icon Task Light


This task light is designed to be supported over the back of the neck. It uses 8 cells and runs at 55 ma on high and 18 ma on low. 2 sets of 4 parallel LEDs are in series.



Silicon rubber was used to hold the LEDs and PC boards to the battery box. This unit as was built does not give enough flexibility to adjust the position of the LEDs and at the same time allow the battery packs to rest flat against the body. I recommend a 12 gauge short wire stand-off so that the LEDs direction can be adjusted. This next unit is a night light using minimal power. The battery packs shown in this report can be purchased from your local Radio Shack.



One charge of the cells will last (turned on full time) about 4 to 6 days on high and 1 to 2 months on low (1000 ohms) depending on the capacity of the batteries used.
