Are these terms familiar words in your everyday vocabulary? Can you toss them off in considering what light bulbs to use in your lighting scheme? I’ll bet not, for most of us.
Margot Austin, senior design editor of Style At Home magazine provides the following definitions that should help straighten out our thinking and provide a useful tool to get the just-right bulb for each fixture and for each use of our lights.
First of all, what do the terms mean and why should we care? Each term is important in choosing the appropriate bulb, since manufacturers packaging can vary greatly in what kind of information they provide.
- wattage: the amount of energy used by a bulb
- lumen: the amount of light emitted by a bulb
- kelvin: the temperature of a colour
- warm light: light with a yellowish cast
- cool light: light with a bluish cast
If you are thinking about buying compact flourescents, you will find they come in a variety of colours to suit your decor. The colour is determined by the kelvin temperature of the bulb; a lower kelvin temperature means the light will be warmer and slightly yellowish, a higher kelvin temperature means the light will be cooler and slightly bluish.
In my next posting I will talk about comparing flourescents and incandescents (the standard light bulbs). In the meantime, take a look at my website to see the many beautiful, smart and up-to-date lighting fixtures that are available at low prices.
