Camera Neons

[Andybiker]

About a decade ago I used the *TINY* neons from disposable cameras to make a fake 'colon' tube - it worked really well.

Now years later I cannot find any, all new disposable cameras use an led. Does anyone know where I can buy some?

These neons were about 3 mm in diameter and about 4mm long. I cannot find any this small. The odd thing about them was they needed about 200+v to light.

Despite these being in a cheap disposable camera the neons are still perfectly clear after all the years. Does anyone have a source?

Cheers,

Andrew

It'll be extremely difficult to find a disposable camera with a neon lamp instead of an LED these days, but if you search on eBay you can find a lot of small neon lamps (usually NOS). Here's what I was able to find after searching for "miniature neon bulb".

A few more.

But nothing really that small.

 That 200v strike was probably something special order just for use in flash circuits to let  the user know the cap was charged.

I knew I'd seen these somewhere - disposable camera boards:

Also available singly, plus they have another type on there - I put
'disposable camera' into the site search.

They were also used to prevent the cap from overcharging. I wonder how
this is done in the cameras that use an LED indicator.

Probably a limiter in the circuit, which also is gentler on the battery.

Maybe these small neons? Left in the picture - a "standard" neon is on the right for comparison. The grid on the paper is 5mm, 0.2 inches.

These are Chicago Miniature Lamp, part number A1B, Mouser part number 606-A1B.
