Need help with Compact Fluorescent
California Home

Our vanity bathroom has a 26W Nutone Compact Fluorescent 2 pin
light / with fan - ceiling light.
( the light appears to be about 9 inches long)

It is so dark with this light in the bathroom. I am desperately
trying to get a brighter light...I searched all over the internet.
Went to Home Depot etc. No luck.
Not sure why they do not make brighter lights for 2 pin Compact
Fluorescents.

Any suggestions..where I can a brighter 2 pin Compact Fluorescent
light.

FYI....I am not handy.

Any help would be highly appreciated.

Thanks
Anna

First you need to educate yourself on fluorescent lights, if you replace
just the tube part, then you have to keep the wattage the same as the
ballast, otherwise you risk damaging the ballast and/or the tube

It is entirely possible that you have the wrong tube in there already, a
26 watt CFL in a 13 watt fixture will look dim because the ballast is
*underpowering* the tube.

You will want to get the numbers off of the ballast to know what the
exact wattage of light that should go in the fixture.

A 13 watt CFL has approximately the same output as a 60 watt
incandescent, and a 26 watt CFL has the about the output of about a 100
watt incandescent lamp. If you aren't getting "100 watts" of light,
then the 26 watt CFL is the wrong type for the fixture.

I never puttered around with CFLs and base sockets to see what combos
"almost work". I am under the belief that if the lamp fits the socket,
it WILL work, assuming the mfg used the right ballast with the socket.
Are there any "false fit" combinations that will allow a CFL lamp to
plug into a socket, light up, but not put out full lumens? It's too bad
that the CFL socket designations had to be so obtuse, and the lamps
themselves so singularly mated to a socket type.

This is going to depend on the ballast type and in some
cases the mains voltage. In UK (240V), all the PL lamps
are interchangable on a series ballast because they run
at the same tube current, and the tube voltage drop is
small compared with the ballast voltage drop so the
different tube lengths (voltage drops) have too small
an effect on the tube current to worry about. However,
on a 120V mains supply, that may well not be the case
as there's significantly less voltage headroom. So
although they were designed in Europe with the same
bases because they would be electrically interchangable,
that may not work well in the US. I believe the same
design applies to the 2D lamps -- although there are a
few different bases used, there are many more different
power ratings and the lamps with the same bases were
supposed to be interchangable on 220-240V supplies.

Please post the model number of the Nutone fan unit.

I'm looking at the spec sheet for another Nutone bath fan
and see an interesting typo. The instructions state:

"Insert lamp (26 watt compact fluorescent - NEMA Type
CFTR42W/GX24Q) into the socket."

The problem is that the CFTR42WGX24Q is a 42-watt lamp, nit
26 watts. However, its also a 4-pin lamp and you have a
2-pin lamp, so this is not the lamp you need in your
fixture.

I would encourage you to find the model number of the product you have, then
go to the Nutone website and make SURE you actually have the correct lamp
installed in the product.

If it proves that you do, then I would suggest purchasing a replacement lamp
as my second suspicion is that your lamp is failing.

The type of fluorescent lamp this product uses is NOT THE SAME as the screw
in replacements you commonly use in a fixture, such as those that come
complete with a ballast built into the base of the lamp. In this case, your
Nutone product has a separate ballast built within the housing of the
fixture, and the bulb is just that - a bulb, without a ballast. The concept
is that you get a more robust quality ballast that will last through MANY
relampings, and this saves you money as you don't have to purchase a
complete lamp with an internal ballast each time.

However, it is important that you use the CORRECT LAMP - otherwise it will
not operate at peak levels, and ultimately could ruin your ballast which
will be a more difficult item to replace.

A 26W lamp should provide lighting that is slightly more than a comparable
100 watt incandescent.

If this does not seem to be the case, then you have one of the following
issues:

1. Wrong lamp installed.
2. Correct lamp, but it is failing.
3. Correct lamp, but ballast is failing. (Highly unlikely, usually when
ballast fails it simply quits working or gets very noisy)

Hope that helps.

I think that is optimistic - achieved when either the CFL is a good one,
in newer condition, and at optimum temperature. Or if the incandescent is
subpar (or has light output compromised for longer life).

The highest lumen claim I have seen so far for a major brand 26 watt CFL
is 1800, for 26 watt quadtube and Philips PL-T.

Their design lumens are 1510 (Philips PL-C) and 1530 respectively.

100 watt 120V A19 750 hour soft white achieves 1670-1710 lumens, and the
standard frost and clear versions achieve 1710-1750 lumens.

I have seen some people "turned off" by CFLs failing to meet advertised
claims, whether generally or in specific applications. So I would be
hesitant to claim that 26 watt CFLs outperform 100 watt incandescents,
unless it is known that the incandescents have less output than 120V 100W
"standard" A19 ones.

You're right - this is a classic case of me 'as a salesmen' and you as the
"tech" who really knows what's accurate. In my industry, we tend to use a
multiplier of 4 to 5X the CFL wattage to make claims of equivalency, and in
fact on several major brands sleeve they list similar (albeit misleading)
info.

Given he refers to himself "as a salesmen", then I might speculate that his
"industry" is some kind fo retailing. It could be worse; he might be a
"door to door CFL salesman".
