What bulbs are what, and how to tell?

[ericmark]

Is it a failed standard bulb, or a smart bulb turned off. Reasonably sure this one is a failed bulb, as in the main watts x 100 for a smart bulb is more than the lumen, but for a standard bulb it is normally less than the lumen, so this one going in the bin.

Replacement 806 lumen and 6.5 watts, filament type, it says less lumen as the bulb it replaced, but seems to light the room far better, giving off an all round light. And a clear glass bulb, not frosted plastic. If made Jan 2019 not done too bad. Google does not help.

But this bulb is B22d, so the number tells one nothing. Add make and yes

That seems to be the bulb, and not smart type, but don't want to hunt every time a bulb fails to find out if failed or simply turned off in the bulb.

Mark smart bulbs before you fit them ?

I think in future I will, I could remember to begin with, but 4 years down the line, I can't remember what I fitted.

I find you just have to try the bulbs.
6000k bright white not the yellow colour we prefer.
800 lumins
Watts don't mean anything although our bulb is 6.5 watts.

If bulb is enclosed then you need to check spec as some bulbs aren't suitable as they get too hot and won't last.

This guy takes loads apart if you are interested.

I found the plate was far simpler, but failed to open it further to find what was under the heat sink.
I assume there must be a capacitor and rectifier under the aluminium plate, but it clearly was not a smart version.

This however, this was a smart lamp and far more complex.

You surely must know whether or not you're using it as a 'smart' bulb?

Hang on... you think 6 years is not bad?

I think 6 years is terrible for a conventional bulb and everyone keeps telling me how much longer LEDs last.

I had to replace 60 W incandescent bulbs in my lounge every year (facing north, so I have to turn the light on fairly early in winter). They were guaranteed 1000 hours, which is an average of less than three hours per day.

If they're smart, can you not simply use the app to try turning them back on, and if they don't, assume they're knackered?

Surely what bulb it is now has no bearing on what bulb you fit next; what bulb you fit next is driven by what facility you need at that location?

Why not nip round all the working bulbs now with the app, influence them smartly and mark up the ones that are smart?

 

[ericmark]

Which app? In the main google home controls the bulbs, with voice commands, but this is a secondary app, the primary one would be smart life, tapo, etc, and we have from time to time swapped bulbs, I know we have one or two odd ones, one which does not use an app, but a remote control, it should be in guest bedroom so they can turn off/on lights in bed, but bulbs do get moved around.

I know we got some smart bulbs cheap when pound land was selling them off, before changing owner, and never programmed in, as not required as yet, and bulbs have lost and regained internet contact, back in 2019 when we moved in I knew which ones were which, but now only know regular used ones.

With LED bulbs in 5 years likely changed 4 failed bulbs, and the one just changed in the flat, rarely used, but easy to leave light on for days, smart bulbs I will program in an off command at 9 am so can't be left on for days, but standard bulb in seldom used room easy to miss it has not been switched off.

 

[robinbanks]

You mention smart bulbs as a defining characteristic but then the way that last post is written it doesn't seem like you're really that interested in using the smart functionality?

 

[big-all]

as an aside
as a rough guide, very rough to keep it simple and easy to convert
to convert old-fashioned watts to lumens equivalent multiply by 13 so a 100w old fashioned =1300 lumens and in reverse 1300 lumens =100w

also as a very rough conversion 1w burning for an average 10 hrs a day equals £1 a year at 27p a unit [as in 10wx365=3650w ]
off course iff your units are less it will cost less but for simplicity and make it easy to scale up or down its round numbers

as an example a normal 80w light bulb will be £80 a year and the equivilent led bulb off say 6.5w will be £6.50p a year

Exactly. That's why I wrote/asked (with no reply as yet) ....

Smart bulbs should have some sort of FCC ID on them, shouldn't they?
