Thanks! I will check that out too.

for M20K with wing lights adjustment is pretty specific for adjusting lights.  I also have the Parmetheus Plus and don't feel they are all that bright.  Of course landing with lights off at night is sometimes a good exercise just in case.  Although I'm most disappointed with taxi lights as there is not much light around my hangar and it always seems way darker than I'd like and they haven't repainted taxi lines around the older hangars in ages.

I agree -- I don't need the landing light except to see a suicidal deer. But taxiing is a little nerve wracking at an unfamiliar airport in the dark with the Plus. 

The procedure above is for the wing-mounted lights. I did that carefully when I installed the Plus lights.

Also, something to watch out for: The wing mount retainers have a notch that fits in a key on the back of the bulbs. The notch is off by 90 degrees for the proper orientation of the WAT taxi lights which have a lens designed to spread the beam horizontally, so you need to make a new notch in the proper location. Looking at the LED layout of the G3, this may apply to the landing lights as well.

I found that Parmetheus Plus does not illuminate as well as the OEM incandescent bulbs. I am going to replace mine and throw the Plus’ bulbs away — I would feel bad selling them to some other sucker.

There is a procedure in the M20J Service Manual for aiming the wing-mounted lights, but you have to “wing it” for the cowl-mounted light. When I had a 1978 J with cowl light it was aimed high and would not adjust properly. I found that a kit from Mooney that shock mounts the bulb to improve its life had been field installed incorrectly. So you might check that if the screws don’t have enough travel to aim it where you want it.

Someone posted about the correct orientation of the LED's is 90° from the factory incandescent which were oriented to have longer filament life with a symmetric pattern.  They notched the metal carrier ring to permit the LED bulb to be rotated.  Does this apply to Parmetheus in your J?

Yes, I think it is probably the case for all the wing-mounted lights.

Well i was going to do a comparison landing test to show the difference but after three different iphone holders that failed to keep the phone from either falling down or vibrated at just the right frequency to cause my image  stabilization to go berserk In the recordings i gave up and you will have to settle for the standard light on the hanger door test and since i had a free afternoon i had to shine it on indoor doors as it was still daylight outside. I had 2 landing lights that i think were PARMETHEUS PLUS LED landing lights so i replaced one light with the G3 landing light so you can see the side by side comparison and then replaced the other landing light with the G3 taxi light and the beam is Definitely wider I think I’ll have a good coverage with both on see for yourself. I’ll be selling my old ones if anybody wants a landing light say $125ea?

The second video above shows why the LED taxi lights needs to be oriented specifically.  I think Whelen says taxi beam projection is ~40deg wide by ~10deg high.  The lines they are referring to are the ridges on the lens.  Surprisingly I found that my taxi lights were installed incorrectly by previous MSC!  No wonder it seemed dark...

I noticed the led housing does not have a notch so you could mount it any degrees and it would fit, however WAT recommends mounting it with the flat circle on top as it allows any moisture to escape from there and needs to be the highest point.
