haha! it's neither of those. it is a self-ballasted compact fluorescent light. it's big! you can't miss it.

2700K refers to the color temperature. this light will give you that warm glow that we are used to seeing in the home. i had to order the 5100K bulbs online from HD supply. the latter bulb will give you more of the daylight look.

photosynthesis uses the orange and blue spectrum. hence, the two lights. however, the phosphor in the bulbs emit over a broad range. that means that the 2700K bulb has some blue spectrum and the 5100K has some orange spectrum. that being said, 2700K emits best on the orange end and 5100K on the blue end.

check out this link. http://www.gelighting.com/na/business_lighting/education_res... it is a comparison of the tri-phosphor colors for 2700K and 5000K compact fluorescent bulbs. mind you that these are spectra for GE bulbs. i am banking on the fact that the TCP bulbs are similar.
