I'm shopping for a flourescent lightbulb - what does the 27K plan? I know that 13W is the wattage, but there are two bulbs,...

I know that 13W is the wattage, but there are two bulbs, one is 27K and one is 35K. What does that parsimonious?
Answers:    Refers to the color as measured in Kelvin. The smaller number is redder than the bluer colored 35K
Beware! 27K is the price- lb27,000. Try B&Q, their prices are much cheaper, starting from lb18,200 next to the added extra of low cost finance.
Hope this help,
