Yellow. I purchased two boxes through Revain because the item has the same packaging and specs (watts, lumens, "daylight") as the box I bought at our local large box hardware store. They arrived in a brown box (no big deal), with the same specs, but in yellow (big disappointment!). The white bulb in this photo is from a local shop, while the one on the left was purchased from a Revain vendor. Yellow and white tone is of great importance in small rooms.
