Well u know what, i think its 2700 LUMENS, and 3000 Kelvin.
If it dosnt say on the box, its typically a 3000 kelvin bulb. Ive found that out when shopping at local hardware stores and wallmart and gettin random CFLs.
If its something out of the ordinary, like daylight, or warm white, it definitly will say on the box.
All of mine have been that way. If you go through the internet, it starts getting more specific when you buy.... its alot easier.
