All Scubalamp lights use constant current (continuous output) drivers; unlike other brands that use a variable output with 'Big' claims. What this means is that you will achieve full rated brightness until the battery reaches around 30%. Following, the light will dim to preserve the remaining battery life.
A light that does NOT use a constant current output driver will begin to dim almost immediately. It will continue to dim as the battery is depleted and the voltage drops. This means that a light rated at 2000 lumens, will only be around 1500 (or so) within the first few minutes. Buyer beware of large output claims for the rated batteries. This is one of the main reasons why we recommend our lights in addition to the durability and quality.
