Pulsing LED Strip on dimmer?

Sorry - edit.Dimmer is the GJP100W model. Strip is Aurora or Eterna - same company I believe.

Well some combinations of LED driver (really small switch mode supplies that rectify the mains and then chop it to an AC at an supersonic frequency through a really small transformer core) and some dimmers, that are really just circuits to  chop bits out of the 50Hz mains waveform result in sad effects where the chopping waveforms of the switching supply and the dimmer drift in and out of step giving flicker at a visible rate. There is not a lot to be done  other than change one or the other

This supply is supposed to be dimmable by a triac- the old fashioned sort of lamp dimmer. 
I cannot find the GPJJ100W  you mention anywhere - do you have a datasheet ? - if it can emulate a leading edge dimmer, like a triac, that is your best bet, but it may not - then the next course is to ask the LED driver makers which dimmers they expect it to work with.


Edit link to the dimmer    Now I think  you should try mode 2.


CHANGING THE DRIVING MODE You may be able to improve the performance of your lamps by changing the driving mode to MODE 3, or with some types of lamp MODE 2. NB. It has been noted that some LEDs do not show the programming as well as others. If you are having difficulty seeing the programming steps, you can replace one LED lamp with a halogen one for the duration of the programming in order to see the steps more clearly.
1. Switch on and set the dimmer knob to the MAXIMUM position (turn fully clockwise).
2. Turn the lights off and back on again. OFF – ON, roughly once per second.
3. Repeat step 2 at least twice more. OFF – ON – OFF – ON, roughly once per second.
4. The lights will step up and down in brightness to show that the dimmer is in CONFIGURATION MODE, then either stay at a low light level or go off.
5. To select MODE 3, first turn the knob fully anti-clockwise then fully clockwise. For MODE 2, just turn the knob fully anti-clockwise and leave it for a couple of seconds.
6. The lights will FLASH 3 TIMES or TWICE to show which mode the dimmer is in. The dimmer can be operated normally in the new mode.

[To check which mode the dimmer is operating in omit step 5}

Trailing-edge mode (MODE 1) by default.
The alternative trailing-edge mode (MODE 3) may improve the performance of some dimmable LEDs.
Mode 2. This is a simulated leading edge mode (not TRIAC)

Hi Mike,

Thanks for your input. Reading down a bit reveals the following - Note the last line - not suitable for triac type drivers. Not sure what the difference is between a VPRO and a VCOM.

Might try mode 2 just to see if it makes any difference.
THIS SWITCH IS NOT SUITABLE FOR
Non-dimmable LED lighting
Non-dimmable fluorescent bulbs and tubes
Wire-wound or toroidal transformers
Electric motors (e.g. Fans)
TRIAC dimmable drivers (Choose V-Com series dimmers)

And if not have a root round for an older style dimmer. Quite often the giblets are transferrable between fittings,  as they are a single hole fixing in the faceplate. There is almost universal agreement between makers on the hole size, though not the thread on the locknuts.

Thanks Mike.

The Aurora Enlite EN-LEDD7512 driver is a triac constant voltage model and the link to the LED strip (part no Aurora Enlite ST100IP) states that it requires a12VDC Constant voltage supply. The wholesaler said that the Aurora catalogue states that the driver model is compatible with the strip.

No mention of compatible dimmer types though.

Will try mode 2 on the switch first, then if no good, will have to try a VCOM type switch instead.

Ok, Update time.

Raised a ticket directly with Aurora tech support, who responded with a suggestion that the load presented to the switch may be too small for it to work effectively, so then raised another ticket with Varilight tech support, who responded with a suggestion that I replace the switch with one suited for driving triac-based led drivers from their VCOM range.

Many thanks for your input.
