Neon that cracks and blows the circuit breaker replaced by 230V Led Neons

[Christophe]

Ah well, you can pay him a restaurant more often in Mamita!

I modified my answer I read too quickly ... replacing 100W fluo by 28W led seems short to me ...

But the 28W data gives a much better performance (107 lm / W) than my 36W at 3150 lm (87.5 lm / W)

Power: (in Watt) 28W
Voltage: (in Volt) 220V
Frequency: (in Hertz) 50Hz
Brightness: (in Lumens) 3000 lm
Illumination angle: 180 °
Length: (in centimeters) 150 cm
Lifespan: (in +/- hours) ~ 15h
Energy class: A +
Guarantee: (in years) 2 years
Certification: CE

How many lumens is your 50 up there?

Otherwise there are those there in 150 cm 50W LED ... it must spit and you can probably remove 1 out of 2!

Power: (in Watt) 50W
Voltage: (in Volt) 220V
Frequency: (in Hertz) 50Hz
Brightness: (in Lumens) 4500 lm
Illumination angle: 120 °
Lighting color: (in Kelvin) 3000K / 4200K / 6400K
Lifespan: (in +/- hours) ~ 20h
Energy class: A +
Guarantee: (in years) 2 years
Certification: CE

There is also a 150 cm 36W model ...

Good tomorrow I attack the neon lights of the kitchen!

So I downloaded a luxmeter apli on my laptop .... At 20 cm from the two hot neons I go up to 8000 lux maximum ... Two meters lower (at 1m from the ground) I am between 750 and 800 .. .

A thin ... How to convert lux lumen ... with neons which have a lighting angle of 360 ° ... On the other hand it allowed me to notice differences in performance between the (identical) luminaires of my workshop ... it goes from 700 lux to 850 at the same distance from the devices ...

[Christophe]

Which exact app please? I will do the same ... We will be fixed ... (although it must depend on the phone too ...)

This will give us an idea ... We are not close to 50 lux for products supposed to provide thousands of them

Should be able to compare at equal distance with the same type of lighting, including lumen and known brightness.

A bulb emits at a point, while a tube, over its entire length and the amount of lumen corresponds to the emission at all points, in lux it is a measurement at a point.

20-year-old tubes must have lost a lot of light, electrode wear and metal deposits on the internal walls.
In addition, the old large diameter tubes had lower efficiency:

T12 or T38: diameter 38 mm,
luminous efficiency = 40 to 70 lm / W;
T8 or T26: diameter 26 mm,
luminous efficiency = 65 to 95 lm / W (at 25 ° C ambient temperature);
T5 or T16: diameter 16 mm,
luminous efficiency = 85 to 105 lm / W (at 35 ° C ambient temperature).

The brightness also depends on the IRC incice indicated on the tube https://energieplus-lesite.be/technique ... orescents/

I have EvMeter it's very light and without ads

I installed the app and I have exactly the same 8500 at about 20 cm and 800 at 1m from the ground ... under 1 single neon (but the 2 are on, the other is about 3 m away see the config on the photos : https://www.econologie.com/avantages-co ... -halogene/ ) ...

In short, you can switch to LED neon lights with your eyes closed, Mamita will be happy!

Be careful not to forget the modification of the wiring ... it's not LED starter neon lights

The only uncertainty is the actual lifespan ... Shall we talk about it again in 1 year?

It is a surface calculation considering that the luminosity is constant over the whole "virtual measuring cylinder", see here:
https://www.econologie.com/eclairage-pu ... on-lumens/
computer-electronic-electricity / luminosity-of-a-bulb-conversion-lux-and-lumens-t2382.html

Application in my case:

Virtual cylinder 40 cm in diameter by 120 cm.

Measuring area: 0.4² * Pi / 4 * 1.2 = 0.15 m²
Lux: 8500 lm / m²
So Lumens: 1300 lm

It does not stick too much ... I would have to measure the "20 cm" better, I did a little bit there ...

With 30 cm that would have given 2900 lumens ...

Strange knowing that:
- I have more light with my 2 LED tubes than 3 old 36W fluorescent tubes ... (or it was these old tubes that were tired, they are still made in France, some I think ... it is a good indication of their great age !!?)
- we know that the LED output is better than fluorescent ... so I do not see how fluorescent can be brighter (not to mention transformation losses ... 36W is the power that arrives at the fluorescent tube or good to the ballast ???)

Several things influence the feeling of lighting.
- Your tubes were old and indeed the fluorescent lamps lose a lot of brightness with age
- The angle of emission of the light ... your old tubes illuminated 360 °, your LED tubes illuminated at an angle of 120. Before you illuminated your ceiling (probably for nothing because not very reflective) while with the led tube 100% of the light is emitted downwards and is "useful"
- The color temperature, the LEDs emit a generally cooler light *, which gives an impression of stronger brightness.

* Moreover, honest sellers of led light sources give the luminous flux in lumens depending on the light temperature option chosen, and very often for the same sources it is observed that the efficiency drops at the same time as the temperature light.

[Christophe]

On the felt yes ... but not on the lumens announced by the manufacturers ...

The real angle tends more 180 ° than 120 ° ... and it does not influence the lumens ...

Some neons are tinted over 180 ° so as not to illuminate the ceiling too much ... mine is the case.

My tubes are 3 years old, they are phillips out of the 12 in place, two are already grilled ....
