This battery powered LED lamp can be used for outdoor parties or in places where outlets are not available. It is about 7 watts and will run for 3-4 hours; depending on the batteries chosen.
LED's used can be found here:
Start by printing the various files. You will need two "uprights," three "cylinders" and one each of the other pieces.
Glue the two uprights together.
Remove the sticky tape and attach the LED lights, five on each side of the uprights.
Insert the upright with lights into the base.
Glue the cylinders and end cap together. You can melt them together with a soldering iron also.
Ten AA batteries (NiMH rechargeable) will be held in the base. Solder the negative battery lead to a SPST switch.
Take a wire from the other side of the switch and attach it to the negative wire coming from the LED module.
Solder the positive battery lead to the positive lead on the LED module.
Push the wires neatly inside the base.
Clip on the "base clip" to secure the batteries.
Place the lamp in a selected spot and turn it on. I used a 3d printed table
If you prefer, the lamp can be powered by a dc power supply, 12 volts capable of supplying 700 mA or more.
