A very nice mod, converting the NH from short arc Xenon to using a Chinese HID Conversion kit bulb and Ballast.
Not trying to undermine your conversion effort. However, I can assure you that (shown) ballast in your pics, does not output 70 watts. The Chinese ballasts are know for using input watts to the ballast for their claims as well as often gross exaggeration of the watts on top of that. That ballast should have more large heat sinking fins to handle 70 watts input let alone 70 watts output. For your situation it may be adequate.
My bet that ballast you have shown, the output is in the 50 to 60 watts range. The input watts can easily be verified get simultaneous voltage and current readings from the battery to the ballast. Those number multiplied will give you input watts to the ballast, it is safe to say the most Chinese ballasts are typically about 85% efficient. Taking the initial input watts X .85 should get you an approximate idea of the watts going to the bulb.
I assure you it is not China junk.. Similar to Morimoto.. And its actually just over 70 watts.. Using a 14.8 Volt, 4S 6000mah 50C LiPo. As noted on buddies Circuit Trac pro.. Overkill but cool.. Again this is just a modded NH for myself, not trying to compare lights. just showing that the same or better can be accomplished for those with few duckkets, and a few hours. I guess it can be considered a sleeper. One thing for certain anyone that does use a LiPo battery should use utmost care and implement a tested design. They are amazing if used properly. With a proper charging system.
One thing, looks can be deceiving.. So I find it best not to judge books by there covers. That's why I know the LX70 is a great light with a unappealing cover.. Just kidding.. I will get some night shots up here. Take care....
