Using a boost circuit, the scientific cooling air duct design provides 20,000 lumens for 30 minutes. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable. The second-highest output (ECO Turbo) is almost perfectly regulated and heat never becomes an issue whatsoever.

ACEBEAM K75 review - Longest LED beam of 2019!!!! 2500m!!! ACEBEAM K75 review - Longest LED beam of 2019!!!! 2500m!!!

The ACEBEAM K75 is brighter and has more throw, the BLF GT has a narrower hot spot in addition to having a warmer color temperature.That is, on any mode, at no point will the light step down and give you reduced output (ie reduced throw).

Manual has this wrong – seems to say it’ll go back to the memorized mode, but it in fact goes to low.
