Consumption lamps with ampoules G23 G24 * GX24 * and 2G *!

[Christophe]

We have tested the actual consumption of a lamp fitted with a G23 bulb and it is much higher than the indications given by the manufacturer and seller.

So be careful with this type of bulb!

Summary of the test:

Desk lamp brand "Lucide" (ok it is very ugly, although 20 years ago it had to tear) paid € 5 at the end of stock out of curiosity ...



Label (sorry for the quality it is a reflective label so very hard to photograph well):



OSRAM bulb with 23W G11 base.


Measured consumption: 37,60W.



Constant consumption after 3 minutes.

Overcapacity coefficient: 37,60 / 11 = 3,42 is a measured power / power ratio of 342%!

conclusions

Beware of compact fluorescent lamps with G-base tube (G23 G24 * GX24 * and 2G * or * = more specific references) where the transformer is external (unlike compact fluorescents in E14 and E27) and which consumes (in our case) the equivalent of 2,42 times the power of the bulb.

So we end up with an overall consumption of 3,42 the power of the bulb and therefore the power indicated on the box!

It's a safe bet that this is the case (coef multiplier greater than 3) with all fluorescent bulb lamps with external transformer (i.e. with G * base).

If these measures could be confirmed or denied by a member of the forum That would be nice !

Conrad donates these bulbs for energy saving bulbs: http://www.conrad.fr/webapps/lampe_eco_culot-36.html

I quote : "These energy saving lamps have an 8 times longer lifespan for only 1/4 to 1/5 of the consumption of a standard incandescent lamp of identical brightness."

If our measurements are confirmed in all cases of use of a G23 base (which is very likely) it would be necessary to systematically multiply the consumption given by 3 and we would lead, certainly to better results, than with a conventional bulb but significantly worse than the fluorescent bulbs in E27 and E14 ...

Beware of the radiation emitted by this type of bulb.

Of course, check this information for yourself (by measuring the electromagnetic fields around).

Ahhh is that why it kills flies and midges?
But a neon or a compact fluorescent must be the same, right?

ben measures above I already made and bof not very different from a simple filament bulb and the 2 was 50% above a socket free of any connection.

good, you take a socket (E27 in this case), you measure the empty socket, result 320 (do not ask 320 what, we make a comparative measurement therefore only compare with other measurements made under the same conditions ).
You mote a compact fluorescent result 440, then a filament bulb (name "Kryton" 40w that's all I have as a classic bulb ) result 440 ....

the conclusion, well if I trust the measuring device ........?, I don't see the difference.

Let's refocus the subject.
The G23 bulbs are very close to the fluorescent tubes.
After a look at another forum or experimenters have put the electronic "balast" of a 15w fluorescent bulb
on a 36w tube.

For my part I did 3 tests on 1 tube 18w
1st Original assembly:
340mA Cos (phi) 0.37 29.64Watts
2nd electronic ballast 15w (recuperated fluorescent bulb)
70mA Cos (phi) 0.86 11.76Watts
3rd replacement of the 47nf condo with a 10µf
400mA Cos (phi) 0.13 13.8Watts

Small flat for the electronic ballast which reduces the light intensity of the tube by about 1/3 compared to the 2 other assembly.
(Luxmeter measurement at 1 meter live)

[delnoram]

Last tests to date:
1 fluorescent tube (often wrongly called neon) 36W 1.2meter
Original mounted with a 0.047 µf capacitor
Conso 44W (0.4A x 228V x cos (phi) 0.48)

Mounted with 1 capacitor (start) of 4.7µf
consumption 34W (0.19A x 228V x cos(phi)0.78)

i.e. 10W of gain and a reduction of half of the current debited by the wires.
Obviously at the cost of a starting capacitor, it should not be expected that it was economically profitable right away. At 3 hours of lighting per day more than 3 years to amortize the condo. (That said a recuperated condo is grastos , the price of kW can fly very well and the number of hours of lighting can be significantly greater than 3 hours)

[Christophe]

Uh what is the price difference between the 2 condos?
