WHELEN LED PARMETHEUS PLUS PAR 46 28V LAND P46P2L

July 5, 2022

Direct replacement for the GE 4522 lamp on my 1966 Mooney M20C. Took 30 minutes to swap out, using existing wiring. Couldnt be easier. I now fly with the light on both day and night, which adds a degree of safety on hazy days and at night. A fraction of the current draw, yet still very bright for a landing light. PMA part approved for my plane, too.

Ordered two for two Cessna 172 N models. Both owners were quite happy. One reported that he did a night flight & said what an amazing difference taxiing & landing.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: What is the difference between Parmetheus Plus (part number 11-12981) and Parmetheus (part number 11-09524)?

The main difference is the light output. The PAR Plus is 80% brighter than the original PLED462L. Right now we are currently getting STC and PMA approval on the P46P2L so they would need to do a field approval at this time for installation. (as of June 17, 2014)

Q: Which landing light LED is stronger: 11-12981 (WHELEN LED PARMETHEUS PLUS PAR 46 28V LAND P46P2L) or 11-12978 (WHELEN LED PARMETHEUS PLUS PAR36 28V LAND P36P2L)? Also, what is the difference and what is your suggestion to me?

The difference between these two lights is not stength. They are both very strong. The difference is in application. One of them is used in aircraft that require a PAR 46 size light, and the other is used in aircraft that require a PAR 36 size light.

Q: Is this light (part number 11-12981)wig wag compatible ? If so could you recommend a pulse switch also please.

Yes it is and Whelen recommends our part number 11-08175.

Q: Do you need to install a relay in line with Model # P46P2L? With the incandescent landing light, we would use a 50 amp relay. Should I be removing that relay now?

No you would just replace the current bulb with this unit.

Q: the supply voltage is 28VDC, can we lower this supply to decrease the brightness of the light? Or can we dim the light with an appropriate PWM dimmer module?

Per Whelen, this has not been tested but they suppose it could be done. They were not aware of the practical purpose for this.
