[quote=Anonymous]1) Light produced

If you have a package of the old GE light bulbs, look for the number of “Lumens”.  This likely will be in smaller print.  This is how much light your old bulbs produced.

Trying to clarify:
Watts is how much electricity the light bulbs consume.  Lumens is how much actual light is produced.

When buying a new bulb, look for the Lumen rating, not the “equivalent Watts”.  Get new bulbs with at least as many Lumens as your old bulb.  There are no rules on how many Lumens a “60 watt equivalent” bulb needs to have.  So light bulbs often are misleadingly labeled. Lear to hunt for Lumens when comparing bulbs.

2) Light color

A more yellowish light will have a lower “color temperature” than a more white light.  Color Temperature are measure in “degrees Kelvin”, usually written as “K”.  Light that is very white usually will be 5000K or higher.  Classic “cool white” light color is somewhat yellowish and will be somewhere in the 2700K to 3000K range.

“GE Reveal” is a bit of a special light bulb.  Although it is around 3000K, its light spectrum is modified with special glass so that things it lights up are not as yellowish as usually would be the case for that color temperature.

3) Light bulb design

Some light bulbs have more glass area and so emit light in more directions - up / down / sideways.  Other LED bulbs have a big solid white plastic sleeve covering the bottom portion of the glassy area of the bulb.  In practice, these bulbs with the plastic sleeve do not emit as much light as the kind with maximum glass, simply because the solid white plastic blocks some of the light.

I apologize for length, but hope this was reasonably clear.[/quote]
