These types of lamps are probably very rare. Do you have a picture of the type of lamp?

It needs a 24 volt lamp, but with what amp? Do you think it is suitable if a normal lamp is installed for night movement? Has anyone ever tried it?

208 amps the total power of the lamp is 5 kW and you divide it by 24 volts and you get 208 amperes.

No will do.

Markings on the lamp 27V-200BT clearly indicate the voltage (27B = 27V DC) and the power of the lamp (200BT = 200 Watt). 200 Watts are more in line with the overall construction of the lamp, as 5 kW would surely melt the reflector and the lamp, as well as drain the batteries quit rapidly. Real current at 27V DC source is 200/27=7,4 A. Actual current and power is determined by the voltage of the power source as the lamp itself is of incandescent type.

If the correct lamp cannot be found, a substitute could be and incandescent libht bulb designed for 24V of up to 200W of power.

The biggest chellenge is to have the right infrared filter in from of the lamp if the original is broken.

Upravo onako kako je @dark-bullet napisao.

Pomenuti IC far ni u ludilu ne može biti snage 5 KW. Najjači IC far koji je postavljen na neki tenk je onaj iz sistema Štora. Deklarisana potrošnja oba Štorina fara je 1 KW, što znači da je po faru oko 500 W. Kako bi far te snage mogao da funkcioniše, potrebni su i masivni hladnjaci, kakve i imaju IC farovi sistema Štora.


IC far je u svojoj osnovi običan far sa dodatkom IC filtra, koji propušta svetlost samo u IC spektru. Mora imati snažnu sijalicu, kako bi IC snop mogao da osvetljava na velikoj daljini, a to je potrebno zbog aktivne noćne nišanske ili osmatračke sprave. Kada mu se skine IC filter, postaje klasičan far.

Nisam hteo odmah da skačem na navod o 200A struje, ali je očito nekoga zaveo originalni ruski tekst o električnoj napravi snage 5 kW. 5 kW moja se spominje u tekstu je snaga tenkovskag alternatora, dakle snaga glavnog generatora električne struje za sve potrošače u tenku. Treba znati, naime, da baterije (akumulatori) ne služe napajanju naprava u tenku nego samo (tj. prevashodno) za start motora tenka u koliko motor nije moguće staviti u pogon korišćenjem komprimiranog zraka, što je glavni način puštanja motora tenka T-55 u pogon. Akumulatori mogu poslužiti jedino kao spremište električne energije za privremeno korišćenje, ali dugotrajno korišćenje ih prazni. Idealno je kada je struja punjenja akumulatora čim manja, a to znači da su akumulatori puni, dok sve uređaji u tenku dobivaju energiju iz pre spomenutog generatora (alternatora) jačine 5 kW. Ta snaga predstavlja maksimalnu snagu svih istovremeno uključenih potrošača električne energije u tenku, od svetala, običnih i infracrvenih, pretvarača, radio stanice, uređaja za komunikaciju među članovima posade, ali i svih ostalih uređaja sistema upravljanja vatrom, na kraju i električnog dela grejača motora u zimskim uslovima.

I did not know how power in watts the lamp  uses.  Always divides the voltage by watts or curent from the watts, while the voltages X amperage  are equal to the power

Someone uses a regular cell phone camera in order to get a image from  infra reflection.
Оr like the man in the video who uses various filters.

   Prebacio sam se u vezi struje. U stvari je navedena snaga u vatima.

Hello. Does anyone have a schematic of the tank's electricity?

   Tek sad sam uspeo da nađem rezervnu sijalicu IC fara tenka T-55. Izgleda da na prethodnoj slici nije bio taj far već neki slabiji, možda od vozača.

Takva se sijalica dade kupiti na ebayu. Obično se prodaju kao sijalice za ruske (sovjetske) filmske projektore.

   Bio sam ubeđen da je za IC far pošto je nađena u RAP-u iz T-55.

Ako je iz RAP-a T-55 onda verovatno i jeste sijalica glavnog IC fara, jer je to ujedno
i najveći reflektor na tenku. IC far i radi sa "običnom" sijalicom kojoj se jedino vidljivo
svetlo zamaskira odgovarajućim IC filterom. Pretpostavljam, da rusi nisu radili posebne
sijalice samo za T-55 tenk nego je bila korišćena postojeća sijalica odgovarajućeg
napona i snage.

Ona snage 200w je onda očito od vozača, tj. IC far za vožnju.
