Hellz yeah ! Let me know what you find out, I'm all about micro tuning. Will look around for the 4K. Any safety issues I should look for? I already know it's bright as fuck! Welding goggles seem to do the trick. My left arm felt a little crisper though, read somewhere about long sleeves...I have the ballast at 50% for now, max distance available is 18", what do you recommend? And thanks for the after hours help man!
