have some flashlights (about 12 pieces) and can therefore compare well. Dioe lamp is amazing for the price. The specified lumen (China lumens) are of course not reached. In my opinion, there are about 400-600 (operating with AAAs). So at the moment my best lamp by Lumen / price ratio. The zoom is great too, from total floodlighting up to the strong Thrower! Processing: Lamp in: 4/5, 3/5 Battery cage (for AAAs). Have equal a second order!
