Going down into the underground "catacombs" of his work, very often it is necessary to use lights of different formats. In our cellars of the normal lighting can only dream of, the management company does not plan to cash expenditures for such "trifles" as a comfortable access to communication. Once in the basement, neither of which is not visible, because of the poor lighting means everything is "normal".
Therefore, for the time of his seniority, Plumbing, I changed a lot of lights. from bulky miners' lamps and ending with a compact LED technology.
At work, at the moment I use LED lamp with power supply 18650 elements. He used his usual waterproof divers. Moisture protection is not often, but it comes in handy when you have to crawl under a stream of water in a dark room. Link to your torch will leave at the end of the article.
At work, we have long lie volumetric lights of dead batteries, but with a working filling. One machine I managed to scrounge unnecessarily them long ago written off.
The idea is that it is necessary to replace the battery in the lead, but again he did not last for a long time and die. So I will replace lead acid battery for 4 volt cells nickel-cadmium batteries of the new screwdriver KOLNER. This new Shura for 1000 rubles I had to review. It had to be rejected. A link to a review at the end of the article.
First of all share three pieces of the cell (Photo1)In which the voltage is 4.5 volts. The resulting parallel circuit 2 are brazed
(Soldering) and wrap tape (Photo 2)In order to avoid "short stacks". Intended charger (Photo 3) a spotlight housing, has at the output a voltage of 5 volts, which is sufficient to fully charge the battery cell. Continue to strengthen our battery pack in the housing and solder the leads(Photo 4).
Putting housing of our lamp and conducting tests
Within an hour, while he was in the garage, I was not able to land batteries, even brightness is not diminished. Typically, this flashlight dies on lead BATTERY 20-30 minutes of work. Well, here progress. I am satisfied, will I still have a flashlight in the wings.
