How many of you still use small incandescent lamps?

    I was wondering if they are still used to make small circuits or if it is all LEDs now.

    At least they are still sold.

    And of course, these notorious 15W fridge bulbs...

    Yes...they make great current regulators in things like Wien Bridge oscillators.

    At last, a use for all those old flashlight bulbs. :p

    But seriously,
    It's easier to list the incandescent bulbs. One in the refrigerator, two (dimable) in each bedroom, both porch lights will be replaced with curly fluorescents the next time they burn out. Everything else is already fluorescent, either 4 foot tubes or curly bulbs.

    I have a box of about 1000 in many different sizes. Some old 6-volt automotive bulbs and many different indicator bulbs and flashlight bulbs of all types. Mini-neons too.

    Anybody need some, I doubt it. LED is all about power efficiency and heat management. The incandescent a are good for heater circuits and temp control. Weinbridge need small (micro-bulbs for higher frequencies).

    Why do you ask, Takao?

    The using life of 2W small incandescent lamps didn't long again, because the maker make it shorter, although I still used it, but I bought some AC110V 2W led to try,if they are ok, maybe I will try them more.

    I would like someday to replace the Christms tree lights in the AM Legion beer can flag with LEDs, but need viewing angle around 270 deg.. Of the 247 bulbs, about 30 had to be replaced since installing in 2004 & a spare set + some spares are in storage, so it probably will not be my problem.

    All the external lights on my car (10 years old) and wife's car (2 years old) are incandescents.

    Yes indeed, LEDs do not yet perform well in ovens.

    Likely very little (if any) energy savings to use an LED in an electric oven. All heat from the incandescent is going to keep the oven warm.

    They also provide overload protection for loudspeakers.

    You can still get flashlight bulbs?!!!

    Over about the last couple of years or so - I've asked at some point or other in every shop I've seen selling flashlights.

    About the only place I know of is the bicycle shop in the next town, they carry a limited stock of bulbs for previously popular bicycle lights.

    In the past not very long, most shops have dropped filament bulb flashlights altogether in favour of LED types.

    We'll, I must admit it's been several decades, but I'd like to try again to make some giant retro 7 segment incandescent displays. Something about strips of incandescent lamps making up a 7 segment display is good looking.

    If you don't need *HUGE* - they used to make little florescent indicators a couple of Cm long and a few mm wide, ideal for digit segments - might've been DM71 or something like that.

    If you *DO* want huge - 6" florescent tubes like they use in camping lanterns.

    ...or even 6ft tubes :D.

    I don't buy things....I have them. :)
    I have piles of small incandescant lamps....I just need to rummage through them all and see if any are priceless. :)

    I really am going to use incandescent. Reminiscent of the large panels of incandescent bulbs, showing the contents of the major registers.

    I find them fascinating somehow, especially the small ones. There are really green neon bulbs with a phospor coating (but of course no incandescent as such). Fridge bulbs hahaha, yes, I want to see if I still have these small To92 TRIACs somewhere.

    And make oscillators with neon lamps maybe.

    I bought some LED string lights too, they are more conveninent, dont cost much and run from 2xAA batteries.

    Must be bad times for manufacturers of small E10 Incandescent lamps?

    I remember playing with these, actually it was the first electric circuit I tried, using a 4.5v battery, and a screw socket.

    I mean they are interesting as a curiosity, not that I'd want to use them instead of LEDs.

    So I bougt 2 UK plugs, 2 fridge bulbs, both from a Euro store, I have some cables again...
    I even bought pinheads, blue tack and staples- want to try to make a motor similar to these I saw on youtube (with Neodymium magnets).

    Yes I got some pretty old bulbs here (see photo), even a few screw sockets.

    Somewhere under my desk is a tub of various bulbs collected over many years - its been a few years since I bothered digging it out to see what's in it.
