MCD is short for millicandela But the convertion to other ligthing unit is not simple There is no definitive answer. A millicandela rating is determined by an on-axis measurement of peak intensity at a specific current, not by measuring total light output. Since the light emitted by a diffused LED is spread over a wide viewing angle, the on-axis value may actually be less than a non-diffused LED from which all light output is concentrated in a narrow beam. Thus the total light output of a 20 mcd LED may be greater than that of a 100 mcd LED though the on-axis reading is less.

What is a difference in the brightness of two lights indicative of?
It is indicative of their relative brightness, measured in candelas (units of brightness, also called candle power).
What word is the description of the brightness of light?

1996 Cavalier Chevrolet no Hi beam light and no DRL lights?
Hi beam lights only the High brightness filament of the headlight.Lo beam lights only the Low brightness filament of the headlight.DRL lights only the High brightness filament of the headlight, but at reduced current.Do you see the pattern?

You are building a string of lights using several bulbs how is the brightness of the lights related to whether you connect the bulbs in series or in parallel?
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
Why won't the dashboard instrument and center console lights turn on in a 1996 Chevy Cavalier?
You have a blown instrument lights fuse or it is just turned off. There is a rheostat that controls the brightness of the lights. Find it and adjust the brightness.
Can you use regular batteries in solar lights or should they be rechargeable?
Yes you can use regular batteries in solar lights but it won't work on some solar lights like the inwood solar lights but some inwood solar lights can run on regular batteries. But some solar lights can only work on rechargeable batteries and come on at dusk and off at dawn or after six hours.
Sudden increases in brightness of the chromosphere of the sun?
Solar flares.
