Have Already Answered them both.
"... What lumen chart are You using to measure intensity? ..."You already know this.
For the people switching from Incandescent light bulbs to LED's, who need a simple formula.
Lumens or LM (the amount of light emitted from the bulb)
Many Poor Quality LED's will say, 'Equivalent to a 60 Watt bulb'. then say 780LM or 800LM. Where, generally 820 LM is a sort of standard.
What makes it so hard is LM's are a measure of light output. and Watts are a measurement of Power used.
LED bulbs when stating their LM's, also, (sometimes) state the Watts to get that LM.
A 800 LM Bulb, using 10-12 Watts is good, Some are made to use as low as 8 Watts, some are still around that use 19 Watts. 800-820 LM, is close to the average 60 Watt Bulb.
(Which used to be marked, in three ranges)
The forgotten and not well known is Kelvin degrees.
AKA 'K'. That is the color of the light.
GENERALLY
2000-2500 = Candlelight. (Orange/Yellow)
2600 - 2800 = Warm White. (yellowish)
2900 -3100 = Soft White. (White very little yellow
3200 - 3600 = Natural White. (White)
3700 - 4000 = Bright White. (Very 'White')
4100 - 4500 = Very Bright White (Sightly Blue)
4600 - 5000 = Bright Sunlight (More Blueish)
Here is from a chart for, 'about's'.
Less than 2000K: gives off a dim glow of light, similar to what you might find from candlelight; best for low-light areas where ambient illumination is welcomed.
2000K-3000K: gives off a soft white glow, often yellow in appearance; best for living rooms, dining rooms, bedrooms and outdoor spaces.
3100K-4500K: gives off a bright amount of white light; best for kitchens, offices, work spaces and vanities where task lighting is needed.
4600K-6500K: gives off a bright amount of blue-white light, similar to that of daylight; best for display areas and work environments where very bright illumination is needed.
6500K and up: gives off a bright bluish hue of light, often found in commercial locations; best for task lighting.
