AceBeam X75 Micro-arc Oxidation Powerful Flashlight |AceBeam

The flashlights from AceBeam are real leaders when it comes to beam range and lumen. AceBeam introduces us to the extreme possibilities that LED flashlights offer us today. I have searched international forums and I have seen tons of comparative beamshots of BLF GT versus K75, posted by known posters, and I can concretely say that the K75 yields surprisingly more performance than the BLF GT.You’ll note something about this chart – and I noticed it in use, too. In the manual, the lower two modes for each group match 7 lumens, and 150 lumens. In practice (on the lux tube and current meter both), ECO and POWER Low mode is clearly different. The manual’s just a little wrong and that’s fine – I’d rather it be this way really. Why duplicate these modes, and in practice, they aren’t duplicated. Pulse Width Modulation

Eco mode is great for extended runtime. But I guess people would like to use the highest setting most of the time. ECO, K75 трябва да бъде оборудван с 4 x 18650 батерии с висок ток на разреждане, които могат да отдават поне 10 ампера ток. I took all of my readings from fully charged Acebeam batteries. I tested Amps with a Fluke 77III and standard probes and Turbo with short copper wires to eliminate losses over the wire. Amp measurement The problem with doing this is the difference in the opening of the Integrating Sphere. The Convoy S2+ shows different numbers depending on the size of the opening in the Sphere. The K75 uses a much larger opening. So I used the same opening to measure both lights.The distance from the tower is about 650 meters. Shot with a 100mm lens, 1600 ISO, f4, 0.5 sec, 5000K

Acebeam K75 review | Extreme long-range flashlight - 1Lumen

In the lowest settings, the beam looks a little greenish. And for the beam shots, we will take this bad boy outside, so we’ll see how it looks outdoors. All output numbers are relative to my home-made Integrating Sphere and was set up with an Extech HD450 Lux Meter for measurements. For bright flashlights (above 5000 lumens) I am adding a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that is tested at 137 lumens.

One more power-related feature is the power indicator, somewhat beside the switch. When the light is on, this indicator is on. The battery tube has a great amount of knurling so it isn’tslippery at all. Another great characteristic! The tail cap, in the shape of a "U" has a knurling similar to that present on the body, in the lower part we find the writings of the brand, model, certifications and serial number. It is possible to insert, in the two slots that it has, a cord or a carabiner of a shoulder strap.

I should point out that the values expressed by the graphs must be taken, above all, as a reference because they are made with means and environmental conditions different from those used in the laboratory. The included lanyard attaches through either of these two holes on the tailcap. If you run the light with the handle, you could also attach the lanyard there, too. The user interface (UI) of the Acebeam K75 is simple and reflects the one already seen on other torches in the same house. It is managed by just one switch placed on the side. We have 6 levels plus the Strobe available. There’s a massive stepdown to over 2000 lumens on the highest Turbo (POWER Turbo). Kind of expected – this mode creates a lot of heat, and that has to be managed.Size comparison with other flashlight throwers. From left to right: Acebeam K75 (Luminus SBT-90 II), Astrolux MF04S (Cree XHP70.2) and Lumintop BLF GT (Cree XHP35 Hi). The emitter here is quite unusual. It’s a very made-for-throw emitter. This is the Luminus SBT-90 Gen2. This emitter boasts an emitting area of 9mm The non-slip knurling on the body of the K75 is rhomboid in shape. Good quality of the writing as good is the quality of the well-lubricated threads.
