I feel criminal using the K75 in urban environments. Whereas with the T21vn I could point it around discretely without flooding everything around the hotspot, but with the K75 it’s like I’m just barfing out light everywhere in the general area I’m pointing. What a monster.
In these pics I’m pointing at a face of a parking garage 700 meters away. Camera settings were locked at f/2.0, 1/20sec, iso 640 for all 3 shots.

t21vn:
K75:
The T21vn decently lights up the middle part of the face of the parking garage, and barely the tops of the trees just in front of it.
The K75 lights up the entirety of the garage’s face, wraps around it to the right side, lights up the trees in front of it, lights up the trees in front of those trees, and the spill completely lights up the tree that’s about 20 feet in front of me to the left in the foreground.
Could you post more beam shots please? Also, how does the beam stack up against say MF04 or blf gt? Would you say it hits 1.5m cd as advertised? I own a K70 and am seriously considering buying a K75 when it becomes available here.
The dimensions on acebeam’s website seem accurate. Maybe I can take a pic of it next to some popular lights? I guess the most popular ones I have in my collection would be E07, ROT66, CatapultV6, and TN40. I don’t think people like the plunger style lights as much, but I sure do!
I’ma try to hit a local park in the next couple nights to get some beam shots there. There’s a bridge in that overlooks a river valley.
Awesome! Please include the RT90TS in your pic too if you happen to own it as part of the comparison… or any high output thrower like the X65/mini or TN40S. (As far as the impression and adrenaline you feel once you power it up to turbo!)
Thanks for comparing the lights. However I would much rather see a comparison between the Astrolux MF04S, which would be a better light to compare K75 to. The MF04S has an 70.2 and not a 35hi.
If Acebeam wanted to immediately de thrown the Astrolux and BLF GT, they should have made the k75 with active cooling. Just saying.
If I had to guess, dedomed XHP70.2 MF04S would do around 5000-5500 lumens and 900kcd. It should definitely manage a turbo output a little longer than the K75 at its turbo. Stock MF04S with dome on was quoted at 6000 lumens and 600kcd.
If ran direct drive, a dedomed XHP70.2 in the MF04S would do like 8500 lumens and 1.3mcd, and probably get as hot equally as fast as the K75.
I definitely don’t like the idea of a loud, active cooling light. What Acebeam could have done was introduce an output of around 4500-5000 lumens that wouldn’t get hot nearly as quick. The efficiency of the SBT90gen2 is going down the toilet when driven to 6300 lumens. . And as I wrote previously in the topic, I definitely would have moved the cooling fins that are halfway up the head further down to be more usable. When more conservatively driven, it seems pretty great (2500 lumen level has no heat problems and runs with ruler flat regulation for a little over 2 hours.)
