Ever since I started mining, I noticed that many lightbulbs started burning out faster. This was on the breakers which shared the outlets with the miners and the light switch.

This wasn't a problem last year where in Canada the 60W incandescent light bulbs were still legal and cost about 10 cents each. Now going to Home Depot and the absolute cheapest light bulbs are the CCFL and they cost about $3 each. Also the "flood light" type bulbs are expensive also at about $4 each.

I noticed that this is due to

"Abandoning stale searches to restart"

this happens every few minutes where the miner shut off mining for a second and then restarts.


Was wondering is there anyway to prevent this from happening? Maybe doing shared mining between 2 pools?

install a surge suppressor between you miners and the wall outlet it stops power "noise" from traveling both directions.  Not a $10 power strip, but a real surge suppressor.

what version of softwre miner are using if bfg


try to put  


BFGMiner:
stratum+tcp://pool url.com:port_num/#xnsub   (mind the slash '/' before #xnsub) all version of BFG beyond 4.7 support it


CGMIiner may or may not .

one version might not, one may

but with cgminer use it the same but no / is needed

CGMINER:
stratum+tcp://poolurl:port_num#xnsub (no slash '/' before #xnsub)

if your version of CG doesn't support it, if CGMINER IS the software you have, it just won't work


that should help stop the discount if your not doing it all ready . You are anlt coin mining the way it sounds ? .

On my Jupiters I am running bfgminer version 3.8.1
On my S2 I am running CGminer version 3.12.0
S3 running an unknown version.

I am not mining altcoins just F2Pool.

Move miners to a different breaker(circuit).....

not an option.

try it any way it helps with any disconnect i remember one time  i rented a miner the guy was having disconnect issue, i was only doing one coin with that miner, I asked him to try that it worked , his DC stopped but it may be a power issue you power is dirty so to speak or keeps dropping due to power company issues, check there site to see if they are having any kind of issue some times the power company's are and report it on there site . or get a new surge protector I'm  sure you have one now with all that gear. make sure the PSU or PSU's are ok .


NM #xnsub won't just noticed your versions of  bfg try to update it to  5.4.1 maybe then try ? . i really can't say what version of CGMINer other then start with cgminer4.8.0 on i think they put in support then but took it out at the latest CG MINER or it's there but you have to patch it in .


BFG has a nice walk thu in the ASIC read me on how to update the Jupiter or Neptune to the last version .

one other thing you might try is buy one of the higher end lightbulbs if the surge protector doesn't work, it may just be cheap lightbulbs, i know you don't want to hear that but it could be that sadly .some of those low enrgry  lightbulbs are made cheap and burn out faster then the more costly ones. but try the surge protector first if it keeps blowing, it might just be cheap made lightbulbs :P(.

The other solution is underclocking/undervolting your miners so they dont put such a large power draw on that circuit.

OP how much watts are you putting on each circuit? Also what volt and amp are the circuit breakers?   I just have never had issues with light bulbs makes me wonder if your pushing wiring or breaker really hard.

Have you tried anything new like the LED lightbulbs? Might be worth a shot trying one and see how it does compared to the CCFL if they keep dying.

Yeah, I remember when I had my 15A / 120v circuits at near full load, the lights(on same circuit) would brighten briefly during block changes. LOL! Ultimately I had to spread them out on different circuits ... so I didnt get "new block found on network" reminders. HAHA!

Its kinda like turning a hairdryer on and off ... those things easily put a circuit near max and the surge of current they pull when u start them is what causes dimming.

For everyone that replied.

I tried different brands of light bulbs. The cheap dollar store ones and Phillips/GE they all last the same amount.

I am pulling around only 1000Watts or so.

LED is very expensive and if mining kills those LEDs then its going to get very expensive.

Besides buying expensive surge protectors, is there any software method to fix this?

I just mentioned a software method.... lower the clocks / volts of the miners! Dont draw as much power.

It makes me wonder of quality of wiring or breaker.  I have pulled 1K + on multiple circuits in my house never once killed a bulb.  I now have most in my mining area, which is a nice option to have (I realize most don't have this option).

I'm suggesting trying 1 led bulb to see what it does.  I think it's possible it will act different as so low energy to power.  But I would not switch all to this unless you are sure it wont kill it, as your right it would make it more expensive.

Haha, yeah ... I know a circuit in my place is not wired right from a certain outlet forward or something. Basically the delta between ground and hot is 60v or w/e its not the perfect 120 -120 0 (or whatever they should be) it should be when measuring all 3 holes in relation to each other.

True, i had a 110 10/2 15 amp  line up to three k once it only popped when the dic washer kicked in sense that was the only thing besides my miner on it, sense then ive had 2 110 20 amps put in, then a  new main panel then a 240 30 amp on 8/2 wire, i use now.

sense he said it"s not a option to try another line i tired to help him with what he had.

nice glad some one pushed it,
it sounds like it his wiring at this point .
 but sense that's not a option, lower the speed as some one else said or try a different line.


those miner are pulling a 1000 watts can I  buy them :) at default speeds ?.


i guess my point is not being a jerk how do you have a s2 and Jupiter doing that that's amazing  il buy them more then one Jupiter ?.


does sound like they are pulling to much .

Who needs light anyway?  Running those bulbs is killing your mining potential!
It's cheesy but you could run a 12 gauge short extension cord from another room.

1) Surge protectors aren't that expensive and are a good investment. I'd just buy one, it might end up saving your gear one day and easily pay for itself by doing so.

2) Yep, totally. Run a 30' extension cord from another part of the house to a cheap lamp. That would be solution #2.

If you have to go cheap, do whatever is cheapest, but do something now. Eventually you'll spend more on bulbs than either solution.

