Exact model number?
Also, just as a general comment, you should not use a dimming switch with non-dimmable bulbs even if you only intend to use it as an on/off switch unless that particular model has a parameter which lets it be set to operate as on/off.
The physics are just different for dimming switches and 100% bright is often not the same as just on. This is particularly an issue for LEDs and fluorescents.
