Hello backanna. Thank you for your message. Have you been able to check whether you have switched on the dimmer? All you need to do is press the dimmer button a few times (1x dimmed; 2x completely off; 3x completely on). You are also welcome to contact us directly by email at service@stadlerform.com or by phone on 041 720 48 48 so that we can look at this together. Best regards, your Stadler Form Team
