If the inverter voltage waveform is independent of load,
I can't imagine adding more lamps making any difference until
the supply voltage changes.

Did you look at the voltage waveform from the inverter?

I'd suggest that you might have cause and effect reversed.
The 100W CFL that I just measured has a power factor of .6
as measured by a kill-a-watt.
But that's not the whole story. Power factor assumes sinewave
current that's out of phase with sinewave voltage. Not sure what
the KAW is measuring or how it decides what math to use to generate
that PF number for non-sinusoidal inputs.

When you drive a CFL with a fast-rise input, you cram much of the
energy
into that edge instead of spreading it over a much longer portion
of a real sine wave. That requires a much higher peak current.
Perhaps multiple lamps exceed the peak current
that the inverter can supply causing a voltage drop and consequent
lower light output.


Maybe the term "interference" patterns would be better. Like when you
use a strobe light on a rotating object and wither the light appears to
go in one direction, the other direction or appears to stand still.

When two dissimilar frequencies "beat". You will have super nodes,
super anti nodes, the frequencies subtract and the frequencies add.

When I was younger I built a Zenith/HeathKit Oscilliscope. I no longer
have it or another other scope to have examined the wave forms.

I understand the concept, but don't think it's relevant.
The typical cheapo modified sinewave, aka square wave with some dead
time, uses an inverter to generate a DC voltage somewhere around the
peak of the desired output voltage. It uses a bridge of FETS or
similar to generate the modified sine wave from that DC voltage.
I'm assuming there are various ways to protect the bridge if the
load is too much.

I bought a B&D inverter at the thrift store yesterday.
Quick look suggests that they use a fixed duty factor
that's independent of load. The only thing that appears
to be regulated is the voltage ahead of the FET bridge that
turns it into a bipolar pulse. The datasheet claims it
has soft start technology, suggesting that it somehow
monitors peak current. Not clear how they use that tho...

If your CFL has a diode bridge followed by a capacitor, the input
current with sinewave drive happens over a relatively small portion
of the input sinewave. Power factor is low. When you drive it with
a fast rise pulse from the inverter, the peak current is much higher.
I = C * dV/dT. For a sinewave, the dV/dT is relatively low near the
peak where the diodes conduct. For square wave input, the dV/dT is
WAY higher, so the current is much higher.

I'm suggesting that the inverter can handle the peak current for
one lamp, but not two.

Should be very easy to verify by looking at the waveform.
I expect there's lots of noise on the waveform, but it's unlikely
that is the cause of a major brightness decrease.


I don't think the CF uses just a simple bridge rectifier with
electrolytic capacitor DC converter.

The thing is a CF bulb has little load. A 13~14W CF on a 350W inverted
12VDC supply is not going to have a load. Therefore going from 13~14W
CF to 26~28W from two CF bulbs should not go from a condition of light
production to not producing light. Therefore there has to be some other
condition involved. Especially considering I took a 36W LED Rope Light
( Orange LEDs for Halloween ) and also put it on the Inverter and it
worked if I had 1 CF or 2 CF bulbs on the circuit. It was only the two
CF bulbs that interacted with each other.

"Although the average power consumed by the CFL is 21.2 watts,
the peak current is 1.17 amperes. And, current is drawn only
for 2.6 milliseconds for each half-cycle."

If the device feeding the CFLs is sensitive to the
instantaneous current flow. that might be enough to
trip a protection feature.

Since any file can be named anything, Google searches are pointless. In
fact there are shill sites setup that are deliberately providing faux or
incomplete information as an impetus for you to download SpyHunter for
generating Enigma affiliate revenue.

If you have a file, provide it to me or you can upload the file to
http://uploadmalware.com and let me know you uploaded a sample. I will
analyze it and give you a report.

The file is also 4 years old. Detections are mostly based on what looks

While that sounds plausible, I don't think that's it. It was running on
a deep discharge marine battery and the Tripp-Lite has a 40A fuse. I
can't see how a 3ms surge of 180 watts would make it such that a second
CF can't be used. This is when, on the same circuit, other loads don't
have an issue such as the 36W LED rope light. I also had additional LED
"night lights" on the circuit.

The CF bulbs do act strangely. In a dissimilar situation I have a
ceiling fan that used a RF remote. The remote turned on the light
and/or fan as well as it having a dimmed light mode. It was unknown to
me that this unit had that capability. That is until I was burning out
CF bulbs in ~48hrs. When I put my DMM up to a light socket, unloaded I
was only getting ~78VAC. When I put a load on it, that would drop to
something like 65VAC. It was then I realized there must be something
inline that was failing. Once I bypassed that wireless remote control
unit, I no longer had problems. When I researched the unit, I saw that
it was only to be used with incandescent bulbs. Over a period of 8
years, CF bulbs aged the unit until it was failing.

Thanks for all the responses.

I needed a true RMS voltmeter.

Another of my meters was and voltage measured 114 V which is well with specs.
