I'm working on a project where I need a pinpoint source of bright white light that will be continuously on, so it needs to be plugged into a wall socket. I don't have any electrical knowledge, hopefully someone here can give me advice on the easiest/cheapest way to do this.
I see there are LED lights on ebay (such as this one: http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=180485485402#ht_2853wt_941)) and I have a few extra power adapters lying around. Can I just connect the power adapter to such an LED and plug it into the wall?
The LED lights I'm seeing have specs like this, but probably vary a lot:
3.5V~4.0V or 3.8~4.5V, etc
700mAh
3Watts
One adapter I have from an old cellphone has this output:
5.0V, 0.7A, no word on watts.
What would I need to do in order to power the LED light? Can I just attach the wires from the adapter to the contacts on the LED? If I'm thinking about this the wrong way, any advice is greatly appreciated.
Thank you!
Paul
