Well, not giving it to you, but selling it super-cheap. From Velleman® Security/CCTV, this flashing green security light is approx 4” dia at its widest x 3” tall. Comes without a plug but with 15” leads ready to be hardwired into a 12VDC source. Intended for wall or ceiling mounting, the (15) white LEDs inside the green cover will flash and are dome top facing and the base has (2) screw-mount holes, but if green's not your color, the plastic dome unscrews so you can easily repurpose it for your own DIY use.

Our each is a pack of (10) common cathode 5mm dia red/green/blue LEDs. Clear lens, 20mA rated for 100K hour life. 3V supply will work for all. You also get 100 Ohm and 510 Ohm resistors to step down 5 and 12VDC respectively. Luminous intensity is 4,000 mcd.

Our each here is (5) 5/8” warm white COB LEDs that are insanely bright (think: airport runway) and rated for 200mA at 32VDC. Mounted on PC boards from 3/4” to 1”. Marked for polarity, with solder tabs for power. No lumen rating, but don’t stare at them head-on if you like your retinas because, like we said, they’re awfully bright. And as with all COBs, a heat sink backing is also a good idea.

Brand new 2' x 2' x 5/16" aluminum frame LED panel lights. 4000k (Cool white or neutral) and operates on 120vac with the included driver. These panels fit into standard drop ceiling tiles and draw under 40watts of power making them ideal as replacements for larger fixtures. 30,000 hour life span. Did we mention they are dimmable. Super Eco friendly and make an incredible light table. These will require some wiring as the driver just has wire leads and no plug on the end. Approx. 3800 Lumens

We have stumbled across some sweet little LED lighting drivers. They require between 100-277VAC inputs and have outputs of 27-42VDC (40W) and 28-40VDC (30W). Intended to be used with LED replacement lighting. The 40 Watt output driver measures 5-3/4" x 1-3/4" x 1" and has 2 input and 2 output leads. The 30 W output driver measures 12" x 3/4" x 5/8" also with 2 input and output leads. Now go retrofit away!

Clip this rechargeable bike or task light onto the brim of your cap, and then flip it up or down as needed. Has (4) modes: white high or low flood; red high flood or flashing. Powered by a lithium-ion battery that charges in 2:40 hours via a micro USB port. This is the little light you didn’t know you needed until you got it.

Brand new 2' x 2' LED panel lights. 3000k (Warm Light) and operates on 120vac with the included driver. These panels fit into standard drop ceiling tiles and only draw 40watts of power making them ideal as replacements for larger fixtures. Surplus Fact: Driver might be different than photo shows.

That's (5) skidoos better than 23 skidoo, on account of this 22" light strip has (28) white LEDs on it. To ease installation, we've paired it with a power supply driver. Driver measures 5" x 3" x 1-1/2" and is rated at 28VDC. The black and white wires attach to wall voltage, and green is the ground. The other end has a bunch of wires, but the red and black attach to the LED board and the others are for various control functions. But you only need the red and black to run the light strip.

LEDs in assorted colors and sizes for displays, hobbies, robotics, electronics and more.

One byte at a time. Or maybe just a nibble if you’re trying to cut back. A nibble is what programmers call half of a byte. It’s also what the folks at Velleman call this Arduino-compatible microcontroller which has all of the pins as a standard Arduino, but the Nibble is enhanced with (4) built-in buttons and (4) blue LEDS for easy prototyping. Plus, it comes fully assembled and pre-programmed with a memory game. Just plug it into your computer’s USB port and you can start having fun and learning right away.

Here's our reason to dance. These LED spotlight bulbs from Infinite Solutions use only 14 watts, but are 100-watt equivalents. 5-3/4" dia.  and 5-1/2" tall from top to bottom. They are dimmable, have an E26 standard medium base and are 3000K. (Think of the top end of the warm white scale.) and are listed to last over 25,000 hours or nearly as long as The Lord of the Rings Trilogy expanded editions. Now go illuminate your space.

This tiny 3 mm LED sits in a 5/32" x 1/4" x 7/32" black-plastic box with PC board mounts. At 2-3 volts it glows green and draws 40 mA.

This light fixture takeout has (8) 1/16” dia surface-mounted COB LEDs on a 1-7/8” dia circuit board/heat sink. Nominally rated for 1A at 32VDC via a 4mm ID 2-pin Molex connector. Most will have a 3/8” square clear lens over the elements. The lumens are a mystery, but it’s brighter than an MIT physics major. Color temp is warm white.

This warm white COB LED light is awfully cute at 3/8" but don’t let the cuteness fool you--it’s insanely bright. It’s also deeply discounted (normally $10). Mounted on a 3/4” wide 6-leg pinwheel-shaped PC board, it draws 1.3A at its nominal 32VDC, but will work with as low as 24V. Get a good heat sink, too, cuz it can get right hot when it lights up the night. Made in the USA.

We couldn’t think of any clean jokes for this part, so just add your own. Meanwhile, this little, 1/4” dia, bright white COB LED is mounted on a 3/8” square PC board. Requires 70mA at 9VDC. Our in-house Fire Prevention & Ophthalmology Team suggests a heat sink as well as indirect viewing.

Yes, this is the brightest bulb in the box. Our 120VAC 4.8W COB LED bulb casts a warm white color, and connects via (2) pins to a GU10 base. Lense measures 1-3/8” dia in a 1-7/8” dia surround, and the whole thing measures 3-1/8” long not counting the pins.

Cooper Lighting brings you this incredible bronze Crosstour LED indoor/outdoor die-cast wall light. Measures 5-3/4" x 7" x 3-1/2" deep. It's low profile, operates on 120-277V on just 10 watts of power but delivers 720 Lumens and is 5000K. Die-cast door and universal back box for installation. Wet location rated for outdoor use, secure door lock hinge and mounts to a variety of j-boxes or conduit entry installations. Common uses are stairways, entrances, apartment buildings or anyplace you need security lighting. Amazon price is well over $80.

Orange and green glow the (40) 3/16" dia LEDs in the 5 x 8 dot-matrix grid. Housing measures 2-3/8" x 1-1/2" x 3/8" thick and the chip draws up to 50mA at 2.5VDC. Comes with a data sheet.
