Hi Don,

GE's 29-watt spiral is said to produce 2,250 lumens.

Sylvania's 135-watt 150A/135/SS has a rated output of 2,050 lumens
and, at the higher end, their 135-watt 150A21/135/SS produces 2,450
lumens. That would put this CFL more or less smack-dab-in-the-middle
of a 135-watt incandescent.

Sylvania's 150-watt A21/A23 incandescents range anywhere from 2,090
lumens at the low end (inside frost, rough service, 1,000 hour life)
to a high of 2,810 lumens (inside front, 750 hours). Their Standard
Frost Excel (2,500 hour life) produces 2,225 lumens.

Perhaps its closest match is the 150-watt 150A21/W/RP Soft White (750
hours) at 2,640 lumens, in which case it comes up a bit shy of the
mark (by about 390 lumens).

So although its true output is closer to a 135-watt incandescent, if
you were to replace a regular 150-watt soft white bulb with this CFL,
I doubt most people would notice any appreciable drop in light output.

Cheers,
Paul

GE makes this claim with their T2 line and it holds true, well, at
least in part. Their 10-watt spiral (40-watt equivalent) is just 3.7
inches long and their 13-watt spiral (60-watt equivalent) is 3.9
inches. By comparison, a standard 40-watt or 60-watt A19 incandescent
bulb is approximately 4.4 inches in length (4 and 7/16 inches to be
precise).

As we move up in wattage, things start to unravel somewhat. Their
20-watt and 23-watt spirals (90 and 100-watt equivalent) are 4.8 and
5.1 inches long respectively. Their largest mini spiral (29-watts/
150-watt equivalent) is 6 inches long,

How many lumens does this 29 watt CF produce? So far, the brightest I
have ever seen a 30 watt CF being is only slightly brighter than a 1710
lumen 100 watt incandescent. A 150 watt 120V "standard" incandescent
produces 2880 lumens last time I checked.
