Ten electrical leads with an alligator clip on each end. Each lead is about 20" long, not counting the 'gators. Vinyl coated 20-22 ga. wire with a vinyl cover over each clip. They come in an assortment of five colors with two leads in each color. The manufacturer calls them heavy duty but we would restrict them to the light currents and low voltages you will be using in your home experiments. Our each is a set of (10).

This handy iZoom® worklight isn’t for your head or anyone else’s. It’s a worklight for the workshop or yard that has (2) heads, each at 2-7/8" dia x 15/16" thick. One has a single 3/4" dia 200-lumen COB LED with bright and brighter modes, and the other has a 100-lumen 1/4" COB LED with high and low modes, surrounded by (8) flashing red LEDs. Both heads are connected to a 2-1/2” x 1-1/2" mount via ball-and-socket joints, with clutches so you can lock them in position or remove them. Heads have disc magnets, and swiveling J-hooks, and so does the mount, which also has another magnet on the bottom. Positions and light combinations abound. Weather-resistant, and comes with (6) “AAA” batteries. Turn it on and put it to work as soon as it’s out of the package.

Don't wait or it'll all be gone. You get (4) pieces, 11 feet each, of 18-2 wire, polarized, black with a white stripe and eminently discardable spade-push terminals on both ends. (That's under a nickel a foot, cowboy.) Lamp cord, speaker wire, pretty much anything you run juice to.

Magnet wire in assorted colors (our choice). Great for jewelry making, arts & craft projects or any other exotic application. Even if you are just making a garden variety coil or electromagnet you will still find the prices very good.

Wire up those bowling trophies, or just rewire those lamps with the ugly black cords. You get a package of (4) white 18-2 AWG lamp cords, 48" long, with plugs on one end. Cheap, cheap.

Neatness definitely counts. Even in wiring. Especially in wiring. End those electrical mare's nests with this 6-position barrier strip, rated for up to 30A at 600V. Comes with a clear plastic cover with access to the screw terminals and measures 3-5/8" x 1-1/4" x 5/8" with a 5/16" mounting hole at each end. Terminals are in pairs.

Our each is a 56" length of paired blue and red 18AWG wire with 1/4" quick-disconnect terminals on one end and a 3mm center-to-center polarized plug at the other. Also handy as a hook-up wire.

You decide. This panel-mount indicator light has a 5mm red LED in a 5/16” dia x 3/4” deep mount with 47” leads and a 2-pin 5.5mm Molex connector on the other end. Includes wings on the mount to hold it in place. You'll need 20mA at 3VDC for power.

Forget what they told you in basic training, the spirit of these bayonets is to cast a little incandescent light on things, little being the operative word. Little like dollhouses, dioramas and other DIY projects. You pick: the 7/16” dia clear bulb, drawing 150mA at 9V, with a bayonet base; the 9/16” dia yellow bulb, drawing 150mA at 6.3V with a bayonet base; the 9/16" dia clear bulb drawing 300mA at 15V with a bayonet base; or the miniature bayonet base electrical socket for low voltage lamps, with 5” leads and a 1/2” right-angle clip. All of it’s made in the USA for GE.

These itsy 120V neon lamps have negligible current draw and green sleeves over the lenses. Leads are 4-1/2" long with an inline limiting resistor on one. Made in the USA.

Sounds like a Shirelles song, Baby Blue Teardrops, but these are really your standard household current night-light bulb (also seen strung on tannenbaums across the land). Ten watts with the usual E12 candelabra base, with a translucent bluish tint.

Why curse the darkness when you can light these 120V 10W candelabra bulbs in the electric candelabra you build. Which you can do because each bulb comes in a matching socket, dark brown, 1-1/8" tall x 13/16" dia with steel wings to compress it into a fitting. Each socket is rated for up to 75W and has quick-disconnect terminals on the bottom. UL.

Our laser combo pack scores you two pen-shaped 5mW laser pointers, (1) each in stopping red and going green. These colors are also perfect for Christmas, St. Patrick's Day and St. Valentine's Day. Oh, and nautical situations. The housing is flat black or silver with a gold pocket clip and head. The 532nm Class IIIa green light is 5-5/8" long x 1/2" dia, with a momentary-on switch. It's brighter than the red so it's perfect for all daytime pointer needs. The red is 5-1/4" long, and its mellow red light makes it more suitable for board room presentations but we've thrown ours two blocks at night, no problem. Green or red, whatever you do, don't cross the streams. Each pointer takes (2) "AAA" batteries, which are included.

This 7.5A push-button style, aircraft-type circuit breaker from E-T-A, rated for 115VAC or 65VDC, is temperature-compensated from -55 to 125 degrees Celsius. Measures just over an inch deep x 3/4" x 9/16" with screw terminals at the bottom, and has a 7/16" threaded shaft with mounting nut and a boot. Push/pull, on/off activation. Made in Germany.

This is a panel-mount 3-prong grounded electrical plug rated for 15A at 125V, and we're thinking compressor applications. Has a 2" dia face with a 1-3/16" sq x 7/8" housing behind it, quick disconnect terminals and a ground screw, plus a pair of 2-3/4" mounting wings. Just plug your grounded extension cord into it. UL.

Genesis, the 21st century version. We’re kind of not kidding because this is the guts of a super-intense warm white COB LED light fixture that is so bright it could stand in for the sun. Sorry, we got carried away. Let’s just say it’s insanely bright. Sun-like. Measures 3-3/8” dia with (12) 32VDC COB LED lights, clear or diffused cover lenses (our choice) which may need to be reglued and (4) mounting holes. You add the wiring and a cover. A single LED normally sells for $1.50 each. Do the math. Please mount on a proper heat sink, or your new lamp will go out in a blaze of glory. We recommend a dedicated LED driver or a power supply with a 500mA max output. 

These candelabra-base bulbs draw only 2W but put out the equivalent of a 25W incandescent. Will cast a 2700K, yellow-white color at 170 lumens. In a candle-flame shape, blunt top, 3-1/4” tall and not dimmable. Manufacturer says they’ll last 10 times longer than incandescents, which means nine fewer times you’ll stand on the dining room table to change them.

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.
