The Light That Doesn't Fail

Rayovac Corporation's Luma 2 flashlight incorporates NASA's systems redundancy. The company also received assistance from NERAC. The flashlight has an extra-bright Super Krypton primary bulb and an independent backup system including a separate lithium power cell (a NASA developed technology), its own bulb and switch with corrosion proof sealed contacts. NERAC has also assisted Rayovac in developing other products.
