With Sanyo 2600 cells, it is 1.66A for Crelant 7G5 and 1.40A for Sunwayman T40CS.
The crelant's driver and emitter portion gets hot pretty fast.
BTW, this light can do candle mode!
And my Solarforce Masterpiece Pro-1 scores 600 lux with 2 freshly charged 18350 IMRs. So it is lower throwing and it looks to be so in my house. However, aiming at longer range targets at 100m-400m, the Solarforce is brighter than the STL-V6. I guess it's a matter of focus.
I noticed that too. I think copper MCPCB and good thermal compound would warm up this part even quicker. Lots of juice is beeing converted to heat.
Yes, it can. I knew about it since seeing the photos on shenzen-wholesale. This is exactly the same desing as Catapult.
I think it's more a matter of measurements accuracy and mathematic assumptions. When taking measurements at some distance and calculating it back to 1m values, you're making an assumption that at "zero" distance (lets say the opening of reflector), the beam is focused to a mathematical point. This assumption leads to getting certain angle of beam. In reality, at "zero" distance, the beam is not focused to a point - it has already a width of reflector opening, so real angle of the beam is smaller (by a small margin, but still). You make calculations using this "wider angle" approach, which leads you to lower values than in real life. Increasing the measurements distance, decreases the error factor, because of mathematical distance to real distance ratio is closing to ~1. That's why, increasing the measurements distance, increases also the results. This is most important, when measuring throwers, where the beam angles are very small. An assumption that beam angle apex is on the reflector opening, creates an error factor. In reality, this apex, is behind the flashlight. So the farther away from flashlight you make your measurements, the lower is the error factor and more accurate and real-life result you'll get :).
The "results increse" issue niggled me lately, so I started to think about it from physics/mathematics point of view ...and these are my conclusions.
Of course, there are also other factors, that could mess with results. Like beam convergence for example ...but the conclusion is, the larger measurements distance you choose, the closer to real-life results you'll get. :)
I am looking at both the Solarforce MPP-1 now as well as the Crelant 7G5 at very far objects. Both look really close in intensity.
Not feeling like it to do beamshots though...maybe next time.
Though the design is really minimal and nothing "attractive", the matt surface of the HA is quite nice. It's something different from the Fenix/Sunwayman type. It looks serious.... minimally serious NO-NONSENSE. Don't mess with me type. Not attention calling.
Actually it does output somewhat high figures initially during a ceiling bounce. But it sags quite fast. That's why i put in the cooled-with-ice figures. Quite a bit higher.
As for brightness drop ...probably MCPCB is not the best. I broke the centering ring in my 7G5 and it seems this is the same MCPCB (and LED) as in Balder BD-4. Not the best in my opinion. I guess, a good LED from known source soldered on a pure copper MCPCB would behave much better. Nevertheless, even after brightness stabilization this thing throw farther than Cat V2 @ xm-l and T40CS.
To remove the emitter, you have to remove white plastic cover shown on the photo. Unfortunatelly it's destructable operation, because it easily breaks (mine broke). To remove the circuit, you have to unsolder the LED, and through the holes, punch it out. It's press fitted in some brass pill, so there's little chance, you can remove it from battery tube side.
The reflector dimensions are in the product desctription. From what I remember it's 58Wx55D.
Nice video, however you are lucky this flashlight had reverse polarity protection, otherwsie you could have burn the driver and you would have come to the forum saying that you have received a bad Crelant.
The output will be just a bit higher on 3 CR123A and 4 CR123a it will go up to 910 lumens. Instead of 860lumens with 2 rechargeable Li-ions.
Also received mine today Finally. Really impressed with the build quality of the light. Hotspot is small and tight. The UI isn't all that bad and actually allows for momentary on and it seems to remember the last mode used. Overall I'm very impressed. This is also my first flashlight with this form factor, and I must say that I really like it :)
