FAQ:Can I use dimmable light bulbs without a dimmer?
Can I use dimmable LED bulbs / lamps with just an On/Off switch (without a dimmer) ? Yes - This is a good idea if you are thinking of upgrading to a dimmer in the future. Ensure you buy a LED compatible dimmer. ... Non-dimmable bulbs should NOT be used with a dimmer.
