Are high pressure sodium lights expensive to run?
High Pressure Sodium lights have a high maintenance cost, because they require monitoring and more frequent replacement of both bulbs and parts.
How much power does a sodium light use?
A high-pressure sodium street light can draw up to 1000 watts, and an incandescent light used in the 1900s needed 320 watts. Some LED street lights require only 73 watts and, according to the U. S. Department of Energy, produce a higher quality of light.
Do sodium bulbs use a lot of electricity?
Sodium lights operate in a range where the human eye is very sensitive and so there is less power required to achieve the same lighting effect. For this reason they are very efficient.
How much does it cost to run a high pressure sodium lamp?
Grow Light Operating Cost
| 1000 watt Sodium | 600 watt Sodium | |
|---|---|---|
| Ballast Wattage | 1100 | 665 |
| Cost per Month | $52.80 | $31.92 |
| Initial Lumens | 130000 | 89000 |
| Mean Lumens | 126000 | 81000 |
What is better metal halide or high pressure sodium?
Metal halide is much less efficient than high pressure sodium–MH produces much less light per watt; MH produces more glare due to the blue light component and increases adaptation time; MH more effectively shuts off melatonin production which can trigger tumor growth; MH contains more mercury within the bulbs; MH …
Is high pressure sodium more efficient than LED?
LEDs are much the same. Though they’re generally more efficient than HPS (with some clocking 2.8 µmol/joule), some LEDs are less efficient than high-quality HPS fixtures, and they give you less light.
How much does it cost to power street lights?
The average price in the USA is 10 cents per kilowatt-hour ($0.10/kWh). Consumption for 12 hours is (12 hours*100 watt) = 1200 watt-hours = 1.2 kWh. So daily Electricity cost is (1.2 kWh*$0.10) = $0.12. Monthly Electricity street light cost is ($0.12*30) = $3.6.
How much electricity does a grow light use?
This means the light consumes 0.68 Kilowatts (Kw) per hour. Multiply this number by the number of hours the light is on per day (ex:18 hours per day during vegetative growth. Multiply the total kilowatt-hours (kWh) by your electrical rate.