Use one of these. It will even out the surging caused by the miners going on and off.

I put my miners on APC surgearrest ~$19.99 now, I bought in microcenter (more expensive), but here is an Amazon link:
http://www.amazon.com/APC-P8T3-SURGEARREST-SPLITTER-PROTECTION/dp/B0012YLTSA
walmart has it at $2 discount
http://www.walmart.com/ip/APC-8-Outlet-1750J-Surge-w-RJ11/12321687

useful thing anyway, 1750J surge protector (much more than 540J for a typical $8-10 beige one), 150K in equipment protection.
lamps are doing fine.

I suggested the same thing.  I think try one and see how it goes.  The LED use a very very small amount of electricity.  I don't see them being killed, but I would start with one just in case.

And if your electricity does kill a LED bulb honestly I would get a electrician.  It is not normal to kill lightbulbs with only pulling 1k watts on same circuit.  So having him/her look at the wiring and circuit breaker might be good if you do kill a LED.

either way i would, it shouldn't being doing it in first place unless hes overloading it, drawing to much , then he needs to balance it out. follow the wires some how make sure there not getting hot etc. feel the breaker if it's even warm there might be a problem.

  Are bulbs incandescent or CFL?  This will assume incandescent.  Bulb life expectancy is determined only by two electrical factors - hours of operation and voltage (temperature).  127 volts on 120 volt circuits means a bulb will burn out twice as fast.  A mining computer will only lower or leave unchanged voltage.  That will either increase or leave unchanged a bulb's life expectancy.

So, does bulb intensity change when computers power cycle?  Only that (and measured voltage) indicates anything electrical that affects bulb life expectancy.

A second mechanical factor applies.  If bulbs are powered when, for example, something falls on the above floor, then that vibration can harm a bulb's filament.

Nothing in software affects bulbs.  Bulb life expectancy only decreases when voltage increases.  Short term voltage increases are indicated by changing intensity.  Constantly too high voltage is identified by measuring either with a digital meter or a 'Kill A Watt'.

As others have suggested try out LEDs, used to have a dimming effect come into play with standard cheap bulbs but since switching over to LEDs I believe it is resolved, can't be 100% certain although I have not noticed any dimming for the past 4 months.

And the more I think about this one the more I wonder if something bigger is wrong.  It just is not normal to kill light bulbs because of 1k watt miner assuming decent wiring, and breaker is decent.  LED likely will be a fix... but I wonder underlining cause.

Honestly you might think about getting a electrician even if the LED fixes it.  I would ask them to check gauge of wire, make sure it still seems to be of ok quality and no issues.   Really open up the breaker box and look at what's behind the metal front (I dont suggest doing this on your own if not use to electricity and don't have power to house off.  The main can be a scary thing on amount of electricity).

You can run some things yourself like checking circuit - http://www.amazon.com/Sperry-Instruments-GFI6302-Outlet-Tester/dp/B000RUL2UU/ .  That  is kinda a DIY version a electrician will be much better on that. 

I don't think the LEDs will help because in one room I have those IKEA lights and they use a 35Watt halogen bulb and they flicker also during block changes.

Pretty sure nothing is wrong with the electrical. Its just in-rush current kind of like when starting a large motor or washing machine. 1000W is considered a pretty large load. Maybe a surge protector can suppress this.

110 or 120 though should be able to handle 1k watts pretty easily.   It is a lot of power but it should not be a game stopper unless you have a lot of other items or some high wattage items on same circuit.

But 1k watts is not horrible as far as load it should be able to handle it.

Have you tried measuring what voltage the loop with your light bulbs has ended up at? Also, LEDs? They'll have 5-20x the MTBF and likely actionable warranties.

Your circuits, if properly wired, should handle 1000 watts easily.  Otherwise even a clothes iron could not work.

A large inrush current does not cause a voltage increase (if wiring is correct).  It would cause a voltage reduction.  A voltage reduction means longer bulb life expectancy.  Your conclusion contradicts your observation.

Recommended was what you should do.  Since if that load creates a higher voltage, then you have a serious human safety problem.

LEDs would not address the reason for a high voltage that causes premature bulb failure.  A serious human safety issue might explain it.  Never fix a problem by ignoring the reason for that problem.  Always first understand a problem before solving it.  This one is so simple IF some a minute of labor results in some useful numbers.

Yes they are all around 121 Volts or so.

Voltage reduction for a split second won't increase the life of the light bulbs.

When there is a voltage reduction every few minutes or so, its like turning the light bulbs on and off. The on and off turning is what causes the filament to degrade and the life expectacy is decreased.

I am thinking that the voltage might be a little too high and that's what causes this issue. Aren't most places around 115Volts ?

  That is exactly what does not happen.  Power cycling does not harm any incandescent bulb.  Again, summarized from the industry 'bible' are the only things that reduce bulb life expectancy.

Bulbs changing intensity with a 1000 watt load suggests a wiring problem.  Critical is to identify intensity changes on that circuit AND on any other circuit.  Since in most cases, that wiring problem is only a nuisance.  But in some rare cases, it is a serious human safety issue.

AC voltage is 120 volts.  If voltage is constantly exceeding 127 volts, then bulbs are brighter and last only half as long.  But again, what is changing intensity and how (dimmer or brighter) are critically important facts.  Do not make conclusions based in speculation.  You do not know yet what is causing bulb failure.  Dimming would only increase bulb life expectancy (irrelevant if by a lot or a little). Dimming (and power cycling) does not shorten the life expectancy of any incandescent bulb.
 
Also discussed was damage due to vibration - such as someone walking across the upstairs floor.

Honestly it highly likely is my wiring / electrical setup, this house is very old and I don't think the electric systems have been looked at for a very long time.
