Up to now, the luminous efficiency of a lamp depended on its size and weight. However, our small LED LENSER® P2 definitely does away with the prejudice that big is bright. With a mere 38 g, it weighs less than the end cap of big electric torches. Our Tom Thumb has an astounding luminosity and is equipped with the Blue Moon Focus System. The blue circle surrounding its pure white light cone is simply fascinating. For the P2 - as for all of our flashlights - we have spared neither trouble nor expense. The only thing we saved on is weight.
