The Pulsar Light by Princeton Tec is a great light weight solution. This Princeton Tec Headlamp is slightly larger than a quarter and weighing 7 grams, the Pulsar provides instant illumination for any situation and offers easy battery replacement. This compact Ultrabright Princeton Tec LED burns with unbelievable intensity making it the perfect choice for key chains, backpacks, book bags, zippers and emergency situations.I am a fan of all Princeton Tec Headlamps.
