Jupiter is not luminous in that it emits light, it reflects the Suns light so that it is visible to us on Earth. See also Albedo.
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).

luminous
Giving off light, as a light source. The sun, a light bulb, and a candle are all luminous. The moon is not because it does not give off its own light but reflects it from the sun; it is illuminated.
A flashlight can be both luminous and non-luminous at the same time if it is turned on in a well-lit room. The flashlight itself emits light (luminous) while the ambient light in the room also contributes to the overall illumination (non-luminous).
A flashlight is luminous when it is turned on and emitting light. It is non-luminous when it is turned off and not emitting any light. So, a flashlight can be both luminous and non-luminous at different times depending on its operational state.
infra red maybe??? get a remote and your camera phone and you'll see what i mean or A flshlight can be non-luminous because the batteries from the flashlight gives the energy that makes light.
Light from the flashlight reflects off the ball to your eye which enables you to see the ball.
A flashlight is considered illuminated because it emits light due to an internal power source (battery). Luminous objects generate their own light without requiring an external source.
A flashlight can be luminous when turned on, emitting light from the bulb. It can be nonluminous when turned off because at that point it is not emitting any light.
It's non-luminous
At first light it DOES sound a bit confusing. First, the definition of the term 'NON-LUMINOUS'; 'Not capable of PRODUCING light but can be capable of REFLECTING light from another source'. For instance, our MOON is NON-LUMINOUS as it REFLECTS light from the Sun. The SUN is LUMINOUS as it produces light that is REFLECTED off the surface of the moon. And so, LUMINOUS means capable of PRODUCING light. Now closely examine your flashlight. The BATTERIES produce electrical energy which is transferred to the BULB which emits light, thus LUMINOUS. The tiny little BULB emits quite a lot of light for its small size. However, the bulb is contained within a concave silvered cone which REFLECTS,(NON-LUMINOUS) gathers and channels the emitted light from the BULB (LUMINOUS) into a BEAM which ILLUMINATES whatever you are pointing the flashlight at. Our cameras would be just paperweights if there were no NON-LUMINOUS surfaces for the light to REFLECT off of, back into the camera lens, onto the 'plate' thus etching the image. For example, take a photograph in the dark without the flash and what do you get. No LUMINOUS, no NON-LUMINOUS. And so there we have LUMINOUS and NON-LUMINOUS, ILLUMINATING our lives. Enjoy! :)
The two flames that flicker both non-luminous and luminous are a candle flame and a gas stove flame. When burning normally, these flames emit light due to combustion. However, if they are disturbed or lack sufficient oxygen, they can flicker and may become non-luminous.
A TV, when it's on and showing an image is luminous. When it's off, it's non luminous.
Luminous and non-luminous objects are both physical entities that occupy space and have mass. However, the key difference lies in their ability to emit light. Luminous objects, such as the sun or a light bulb, generate their own light, while non-luminous objects, like the moon or a book, reflect light from another source. Both types of objects play important roles in our understanding of physics and the natural world.
