Magnitude and Duration of Inrush on various lighting technologies

AI Thread Summary
The discussion focuses on finding information about the magnitude and duration of inrush currents for various lighting technologies. It highlights that inrush duration is influenced by the ambient temperature of light bulbs, with different temperature ranges affecting the duration significantly. Participants suggest searching Wikipedia for data on incandescent bulbs, while expressing a need for similar information on other lighting types, including LEDs. The conversation emphasizes the importance of understanding inrush characteristics for different lighting technologies. Additional sources for comprehensive data on this topic are requested.

Hi:

I'm wondering where I can find a table with the magnitude and duration of inrush on the many various lighting technologies at the various levels they come in.

Any suggestions?

Thanks!

OK I'll make the question more generalized.

We know the duration of inrush is relative to ambient temperature of a light bulb.

From room temp to Tmax will be something.
And from zero deg to Tmax will be more.

But are we talking about 20ms, 200ms, 20s, etc?

Anyone have a clue for any type of light bulb?

Thanks!

That should give you a ballpark idea for incandescent bulbs. I'm no help on the other lighting technologies -- well, except for LEDs :-p

Thank you Berkeman. That is very useful information. If anyone knows any sources for other lighting technologies that would help as well. Thanks again.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
