You can see how my LEDs look rather large compared to others. I ordered "Super-Brite" to see how they differed. They are a lot brighter (probalby reduces glow time) but they are not diffused! Big mistake. Now all of the light is projected just through the front of the LED, while I want it to come out of all of the plastic around the LED.


Since I only ordered 50 Magnets (the most expensive part) I decided to figure out another way to get these to stick/stay up somewhere. On my college campus, we have TONS of big willow-like trees that have no leaves right now. I decided if i out some kind of loop on a Throwie that it might catch on part of a branch or something. Below you can see I just wrapped some 550 military cord around the LED. I could never get it to catch anything. I will try fishing line this week and see if it is any better.


Here is what I learned over all from my first Throwing:

-Check a building first to make sure it's not a Engineering test lab inside. :|
-Our campus street lamps are non-magnetic.
-More people than you think noticed the Throwies on the stop light pole.
-Obviously a production line is easier. One person tape, one put LED on battery, then a magnet taper.
-Blinking LEDs will be WAY more noticable and could cause some real stress if Thrown in the right place.
-Only some lights from a auditorium stage are magnetic.
-A stratigicly placed red LED looks like a "hidden" camera.
-Red is cooler than Yellow in every aspect.
-My LED Throwies happen to be very durable. (miss-threw probably 15 times on the streetlight straight up and didn't always catch it. It fell on the asphault. The LED wires may bend, but with a good taper, it will generally stay complete through a lot of abuse.
-Stanbys want to throw them. :)

Does anyone know where I can get cheap led lights?

I found a website but am not sure how trust worthy the site is to purchase from (http://www.superbrightleds.com). Radioshack has some, but they are more expensive.

I'm looking to design a costume with a bunch of these led lights in it so I need to figure out how to affix the lights to clothing. But the first step is finding these lights cheaply!

Any leads/help/suggestions would be greatly appreciated!

To get them cheap, buy them in bulk. Ebay is great for cheap, bulk LEDs from china.

This reply is almost 2 years after your comment, if your still interested try abctronics.com, 1k red or yellow 3mm or 5mm Leds for 26.99

I've purchased from www.superbrightleds.com AND another place called www.ledshoppe.com they both have great deals on "cheap" LED's of all colors. The only thing to keep in mind is these are "low quality" LED's that have poor color consistency... meaning you wouldn't want to use them in a 5 million dollar display because it'd look "patchy". As for throwies, they work PERFECTLY and the price is low! Hope this helped!

check out ebay, I got 50 for 4 bucks. just type in "(size) (color) LEDs", you can do the same for batteries, just gotta find some that aren't from china otherwise ur gunna pay a boatload on shipping.

if magnets are expensive, try with a soft glue or playdough, or something sticky

try stringing on 10 or 15 on 1 magnet ( if strong enough)

what you can do is take a fishing pole with throwie on the end and then you can fling it... with the correct modification...
Mar 15, 2008. 1:01 PMgeeklord says:
when I said "cast" I ment it would be on a fishing pole
Feb 1, 2008. 3:11 PMgeeklord says:
sweet idea!!!, i should try that at night, strap feathers to it, and cast it into my yard. It sould drive my cats crazy!!!
Mar 9, 2008. 2:09 PMgirrrrrrr2 says:
you should make a video of it and post it... becuase that sounds fun...

Nice Idea. Good Tips. Hey.. But What Is The Brightest Led?
May 24, 2007. 10:13 AMkadris3 says:
about the brightest today in 135,000 mcd 10mm white one . 5mm white is 55,000 mcd. there is a 100 degree beam 4000 mlm one and a superflux 140 degree 15,000 mcd white. colored are slightly less. these are all clear and need the sandpaper treatment. they run the gammet of everything you can imagine. about anything in the 4000 to 5000 mcd range should work well. i got a pile fm unclecytheledguy.com
Nov 15, 2006. 1:00 AMmontiet says:
two things, you want your super brites diffused eh? well grab a piece of 80-220 grit sandpaper and scratch em up. you will still get a more directed light as the ones you got are probably 15 degree LEDs as opposed to the 45s. but still, they'll glow for sure. secondly, this is fun, tape a piece of string about a foot or two long between two throwies, then if you're in the city you can throw em up on lights and higher things and they'll wrap right around.

hi , Can someone tell me how long the battery life is of a throwie, either with a Supa-Brite LED or a standard one. Thank you!!

Magents are not cheap. i have been expirimenting and at first i didnt get the right size magnt. it was way more powerful then i thought, so i started using them as can siliences for my montana paint. I just wanna give a special thanks to all you guys at GRL, you people are the best. you have a real atristic vision, balenced with a good dose of michief. way safer than worrying about getting busted with stencil stuff in the middle of a work. BTW your electrograph is cool, but the LEDs stick out too far from the piece for me and it takes to long to do publicly for me.

A few seconds and some steel wool will change your clear LEDs into diffused ones. Just scratch up the plastic housing. Also, I haven;t noticed anyone suggesting Velcro (the hook side) patches for throwies. These will stick to most carpeting, office partitions, clothes, the dog...

Double magnets. a throwie tie the string on it then tape another magnet on the other end of the string. Just a thought

Please don't use fishing line! It kills birds and other animals in many terrible ways when they ingest it or become tangled in it.
Mar 15, 2006. 1:13 PMpurplerecluse says:
What about something like kite string? It's opaque and large enough that birds and animals are less likely to get tangled, and is probably easier on their digestive tract. Plus, I think you should modify the design a little bit - don't have just a loop (which will be hard to get caught on something). Instead have a line with the throwie on one side and something of similar weight on the other side. When the string hits a branch, the throwie and weight will wrap around the branch - kinda like long nunchucks. :-D

Excellent! Would love to her about some of your expreiences. Try double sided tape to stick them up without magnets. Fewer things are ferromagnetic than you would think, right?
