coreefer and others with 120s

[rekn]

if you dont mind me asking, how much is your electric bill?

im getting a 120 and trying to budget in the cost of mh and such for a 120

 

[CastleRock]

Mine runs me around 65 extra a month but im in Castle Rock not sure what your KWs cost in the springs

 

[COreefer]

I really couldn't tell you...I've never really sat down and tried to determine this.

 

[rekn]

ok =(

i asked you specifically because

"120g reef tank,40g sump, 4x150wHQI's, mainly SPS"


thats oddly the same tank i want
:fun5:

 

[COreefer]

yeah...I just don't even have a ballpark. Perhaps a guy like Russ who works with electricty can give you a guideline.

 

[Deuce67]

Determine how much CS utilities charge per KW. It will be on your utility bill. Then use this electrical calculator

 

[Crit21]

Well, if you want SPS, you need to pay the electrical piper.

 

[racer69]

Wouldn't 2 250's use less electricity? I don't know for sure, but maybe Russ will know.

 

[Deuce67]

2 250s will draw less than 4 150s depending on the ballast.

 

[murfman]

hmmmmmm 4 x 150 = 600, 2 x 250 = 500 and Todd is an engineer ;=P

 

[Crit21]

The wattage of the bulbs does not necessarily equal the power consumed. Don't forget that the power supplies lose energy as heat too. Power consumption of a 150W ballast can be higher than the 150W the bulb itself uses.

 

[murfman]

If you want to calculate your power consumption, take all the accessories you are going to be running and add them up. X that by how many hours a day you will be running them and that will give you and Idea of how much you are consuming. Then figure out what you are paying per KW.
