I studied the type of LED. The XHP70.2 and XHP70.3 chips (not XHP70) should be the brightest. I haven't seen any product using XHP70.3 with the same brightness as XHP70.2. In the beginning I was looking for high lumens. Some other products are described as 90,000 or 100,000 lumens, which is too good to be true. I then turned to see which LED chip they were using and realized the key was XHP70.2/3. In the brightest mode, the battery discharges much faster. 25% battery consumption is shown in just a few minutes due to the higher power consumption.
