Generally the lumen output of bulbs is proportional to the power used, if the bulbs are operated at their rated voltage.

What is the lumen output of a 60W incandescent bulb?
The output of bulbs varies. A typical output of a 60W incandescent bulb is 680 lumens.
What is the lumen output of led lamps?
LED light output varies greatly from near-zero to a current maximum of about 400 lumen. It is important to note that the lumen output does not necessarily indicate the potential for a light source to illuminate a surface for the purposes of viewing that surface with the human eye; two lamps putting out 100 lumen may well look to be of different brightness and provide different levels of perceived illumination.
How did you determine if there had been a change in the brightness of the bulb?
You would have to measure the lumen output before and after to determine is there was a change. There are light meters that can do this. You need to be aware of any background or ambient light during such measurements.
What is the lumen output of a 70watt Metal Halide Recessed Down Light Since majority of the light output is through the reflector area in the Down Light you want to know the total reduction of light?
Typical LOR (lumen output ratio) of a reasonable MH downlight would be around 0.6 meaning that you get 60% of the lumen output of the lamp out of the fitting. Any manufacturer should be able to provide the LOR for a particular fitting
What is the lumen output of a GU10?
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.
How many lumens make 1 ANSI Lumens?
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.
What does A 170 lumen flashlight equal in a watt flashlight?
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.
How many lumen output in a 50 watt power led?
Typically power leds operate as 1-2 watt units. 50 watt is a little excessive for a single led: it would have to be an array. The light output that can be achieved in normal use appears to range from 80-120 lumen/watt, so I guess the answer would be something like 4000-6000 lumen!
What is the lumen output for a 100 watt fluorescent lamp?
10-11 lumens per watt for incandescent bulbs 13-14 lumens per watt for halogen 50-60 lumens per watt for fluorescent
What is a dimmer?
A dimmer reduces the voltage to a light so that the current is reduced, which causes the bulb to have a reduced lumen output.
What is the lumen output for a 52 Watt halogen bulb?
Should be about 850 lumens. The same brightness is produced by a 15 watt CFL.
How do you change the word lumina from plural to singular?
The singular form of "lumina" is "lumen."
