How much $$$ can you save on your Electricity Bill
Power Consumption of a Normal Signage
A sign built with eight fluorescent 40-watt lamps remains on for 10 hours a day, 365 days per year, and the energy use cost per kWh is 19 cents.
The calculation–8 lamps X 40 watts each = 320 watts; divided by 1,000 = 0.32 kilowatts; multiplied by 10 hours = 3.2 kWh; multiplied by $0.19 = $0.61 per day; multiplied by 365 days = $221.92 per year. Info taken from Gigantic Signs.
Power Consumption of an AllNightGlow Signage
Using a ratio of 5 seconds on to 5 minutes off, an All Night Glow Sign can glow for one hour with only one minute of power consumption.
|
Charge Time *(Consumes Power) |
Glow Time **(Free Light) |
| *Lights On for 5 Seconds | **Glows Brightly for at least 2 Minutes |
| 24 times in an Hour, 5 seconds each time, 24 x 5 = 240 seconds (2 minutes) |
60 minutes / 2 = 24 times
|
| 2 Minutes Total Charge Time | = 1 Hour Glow Time |
| 20 Minutes Total Charge Time |
= 10 Hours Glow Time |
So, a sign that needs to be lighted for 10 hours as in the example above, now only consumes power for 20 minutes, with AllNightGlow.
The power consumption is now at $0.04 per day; multiplied by 365 days = $15.00 per year.

Using the ratio of 5 seconds charge to 2 minutes glow.. Consumes Power for only 20 minutes, |
| Energy Costs $0.61/day | Energy Costs $0.04/day |

Power consumption per year $221.92 |
Power consumption per year $15.00 |
Average yearly savings on electrical consumption,
for just one sign is $222 – $15 = $207
