Blue neon bulbs (brand new)
These 2 blue neon bulbs come from the bag of neon bulb samples I received from my mom's friend in around 2010. Recently I walked through a number of hardware stores and none of them sell blue bulbs, but only amber bulbs.
These bulbs are powered without a ballast resistor in this demo. To use these bulbs properly, always connect a ballast resistor.
Warning: High voltage is applied to power these neon bulbs. If you are going to play around with these bulbs or any other high voltage components, safety precautions must be taken or you may have a risk of electric shock.

E9 4.8V clear spotlight incandescent bulbs
มุมมอง 146วันที่ผ่านมา
These spotlight bulbs have a lens at the top to focus the light of filament, in order to largely increase the output, making it ideal for handheld torches. The rating of these bulbs is 4.8V 500mA. One of them is came from the handheld lamp in this video, while the rest are from a hardware store I cannot remember.

E9 6.3V clear tubular incandescent bulbs
มุมมอง 43314 วันที่ผ่านมา
These two bulbs are bought from a hardware store I cannot remember in 2008. These bulbs are supposed to be used as panel indicator lamps so they do not appear to be very bright, even powered by 4 alkaline cells (giving out 6 volts). The rating of these bulbs is 6.3V 250mA.
Amber neon bulb (brand new)
มุมมอง 63421 วันที่ผ่านมา
I received a bag of neon bulb samples from my mom's friend in around 2010, who is used to work in an electronic components company. This bag of samples contained 4 amber bulbs and 2 blue bulbs; 2 of the amber bulbs are used to replace bad bulbs in power strips, the other one is lost and this is the only amber bulb that still free. This bulb is powered without a ballast resistor in this demo. To...

This 4W fluorescent lantern is bought in 2007, having 6V 600mA rating, which can be powered by either a regulated plugpack or 4 AA batteries. This lantern also accept rechargable cells, by sliding the switch towards right the lantern will start charging the cells and the red LED indicator will turn on. The battery tags have been corroded due to leakage of alkaline cells in past and their electr...
E9 4.8V clear spherical incandescent bulbs
มุมมอง 1.7K28 วันที่ผ่านมา
One of these bulbs is came from this handheld incandescent lantern, while the others are bought from a hardware store I cannot remember before 2010. In this video they are powered by 4 NiMH rechargable cells, which give out 4.8 volts. The rating of these bulbs is 4.8V 500mA, but capable to run up to 6.5 volts. Besides they feature white paint at the base, the filament also gives a high output.

An unstable neon bulb
มุมมอง 588หลายเดือนก่อน
One of those 22 neon bulbs has been darkened and it behaves differently when turned on. This video shows how the distance of my fingers and the camera from the bulb affect its behavior. Warning: High voltage is required to power on a neon bulb. If you are going to play around with these bulbs, safety precautions must be taken or you might have a risk of electric shock.

Just like most of the other fixtures, the ballast of this fixture is also program start while one side of the electrodes would attempt to ignite during warm up stage.
E9 2.5V clear spherical incandescent bulbs
มุมมอง 302หลายเดือนก่อน
These bulbs came from some integrated science experiment kits for primary education bought in around 2001 to 2003, having a rating of 2.5V 300mA. Those kits also came with some bulb sockets, AA battery cases and wires for children's self-learning purpose. This is the last video that introduces regular low voltage (below 4.5 volts) screw mount mini bulbs.
Lamps with failed backup battery
มุมมอง 595หลายเดือนก่อน
These two fluorescent fixtures failed the power outage test because of the failed backup battery. They keep flickering for around 10 minutes until the battery exhausted. When the power supply resumes, they turn on normally. If the battery is good and charged, the lamp will glow when the power supply is out, but dimmer than usual.
Self ballasted amber neon bulbs
มุมมอง 517หลายเดือนก่อน
These amber neon bulbs are salvaged from 4 broken power strips. The bulbs are used to install at the on-off switch of each output socket as indicator. There are 22 bulbs, each of them have a 220kohm series resistor. 18 of them are in good condition, in this video I picked two of them to test. The light is always stay at the top of the electrode rods. Warning: High voltage is applied to power up...
Failed FIAM T5 4W fluorescent tube: revisiting
มุมมอง 504หลายเดือนก่อน
This failed FIAM fluorescent tube has been put aside for more than a year after the last test, lets power it up again to see if anything different. Different from all other 4 watts fluorescent tubes I used to have, the color temperature of this bulb is 4000K, but unfortunately this is also the only bulb that fails without reaching EOL.

