A better way (than wattage) of assessing brightness is luminosity, measured in lumens. For examplem a standard 40w bulbs delivers about 360 lumens. Nevertheless, luminosity alone just isn't adequate to gauge how vivid a light source basically seems. Beam angle and light "color" may also be vital.

LEDs are intrinsically directional and so have a pretty narrow beam; they've also within the previous tended to be over the neat side of points, which we perceive as bluish. This produces rather a harsh impact with modest places of pretty extreme light in a sea of dark spots. Good high quality LED spotlights will market their beam angle (120 degrees is a lot wide enough and will create a superb, uniform light pool).

There's also the matter of light color, measured in Kelvins. Something under 3000k is classed as "warm white" and values above 4000k are termed "cool white". For many domestic scenarios your must be taking a look at around 2800K to recreate a familiar ambiance.
