Dimming question on hlg drivers

I have several fissioning fixtures with powered by hlg 240h-54a drivers. By adjusting the Io file on the driver I can dim them to around 94-100w. Each of my four fixtures has a different bottom to which they can be adjusted. I’d like to dim them down further, can I adjust the Vo screw to achieve this? I have other hlg drivers but none have the Vo screw adjust on them. I don’t want to damage anything before asking.

thanks for any info!

No. not in my opinion. I "think" it will work but it may damage your lights a lot quicker then normal use. you can lower it a hair or two but if you go lower then the lights minimum rating then it wont fire up or it might damgae it early.....lets see what the geeks say....

Was just curious as I have a diy 550 clone that is able to dim down much further. I have temp issues (too cold) and I can veg much better at around 80w than at 100 or so. It’s taken a couple of years to believe that you can veg a 4x4 with so little wattage. Still trips me out.
