Thread: Household light globes

Hi , you can series or parallel them to get the load you need.
Cheers

I still have some incandescents around the house, in lights that only get turned on once or twice a year, or never.

If you're stuck let me know, and I'll see what they are, and can send some your way.

I buy all mine at Bunnings. Osram for the halogen replacements and Philips appliance bulbs down to about 15W.

Can't you make up something with an LED and a series of switchable resistors of appropriate value, to make one device with multiple test abilities.

No, a dim bulb tester relies on the light bulb being a “non ohmic” resistance. It’s precisely the non linear response of a filament that makes it work, so resistors are no substitute.

Yep, similar legislation to Australia was reversed around 2008ish if i recall with a change of govt. I quickly made a hotbox with incandescents to assist some vinyl ester resin mouldings to cure in the middle of a wet cold winter about 10-12 years ago. I then used them to keep some native orphan ducklings warm till fledged. Don't know what haapened to them after that. 2.5W LEDs prevail in our house these days.

Ducklings are going to freeze.

I dunno. I am maybe getting old, but I hate the light from LEDs. Sure, you can get much better ones, warmer, these days, but my eyes don't like them. Better though than the CFLs a certain polly wanted us to all have.

Anyway, none of them are fit for my purpose. Clear or pearl. 30, 60, 75 or 100watt. Bayonet preferable, as I have the sockets.... sigh.

if your dull bulb tester works like I think it does, you can also use nichrome wire and old school carbon heater elements.


The nice thing about using the nichrome wire is its easy to position the wire mounts to account for the varying required wattages then clip your load onto the required point.
