A halogen bulb IS ITSELF a type of incandescent illumination source.
A 40 Watt traditional incandescent bulb usually emits about 400 to 500 lumens while a halogen may emit close to twice that. So a 25 W halogen might give out as much light as ah older style 40 W bulb.
A watt is 1 volt x 1 amp. Your question doesn't contain enough information. You would need to know the resistance of the bulb, which is related to the design.
It will vary by bulb design, materials and glass opacity.
Halogen+++No longer. LED-based fluorescent lamps use a lot less electricity than halogens for similar light levels - much of the energy emitted by a halogen lamp is heat, although it is more efficient than the equivalent argon-filled incandescent lamp. (A halogen bulb is still an incandescent type - it simply uses a different gas filling from the conventional bulb.)
Wikpedia says that halogen lamps produce about 19-20 lumens/watt. If you have a 500W lamp then you get 9500-10000 lumens.
Halogen lamps run hotter than conventional incandescents, and as a result of their hotter filaments, emit a whiter light with more of the light in the visible range, and less in the infrared. A typical 50W halogen emits between 800 and 950 lumens.
A halogen bulb uses a filament that has electricity passed through it to create the light. The halogen name comes from the gas the filament is enclosed in to prevent it burning. 'Xenon' bulbs can refer to either bulbs with a filament enclosed in xenon gas, or to a HID (High Intensity Discharge) bulb. HID bulbs work in an entirely different fashion. The light is created by passing an arc of high voltage electricity through a blend of gasses (primarily xenon) and metal ions. The light produced is powerful and uses less energy than the equivalent halogen bulb, so they are becoming more common in cars and other applications.
yes you can
Halogen bulbs are about 30% more efficient so a 70 watt halogen does the job.
Yes, the halogen bulb would provide about 30% more brightness (lumens) for the same electric power rating. So 70 watt halogen is about equal to 90-100 watt incandescent.
55-watt
It is equivalent to a 75 watt incandescent bulb
Halogens are about 30% more efficient so 300 watts incandescent is equivalent to about 210 watts halogen. It's also equivalent in brightness to about 60 watts CFL.
Incandescent produces about 10 lumens of light per watt of electricity Halogen produces about 13 lumens per watt Fluorescent and CFL produce about 50 lumens per watt So Fluorescent is the most efficient.
Strictly the power in watts measures how much energy is used, while the brightness is measured in lumens. Bulb packaging should carry that information. But 'equivalents' are a useful way for manufacturers to bamboozle customers, so halogens often carry an 'equivalent wattage' figure, which means the power of an ordinary old incandescent bulb of the same brightness. If you had a 100 watt old-fashioned bulb, that is replaced by a 70 watt halogen. It could also be replace by a 20 watt CFL bulb that is obviously less expensive to run and lasts much longer.
Yes. It just won't be as bright.
About 80%. An incandescent bulb produces 12 lumens per watt, (15 for halogen) while a CFL produces about 60 lumens per watt.
It varies from about 600 to 1100 lumens. Typically the higher the lumens output, the shorter the lifespan of the globe. Have a look at this list of globes for purchase whih shows wattage and lumens: http://1000bulbs.com/category/75-watt-incandescent-standard-shape-light-bulbs/
A 13 watt cfl is the same as a 60 watt incandescent. So find an led bulb that is equivelant to a 60 watt incandescent
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.
