Like tenbear, I replaced my 921's with 36-1210 LED panels from 2011_led on Ebay.
I ordered different warm white and bright white panels before deciding on the ones I have. The 36-5050 bright white panel went into the outside hitch light and the 36-1210 bright white went into the range hood. The lights over the bed are 24-1210 warm white panels, DW thought the 36-1210's were too bright.
If you can find them try a 4000K panel, it looks like more of a pure white color vs the yellowish tint of a warm white or blue tint of a cool white.
