Intro: Emergency Bugout High Beam Flashlight
An emergency high beam flashlight can be simply constructed using a 3/4"x1/2" schedule 40 coupling and a GE or Cree 'Luminaria' recessed LED bulb 12 volt non-dimmable. I purchased my bulb in the bargain aisle at Wal-Mart for $3.00. The fitting was $ .40 at Ace.
A hot met glue gun is all that is needed to assemble the flashlight by hot gluing the bulb to the 1/2 " end of the coupling. Be sure that the bulb seats into the coupling tightly before starting to glue the two together.
Step 2: Gluing the LED Bulb to the Coupling
I placed the prong end inside the coupling on the 1/2" end and then hot glued the two together. I used a large bead to keep the two from separating.
Step 3: Adding the 9 Volt Battery to the Flashlight
Here is the 3/4" end upright and the 9 volt battery. Noticing how the prongs are facing I aligned the battery to line up with the prongs. The polarity doesn't seem to matter as the flashlight worked both ways. It is a tight fit and that is good so you don't have to worry about the light going out if a monster grabs you.
Step 4: Voila, the Mated Battery in Coupling With LED
These two are joined but I have not pushed the battery completely in to the prongs making contact. This is how it is stored when not in use.
Step 5: Shining Brightly Better Than Any Flashlight That I Currently Owned.
I would suspect that the range is 30-50 feet and it is a 'stage flood' type lighting. I used it to take my dog out in the morning before sunrise. I was impressed with the Lumens. By the way it is a "warm white" light LED. To turn off the flashlight by pulling the battery out just a little from the prongs contact.
NOTE: If the bulb prongs don't seem to reach the battery terminals because you used too much glue fold up two small squares of aluminum foil and pack each one on the outside of each prong against the coupling's wall. This will raise the 'prongs reach' a little so that contact can be made with the battery terminals.
