Not a stupid question at all! I don't know if you cranked your light up a little bit yet or not but if you're unsure you could spread it out over a couple weeks until you're up over 50%, somewhere. But if you do it gradual you'll be able to notice if it's stressing your plant out or not and if it is you're right there to readjust before it gets out of hand. Just watch the plants is all watch those leaves you'll know when you've gone too much too quick.
