Vertex Illumina UV module emitters

[Eud]

I'm not sure if anyone here will have info on this, but does anyone know which emitters were used in the Vertex Illumina UV modules? They have 3 emitters each, which sure look to me like chinese black box UV emitters. Bridgelux or a clone of them.

I am repairing a fixture for someone, and it is running the latest firmware that enables the accessory modules. I can see the UV modules and can try to turn up the intensity in the "Compose Colors" mode to see if they work but they only come on really dimly. In addition the Demo mode doesn't light them above dim either.

I'd like to try to desolder and resolder the emitters on one, since these modules were made in 2012 when UV emitters were not super high quality. I have some chinese ones that seem to be OK in my experience and fit the same shape.

Anyone know if the originals are likely the chinese ones and if I'm barking up the wrong tree here?

Here's a pic of the module:

Just FYI, violet does appear much dimmer to the eye. ( you probably know that , just want to make sure)

If they are the same footprint I would bet you could swap them. The V forward should be near enough and a diode is a diode. My worry would be that it is a potentially expensive mistake on hardware not made anymore.

Yep, I know that the violets are supposed to be dim to the eye. One of the 12 total emitters lights up properly, but the other 11 do not.

They don't work anyway, so I see little risk in trying, but I would rather someone had some dusty, never sold, new old stock around, heh.

Thanks.

Just in case anyone comes looking in the future. The emitters seem to be nearly impossible to get off the board and new boards seem to be totally unobtainable just a few years after the light was put into service.

The emitters themselves are glued with some kind of very strong adhesive to the board. The plastic casing, after being exposed to UV for a period of time, basically crumbles to dust if you try grabbing it to tug on it.

Plus, whatever process was used to lay down the traces on the circuit board, the copper doesn't adhere well to the board and came off as I was heating the pad to get the emitter off. The mask is good though.
