How do I know or can compare the amount of light produced and the amount of energy the LED or bulb uses?
This is the bulb I was looking at.
To compare brightness you need the Lumens rating in the 200 to 350 range or about 2 to 3 watts. The bulbs listed are going to be less light. Also they are listed as having color of White so probably a little on the glarish side and possibly a bit blue tint. Probably want a Warm White to compare to incandescent.
Here is a 2w bulb to compare:
