These are medium-base dome-shaped LED light bulbs, and in standard English that’s a light-bulb-shaped LED light bulb with a standard light-bulb screw-in bottom. These draw a stingy 15.5 watts but throw the equivalent of a 100W bulb. Instant-on and dimmable with a 25,000-hour life expectancy, and also suitable for damp conditions. Your only job is to pick 3000K soft white, 4000K cool white, or 5000K daylight. UL.

Like blue jeans, but for wires. So you can color-code those wires instead of getting all confused. You get a 10-pack of 12" long x 9/32" pieces of heat-shrink tubing, (3) each of white and red, (4) of black. Rated for up to 600V 125°C. UL.

Turn the knob on this battery-powered lantern and watch the trio of 12-element COB LEDs go from nothing to 600 lumens. Measures 8-7/8" tall x 4-1/2" dia with a clear 4-1/8” tall window around the light, which has a folding handle and a bonus compass on top. You add (3) “D” cell batteries and you’re good for approx (6) hours, or more if you dim the light. We’ll pick one in red, blue or green because it doesn’t matter.

Just plug this set of 2-contact flat molded connectors into each other. (Each one has both a male and a female port.) Yes, they're on opposite ends of 10" long red and black, 18-2 AWG leads, but that's just a device to keep them together. When you're ready to hook them up, just clip those leads and get each end wired. You'll get a pack of (2) complete sets, perfect for hobbyists, tinkerers, and electronic DIYers.

There are some things you just shouldn’t look at directly, like the mind of our copywriter, and this iZoom® flood light. The latter is a 10W, 700-lumen floodlight with a 3/4” dia COB LED behind an acrylic lens. The whole shebang is in a 7" x 4-1/2" x 1-3/8" weather-resistant housing with a 3-1/2” handle on top, and a pivoting kickstand. Color temp is 6000K (coolish) and it comes with (6) “AAA”s for power, which is about (3) hours’ worth.

A failed folk-rock group from the Summer of Love? No, a trio of pretty lepidoptera oscillating through many colors via the magic of fiber optics. They have a 3" wingspread and sit on a 1-1/2" dia base that holds the (3) included and replaceable button-cell batteries inside. You'll get (3), at least (2) different, along with self-adhesive tape to stick them somewhere. We like them as party lights, but they'd also be great on a hat.

Don't hide this light under a bushel. Probably couldn't anyway, since it features (24) flashing, spinning, pulsing red, green and blue LEDs. It cycles through a variety of different patterns, looks like it came from outer space, is black or translucent white (we'll pick) and plugs into the wall via a 3-foot power cord. Mounts via (2) keyed mounting slots on the back. Measures 5" dia x 1-3/8" tall at the center. Rated for 8,000 hours of flashing fun. Click here to check out our Facebook post to see it in action.

Or barrier strips, or terminal blocks, depending on where you are and who you ask. Ours is a (4) position x 2 block rated for up 30A. Standard screw-type terminals, and measures 3-1/4" long x 1-1/4" x 5/8" with a pair of 3/16” mounting holes at each end.

You move too fast. You got to make the mornin' last, sport, or you've got no chance at all of feelin' groovy. The Groovy Lamp is LavaLampish, but with clearer fluid that's not quite so goopy, but considerably more, well, groovy. Stands 13-1/4" tall on a 3-3/8" base and draws 25W. Has an in-line switch and 6-foot cord, and we'll pick a blue, green, purple or orange one for you. UL.

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).

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.

This 4-3/4" dia moon is so much more interesting than the real thing. This one has a 4-way dimmer, flash/strobe/fast and slow fade/steady-on modes, plus internal LEDs to make (15) colors in addition to traditional moonish white. It's also a great nightlight. Remote control comes with a battery but you'll need (3) "AAA" batteries to run the moon. Topographical, but the giant astronaut footprint suggests it's not quite to scale. Will sit up by itself or wall mount on a couple of finishing nails.

Itty bitty Edison style 1/4 Watt lamp with a 3/16"/5mm screw base. (type E5 or E5.5) 1/2" long overall it needs 160ma @ 2.5 V. It has a clear glass envelope that collimates the light at the end for greater intensity when viewed end on. Typically priced around a buck a each. Great for science fair projects. model railroading or anywhere tiny light is required.

Could be a really flexible ear of sweet corn, but it’s not. Here’s what it is: a super-bright, 30-element COB light in a 3-3/4" hex x 1-1/2” housing mounted on a ball and socket joint that’s attached to 2-1/2” hex base with a 2.5-lb pull magnet. Ready for hanging on to any ferrous surface, like a fender during a nocturnal tire change, for instance. Throws a hefty 250 lumens and comes with (3) “AA”s.

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.

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.

An 11/16" long x 7/16" ID steel socket for candelabra bulbs. Two tabs come up from the bottom to panel-mount it. Add power through another tab bent downward and one extending out to the side.

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.
