I remember they used these in stores and schools because they're easy to replace. The 2 pin have to be twisted and of course if you don't get them in properly, they fall out and break. Very cool I didn't know about the dots and lines being date codes. Thank you for sharing! 💡💡💡💡

Thank you for watching! I agree a lot with you! Honestly, although I really enjoy preheat fixtures, on a more practical basis, SlimLine are really easy to replace, maintain and, unless turned on/off frequently, they could last a very long time! (and without flickering at the start that sometimes can be frustrating or even dangerous!). In Mexico, they were almost everywhere before LED, but I'm wondering why the rest of the world preferred the two pin bases that were harder to clamp the bulb into, maintain and replace: as you said, when wrongly installing a lamp it could result on the lamp getting lose and falling off by itself, or just the pins stopping to make contact with the base terminals. On the other hand, on single pin (and also special bases for HO/VHO lamps), unless the fixture is poorly made, the bulb always fit and can run on every direction! Anyway, hope you learned something new on this video and see you in the next one!

Nice lamps! The 4-foot T12 slimline lamps were not very common in the US. The 8-foot was the most common slimline lamp. In grocery stores back in the 1960’s through 1980’s, they used to have continuous rows of two-lamp 8-foot slimline lamps. They would usually use a 4-foot two-lamp fixture at one end of a row if an 8-foot fixture would not fit. The workhorse fluorescent lamp in the US during the 1960’s through 1980’s was the F40T12 rapid start lamp. The full 40-watt F40T12 would also work on a preheat ballast. The energy saver F40T12 lamps which were usually 34 or 35 watts each were only usable on rapid start ballasts. Starting in the mid 1990’s, the F32T8 lamp on instant start ballasts became the workhorse lamp. Later on they also used programmed start ballasts for the F32T8 lamps that soft started the lamps and increased the life of the lamp, and were also used in fixtures controlled by occupancy sensors. It’s so sad fluorescent lighting is/has been banned in the US and other countries.

Beautiful lamps. I find it interesting getting a peak at what lamps other countries use. Here in the US 4 foot T12 slimlines are very uncommon. 8 foot T12 was the most common slimline in the US, being the industry standard for decades until the mid to late 1990s in department stores, grocery stores and similar public facilities, when T8 along with electronic ballasts began to take over, much like LED's in the 2010s.

I like the way flourecent lights turn on especialy the preheat ones

[@THEBULBHOME]

Me too!

Nice tubes! I used to have four of these in the F24 Variant, made in 1980 at the pilot plant. I gave two to another collector and unfortunately another one burned out so I am left with one. I do however have it lit up in a custom made fixture with a newer F24T12 daylight lamp. I have plans to eventually cut up an F40 Strip light to run some F48 lamps that i also plan on getting.

I really like those bulbs. My favorite when I was a kid. It's a bummer flouresant bulbs are not being used as much now. I still notice many still in service still though.

[@THEBULBHOME]

My favorites as well, and although they are been replaced with cheap and bad quality LED all over the world, at least my room with keep the T12 dynasty well into a couple of decades ahead!

WOWW

[@THEBULBHOME]

;)

[@generalstuffTR]

I prefer to use mechanic ballast i love flickering sound

[@Mr-Union_Sovietica]

Do you know why my lamp turned off and started to smell weird?

[@Placeholder71]

Are these cold-cathode?

[@ALT-9167]

I think th one thats swirling at the end is broken (the electrode ).

[@THEBULBHOME]

Noup, as they are running off an electronic ballast, if the electrode were to be broken, the lamp end would start to burn just like in this video: kzbin.info/www/bejne/q2XHf6KijrNjhqs as the ballast start to run the bulb in cold cathode mode! I think the swirling is caused by the cold start and uneven mercury displacement!

[@georgerdz5463]

Son de colección ya no se ven lámparas con ese tipo de casquillos circulares GE

[@THEBULBHOME]

Así es, mi buen Jorge, por eso me gasté unos buenos 3,500MXN en ellos 😅
