Mines wasn't adjusted to full power, I checked the driver turn screws on the back of the hlg drivers and they can be turned up or down, IV since learned that the same light comes with an adjustable nob as part of the light, I never got this part when I bought mine back in February, seemingly you get the adjuster if you buy one now though, it's pissed me off that I don't have this part and I'm wondering if I can get a hold of this part and add it to my sf4000, anyone know if this is possible?
