The panel needs full AC line voltage all the time when On. Then a 0-10DC dimming control voltage on its control connection.
Yours does have a 0-10VDC dimmer voltage input? In my search for the LED light. It was not clear the light has the input standard or needed a separate driver with the 0-10DV input.
Are you using the 2477D to try and dim it with its AC input. That will not work.
You need a 0-10VDC control signal. The Insteon 2475DA2 0-10VDC dimmer is is what you would need. It has a relay output to turn On and Off the power to the fixture and a 0-10VDC dimmer control voltage. There is a manual link on the page if you want to see if it would be suitable for your needs.
You are welcome. It gets wired directly to the light and supplied power all the time to its AC input. Then you can wire its On Off relay output to the lights AC input and the 0-10VDC to its control input.
You could even still use the 2477D. With Line and Neutral connected, Load capped off. Then linked to the 2475da2 to control it.
