I have 12 hyper violet led on the 38w inventronic recommended on the website but my leds are blinking. It was working for a while and now it just blink like disco light. I check all the led individually and it all works. Can you tell me what is wrong? Any suggestions? thanks.

Pulsing usually means that there is not enough forward voltage connected to the driver. Are they dimmed any? What are the specs on the 38w driver you're using? Are you running them in parallel or all in series?