Woooow😢
In your country people still seem to do a lot of maintenance on fluorescents, here people change to LED even the ones that are working...
Not at all, still like that you say. And the new LEDs go bad really quick due to cheap quality.
Very nice!
How this neon bulb didn't exploded and tripped the main circuit breaker, if you didn't operated it with a ballasting resistor?
It is not directly from the mains, but a fluorescent lantern.
I have this light and it relies solely on thermionic emission to start. I really it.
make a video on low pressure sodium
he doesnt even have a single flourescent light fixture, neither the low pressure sodium
@@fansloverz oh ok
@@fansloverz I do own some fluorescent fixtures, but literally a very small number and most of them have already shown off in previous videos. Please feel free to check out my uploads. Even I would collect some bulbs, but I am an electronics hobbist, not a bulb collector. I have built a number of projects, usually relate to lamp simulations and displays. But the viewers are not interested in those uploads so I no longer making those videos.
@@chihofung6860okay
This bad programmed start ballast😮
I just bought a fixture that takes 2 49w t5 fluorescent bulbs i didn't have the bulbs at the time so i bought some t5 49w bulbs from airam one of the two bulbs broke during shipping sadly so i have one now

Qi have one that is hardwired and uses a 5v iPhone charging adapter to power the light
You got yourself a new neon indicator bulb, neon indicator bulbs, mainly contain the neon gas, but they sometimes contain argon nitrogen, which makes UV light so they use phosphorus for those neon indicator bulbs, Swiss nitrogen argon, gas Foster glow, blue and green so you have a red standard neon indicator bulb and two argon nitrogen ones with blue and green phosphorus
Is this the fixture you use for those neon bulbs
Yes it is.
@@chihofung6860 cool

U finally show the actual looks of flashlight
End of life?
I rram am yuiioi and I’m a bit 0:16
How's it bad? I don't see a burnt end and no flickering
The right side of the bulb glows pink and dim, which is not a normal bulb that supposed to.
Qui in italia ci sono dei supermercati che hanno una grande batteria in comune e un po di lampade attaccate con un reattore elettronico che lavora 230v sia in corrente alternata che in vorrente continua
Siii io ho una plafoniera 4x18w e ho 2 reattori da 36w però una cosa molto interessante che ho trovato è un inverter credo sia per neon che converte la corrente della batteria per i reattori
but is the battery pack the same for all the lamps or is there a battery in each lamp?
One battery pack for one lamp, used as emergency lights. Not every lamp has the battery installed.
Does this fixture use a capacitive ballast? I made one with capacitive ballast and the lamp also lasted about 5 weeks like one of yours that you showed in another video, but I don't know if this is due to the circuit being somehow inadequate or the tube being of low quality
Just a regular electronic ballast with glow bottle starter. I tried this lamp in other fixtures and it still failed to start.
@@chihofung6860 electronic with starter? but does it have a rectifier or something like that?
This fluorescent eol. But ballast not auto shutdown power off !
I can want change programmed start ballast start up😅
Preheat start magnetic ballast
This fluorescent ballast feel best, eol. fluorescent can auto shutdown power off ! Very good ballast !!! This ballast is programmed start type?
This is programmed start with EOL lamp detection.
This new fluorescent is mercury lose
I don't understand how that happens.
