Light Output from LED "bulbs"

[Rich Kallenberger]

I came across a few bits of information which may help members evaluate LED replacement lamps.

Since most LED replacement lamps are rated in lumens (a measure of light output) comparison to watts is best left to the engineers.  A more useful comparison for us mortals is:

#194 bulb (common in marker lights and instrument panels) has an output of approximately 24 lumens.  Therefore to find an LED replacement of comparable brightness you should look for one with about 24 lumens at 12 volts.  Likewise, an #1156 bulb (single filament tail light lamp or I presume one filament of a #1157 stop & tail) is rated at 400 lumens.

I know that there are many other parameters such as beam angle, actual socket voltage etc. but I hope this will provide a frame of reference.
