I bought this, dazzled by the 11,000 announced lumen. I had already bought the other product: 3 800lm Lumens Torch TrustFire 3T6 CREE XML XM-L T6 LED 18650. I realize that this new lamp, visual feeling, does nothing more than another. Knowing that the product is delivered without battery or charger (different from the other), it must be ordered in addition, devilishly expensive stuff. I do not recommend this loupiotte and recommended warmly that at 3800 lumens
