So has anyone dabbled in electricity costs for their tanks?
My approximate electricity rate is 11.6 cents per kWh. That means 11.6 cents per 1,000watts. That's 0.0116 per watt.
(4) 24" VHO bulbs - 74w x 4 x 8 hours = 2368Wh per day
Mag 9.5 - 93w x 24 = 2232Wh per day
Mag 7 - 70w x 24 = 1680Wh per day
(2) Kolaria 750 - 4.5w x 2 x 24 = 216Wh per day
300w heater - 300w x 12 hours = 3600Wh per day (just a guess, not sure how often the heater is on during the day)
Total = 10,096Wh per day. 10,096 / 1000 = 10.096kWh per day.
10.096 x 11.6 cents = 117.1136 cents per day
$1.17 per day
$35.10 per month
$421.20 per year
One thing not mentioned in this equation which was pointed out by Floyd R Turbo, the ballast is not figured in.
I read that the IceCap power factor is around 60%. I'm using the IceCap 430-008 on my setup. Someone running (2) 39w T5s was actually pulling 2.12A at the AC outlet. How does that work? 2.12A @ 120v is around 254 watts right? Factor in that power factor and you're down to around 152 watts. Is the ballast really soaking up 176w or is it actually over driving the T5s?
