Hey how are you doing man, nice to see you back. :partying_face:
Yeah I know what you mean. You need to have the right environment to benefit such output. Dense forest with super tall trees in a ~10 to 20 meter range will make the light shine. In an open environment you will be blinded by the spill in front of you while a large part of the lumens will be tossed in air making it useless.

Yes, true, correct, succinct and well said. I agree that most of the light is tossed away from where it can be of use, and the close in glare makes viewing anything impossible. I have several legacy lesser flooders that do this not quite on such a grand scale. I do not need the current offering that does this in the biggest way.

Great output for 300 dollar! And I like the size, the design and the colour led option. In the picture in post #2 I do not see a 233A though, must be a picture of a prototype.
Thank you for the updated News seery! I see now, that this will run at 4000lm, for 1.5 hours. That is tough to beat in this industry, and becoming standard operating procedure for Acebeam. :sunglasses: :+1:
This looks like something someone at BLF would custom build for fun, not something I’d expect to see commercially-produced. 25k lumens, only 1.1 cd / lm, and only one minute at a time on the highest mode. It’s like a flash bulb — very very bright in a wide area for a short time. For comparison, the Meteor is often considered pretty floody… and it gets 4.5 cd / lm. Its beam is four times as focused as the X80.
Would probably be pretty useful for photography, but I’m not sure when else I’d need so many lumens at such a short distance.
It’s not exactly a light bulb either though… those are more like 0.1 cd / lm, or maybe 0.2-0.3 cd / lm when used in a directional lamp.
At the other end of the spectrum, there’s the BLF GT. It only emits 10% as many lumens, but the beam is 46 times as intense with ~500 cd / lm. Useless for up-close tasks but great for seeing things far away.
To add to the cd/lm discussion: lm/cd (the reciprocal of cd/lm) is an approximate measure of the beam area (solid angle), and so the square root of the lm/cd ratio is a measure of the angular beam width.
