I got my shipment of LEDs from Hong Kong today, well, picked it up atleast. 100 blue and 100 UV. The blue are 3mm and the uv are 5mm. I spent around 35 total I believe. Picture attached, I would suggest buying from these people if you can. I will post link soon once I can get into ebay from home. Edit-me: http://www.stores.ebay.com/chiwingledproductshop/plistings/list/all/dept1/index.html That link will take you directly to normal leds in their shop, its a cheap price, with free shipping. Next up placing these things in their respective places, my new UV light and modding the crap out of everything else with my new-old/i've had for a week or so dremel tool.
I have purchased several hundred LED's from them as well, I don't know if they would get classified as super bright, but they are very bright, and have great colour! Love the colour of the green ones. In my experience they where a very good company to deal with.
Look closely to the LEDs. There is some sort of "bubbles" effect inside, pretty cool I think I got 25 blue LEDs and a keychain for US$9
Led 3000 mcd's 3 mm. Can anyone tell me how you can connect three of these (Blue) to the fan output of the mother board (12 V). Or do I have to use a resistance??? Is the long pin on the LED the + side??? many thanks
If I recall correctly paypal is all that they are excepting at this time. Props to them though, their shipping from Hong Kong to Canada has been amazingly fast!
Don't they have a home page? I would like to buy somehing from there, but I don't need 100 identical LEDs...
Not that I am aware of, just there Ebay store, they have been carrying the odd smaller lot (ie: 25 or 50 LED's) mainly blue and white though. A Yahoo search, only points back to their store on Ebay, so I imagine that is all there is at this time.
You can email him: cooler08 cwithk@netvigator.com For custom orders. They also have UV LED's that are same price as blue LED's.
i have a few ideas questions first how many of these 100 LEDs are actually functional? and now for the idea, get one of those (fairly big) 12v batteries, and solder a huge UV LED sphere around the battery, with a small switch, then flick the switch and throw it into the bus station, lol! blind everyone anyways thats a pretty sweet deal
Now that's cheap.. i have to buy from microplex (norwegian shop) to get that bright leds.. but they are EXPENSIVE! i could order from elfa of course.. but not that cheap.. and they don't carry THAT bright blue ones.. they do have 11000mcd yellow ones though..
Zappy should use these for his chess modding project save him quite a bit a cash or did uhe use bi clour LEDs anyway i wouldnt mind having these but it says the forward voltage is 20-30mA so what value do u take when working out a resistor value? and also how is the quality on these things? do all of them work? or are some dud
"forward voltage 20-30mA"? mabye forward current? anyway.. you need to know both voltage and current to find the resistor... then you tahe supply voltage (minus) LED voltage then you get the voltage over the res.. then you devide the voltage over the res with current... example: LED voltage 3.6 volts supply voltage 12 volts LED current: 20mA 12v-3.6v=8.4 volts. 8.4v/0.02=420 ohms
I've used about 20 of them in various projects and haven't come across a bad one. I've blown a few, but no doa's...
wow surprising considering i ordered 20 from eLED once and 7 or 8 of them were duds these were blue too, they cost me a little less than $4/ea back when i got them...
Ouch!! that hurts the old modding budget when that happens You know, if you are after a smaller lot, maybe you have a mate that would be intrested in going half and half on an order of them with you or something?
