LE Dimmer and Clipsal TPDL100

Anyone used the TPDL100 downlights from clipsal with the LE dimmer (5508D1A)?

How was the dimming performance?

 

Hi jasonson
Armed with specific details of number of fittings per channel and dimmer model I would ask the supplier to guarantee satisfactory performance or be able to refund.
The supplier is the person you will be dealing with if you run into any problems.

 

Was just wondering if anyone had some installed in the field already and if the dimming was smooth, good range and flicker free.

Clipsal tells they will be fine but I haven't gotten around to buying any to test them yet.

I will have between 2 and 6 per channel.

 

Classic Clipsal..

Www.clipsal.com/load well and truly out of date..

Latest TPDL brochure states cbus dimmer compatibility but no details.. One might interpret this a certain way and without details or clarification one might think if it doesnt give satisfactory performance, that it would possibly fall under the aus consumer gaurantee.. ;-)

I don't have a CBUS LE Dimmer unit spare in the workshop.

I only have a universal at the moment.

Gonna hook it up to the old fashioned 30 series LE Dimmer mech and check it out

 

Hi jasonson
The data sheet Roosta linked does show a leading edge mech in the picture.
If you want to be sure I would contact Clipsal and see if they have a data sheet with min and max lamps per channel for your particular dimmer.

I wouldn't necessarily conclude that a LE 30 series dimmer mech will perform exactly the same as a LE CBus dimmer.
If Clipsal can't provide a data sheet for your dimmer I still think you need to ensure they are willing to refund the product.

In the past I have found Pierlite provided detailed data sheets for CBus dimmers.
MELEC and I'm sure other manufacturers provide some dimming tests.
Maximum number of fittings will be much less than the load rating of the dimmer channel.

Again I think it is important to have the backing of the manufacturer for your exact application.
In my experience the warranty length is about the life to expect from an LED downlight and while they do save energy I would factor that into any cost saving potential.

DarylMc,

please see the attached data sheet for the LED Dimmer mech shown in the datasheet posted by Roosta.

I may be missing it here but they are trailing edge dimmers with preset minimum level and controls to handle the inrush current drawn by LED lights when first turned on.

What Model and brand downlights have you had good success with on Cbus LE dimmers if I may ask?

Edit: I read this after posting and it reads like I am ungrateful and rude. I'm not and I appreciate your and Roostas replies. I am trying to educate myself as much as possible on compatible loads as the CBUS Universal Dimmers are far too expensive for use in my own home.

 

Finally tested a TPDL102 (only test unit I could get my hands on) with a leading edge dimmer mech, it was not good. Poor dimming, audible humming and flicker below 20%.

 

My experience with various LED's on CBus dimmers is quite limited but I have had predictable and good results from Pierlite products on CBus LE and Universal dimmers in my own office when following their specifications.
As I mentioned and worth considering is the lifetime which was about 3 years in my application.
I don't expect many LED downlights would do much better but I am monitoring other LED downlights with my customers.

MELEC is a company which is located relatively close to us and I think it is worth at least asking them about their products.
I like to support companies like Pierlite who actually provide dimming specs for CBus dimmers.
MELEC has a bit limited specs, maybe Clipsal too evidently but I think it is most important to get some sort of guarantee of suitability in any case.

For applications where I have used LED downlights, very few have been the diffused opal lens type like the Clipsal ones you linked.
I have installed a similar style opal lens Atom brand in a non CBus application.
That type of LED downlight does provide a very wide beam angle and would be good for maximum illumination of a room.
For myself and some of my customers that is not the effect they are looking for.
If I was after that style I would be asking MELEC some questions.
I've installed a bunch of Osram in non CBus dimming applications and found dimming information and support very poor.
Poor as in not recommending them to be used with CBus dimmers.
Poor as in problems with Clipsal dimmer mechs of any type.
Wouldn't even consider them for CBus.

Pierlite is going to give you predictable results on CBus dimmers when you follow their specifications.
You need to ask but if Clipsal can't give you guarantee of suitability or specifications for CBus dimmers I would be looking elsewhere.

That is my experience and it is a bit limited but I've found dimming any LED with phase dimmers CBus or otherwise can be quite a difficult task.
