This latest video is a tutorial we made to help teach you about Power Factor. In the next few weeks we will be releasing information on how you can easily modify your current electronics to make them the most energy efficient.

I was astonished to find out we were paying so much more for the cfl's than what the boxes say you will pay. So me and Imhotep and working to correct this for everyone.

Yes yes ...
I'm an EMPTY vessel waiting to be filled ... :lol:

The CFLs would be nice, but is it easier to learn
how to fix a refrig, toaster or fan?
Things in the house that have a plug, fixes which
do not require accessing internal parts of the unit.

Close would good, not needing fine-tuned PF correction with harmonic this and that.
I'd like improved PF to save money, with the understanding that perfect PF tuning is
more difficult to learn and archive??

I'll buy a kill-a-watt meter ..
but I need to know how to go about reducing the PF.

I know capacitors .. that's it. ahhhhh !?

Could not a bank of capacitors, an "evaluation box", be used like
they are using in the RotoVerter projects to roughly determine
what would be close enough ?
Then build a box just with a single capacitor for whatever you evaluated?
Not a box with an outlet to plug into, but reduce the cost by a box sliced into the
wire of the item being fixed.

Hello Shiva and Imhotep. Thank you for informing us all about the power factor issue in CFL. Now that we know we are getting ripped of by the power companies (or CFL companies depending on how you look at it) I am excited to go and test different bulbs to see what the apparent power is. There are many different kinds of LED bulbs available, with huge price differences and I would like to test several ones from different manufactures.

Where can a find a device like the one that you have to display the Volt Amperes?

I have tested a few LED bulbs only by how it makes my wife and I feel. I can tell you that all of the cheap LED bulbs make us nauseous, within just a few minutes. But the expensive bulbs, like the Philips LEDs do not. In fact, they feel quite pleasant. I have noticed that the Philips LEDs are very heavy and while I have not disassembled one, I am hypothesizing that their bulbs are incorporating a small transformer to convert the electricity back into DC before it gets to the LEDs. As such, as I am guessing that the cheap bulbs, since they are using straight 120V 60 hertz AC, are making us sick because of the nature and frequency of the alternating current.

I would be really cool if someone else could confirm this.

I'd send a PM Maui, or an email.

Better lighting circuits are likely being done with the Joule Thief circuits,
the output to input ratio seems to be really high, even higher than an IROL setup!

I think you can get those Kill-A-Watt meters @ Menards, Lowes, etc.
Or at an electrical supply store. Online at least...

Hello I just recently replaced almost all the lights in my house with cfls and now I found out that I am paying double what I should be paying. My question is if I install a power factor correction device (such as http://www.saveenergyllc.com/) in my house will it have any effect on cfls or do they only work on inductive motors?

Well, as I remember, PF has 2 manifestations, and Capacitive Loads offset Inductive Loads,
meaning that any PF costing you $$$ is Inductive and I have seen huge Capacitor Banks
in industrial situations to save money, so in theory, this could do it! Call the manufacturer
and ask them to back it up with a guarantee, and don't forget to call a Union Electrician
to install it! (Or learn to DIY it, not that hard, but you need to pull the meter)
LMK what you decide...

I looked at the instrux, SUPER SIMPLE!!! You DO NOT need to pull the meter!

For something cheaper, we can always do crude method:

Hello all,
I learned of power factor correction from a a fellow engineer who apprenticed with a cranky old curmudgeon named Henry Kuhn who was a genius broadcast Engineer back in the day. He designed some of the best super regenerative radio recievers ever made. Examples of his work are in the Smithsonian. He did work for the U.S. Navy on the Eldridge- he built the de-gaussing coils. He actually got to work with Tesla a few times.
All over his shop he had banks of various sized capacitors set up to run in parallel with whatever appliance he would need to use at the time.
The moral here is you want to use your kill a watt to check your PF and add capacitors to correct it to what is needed. Add the caps in parallel to the load.

Also a heads up on the Kill a watt EZ Home Despot has just dropped the price from $49.00 to $29.00- such a deal.

I have taken several CFL lamps apart after they were dead and it is apparent that there were spaces for capacitors to be mounted to the board but were not there. Hmmmmm.....
I will have to check the next batch of bulbs I buy withe the extreme utility rebate promotion.
I bet they too are missing components.

Kind regards,
ZathEros
