O.K., let me break it down for you:

The average color of light produced by a light source is measured in the "Kelvin" temperature scale. Lights
with lower "Kelvin" numbers have a distinctly yellowish cast to them; lights
with higher numbers cast a light that has a blueish hue. A the yellow light produced by a candle flame measures about 1900K, while the slightly blue light that comes from a "cool white" fluorescent tube measures around 4200K. Standard incandescent light bulbs give off 3000K light.
So what this blurb is telling you is these LEDs pump out light that's half-way between what you'd expect from a regular light bulb and a cool-white fluorescent fixture. It's a good general-purpose light color.
> . . . 120 lumens . . .
About the same amount of light as a 10-watt halogen reading light.
If you liked the description of the old LED lights
, this sounds like an even (or even slightly better) swap.
