Every reflector with look like that with just the right lighting. My reflectors look excellent but if you get the light angle just right they will look like that also. Your reflector is just fine.
Your’e exactly right mine looks really smooth looking at it but i you get the light just right you can see some lines. I measured 1.2 mcd at 15 meters so it doesn’t really matter the thing is a monster thrower.
It can't hurt. The biggest reason I wanted one was just to keep dirt and dust off it but I have been thinking about something similar to give added protection. If you use any kind of wood I would recommend painting or sealing it to get rid of the dust from it.
Post #5 has a new completed list of all the sign up requests.
You are shown as requests #1215, #1216 and #1762.
This list is not showing whether or not you want batteries, though. Anyone wanting a set of 8 batteries can easily add them to their shopping cart at the same time as they order their GT.
For those curious about the best way to remove the switch cover, a pair of snap ring pliers is your best friend. I have a set with multiple tips that can apply force in both directions. This style of plier (the blue one) can both squeeze together or squeeze apart.
It a 19mm diameter cob style led. $379 without the heatsink. It has a 35 to 39 volt input and does about 450 watts.
It would not be suitable for any type of thrower as the hotspot would be huge. You would probably get 500 to 600 meters from it in the GT (my rough guess).
This is a standard Narsil feature, but it should have been in the manual anyway. Just added this to the FAQ in the support thread:
The GT has low voltage warning and shut-off. At what battery voltages does this happen?
At 12.0 V (3.0 V per cell) the GT will blink the main LED and step down in power. It will do this repeatedly until the battery voltage recovers above 12 V.
At 11.2 V (2.8 V per cell) the GT will blink rapidly and shut down the main LED.
Note that these voltages can be ~0.05 V per cell off in either direction, depending on the component tolerances and temperature. These voltages are monitored under load and cells will read higher when removed and measured outside the light.
These numbers are from the NarsilM 1.2 source code, but I did also confirm them using a power supply on a production light.
