Super-Bright LEDs:
$6.99
This listing is for my Super Bright LEDs in a variety of colors and two different sizes.These items were tested before they were packaged so I will guarantee that you will receive all good LEDs. They are usually packaged by weight so I may have accidentally shipped extras. If so, please feel free to keep them for your next project. If you are not satisfied with your purchase, I will replace it or issue you a refund until you are satisfied. These items are not being shipped to you from overseas, they will be shipped from my shop just outside of Longview, TX so you will receive them in just a few days, assuming the Postal Service is still operating.Please read this listing before ordering, so it will save you some money and perhaps some confusion. If you have any questions at all, please reach out to me so I can help you with your order. Assortment size refers to the total number of LEDs you are planning to buy, not the individual items. So if for instance you are going to buy 50x red and 50x green, then go ahead and order a 100x assortment size. For the color, select assorted and tell me in the message to seller that you want 50x red and 50x green. Current pricing is as follows:50x for $6.99
100x for $11.99
150x for $16.98
200x for $19.99
Bulk pricing available, please ask me!All my LEDs are pre-packed in either 50-count or 100-count packages but you may order any number of LEDs you desire for a color. For instance, if you only want 10x Red, but 40x Cool White, then this is an assortment. Under the Color selection, choose assorted and in the message to the seller, please specify your order. Colors of less than 50x are typically packaged together in a single assortment package of 50x or 100x unless you ask for separation of colors. Think of a bag of Assorted M&M's where you get all the colors mixed in a single package. If you want to sort them out after receiving them, my best recommendation for testing the assortment is to use a simple coin battery. (i.e. CR2032 or equivalent)Current colors available for 3mm and 5mm sizes are:
Red, Orange, Amber, Lime-Green, Green, Blue, Pink, Purple/visible UV (395-400nm) Cool White, Warm White and Invisible Infrared (940nm)Also available are flashing LEDs in certain colors. Flashing cycle is ±2 per second. ColorWavelengthLuminous IntensityInfrared940 nm5,000 mcdRed630-635 nm5,000 mcdOrange615-620 nm5,200 mcdAmber

These are perfect for hobbyists and engineering students. If you are looking for Project LEDs, please visit my listing here: Project LEDs - may also combine these LEDs as part of your assorted mix, just tell me when you leave a message to the seller.These LEDs are standalone devices and have no current-limiting device included with them. The user is expected to understand that these items are not light bulbs and will REQUIRE a current limiting resistor or other device to restrict the current to no more than 20 milliamps or damage will occur. Light Bulbs are resistive in nature and therefore have a set voltage value and their current is set by the voltage running through them. LEDs however are semiconductors and have no set voltage. Like most LEDs they have a forward voltage of 3 or 4 volts, but can run on any supply voltage that's higher than that, provided you also include a resistor or a pulse-width modulator with it. Resistors are cheap and provide a simple solution to your LEDs for proper illumination. But they also convert your unused voltage into heat which is wasted in the end. PWM devices are far more expensive, but allow your LED to consume all the power being provided to it with no waste, no excess heat and no damage to the components.If you need resistors, please check out my listing for resistor assortments below. These assortments are customized by you and can be any value between 1 ohm and 22-megohms. You can order 50 different values or 50 of the same value, mix and match as you see fit, just message me in the message to seller option with a list of resistor values that suit your project. If you need help or have questions about this, please contact me before you buy. I am happy to help you with your project!¼-watt (250mW, 0.25 W) resistor assortments - https://www..com/itm/193813568906
