I recently purchased the Hampton Bay cobram ceiling fan but find the led light too dim for a kitchen. Are there replacement light kits that are brighter than 46 lumens?

Are you sure of the lumen output? The number you quote is about equal to a 4 watt lightbulb. 40 watt equals about 450 lumens. If you are not happy, return the fan. I have never seen a 46 lumens fan light. Product info states 822 lumens.
