400w HPS, how much will it cost in electric..? Report Abuse. Your 400 watt hps lamp will operate at 468 watts if you include the ballast. If you run it at 120 volts and if you live in the Midwest, it should cost around 8 cent per hour to run. The hps is not a grow lamp so you will not get anything to grow under this lamp. Hps is the worst on the color spectrum for light output.

- It accounts for 30% to 40% of the total energy consumption in office buildings. The annual lighting electricity consumption per square meter of the building varies between 20 to 50 kWh/m 2, a (SEA 2007, STIL 2007).

- So when a 100watt lamp is switched on , 100 watts of electrical energy is converted to 100watts of light and heat ; a 50watt lamp produces a total 50 watts of light and heat , and so on . * However , some lamps are more efficient at producing light than others ; this determines how much of that 100 watts is transformed into light , and how much is  ...

How Much Light Do LED Bulbs Produce? Put another way, LEDs use about 12% of the energy used by halogen and filament bulbs to emit the same amount of light. We can also calculate that a 50 Watt halogen spotlight produces about 600 lumens. An LED light would need to be about 6 watt in power to produce the equivalent 600 lumens produced by a 50 watt halogen. We can now see clearly that a 3 watt LED spotlight would produce 300 lumens, not 600 lumens, so definitely not equivalent to a 50 watt halogen bulb.

Watt For another example, when a light bulb with a power rating of 100 watts is turned on for one hour, the energy used is 100 watt hours (Wh), 0.1 kilowatt hour, or 360 kilojoules. This same amount of energy would light a 40-watt bulb for 2.5 hours, or a 10-watt low-energy bulb for 10 hours.

- The power consumption of the lamp itself is about 200 watts, with a power-factor of 0.9 resulting from the voltage wave-form. The luminous efficiency of the lamp is, therefore, about 50 lumens per watt. The over-all efficiency is reduced to about 40 lumens per watt because of the auxiliary equipment required.

Incandescent light bulb The remaining energy is converted into heat. The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared with 60 lm/W for a compact fluorescent bulb or 150 lm/W for some white LED lamps. Some applications of the incandescent bulb deliberately use the heat generated by the filament.

- An average CFL bulb which provides 800 lumens will use only 13 to 15 watts compared to a similar incandescent bulb which uses 60 watts. Click calculate to find out the electricity cost of a single CFL light bulb running at 14 Watts for 5 hours a day @ $0.10 per a kWh, you can also modify the calculator.

- Some examples - (See chart below for the math equation) A light bulb is typically 60 watts; leave it on for an hour you have used 60 watt hours, or .06 kWh A typical personal computer uses approximately 70 watts. In addition, a 17 monitor uses another 80 watts. That comes to 150 watts in an hour, or .15 kWh.

- Watts are a measure of power, not brightness. A 15W fluorescent bulb can be as bright as a 60W incandescent bulb, since fluorescent bulbs are more efficient. LED light bulbs are even more efficient, and can produce the same brightness for less than 8 watts of power. Do not believe the myth that leaving fluorescent lights on saves money.

- Capacity (Wh) is the energy stored in the battery. Wh is Watt x hour. Power (W) can be considered as the speed of drawing the energy. W is Watt. Maximum Power (W) your battery allows to draw is indicated at the specifications of your battery.ou can use the Li160S battery to power the camera and light: 23W + 20W = 43W. The 160Wh battery will last for approximately 160Wh / 43W = 3.7 hours. To power the 43W system for 5 hours, you would need Capacity of 43W x 5 hours = 215Wh.

Solar Powered Grow Room Your average daily power consumption will be expressed in watt hours per day. (watt-hours or wh). RULE OF THUMB: LED lights use less energy and produce more light with lower wattage, a rule of thumb to use is that for every 240 Watts of high powered LEDs you get the equivalent of 1000 watts.

Fluorescent lamp A fluorescent lamp converts electrical energy into useful light much more efficiently than incandescent lamps. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output.

Q & A: Energy of a Lightning Strike A: Dear Lee, The energy of an average 3 mile-long lightning strike is one billion to ten billion joules. To keep a 100-watt light bulb going for one second, one hundred joules of energy will be used. With one billion joules, the light bulb will be lit for 116 days. (published on 10/22/2007).

- The LED light bulb itself costs about $30 up front. It uses 12W of electricity, which adds up to 300kWh over 25,000 hours. That’s about $30 in electricity, vs. the $164 needed to power the 65W incandescent light bulb.

- LED Lights generate very little heat, which means LED Lights are 90% energy efficient. LED Lights last greater than 60,000 hours. LED lighting last up to ten years or longer! The standard incandescent light bulb last 1,500 hours.

Comparing lumens and candlepower? Re: Comparing lumens and candlepower? Sorry for the runaround on this can of worms. 50 W HID gives you 20 million candlepower and 4500 HID lumens gives 15 million candlepower, so your light puts out somewhere between 20 and 15 million cp. Let's say 17 million, but because there is a wide tolerance on this value.

- A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you'll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.

How much does a street light cost per hour to run? Report Abuse. Assume that a typical street light requires about 150 watts of power and burns an average of 12 hrs per day. That comes to 1800 watt-hours, or 1.8 kW-hrs.Further assume that electricity costs about $0.11 per kW-hr.With these assumptions, the daily cost of electricity is about $0.20, and the average hourly cost would be a little less than a penny.hile a 150-watt sodium vapor light throws a lot of light, and many boxy light packs on the sides of buildings are that wattage, I believe street lights are closer to 300 watts in power consumption.

Wattage vs Lumens: Know the Difference for Better Lighting The ASL fixture provides replacements for 150 Watt, 250 Watt and 400 Watt HPS and MH lights using fixtures with a Wattage of 62 Watts, 123 Watts and 181 Watts. In the end, taking into consideration the lighting levels and Lumens over the Wattage of the lamp will provide a more energy efficient lighting system.

LED grow lights : CFL grow lights run much cooler than MH or HPS, so can be placed closer to the plants. Several manufacturers are now producing CFL more in tune with growing plants, including producing light into the orange end of the spectrum.ED grow lights run on around 50% of the electricity when compared to the same HPS grow light so a 500 Watt (true draw) LED grow light will offer better output in terms of yield than a 1000 Watt HPS unit.

LED Traffic Signals The energy saving for the LED signal is significant. The LED traffic signal bulb uses approximately 15 watts of power, compared to the average of 100 watts of power used by the traditional incandescent halogen bulb. Each traffic signal operates 24-hours per day, every day of the year. The cost to power a single 100-watt incandescent red bulb each day is about 15 cents (2.4 kilowatt hours), based on the current average of 5 cents per kilowatt hour which the City of Yakima pays.

Since 1996Seeds Hydroponic Systems Indoors Outdoors Grow Lights Forum High Pressure Sodium (HPS) Grow lights. High pressure sodium marijuana grow lights are a good choice for a lot of people, they have been used for growing marijuana indoors for decades. However they are not brilliant at transferring electricity into light and waste a lot of electricity on producing heat instead.

MH & HPS Grow Lights for Cannabis Electricity Use & Heat are similar to CFLs watt-for-watt-HID grow lights will produce about the same amount of heat as the same wattage worth of CFLs, but you will tend to get bigger yields and better results with HIDs. So for example, let's say you purchased 7 x 23W CFLs(161W worth of CFLs).allast-MH/HPS grow light systems use bulbs with big bases that can't connect to a regular light bulb socket. Instead, they use a socket which requires a special ballast to start and maintain their arcs for power.
