Dimmer und Philips WarmGlow GU10

[Keepcurry]

The BJ dimmer was one of the newest revision which should work with HV-LEDs. The glowing was about as bright as the lowest dimm-level with the new MDT dimmer. With a halogenbulb parallel to the LEDs and without Kompensator, the behavior of the BJ dimmer was ok, so I think a GLE would have been better for me than the Kompensator.

I think, if a halogenbulb parallel to the LEDs doesn't remove the glowing, the GLE also won't.

Thanks,
The BuschJäger 6197/12-101, doesn't seem to be compatible with HV-LED from beginning? Whilethe Jung from V02 are rated to work with HV-LED.

About glowing lightly.. Mine are actually glowing quite much, so much that I can navigate in the room without problem, and I wanted my lowest dim levels do be lower than the glowing actually... =/

See theese images, this is without the BJ compensator.. I would say that when I have dimmed down to minimum, even with the BJ compensator, it's just 1-2% away from the "glowing"

I haven't found any good reference pictures that illustrates other glowing problem, to determine if my glowing is more intense or not.

Here are 2 pictures;
- The first shows 4 LED dimtone + 1 halogen in same lamp, the halogen is dimmed down to lowest, but LED is brighter, when I dim up, first the halogen dims up so it's equal with the LED, then they all together starts to dim to brighter. I would say the LED's are stuck at 5% brightness and wont go lower.
- The second illustrates the after glowing

I will try to get my hands on a 4-35W, but they are not 8€ in Sweden, we are talking about 15€

Hi sx3,

I used a BuschJäger 6197/12-101 Dimmer with Philips WarmGlow (35W) at first. I had the problem that the LEDs were glowing lightly after turning the channel off, so I also used the BJ Kompensator. In this combiantion I also couldn't dim the LEDs completely down, maybe to 10% and they were glowing about 5sec after turning off. Because of this and some other issues I have changed the dimmer to a MDT AKD-0401.01. It works really fine, even without BJ Kompensator, and the dimming ist almost perfect, for me.

Greetings Timo.

I think an investment of 8€ for a new 4W bulb for testing is no bad idea :-)

[sx3]

Alright, I use the Busch-Jeager Kompensator 6596, and use 2-5 lamps per channel.
I don't know the tech inside the 6596, if it's the same tech as a GLE, as is PTC resistor.

Have anyone who tried both the GLE and 6596 report if there are any difference in how deep the dim will go?

Also interested if someone tried both the 4-35 and the 4,5-50 W, if there are differences in minimum brightness

[dreamy1]

I use the GLE...on one dimmer channel 2-6 lamps are installed.

[sx3]

Btw Dreamy, are you using BJ compensator or the Eltako GLE?
Could this have something to do with it? That the load is not enough on the dimmer? How many lamps do you run on a dimmer channel?

[sx3]

Alright, so when setting basic brightness to minimum brightness(%), the level will per automativ be disabled right?
Iäve now testet all the different loads, I can't really tell any difference none of them goes lower.
Not even if I dim down, I can go further lower than the scene already set at 5%

Maybe I should try with 4-35W see if this is the case

[dreamy1]

...here is my setting: minimum brightness 1%, basic brightness level disabled.

You wrote that you use scenes with 5% brightness....what happens if you are dimming with a KNX switch sensor (this will allow going down to 1%)?

[sx3]

Level 1 is the lowest and it states "not for use with booster"
I cannot disable this function.

Maybe I should try Trailing edge, even though Philips says the LEDspot should be run in leading edge.
Maybe I could choose leading edge without HV-LED also, maybe that will work better

[dreamy1]

My Gira dimming actuators are revision I02.

Can you choose basic brightness level lower than level 1 or can you disable this function? I can't remember that i use this function...i will have a look at my settings and come back to you.

[sx3]

Thanks for your reply,
Du you use the latest HW revision? IO3 or IO4?
Mine are V02.

I'm not sure I understand what you mean by "Phase broached or phase section", do you mean Trailing edge and leading edge?
If thats the case I have tried both HV-LED Leading edge and Automatic calibration, it doesn't change things for me, still the same.

I have set the dimmer to both basic brightness (level 1), and also tried minimum brightness (1%), but my scenes that I recall I can choose 5% as minimum or basic brightness, but it is still the same. I would the brightness level is about the same as when dimmed down a halogen to 20% perhaps, if I fit a halogen instead I'm able to go much lower.

Is there info on the minimum brightness for the DimTone lamps, how many lumen they should output?

[dreamy1]

My Philips 4W Dimtone bulbs in combination with a Gira dimmer are dimming down to 6 lx (measured with lux meter), comparable with candle light atmosphere.

Maybe you have a minimum brightness parameterized in your dimmer application? Phase broached or phase section?

Hi guys,

I have now installed some Philips DimTone 4,5-50W with my Jung 3904 dimmer.
Just like most of you, I've had problem with afterglow, I installed the Busch Jaeger compensator and now it works good!

But, in my opinion the LED are VERY bright even though I have dimmed down to minimum brightness.
Is the minimun brightness the same for 4-35w as it is for 4,5-50w version of the LEDspot with dimtone?

I have'nt noticed any difference between 10 and 5% minimum brightness, and it's still very bright, not very cozy in bedroom when making babies haha.
Is the minimum brightness level different between manufactures? in example if I change from Jung to MDT or ABB or something, will the minimum brightness change or is it the same?

Regards
