30Q’s will be more than enough, but 35E seem to be the recommended cell for longer run time. This light doesn’t need the high amp supply as the light is only drawing 2.5A.
Wait for a night when we have a 2000-3000 foot ceiling, and shine it due east. I should be able to see it from Ashland. Better yet, when mine shows up, we’ll have to try and converge them over Iron River. They’ll think the world is coming to an end.
So is the shipping version of this light warm or cool white and what is the candela roughly because I knew it changed through the build process as far as I know
Ok, here are the results of my testing with the Dr Meter LX1330B lux meter and the XHP70.2 GT.
These readings are at 10m, outside.
First the stock GT for a reference point.
- 1.1 Mcd for a total of 2100m of throw
Next up is the XHP70.2 80cri GT with dome on
- 560 Kcd for a total of 1500m of throw with over 9,000 lumens!
Lastly the XHP70.2 80cri GT with sliced dome
- 750 Kcd for a total of 1725m of throw with over 9,000 lumens!
So needless to say I am pretty happy with the results. A P2 bin XHP70.2 could most likely get a bit more then this but I didn’t have any on hand when I put these together.
Here are some very crude beam shots that kind of show the difference.
Dome on > Dome sliced > Stock GT
Stock GT:
XHP70.2 sliced Dome GT
XHP70.2 dome on GT
I am officially listing both of these lights for sale and I can swap the LED to something else if someone wanted.
I will post a thread for them later when I have some time. PM me if interested. They will not be cheap sadly, this is one of the only ways I am making money off this project and I need the money.
I could only get 4 of these prototype mcpcb’s so I can’t make anymore of these unless they put it into production down the line. Which they are still not giving me a straight answer, hopefully these results will bring them around.
Yeah, I am having a real hard time deciding which one I like better myself, every time I think I have decided I try the other one and I realized I have not decided lol.
