Refinement of energy-saving LED lamp

We have on sale lamps with pins and with an e-27 socket.
The price with pins 130r and 195r and with a base 250-300r and 500-550r.
I decided why should I overpay for each light bulb from 120 to 350 rubles.
If the socles can be taken free of charge as much as you want from burnt out lamps.
See technology here.
Here are the lamps left 195r right 130r.
Solder to the wiring pins, just need a good flux. I use phosphoric acid.
Wearing shrink.
Now we separate the cap from the bulb bulb carefully so as not to cut yourself.
We prepare the base.
Solder the wires from the lamp to the base.
We check the lamps for operability.
Since the lamps do not heat up to connect the lamp to the base, I use the usual gypsum putty in particular (VOLMA finish) remaining after the repair.
You can try silicone sealant.
That's what it turns out
It may not be very aesthetically pleasing, but just economically convenient and practical.
Thanks for your attention.
