Look like 6000k cool light cobs, most of the floodlighting ones or street light ones by us are like that. They have a brighter yellow look of the cob itself then the warm light ones. We just installed 16 of the cob floodlights around the X-ball field we play at, the top light is from one of those floodlights 6k, the bottom from a 3500k version, they look more like construction truck yellow
Fire them up and see!
