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.
250W halogen lamps for specialty uses (theatrical, aircraft, etc.) are available that output as much as 9000 lumens, but may be quite costly, require an unusual fixture, have a short lamp life, or all three. 250W halogen lamps available for consumers output as much as 4300 lumens for a double ended linear T3 (3mm diameter tube style) or 3600 for the common PAR38 outdoor flood or as little as 800 lumens for a premium 24v MR16 lamp or 550 lumens for a more ordinary MR16.
A previous version of this answer erroneous stated a 250W MR16 halogen lamp output 15,000 lumens possibly due to confusion of total light output in lumens with peak beam intensity in candlepower or lux.
11W is not a standard incandescent lamp. Assuming you meant to ask about an 11W CFL (equivalent to a 40W incandescent), the lumen output will be around 650. (CFL means Compact Fluorescent Lamp)
go to http://www.1000bulbs.com/Halogen-Light-Bulbs/?gclid=CM2j-e_W_pECFSOsGgodxSe29g click on a lamp and you will get the lumens
Aprox 35 lumens in an incandescent 7 watt light bulb
Incandescent: 10-12 lumens/watt
Halogen: 15 lumens/watt
CFL: 50-60 lumens/watt
LED: 50-60 lumens/watt, some manufacturers claim more.
Approximately 3400 lumens initially.

1700
Wikpedia says that halogen lamps produce about 19-20 lumens/watt. If you have a 500W lamp then you get 9500-10000 lumens.
No, calcium is not in the halogen group. The halogen group is made up of fluorine, chlorine, bromine, iodine, and astatine.
Halogen refrigerants are also known as coolant chemicals, which can cause ozone damage. A great example of a common halogen refrigerant would be Freon.
yes you can
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
250W tungsten halogen gives around 10,000 lumen. 2 x 39W T5 fluorescents gives a total of between 4,000 to 6,000 lumen.
6500lm to 7000lm
Should be about 850 lumens. The same brightness is produced by a 15 watt CFL.
It depends on the type of GU10 lamp - an GU10 LED will have a lower power usage (cheaper to run) but lower Lumen output. For example a 3W GU10 LED lamp in warm white has an output of about 150 Lumens. For a halogen GU10, a 35W bulb will have an output of about 600 Lumens. For more powerful lamps, expect a higher Lumen output. Finally you have an option such as a low energy GU10 such as the Megaman, which for a 7W power value gives an output of 620 Lumens, which exceeds that of the halogen bulb and also has a longer life.
10-11 lumens per watt for incandescent bulbs 13-14 lumens per watt for halogen 50-60 lumens per watt for fluorescent

The energy consumption of a modern Cree XP-G or XM-L based flashlight with 170 lumen output can be as low as 1.4 watts with 120 and more lumen per watt. The light output will be approximately equal to a 20 W tungsten incandescent light bulb or a 10 W halogen light.
There's a range of products in each category and incandescent lumen output degrades more quickly than halogens due to typically short lamp life. Try this for a start. "14-17.5 lumens per watt for standard "A19" 120 volt 60 to 100 watt incandescents, and typically 16 to 21 for most halogen lamps." Conceivably, you could get 210 lumen output in a 10w halogen and as much as 1050 lumens out of a 60w incandescent. MR16's list beam power, rather than lumens because they are so focussed and directional.
around 20
From 550 to 750 lumens
Generally the lumen output of bulbs is proportional to the power used, if the bulbs are operated at their rated voltage.
It depends on the specific lamp. The packaging the lamp comes in should tell you what the lumen output is. This in a common question as people want to compare LED replacements. You can use 600 lumen as a good guide for comparison for a 50 Watt halogen.
