test test: SMD LEDs VS VS Halogen CFL

[Christophe]

To do well you should put an ON LINE power inverter just after the meter ...
;
An On line inverter treats 100% of the current that there is where not of the tension on the network, they are pure sine obviously ...

But the prices are logically high for equipment of this quality: a 2 kVa model costs 1500 euros ...

I have one to recover in the garage: it consumes, moreover, almost 100W permanently without load (in own consumption)

Beinwoui, well The only one I keep is for freezing ...

[Christophe]

Are these pure sinuses? Because the rotating material does not like the approaching sinuses too much ...

Well we deviate from the subject of SMD ...

I take advantage of this subject on burnt bulbs to find out what would be the causes of all the bulbs that burn on my chandelier (with 6 bulbs): https://www.econologie.com/forums/ampoules-q ... 10114.html

[dedeleco]

on average I am between 235 and 237 V

It's a lot like average that must be at 220V between 200V and 240V max (I saw at a home at the end of the line EDF, 180V (big cold and all before me took electricity to heat and it does not nothing was left to run the cooker and the microwave oven with electronics that hangs at 200V and night in the summer like you, close to 240V excessive, no one taking power !!).
In my opinion this is enough to burn the light bulbs that dissipate a power that believes very quickly with the voltage: I remember so many lamps that jump at night lighting!

For fluorescent lamps, it is their power supply electronics which does not support such a voltage (capacitor and semiconductors very limited in voltage to obtain a low price)

Finally momentary voltage peaks of more than 240V are extremely destructive !! (inductive starts or stops with large thyristors and lightning strikes in the vicinity!)

dede, please copy your answer in the subject he just made: https://www.econologie.com/forums/ampoules-q ... 10114.html

please

I just wrote the new correspondent: https://www.econologie.com/eclairage-a-l ... -4304.html

The cow has been doing it since April 21 that I had not made ... not bieeeeeeeeeen ...

Here is one of 172 omnidirectional smd leds in E27!
Baleze!
The price seems to be too: € 69.50



Can it be used on the outside in a "over the door lamp"?

[Christophe]

Uh dear not for you but I find it really hideous ... not to mention the price really too bad as you say ...

How many lumens is it?

Otherwise we just tested this model (from velleman also like smd) which is given for 550 lumens (equivalent to a fluorescent from 12 to 14W) and 7.5 W of consumption (yield 73 lm / W).

It lights really well (there is no cone effect as you might think when you see it) and the look is in this case, frankly acceptable, even 1 hair design.

Problem: the public price would still be around 50-55 € ... for me it's still too high especially at the moment ...

While waiting for this to drop, it is very good in our WC (even a little too loud compared to the fluorescent 11W that there was before ...). It is probably equipped with a Power Led.

A bit of design? I find it superb!
