Refresh my memory on how this works? I had 3.5% lamps in my stand up and when I metered them right outta the box they metered 46.3ish ...I just tried a 6.5 lamp in the same unit outta the box and they only meter 26.1 ish. Logic would dictate that these are half as strong. Is this logic faulty? Please be kinda when explaining this to me. Thank you!
