What is so special about the light from a laser?
it's monochromatic(all exactly the same wavelength) and every photon is in phase with all of the others(so, unlike ordinary light, all of the waves travel with the same wave shape) and it's a parallel beam, so the light doesn't diverge this means a 25 watt laser can cut through steel while an 80 watt light bulb can't it also means a 25 milliwatt laser leaves a brighter spot of light than an 80 watt light bulb(you can see the laser in the normal light) it also enables you to make a hologram it allows for lasersurgery
How much would leaving on a 60 watt bulb all year cost?
There are about 8760 hours in a year, so running a 60 watt bulb for a year would consume (60 times 8760) or 526000 watt hours. Electric power rates vary, but at $0.15 per kilowatt-hour, that would be almost $80.
How efficient is a light bulb?
An incandescent bulb is 96% efficient as a heater, and 4% efficient as a source of light. A fluorescent bulb is only 60% efficient as a heater, and 40% efficient as a source of light. An LED bulb is only 10-20% efficient as a heater, and 80-90% efficient as a source of light (but that light is usually unidirectionally directed... harder to do diffuse lighting with them).
What temperature is considered hot?
About 80-100F is considered hot. I suggest you go to Las Vegas or Honolulu for that weather!
What is the wasted energy in a torch?
The main wasted energy is the heat generated in the bulb. If it is an incandescent bulb 70-80% of the total energy from the battery is wasted as heat.
Can you use a 120 watt equivalent 80 watt actual usage in a 100 watt reptile light fixture?
A reptile light is used to generate heat for the reptile, so you must use a bulb that uses 100 watts, and an incandescent bulb is what you need.
What does 40 watts bulb mean?
An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.
Compare and contrast a 60 watt and 100 watt light bulb?
The more energy that is transferred in a certain time, the greater the power. A 100W light bulb transfers more electrical energy each second than a 60W light bulb.The equation below shows the relationship between power, potential difference (voltage) and current:power (watts) = current (amps) x potential difference (volts)
What type of light is a 20 watt energy saving bulb Halogen Incandescent neon or fluorescent?
A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts. A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts. A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
How much energy does a CFL light bulb save versus an incandescent bulb?
About 80%. An incandescent bulb produces 12 lumens per watt, (15 for halogen) while a CFL produces about 60 lumens per watt.

How many amps does a 175 watt mercury vapor light use?
depending on voltage supplying the bulb, each ballast spicifies on it such rating. many ballasts have better efficiency at higher voltage. however; say 175 watt bulb, 120V with 80% efficiency= (175/120)/.8=1.82amps
What kind of battery can power a 40 watt light bulb?
If the bulb is a 40 watt, 120v bulb, you would need 20 6 volt batteries wired in series, or 80 (!) 1.5 volt batteries. 1.5 volt batteries are AAA, AA, C, D, etc. Since this solution is rather extravagant, try finding a light bulb made for an RV. These typically run off of 12 volts, and you can get a single 12 volt battery, or 2 6 volt batteries, to run this bulb.
What is most energy efficient led lamps or bulbs?
The most efficient outdoor light bulb would the 5 watt Light emitting Diode light bulb also know as the LED bulb. They are small lights with miniature sockets or made to fit into conventional sockets.
How hot is a 50w heat lamp light bulb in Fahrenheit?
I use a 75 watt heat lamp in 36" habitat. at the end i use it on, it is about 80-82 degrees. it depends on how far away the bulb is and how the temp. is naturally. so don't place it close enough to get touched or burned by whatever your warming not burning. Hope this helps a bit. not a professional. Just experienced this much.
What is the average energy energy consumption of an energy saving light bulb?
Fluorescent lighting is much more energy efficient than incandescent lamps, usually by as much as 60 to 80%. That also translates into a corresponding energy savings. I don't recall the exact figure off hand, but the light output from a fluorescent lamp is about three times it's rating. For instance, a 40 watt fluorescent puts out the equivalent light of a 120 watt incandescent bulb.
Can you add headlights to a Yamaha grizzly 80?
yes but they have to be a small pair i have a pair of 40 watt light on mi grizzly 80
