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.
Wikpedia says that halogen lamps produce about 19-20 lumens/watt. If you have a 500W lamp then you get 9500-10000 lumens.

maybe iodine.
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
Chlorine belongs to the halogen family of elements.
Two 39W T5 fluorescent bulbs would produce more lumens than a single 250W halogen bulb. Each 39W T5 fluorescent bulb typically produces around 3300 lumens, totaling to 6600 lumens for two bulbs. On the other hand, a 250W halogen bulb typically produces around 4500 lumens.
Should be about 850 lumens. The same brightness is produced by a 15 watt CFL.
A 250W halogen bulb typically produces around 5000-6000 lux at a distance of 1 meter. Lux is a measure of illuminance, or the amount of light falling on a surface.
10-11 lumens per watt for incandescent bulbs 13-14 lumens per watt for halogen 50-60 lumens per watt for fluorescent
The lumen output of a GU10 bulb can vary depending on the specific bulb being used. On average, a GU10 bulb typically produces around 400-500 lumens. It's important to check the packaging or specifications of the specific GU10 bulb you are using to know its exact lumen output.

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.

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.
The lumen output of a 150W incandescent bulb is typically around 1600 lumens.
The lumen output of a 150W light bulb is typically around 2600 to 3000 lumens.
