Why is there a delay in 1 LED downlight turning on/off?

Hi. I have 4 downlights installed: Aurora EN-DLM981X GU10 240v Downlight, Aurora EN-BZ91W Bezel, Aurora Enlite EN-DGU005/30 5watt GU10 LED Lamp which are connected to Varilight LED V-Pro IR Dimmer. The downlights have a push-fit terminal block with loop in/loop out and there are no transformers installed. These LED downlights are new and are an upgrade from halogens. My issue is when I turn the dimmer on/off, there is a delay in only one downlight turning on/off. It is the same one all the time. The other 3 downlights switch on simultaneously. Thanks in advance for your advice.
Are you a tradesperson and able to answer this question?
No idea. It cannot be anything other than a manufacturing issue in the lamp itself or compatibility issue with the dimmer switch. Definitely not anything to do with wiring and certainly not anything to worry about. LEDs are notoriously fussy about being dimmed. Personally I would avoid dimming them altogether and just have a basic on/off switch. Dimmers are more trouble than they are worth.
The v pro dimmer is a soft start device which you can adjust to suit your requirements. This results in a slight delay in the response time of the led lamps. In my experience these are a very good dimmer for led lights. But you need to read the instructions.
Unfortunately, home LEDs are still relatively new and they suffer from this characteristic delay --- which may vary from brand to brand -- and manufacturing variation --- where bulbs from the same manufacturer may vary, even within the same batch. It may be low load on the dimmer, you can get low load capacitors to help with this problem. Normally you would fit the capacitor at the first Led on the circuit. You can get these at any electrical wholesaler. I would probably speak the the manufacturer first.
I believe there may be an issue with the diode and the lamp will shortly blow you will need a replacement GU10, make sure you get a high quality dimmable one.
Thanks

Trailing edge dimmers These more modern dimmers have many benefits over the leading edge type. These improvements include smoother dimming with less buzzing and interference. Trailing edge dimmers have a much lower minimum load than the leading edge, making them far more suitable for powering LEDs.
