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! :)

Luminous means it emits light e.g the sun Non-luminous means that it does not emit light but can reflect light though.     Depending on which part of the flashlight you are referring to around 20% of the flashlight is both and the extra 80% is non-luminous. The bulb is the only luminous part but only when charged with electricity.              i hop this elps

How do you install 6V battery into Dorcy luminator


I was just having the same problem - I didn't realize that I had to take the black caps off the two springs at one end of the battery! Once I pulled those off, and put the battery in with the springs facing up, I was able to screw the top of the flashlight back on, and it worked. I hope this helps.

Tip

Prevent battery damage to flashlight


Any flashlight that uses non-rechargeable batteries, IE... AAA, AA, C, or D batteries. If it is not used on a regular basis and sits for a long time with the batteries still in it, the batteries will leak and damage the flashlight. It is recommended that if the flashlight is not going to be used for long periods of time, that you remove the batteries to avoid leakage into the flashlight. This also is recommended for anything that uses this type of battery. These types of batteries are known leakers.

Keeps blowing new bulbs


Since this is a simple construction flash light (no electronics) make sure you are installing the correct bulb for the voltage of the batteries.
If you use a bulb that is for a 2 cell (3.0 volt) in a flashlight that takes 4 cells (6.0 volt) the bulb will burn out every time.

We changed the battery pack and the bulb and it wont come on so the switch is prolly defective where do we find how to repair the flash light


Alot of maglites are problematic with symptoms like this... I have found that the culprit many times is the screw cap on the bottom of the flashlight.
The elecrtrical connection needed between the spring in the end cap, the threads on the cap and the threads in the barrel of the flashlight...
Make sure you twist your spring a bit..the dissimilar metals can actually corrode between the spring and the cap... Then spin the threads a little... Then try the flashlight again...
This procedure may save yourself replacing a switch..

Just a science project for a 14 yr old a simple emergency frequency scanner. Is there a kit or something?


Nothing that Ive seen for a scanner, probably too advanced for a 14yo. Usually an AM/FM radio or other type solar kits, try this link. I'.m sure you'll find somehting interesting. I remember when I was 14, we couldn;t afford these types of things and I would have loved to have had them. Good luck on the project. You can also Google solar powered kits to see if anything else comes up, I'm sure their are 100's if not 1000's of kits out there.

Charger is putting out 13.7 volts but battery does not take a charge


If its the right charger, and connected correctly, then it is probably just time to replace the battery. Try checking out http://www.batteryinternational.com/flashlight-batteries-streamlite---maglite.html for a replacement flashlight battery. Also, I'm not sure exactly what you mean by saying the charger is putting out 13.7 volts, but make sure you aren't using a charger that is too powerful, that can destroy the battery. Check out http://www.batteryinternational.com/battery-chargers-6-volt-battery-chargers.html. You shouldn't use a charger any larger than that. Hope that helps
