rank | #27,549 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #107 in Diodes | | Brand | MCIGICM | | Country of Origin | India | | Customer Reviews | 4.5 out of 5 stars 1,893 Reviews | | Educational Objective | STEM | | Item Weight | 0.03 Kilograms | | Manufacturer | MCIGICM | | Material | copper | | Number of Packs | 5 | | Size | 5mm | | Theme | Physics | | UPC | 727040387167 | | Unit Count | 100.00 Count | ## Product Details - **Brand:** MCIGICM - **Light Type:** LED - **Special Feature:** Not Dimmable - **Light Colour:** multicolor - **Net Quantity:** 100.00 count - **Shape:** round - **Material:** copper - **Indoor/Outdoor Usage:** Indoor - **Power Source:** electrical - **Item Package Quantity:** 1 ## Images ![(100 Pcs) MCIGICM 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (Multi-Colored - 5 Color) - Image 1](https://m.media-amazon.com/images/I/518GKwV41pL.jpg) ![(100 Pcs) MCIGICM 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (Multi-Colored - 5 Color) - Image 2](https://m.media-amazon.com/images/I/81-FGATxWWL.jpg) ![(100 Pcs) MCIGICM 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (Multi-Colored - 5 Color) - Image 3](https://m.media-amazon.com/images/I/61Y2CdYmejL.jpg) ![(100 Pcs) MCIGICM 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (Multi-Colored - 5 Color) - Image 4](https://m.media-amazon.com/images/I/41ycEx+m0iL.jpg) ![(100 Pcs) MCIGICM 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (Multi-Colored - 5 Color) - Image 5](https://m.media-amazon.com/images/I/413ZdrOdGQL.jpg) ## Questions & Answers **Q: What are the resistances for each colour of the LEDs?** A: To calculate the resistor you need to use for an LED: take your supply voltage, subtract 1volt for the drop over the LED (actually 0.7-1.5 v typical) then divide that figure by .015 amps. (15mA is usually very bright). That figure is the resistor value. Lots of tolerance upwards from that value. (e.g if supply is 12 volts, to run an LED try 11/.015= 733 ohms or more (nearest available resistor value is 820 ohms) **Q: how many led are there?** A: 100 **Q: Can you provide 24vdc to these LED's?** A: Yes but you need the original voltage and current for the LED -OR- a resistor box to bring the voltage up from 0 vdc to the full bright voltage level that is safe for the LED. With that and using Ohm's Law or E=IR you can figure out the value of the Dropping Resistor you will need for a 24 vdc supply. **Q: I am using these to back light a clock. i hooked one of them up to a 9v battery. it fried it. will it stop the frying the bulb if i string 4 or 5?** A: Sounds like you want to string these in series. Add up each LED voltage rating for the color LED and if is equal to or greater than 9v you should be ok. EG: 2.2 + 3.2 + 2.2 + 3.2 + 2.2 = 10.8v should be ok. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Bright Low-Cost Larger LEDs *by K***R on 25 February 2026* I have used these LEDs in many projects and all have worked well.

Decided to try to fix them with these and glad I did since they revived all of my strings and the blue is brighter than before. My strings varied from 250 to 300 leds that plug straight into 110v. ### ⭐⭐⭐⭐⭐ Nice, all LEDs worked fine *by F***R on 27 August 2020* All 120 parts work fine just after delivery, not a over-time or burn-in test. It's not a defused case style, being designed to be used pretty much "straight on". A 4.6 Volt supply and 200 Ohm series resistor appropriate for testing, noticing the lower Vdrop colors were a bit brighter due to the higher current. The colors are nice - I especially like the pink. A good buy if you are looking for a variety of 5mm colored LEDs for projects. ## Frequently Bought Together - (100 Pcs) MCIGICM 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (Multi-Colored - 5 Color) - monochef 2pcs Copper Tape with Double-Sided Conductive Copper Foil Tape Self Adhesive EMI Shielding Stained Glass Supplies Soldering Electrical Repairs Paper Circuits Grounding, 1/4inch - LiCB CR2032 3V Lithium Battery(10-Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/417776897-100-pcs-mcigicm-5mm-led-light-diodes-led-circuit-assorted](https://www.desertcart.tw/products/417776897-100-pcs-mcigicm-5mm-led-light-diodes-led-circuit-assorted) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-06-27*
