Replacement radion power supplies

[Wildreefs]

I am in search of two different radion power supplies., knock offs, oem is very expensive.

One is a gen 6 xr 30

And the other is the gen 4 xr 15.

The one my gen 4 had read this;

GST90A24-et

The ones I find online say the first part before the dash, GST90A24 , but instead of saying -et they will say -1pm or something like that .

Please advise

Voltage and wattage output is really all that matters.
And wattage only so you don't go below it. Above is fine.. within reason.

What's on the originals?

So I just did a little diving , and I switched my power supply from gen 4 xr15 to the “bad one”, and it’s only works up until a certain intensity, then begins to flash.

So lower then 20 percent, light works on both power supplies, closer to 40, the flashing begins on both the good and bad power supply. So it’s not the power supply.

I then brought 1 by 1, each channel down to 0 percent to isolate which color led is the issue. The last channel, the cool white, seems to be the issue, when bright to 0, all the other channels stay on, even when those other color channels are 100 percent each. The second I try to bring the cool white above 0 percent, the entire cluster flickers.

Question is, can I use this light assuming cool white is always at 0 percent? Or does that have underlying consequences or eventually shorting or ruining other channels or the light itself?

First....no guarantees...
Sounds like the white channel may have a small short or bad component in the driver.

This may cause the ps to enter limp mode when the light starts to draw too much current.

Running w/ white at zero " shouldn't" cause an issue *afaict*.

Ymmv ..

Wouldn't ( shouldn't ) hurt to do a disassembly and clean.
Whites are the yellow LEDs..:)
