Depends on the flashlight, some have many bulbs which would probably shine brighter, or just one big bulb which depending on the bulb, might shine less bright.

How are a laser beam and a flashlight beam alike and different?
A LASER, or Light Amplification by Simulated Emission of Radiation, and is made by causing a particular substance to emit photons, almost all of which are one wavelength. A flashlight, however, uses a light bulb, which emits light due to the filaments, and will spread out. Both, however, are forms of light.
What does beams mean?
The phrase "laser beam" refers to the columnated light that is emitted by a Laser.
Does a flashlight emit amplitude or frequency modulation?
A flashlight simply emits light. The light contains no information other than to provide light so people can see where they are going.
How is laser light different from light emitted from a flashlight?
Laser light is different in many ways. These are the biggies. a) Laser light is almost monochromatic. Because it is created by exciting a specific substance to emit photons, the light emitted by the source is almost all one specific wavelength. The light from a flashlight contains all of the colors in the spectrum, forming "white light". b) Laser light is very coherent. This means that the waves leaving the laser remain in phase for a very long time. Light from a flashlight is not coherent. As a result, a laser can project a distinct beam of light much farther than a flashlight. c) Laser light is directional. This means that the beam of light being emitted does not spread much with distance. Hence it can still appear as a point of light many meters away from the source. A flashlight beam will quickly spread the further it is viewed from the source. Because of these fundamental properties, lasers are an excellent experimental device.
Why do pulsars beep?
Pulsars rotate like most stars. Pulsars also emit beams of energy which, if they cross our path are perceived as pulses of energy with a regular rate (ticks, beeps, etc). This is called the lighthouse effect. Picture a lighthouse -- the lighthouse itself is the pulsar, and the beam of light is like the pulsar's beam.
What is the purpose of the concave mirror behind the bulb in the flashlight?
You want a torch to emit light in a beam, in only one direction. But the bulb in the torch emits light in all directions, the mirror reflects the light going in the wrong direction(towards the inside of the torch) back out the front of the torch making it brighter. It is concave so as to focus the light more.
What is persistence in computer graphics?
persistence mean how long the electronic beam continue emit light after the CRTbeam is removed
Is a laser beam the straightest thing on earth?
Not nessacary. It can also be a fine stick, or a piece of wood. But it can be among the straightest. This is because a laser beam somewhere will emit light.
When the flashlight is turned on electrical energy is changed to which type of energy?
Heat to make the filament glow white hot and emit light (electromagnetic radiation).
Are rotating stars that emit directional beams of radio waves?
pulsars
Does using more than one magnet affect light on a flashlight?
Though I don't fully understand your question, I can assume you mean "Do magnets affect a flashlight" or more specifically, "light". No order of any magnets can bend a light beam. Gravity, on the other hand does, as light (photons) behaves both like waves and matter. However, it would take a huge amount of other matter to even detect any bend in light. In fact, large imploded (dead) stars, having masive concentrated mass and thus gravitational pull, in effect, cause a "black hole"; a visual area in space in which no light appears to emit from behind it. So the simple answer is no, no number of magnets will affect the light from a flashlight.
Is an eye luminous?
No. Eyes are not luminous. They observe or perceive light but they do not emit light. Luminous means "emit light." There are various species of animals, such as deer, cats, and dogs, whose eyes have the ability to reflect light which sometimes make them appear to glow in the dark as they reflect a flashlight, headlight, or other light that is shining in their direction. But even then, the eyes do not produce their own light so they are not luminous.
