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.

Yes, the sun already lights your yard, but with this set of (100) solar-powered white LEDs, it will light up the yard at night, too. On a 40-foot cord attached to a solar cell and a NiMH rechargeable battery, it operates in steady-on or flashing modes. Eight-hour charge cycle. Internal sensor detects ambient light. Includes mounting hardware, mollies and a 7" mounting stake. Great for modeling or doll houses.

Sometimes there’s nothing for it but having your own plasma ball. This is the travel- or office-size, a manageable 3-1/8" dia acrylic ball standing on concentric blue disks, 5-1/4” tall altogether. Lay hands upon it and watch the soothing red and blue streamers wave and undulate your troubles away. Great for disco or psychedelic raves in your car or cubicle; you supply the soundtrack. Also great for just strapping to your head to make sure people look at you at music festivals. Get creative with it--take it everywhere you go. You bring (4) “AAA” batteries.

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. 

Like the smartest kid in class, this little PC board is crazy bright with (8) 1/8” dia warm white LED COBs. Clearly marked pads for power inputs. The whole shebang is just 7/8” dia with 3/32” mounting divots. Requires a heat sink and a current-limiting resistor.

Who doesn’t love laser pointers? Their precision. Their ethereal, mind-blowing, otherwordly glow. Their magic, now-you-see-it-now-you-don’t quality. Ours come in several colors, including red, green, violet and combinations of those. You want a single point? We’ve got ’em. You want a kaleidoscope display? We’ve got those, too. They're all 5" to 6" long, give or take, and batteries are included. All you have to do is point and click.

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.

This Rechargeable 1000-lumen floodlight/Phone recharger from iZoom® has the power to be a real retina-scorcher. Throws a warm white light from the 1-1/2” COB LED inside a 2-7/8” x 2-1/2” reflector that draws 10W. Its powerful Li-Ion battery will last (3) hours on a 5-6 hour charge. Housing is 6" x 3-5/8" x 1" with an easel that separates, so you can hang it on a pipe or rod. Comes with a USB adapter and a 3-foot cord. As a bonus even has a 3600mAh USB-out to charge other things like cell phones and tablets! Includes a high/low/off switch, and is listed as weatherproof. Yours will be red or yellow, not that it matters.

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.

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 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 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.

These great little indicator LEDs are wired with an in-line diode on one leg so you can run them with either AC or DC. 12-24 volts works best (do not run them on 120V!) drawing 4mA. You'll get leads between 4" and 9" with quick-disconnect terminals. Because these are pre-wired no fumbling with tiny connectors! You pick yellow or red.

And vice versa. Luckily, you’ve come to the right place, where we’re pairing clear glass 2.2V, .25A wavy, flame-shaped candelabra bulbs, 1-1/2” tall x 5/8” dia, with matching steel sockets, 11/16" long x 7/16" ID, with (2) power tabs. Sockets have a pair of clips for securing them in the light fixture. You’ll get a package of (5) bulbs and (5) sockets.

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.

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).
