Here is a tower-like candelabra, which has a housing for an LED and coin battery (both supplied by purchaser). While the piece is lovely and interesting on its own, a shade is available, sold separately, in the shop to diffuse the light and provide more character.
Directions for assembly:
When you look at the housing where the coin battery slips in, you will notice that there are three supports that define this space. Two look the same, and one looks a little different. Let's call the one that looks different the "back support".
Get yourself an a standard 5mm LED. Any colour is good - your choice. For the brightest, I would recommend a super bright white or an ultra bright white. But for fun, know that blue and green LED's look very nice with the moon shade if you have bought it also :) Notice that one of the wires coming from the LED is longer. This is the "positive" wire.
Insert the wires of the LED down through the top hole in the candelabra, and wrap the "positive" wire around the "back support" taking care that it is placed so that it will only touch the battery at this place and no other.
Bend the other wire in a such a way that it will touch only the topside of the battery.
Get yourself a 2cm diameter, 3 volt coin battery. The ones I use are described by this code: CR2025. Insert this battery, negative side up, into the LED Candelabra housing.
Your Candelabra should immediately turn on nicely! Note that you can slide the battery slightly away from the back support and this will turn the light out.
If you have purchased the shade, this is very easy to twist on. Simply drop the shade down allowing its slots to slide over the three housing supports. Then twist the shade to secure it fits tightly.
