You're absolutely right that it could be the fixture, as I haven't tried it without Insteon hardware. My thoughts were leading me in the direction that I'll have to spend some time with the hardware troubleshooting next. However, that's more difficult than trying settings in software, so before I pull the fixture out of the ceiling and try out different rewiring options I wanted to try posting here to get additional input. Sharing more about the situation, I'm not familiar with commercial lighting fixtures and pros/cons and what brands are good/bad. With the residential fixtures in my home that have sockets for replaceable lamps, I've got a good perspective on what brand bulbs work well for the areas where I use Insteon dimmers. I picked up this LED troffer as it was aesthetically pleasing for the application I needed - filling a big hole in the area above/outside my front door where previous owner placed a 48" fluorescent fixture with a drooping plastic lens tacked up over the cutout (big eyesore). Anyway, the hardware store had this nice looking troffer fixture, it checked the mark of having the ability to dim (0-10V), LED works well in the cold and I knew Insteon had ballast dimmer supporting that. Here's a link to the manufacturer of the fixture - https://lithonia.acuitybrands.com/products/detail/229368/lithonia-lighting/vtl/vt-series-led-troffer to give some perspective. I fully understand that I may need to replace the fixture to solve the issue. If anyone has had success with similar troffer fixtures that don't flicker/flash when turning off from 40% brightness, I'm open to suggestions. As part of the renovation for this fixture - I now have a standard 2x4 cutout with a nice metal trim in the ceiling so swapping to another manufacturer's fixture would be possible. I also observed that the LED section behind the fixture lens is a Samsung PCB strip that's attached to the metal frame. So another possibility could be to gut the fixture of its LED PCB/driver and replace with something else that's more friendly with the Insteon hardware. Presently, I don't know what that LED hardware would be, so any suggestions on those lines would also be appreciated. Thank you for the suggestion and hope the above additional background helps.

Hi All, I have a mildly annoying issue and looking for input/advice on how to solve. Appreciate any input on what to try to resolve the issue. The setup - I have an LED troffer light fixture that's dimmable via a 10V control interface. I have the troffer wired to an Insteon Ballast Dimmer 2475DA2 Ballast Dimmer's Relay controls 120V to troffer Ballast Dimmer's 10V wired to the Troffer's 10V interface The 2475DA2 ballast dimmer is a responder to a scene. The scene is controlled by - a 2477S switch (this switch is capped and doesn't control a connected load) one of the scene buttons on a 2334-2 keypadlinc 8 button dimmer (The keypad's built in dimmer is wired to control a separate load/fixture and this load isn't tied to the ballast dimmer's scene) The LED troffer is very bright when at 100%. The troffer is in a small area, so I only need 40% brightness max. Therefore, I have the scene setup to turn the troffer on to 40%. The Issue- When I turn the scene off, the troffer responds but takes a few tenths of a second where it flickers and then emits a brighter flash before going completely off. I'd like to find a solution that can turn the troffer off (from 40% to zero light output) without the momentary flickering and flash that currently is occurring. I have the ramp rate set to 0.1 seconds on the scene/devices (this appears to be the lowest value that can be configured). I've tried tweaking some settings and observed the following - If I setup the scene for 100% brightness, turn on the scene, then turn off the scene - the troffer will turn off quickly without any noticeable/objectionable flickering or flashing. I would be happy if I could get this same behavior to occur when turning off the scene when it's set to 40% brightness. I've tried experimenting with the 2475DA2's options for the 0-10V settings in the device group settings (for example, turning Group 1 'On Level Volts' to lower values like 3.62) but that didn't seem to have any effect on the troffer's brightness when the scene was set to 100% instead of 40%. I question whether there could be any settings I'm missing to resolve my issue or possible different configuration I could try in my ISY? Or does this sound like a problem that will need to be tackled via a hardware solution like rewiring to control the fixture differently or a completely new light fixture?
