The biggest surprise in this unit was the massive variation between LED currents. The older technology yellow passes over 12 times as much current as the green LED, but still looks dimmer.

This cost a mere £3 from a local store, and would make an excellent project case.

Cheap cordless wall light - perfect as a project case

This unit is powered by three AA cells, but could be hacked to a USB supply. The manufacturer has tried to intensity match the LEDs with the result that the green LED is powered at a very low 3.8mA, while the yellow LED is being grilled at 150mA even though it's still much dimmer! A set of identical colour blue, green or white LEDs would improve battery life greatly, while still being a bright and useful light for adding a touch of style on a temporary basis. An interesting twist would be to make the unit rechargeable, as it has loads of room for lithium cells. Although this light came from a UK High-street store (One Beyond), it may be available from other sources. At £3 the price is worth it for the case and lenses alone.
