Compact fluorescent light bulbs: actual consumption and tests

[Christophe]

all the tests no, there is no difference neither for fluorescents for the LED spots nor for the transformers.
where it is necessary to redo it is on the device with a motor I think. )

Ok but I'll still check this to be on ... especially the G23 ... then this aprem I may have my luxmetre (ITC 777 you know I think?) So it will be an opportunity for any good ( re) test and thus confirm the measurements!

[Christophe]

Well, I'm going to measure the brightness and power.

Here is the measurement protocol:

1) made in a room without window
2) measurements made in relative (there is a button for that on the ITC-777) so that the little ambient light does not interfere
3) Measurements made on a foot lamp without abas day for E27 and spotlight for E14,
4) 3 measurements made by 0.5, 1 and 2m lamps approximately

I would make a photo of the tests of course.
I would adapt the protocol if the measures are not significant.

[Christophe]

Here I set up the "device" test.

I would finally do 4 measurements:

- direct 2 aligned in front of the 50 bulb and 100cm of the foot of the lamp
- 2 "indirect" which will be more representative (I think) of the atmosphere

I would do photo and 1 scheme.

In any case I foresee a period of heating the 3 bulb minutes (even if it is no longer necessary with new generations of bulbs).

ps: I will take the opportunity to also test the brightness of the torch at 5 Leds and the night light arranged on the shop. The bulb of 22W of the economic spot will also be tested (for the moment without the spot bulb alone on foot otherwise it is not very honest with the reflector)

[Christophe]

I am doing the tests, 3 ampoules tested
It goes well (would miss more than the opposite) ... but already 3 remarks:

1) some bulbs (2 on 3) have a Cos phi = 0.8. and the PM230 takes this value into account when calculating the power.
2) "white" bulbs (one of 6400 ° K) get bcp + lux than yellow bulbs (2700 ° K) so the sensor is not spectrally "neutral" which is normal but ... *.
3) It seems that the whitest bulbs have the cos phi at 0.8. I will confirm thereafter.

* ... this may pose a "problem" with LED bulbs since they are very white ... Lux will not reflect the atmosphere ..

Well it's more than 2 ampoules to test ...

Good if this comment on LEDs is false.
The results of LEDs are CATASTROPHIC ... the luxmeter can not even measure in some cases

In fact the LED bulb is finally ... electric heating with light optional!

[Christophe]

Ayé it's over!

I treat the results and you balance everything quickly!
Maybe still tonight ... I tested 15 bulbs, 4 measures + Wattage for each one so it does a little bit of analysis without talking about the images to be processed

[delnoram]

no indeed the sensor is not neutral, it is calibrated for a color temperature of 2856k.

For your tests I can compare the results to mine.
For LED spots since they are directive their results in ambient light are not really measurable.

As for the cos phi that night he turned on some bulb between 0.80 and 0.84, this morning he does not move 1 anymore.
I had a "yellow" that had 0.84, one from 2700k to 1, and one from 6900k to 1.

I think rather to the design of the assembly that is used for lighting.

Measurement protocol:

1) tests performed in a room without window (our bathroom and yes we do with the means we have ... purists laugh but will have to do more "scientific"). The door is closed of course.

2) measurements made with an ITC-777 multimeter placed on the ground horizontally on different measuring points marked on the ground.



The photocell is calibrated for a color of 2850 ° K. The bulbs whose colors are moving away from this value will therefore have their value distorted (a priori reduced compared to the reality.). All tested ampoules are given for 2700 ° K (very hot light) except one at 6400 ° K (very cold light).

3) measurements made in relative (there is a button for that on the ITC-777) so that the little ambient light does not interfere with the results. It appeared that this ambient light was equal to 3 Lux.

4) Measurements made on a foot lamp, without abas day, bulb placed horizontally always in the same direction (same angle in 2 main dimensions).
For E27 we use the foot lamp and for E14, we use a "spot" lamp placed at the same height as the E27 (see diagram and photos below). The bulbs are all 40 cm ground (+ or - 1 cm).

5) 4 measurements are carried out per ampoule (see diagram below):
- 2 "direct" in the axis of the bulb at 0.5 m and 1m
- 2 "indirect" to 1.36m and 1.55m.

6) The electric power is also measured with a PM230. The average luminous efficiency is calculated in Lux / W. Further analyzes will follow.

Here is the plan of my Testing Laboratory (in truth, my microscopic bathroom ) and some photos to prove that I do not talk bullshit ...

[Christophe]

Here are the results :

1) Gross statements:



Consider the 1er luxmeter test results (2850 ° K sensor).
It's a lot worse than I thought for the LEDs but see rather:

Tests of compact fluorescents: average luminosity on the 4 measurement points related to the real conso given by the PM230:



ps: the Qida, the only bulb at 6400 ° K, is a "cold" bulb that equips this spot but the measurements were made on a naked pellet and not in the spot with reflector (which would have distorted the measurements). It is very likely that there is an increase in the value of this bulb because of its deviation with the nominal color of the sensor (2850 ° K) compared to other bulbs all 2700 ° K.
