Can low-energy light bulbs be run okay from modified sine wave
inverters (attached to a 12v battery supply). I've heard there's a
problem with fluorescent tubes and this setup. And as low-energy light
bulbs seem similar in design and light quality I was just wondering...
here is what one maker has to say about it:

Here are a few pointers about which kind of inverter to use:
In general, any device that senses either voltage peaks or zero crossings
could have problems when running from MSW. Devices such as these should be
run from TSW inverters. Ham radio and CB radio operators may notice RF
noise from MSW inverters; in that case do not run the radio and the inverter
at the same time. Electronics that modulate RF (radio frequency) signals on
the AC line will not work and may be damaged. You may notice hum or buzz in
the audio of TV's, radios and satellite systems used with MSW inverters.
Audiophiles or professionals using sophisticated audio, remote measurement,
surveillance or telemetry equipment should use TSW.
Examples of problem devices are motor speed controllers employing triacs,
and some small battery rechargers that do not incorporate a transformer
between the utility power and the load. To help you visualize this, if
there isn't a 'wall wart' between the battery charger (or the battery in the
device) and the AC plug, don't use MSW.
Please note two other common problem loads, electric shavers and emergency
flashlights. Both of these items have batteries in them but connect
directly into the wall to charge, without an external transformer. Don't
use items like these with an MSW inverter. If you do use an MSW inverter
with a transformer-less charger, your product will likely be damaged.
Garage door openers, laser printers and large strobes used in photography
have all been reported as trouble loads for MSW inverters; they either don't
work at all or stop working entirely, so don't take a chance - use TSW.
As a general rule, products operating through an AC adapter will work fine
from an MSW inverter. These include laptops and cell phone chargers, video
games, camcorder and digital camera chargers. Televisions generally work
well; some VCR's with inexpensive power supplies run poorly. Consider
switching to another brand of VCR in that case.
