Are LED light bulbs supposed to get hot?

Re: Are LED light bulbs supposed to get hot?

I think its the power supply that generates some heat . I think led bulbs create a very small amount of heat . Too hot to touch , some thing is not making good contact .

Re: Are LED light bulbs supposed to get hot?

I saw a documentary about the electrical grid and how it was long overdue for an upgrade. How when it was normally installed, it wasn't designed to last as long as it has lasted. Our electric in the states is better than other countries, but it definitely has problems. I just didn't realize we had issues like that in this area.

Thanks for pointing that out to me. I still have to test my meter though and I'll try doing that today. I've been busy doing other things. I ran one of the quad shielded RG6 coax cables from the baby's room to the basement. I want to run CAT 6 and CAT 3 6P6C, then I want to run it all again, but on the opposite side of the room. The opposite side of the room shouldn't be too hard, because I don't have to run it through the attic.

Our new stove came yesterday and I didn't get much work done. I hooked up the stove and had to wait for Corning Natural Gas to come and check and make sure there where no leaks and then remove their clamp. I was the only one home most of the day and unfortunately, I can't hear the doorbell upstairs, or in the attic, or in the basement. I just had to wait and they didn't come to later in the day. My wife's due date was two days ago but the baby hasn't come yet. We gotta go to the baby doctor today and they're going to talk about inducing her. We're leaving at 11:00 for that. We're definitely getting close though! Soon, I'll be a dad!!!!

I am glad to see that life is treating you well.

Re: Are LED light bulbs supposed to get hot?

In Florida I have seen the 120 V go as high as 150 volts. In Mississippi I have seen the results of the 120 volts going as low as 98 volts. I think it had to do with the load on the line and how many generators were on at a certain time. This was a while ago, but I do not think the electrical grid has been updated much since then.

Re: Are LED light bulbs supposed to get hot?

What? Really?? At our old place, always a steady 120V unless there was a brown out. Maybe in the city it's different though. Before, we lived out in the country.

Also, note the power company's voltage can fluctuate.

Re: Are LED light bulbs supposed to get hot?

I'm trying to think what was running when I was getting the 127VAC from each outlet. Now, they're all reading 122VAC.

We don't have too many heavy appliances that run off electric. The dryer is gas but it still needs juice. The washing machine is obviously electric. The microwave wasn't running....the dehumidifier was, the TV, the PC. Hrmm.

Re: Are LED light bulbs supposed to get hot?

Are you suggesting I install those permanently to my new panel when I install it? That'd be cool! Digital readouts!

that was my thinking.
you can also get ones that fit on a bus-bar with the breakers.

Re: Are LED light bulbs supposed to get hot?

All you have to do with 120 V outlets, for testing, is to check outlets for different voltages. Are you able to find an outlet that has a much lower voltage when a heavy appliance is going?

For example, on one outlet, you got a reading of 131 V and 111 V on another outlet.

a couple of meters on your next panel would be nice.

I have an analog multimeter around here somewheres. I haven't made friends with the neighbors yet. I'm going to find it and try measuring the voltage with that. The chances of them both being off I think are very slim. Although both might need calibration, if they do, I should get different readings from each meter. Not the same. Just gotta find what box it's in.

I've been running coax, cat6 and cat6 6P6C in the baby's room down to the basement. It's a bit of work and is taking longer than I expected. I only got the RG6 quad shielded stuff ran last night. But I think the rest should go easier.

'So, it's possible for the DC measuring parts of the multimeter circuit to be calibrated but the AC parts to be out of calibration? ' A big YES.

Re: Are LED light bulbs supposed to get hot?

Calibration of a meter has to be done on each range in increments from a low setting, middle setting and high setting in each range and make sure the readings are with-in tolerance. This is usually done with a calibrated programmable supply that cost $60,000 in 1987. It would have a sticker on the calibrated supply that is traceable to The National Bureau of Standards. This sticker has to be replaced every year.

I have a calibrated DC PSU with one of those traceable certificates. Now, you can get stuff calibrated without a traceable certificate but a lot of times, they're required, depending on where you work and what you do. My certificate has probably expired but the stuff I'm doing, I'm not gonna worry about it (the PSU I mean, not the meter).

So, it's possible for the DC measuring parts of the multimeter circuit to be calibrated but the AC parts to be out of calibration? I gotta get some sleep though, I'll be back tomorrow. Night.

Re: Are LED light bulbs supposed to get hot?

No, I should had been more clear. I meant all the outlet's are just 120VAC. I thought Stj was referring to the 240V outlet that I installed in the old house for my BGA rework station. You guys helped me wire it up. Sorry for the confusion.

Re: Are LED light bulbs supposed to get hot?

Just measure at the outlets, less chance of getting kill.

Re: Are LED light bulbs supposed to get hot?

Go to your neighbor house and take the AC reading of their outlets to see what you get on your meter.

Okay. But don't try reading the voltage coming into the house directly from the breaker box? I thought I could do something like this:

I thought maybe but the meter across those big main wires coming in as well. Is that a bad idea?

Re: Are LED light bulbs supposed to get hot?

Well, it sounds like you need to get good working meter to start with otherwise you are doing goose chase with the wrong data.
What do you mean you do not have 240VAC yet? I never seen the house that the Electric company does not provide split-phase power to the house.
Amperage of the panel has nothing to do with getting the split-phase power to the house or not.
Show us what you have in your breaker panel.

When I wake up tomorrow, I'll pull the cover off and take some pictures. Tomorrow is my wife's due date for the baby but we're not sure she's going to come tomorrow or not. I'm going to head to bed now so I can get up early, just in case.

I know amperage of the panel has nothing to do with getting the split-phase power to the house. I thought though maybe the setup isn't correct. One 100 amp panel that supplies a 60-amp smaller sub-panel....I thought perhaps the people who installed it didn't know what they were doing and maybe that's why we're getting some weird readings and have some unhooked wires in the basement, etc.

They said "updated" wiring. It was knob and tube, they replaced it. From what we can see (under the baby's subfloor, in the attic, the basement), it does appear to be removed (the knob and tube). There's some wires still there, they're just not hooked up anymore. I've questioned some of the previous owner's...repairs.

Some of their repairs were dangerous and could have killed us. Not sure how the house inspector missed some of that stuff. At one point, someone worked on the house and knew what they were doing. Then, at another time, someone worked on the house and didn't know what they were doing. Somethings are done proper, some things aren't done right at all.

Re: Are LED light bulbs supposed to get hot?

So your saying you only one 120 RMS power line coming into your home?

No, I should had been more clear. I meant all the outlet's are just 120VAC. I thought Stj was referring to the 240V outlet that I installed in the old house for my BGA rework station. You guys helped me wire it up. Sorry for the confusion.

I meant I do not have any 240VAC outlets yet. My old house, we had a 240V outlet for the stove, a 240V outlet for the dryer, and a 240V outlet for my rework station, that I wired myself. I just meant all the outlets in this house are 120VAC outlets.

I'll try new batteries for the meter. Is there any good ways of testing the meter? Testing with DC shouldn't be a problem. I can just set my calibrated PSU to a voltage and test to see if the meter measures it accurately.

It's a Craftsman Professional 82357. There's a sicker on the back that says:
82357
242.82357.0
Sears, Roebuck and Co.

It's a true RMS meter. A long time ago, I found a digital copy of the manual on Sears' parts webpage, but I don't think it exists anymore. It'd suck if this meter needed replacing. We've fixed sooooo much stuff over the years. My parents bought it for me as a gift when I was child, hoping I'd get into electronics and everything.
