The thing with flourescent lights that caused noise in music equipment and microphones was the type of transformers-called ballasts- that they used. The type of voltage and the frequency of the output of those ballasts was the culprit. Much of the newer stuff is much cleaner but still iffy. The small bulbs you are talking about are considerably lower in voltage. They might not be noticable. I can hear them and thus don't use them. While creating music, you may run into harmonics bleed problems with them.

I wish I knew more details about LED lighting and if they created any line noise. That's what I'm thinking of running at home in my new play area.

They are expensive, but come with a very long warranty, and the thing I like most is, they run very cool. Essential with a DAW, Amp, 300lb guy, and all kinds of gear running in a tiny room.

Re:Do CFL light bulbs cause interference when recording? 2012/10/02 17:49:14 (permalink)
My whole music building is lit with LEDs.

Each time I replace one of our house bulbs with a tungsten that I have left over I think, "Jiminy crickets... I could throw this brand new tungsten bulb in the trash right this second and save money"

It seems like LED household bulbs have finally come of age and the price is covered by the energy cost saving in less than a year if you use the light frequently. After they are paid for by the energy savings you should get many more years of use while continuing to save money on energy.

The irony is that gifting my N.O.S. tungsten bulbs to someone who can't afford to purchase the LEDs perpetuates the fact that they are spending so much on energy that they can't afford to purchase the LEDs. So I'd rather toss 'em out.

It's a catch22.

My music building uses only 25% of the amperage the lights use to draw and it has just as much if not just a bit more light than was made by the tungsten bulbs using 4x the power.

Plus they run cooler so the AC runs cheaper.

It's no brainer even if you just buy one or two $10 LED bulbs at a time and slowly make the transition. Eventually you'll get to the point where you look at your last few tungstens and think the same thoughts I've been having. It's cheaper to throw them out than use them.


best regards,
mike

I got to use my Arrisun 5 Hydrargyrum medium-arc iodide light on a furniture store shoot this morning.

It's bright enough to give you a sun burn and only uses 575 watts.

The CFLs have little tiny switching power supplies that take the place of the traditional magnetic ballasts.

The magnetic ballasts are safer, less prone to bursting into flame, and less prone to melting than the switching power supplies, but they spray Electro Magnetic Interference into your audio electronics.

That's why older florescent fixtures have the reputation of adding noise to audio circuits.

The CFLs don't exhibit that problem because the switching power supplies, which produce EMI and RFI as well, are routinely and effectively filtered for the EMI, and sheilded for the RFI protection by the manufacturers.

mike

Thanks Mike!

Typical!
 
Nobody pays attention anymore like they did in the old days.
 
I blame it on the cumulative effects of all this new-fangled lighting.

Sorry, as I was shoveling through the unrelated crap posts, I must have missed it.

On a related tangent however, why wouldn't a CFL lava lamp work?  CFL's still give off a lot of heat (it's just disapated more because of the additional surface area - they aren't completely cool like LED's).  Heck, you could afford to leave 'em on all the time then!

Re:Do CFL light bulbs cause interference when recording? 2012/10/03 08:53:18 (permalink)
from wiki:

"The bulb is normally 25 to 40 watts. It may take 45 to 60 minutes for the wax to warm up enough to freely form rising blobs (depending on the original temperature). It may take 2 to 3 hours if it has been in a cold room for a long time depending on the temperature."

If you use a house hold incandescent bulb that draws 40 watts, perhaps 35watts are converted to the form of energy we call "heat". I don't have any exact figures at hand but that's pretty close.

If you use a CFL bulb that draws 40 watts less than 20 watts are converted to heat, and the bulb will be relatively brighter as the remaining energy is more efficiently converted to "light".

That's why we use lower wattage CFLs to get the same amount of light that an Incandescent puts out.

So you'd need to find the wattage of CFL bulb that produces the same amount of heat to achieve similar performance. Maybe a CFL that draws 80 watts?

If the primary goal is to use the bulb as a source of heat... the incandescent is the more efficient choice.

If the primary goal is to save on power consumption then the lava is going to take longer to "flow".

:-)

mike

I missed it, too.  I must have thought I was in the FSF and skimmed over it.  At least it must have been a good idea if we both thought of it.

The first thought gives me too much credit and the second sells Mooch short.
