the E-Cono 150w ballast pulls 4 amps at start up and 3.5 constantly after being on for a couple of hours
this isnt true...... here is some info I've found on other sites please read and dont be a jerk be positive
this is a simular argument from another site read the whole thing.......
Hi everyone.
Just a head's-up on the E-conolight 150s; I fell into the cheap-price trap like so many of you (I bought four of these pigs), but do you guys know to light the 150 watt bulb, the E-conolight 150 watt ballast kit (Caster or Castor is the brand name) uses
Over 350 Watts!!! Kinda blows the savings in the first month of operation. Any low-wattage HPS that doesn't have a seperate capacitor (two main parts instead of three; ballast,capacitor, and ignitor), you can count on being power hogs. This includes most "security" lights you rewire to remote the ballast.
A better option is to get a 150 w Venture ballast kit (
www.businesslights.com has good prices; just $12 more) that uses only 166 watts to light the 150. Power Factor is @ 90%.

Hi Vern Equinox,
I posted on this in the OG days and I will explain again here;
The 350 watts you talk about is the total through put of the lamp - it still however only uses the same amount of wattage.
Think of it this way... each lamp is like a closed loop circuit...
when a lamp and ballast have a low power factor they pull more electricity through the ciruit - a portion of this is used to light the lamp - some of it is returned (not used) through the plug back to the line.
when a lamp and ballast has a high power factor the amount of energy returned (not used) is less and less power is pulled out of the wall.
Basically what the capacitator does is store and regulate charge allowing the lamp to only draw what it uses.
The power factor is the ratio of power drawn to power used.
Your power company charges you for how much you use, not how much you draw.
so in no way will your power bill be equivalent to running a 350 watt lamp as you imply.
Your power bill will be the roughly the same with either 150 lamp.
It should however be noted that the power company does have the ability to see the overall power factor of your ciruit and if you were to have as you do 3 or more of these plugged in it could be noticiable to them. The original author made this point and basically said that if you ran a single 150 it shouldn't be a concern but if you were planning on stringing together multiple 150's, 100's, or smaller lamps it should be looked at.
incidentally if you wire your lamps to the same plug you only need a single capacitor between the line and the first ballast to increase the power factor of all the lamps.
That all being said the Venture is probably a better lamp and I would pick it over the econo-light given the choice. Thanks for the link!
