This may be more useful to mothers than butterfly people, that being a 3-LED Headlamp by Task Force with batteries (up to 100,000 hours) in the Christmas gift box area at Lowe's. Price: $2.49 with lifetime warranty through Lowe's (save receipt). The lamp is plastic and adjustable (different angles). Cuts off and on by pushing on the light area. Nice adjustable strap. Light weight. For those that have classes, especially night ones looking for things, a few of these in the supply box for loaning out during class time might be useful. Candlepower is not given, only says "super intensive, low energy consumption". I got one. Think it is quite nice especially for the price. An observation and thought to pass on...
