Perm pensioner invented and patented an anti-vandal eternal light bulb

On my account there are more than a dozen different inventions for the garden, vegetable garden, repair and construction. But I don't need fame, I just want to tell people how you can save money and manage your household wisely.

Vladimir Alexandrovich Stepanov, retired inventor.

After retiring, Soviet engineer Vladimir Stepanov directed his energy in a useful direction: he became the head of the entrance and began to fight for cleanliness, safety and durability.

One of his patented inventions is an anti-vandal light bulb, which he installed in his own entrance.

The device consists of:

• LED bulbs with a power of 3 or 5 watts.
  Incandescent / halogen lamp will not work due to heat.
• connecting connector;
• neck from a plastic bottle;
• gypsum;
• steel wire.

We install the cartridge and the lamp into the body from the neck of a plastic bottle, and fix it around with steel wire. To prevent the cartridge from dangling in the neck, fill the bottom with plaster mortar.

After the gypsum has dried, the structure is ready for installation inside the wall. Thanks to the protective wire casing, the lamp cannot be broken, and the fact that the LED lamp makes it completely eternal.
