Hang this super-bright little work light by the carabinerish hook on one end. The side has a 16-element COB LED rated at 220 lumens, plus a 1W 45-lumen LED on the bottom. The whole thing measures 6" x 2" x 1" in matte black with small highlights in orange, yellow, blue or green, and we’ll pick one to match your eyes. Includes a trio of “AAA”s.

Our each here is (5) 5/8” warm white COB LEDs that are insanely bright (think: airport runway) and rated for 1A 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.

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.

The Shape of Cool™ is trademarked. Really. And its owner is Lava® brand lamps. Accept no substitutes, we always say. Usually. Sometimes. Certainly in this case. This Lava® Lamp is 14-1/2" tall with a silvery aluminum stand and tip. It may have clear liquid with red lava; purple liquid with pink lava; or blue liquid with either yellow or purple lava. All classic Lava® colors, so we know you’ll like the one we pick out for you! All include a 25W bulb in the base. UL.

Twist the barrel of this green laser pointer and watch the diffraction lens multiply the dots and spin them in fascinating kaleidoscopic patterns. Perfect for rave parties, DIY discos, or getting kicked out of movie theaters. Guaranteed to make a cat at least schizophrenic. Measures just over 6" long and requires (2) "AAA" batteries which you will have to supply because your cat hasn't learned how to drive yet. 

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.

Our each is a package of (2) darkness-activated outdoor safety lights, each with (3) intense white LEDs powered by a 600mAh “AA” NiCD charged by a 2-1/8” solar cell. Mounted in weather-resistant 4-5/8"dia x 2-3/8" plastic housings with removable mounting brackets. Includes mollies, screws and thumbscrew brackets for mounting to gutters. LEDs are rated for 30 lumens, and will run 6-9 hours after a 5-hour charge. From iZoom®.

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.

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.

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.

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.

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).

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.

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 panel-mount, grounded outlet from Eagle Electronics is rated for up 15A at 125V, and measures 1” square. You’ll need 1-1/2” clearance on the back. Has a pair of retaining clips, (2) spade terminals and a ground screw. UL/CSA.

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.

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.
