It will definitely allows you. I did disable the temperature controls on my GT, GT90 and GT4. Will do my GT94 as well later today. The courier will drop it off in the next two hours.
at 1km you will not be able to tell much as it is hard for most human eyes to even see that far clearly.
Although my statement above was a more general opinion I hold, there are exceptions to it of course but in general I pick the OP reflector when available.
In this lights case the SMO reflector has a slight donut hole (simply due to how large the die is on the LED, not much you can do about it). I am guessing the OP reflector would basically eliminate this which would be nice for everything except max range usage IMHO.
I read in some reviews that the GT94 gets hot very soon. Perhaps the step down set by the factory is to prevent the driver from getting damaged. Buck drivers are delicate. Perhaps it is better to leave the factory settings which has some good reason.
I haven’t seen a donut hole in the videos posted on Youtube. Perhaps it is very light and can only be noticed by projecting the beam onto a white wall at very short distance.
I set the default step-down temperature at 55c in the firmware. Due to variances in the MCU’s this can vary by 15c+ from light to light. So the step-down could happen between 40c and 70c depending on your particular light. This is not a problem since the user can recalibrate the temperature to their liking.
The factory did not change the temperature setting from what I set it to, it is just simply variances in the MCU’s. It is perfectly safe to raise the tempreture or even disable it. The internal components are rated for 105c+, the cells are the only thing you really have to worry about, VTC6’s are rated for 80c but lower quality cells can be rated for less.
In my stress testing with thermal control disabled I saw a max temp or ~95c at the head and the cells were ~75c. So still safe even with thermal control disabled, although it is not recommended to do that on a regular basis.
In a nut shell, you are welcome to re-calibrate the temperature control to whatever temp you want or disable it completely. It is easy to do in the firmware, I simply don’t have it memorized. It should say in the manual how to do it though. If not there is a cheatsheet in the GT70 thread that has it for sure.
Correct, it is the same driver setup as the GT70, a resistor bank for the low modes and FET for the higher modes. The GT4/GT94 driver is just beefed up a fair amount to handle the ~30A it has to deal with.
I doubt a camera would pick it up easily, it is faint but there. I mostly noticed it when getting lux readings, the numbers were higher at the edge of the hotspot then in the center. It is most noticeable at mid ranges.
I am a technical guy though so I focus on things like that more then most. On the flip side I don’t generally care much about cosmetics and that sort of thing.
Cool! Thank you sir. Another question. If and when I get the reflector could I send you the head and you install the new reflector? I would be willing to pay a fee. I don’t have the tools and am not comfortable disassemblying the light. We can take this to pm if you like.
Kind of/sort related/unrelated, TA - were you involved in the HK90 design or driver? I got one coming in a few days. The price of the GT94 is out of my reach for now, so settled on a "Super Shocker", paying homage to the BTU Shocker of a few years back - the HK90 is a triple LED at 100 mm head diameter size, SMO reflector, 3 21700's, 3 SBT90.2's. Neal gave me a pretty good deal.
