Yes these are drop in replacements for PAR36 bulbs which the Cherokee uses. The landing and taxi lights have different beam patterns.
Q: Will these work to replace the landing and taxi lights in a 1980 Cessna 182Q?
Yes, the Cessna 182 uses a PAR 26 size lamp. Since the Parmetheus G3 is a PAR 36 size and the voltage operates from 14-28 volts, this will work as a drop in replacement.
Q: For a Cirrus SR22 G1, would you use the taxi or landing light version?
If you only have one light on the aircraft, Whelen recommends using the landing light version.
Q: Will this replace the Grimes landing light on a 1946 Cessna 140?

Q: Is the G3 a PMA product an aircraft owner can install to replace a PAR 36 4509?
Yes, this is FAA PMA drop in replacement for the PAR 36 lamp size.
Q: Which LEDs are used and please, specify the lumen / candela figures?
These use Cree LEDS and they average around 9k-11k candela.
Q: What is the beam angle of the Whelen Parmetheus G3 Par 36 landing vs. the taxi version?
G3 landing light is 10 degree x 10 degree conical. The Taxi light beam pattern is 40 degree horizontal and 10 degree vertical.
Q: In your Q&A, you said that the G3 is a PMA product and it is a drop-in replacement for the 4509. I do not see on the Whelen website that the G3 has a PMA. Can you confirm that this lamp has a PMA and does not require the STC to install as a drop-in replacment for the 4509?
Yes, the Parmetheus G3 is FAA-PMA certified.
Q: Is this Whelen G3 a drop in replacement for a Beechcraft 35-C33? I think the GE pn# is 4522
The Beechcraft 35-C33 is on the AML list for the Whelen Parmetheus Plus 14V Landing Light. The STC for the Whelen Parmetheus G3 utilizes the AML for the Parmetheus Plus for it's replacement standard. The Whelen Parmetheus G3 should be a suitable replacement for this aircraft using the current STC authorization SA00344BO.
Q: How does the brightness of the G3 compare to the Teledyne Alphabeam?
The G3 should be brighter. We do not have the exact specs for the Alphabeam because it is no longer available.
Q: Are you sure about Whelen using candlepower? If so, the 10k candela you mention in other answers is hardly enough to read a map by, let along be used as a landing or taxi light - thats why Im skeptical about the candela claim. Thanks.
1 candela is 12.57 lumens, so that would be around 125,700 lumens but candela and lumens measure two different aspects of intensity. Whelen gave us the candela rating directly.
Q: Will this WHELEN PARMETHEUS G3 PAR 36 LANDING & TAXI LIGHT fit a 1974 Beechcraft Sierra?? (BE24R)
Yes, the BE24R uses a standard PAR 36 size landing light. This will fit that aircraft.

Cessna 182 uses a PAR36 size. This unit will fit and replace the incandescent unless other unknown modifications have been made to the airframe.
Q: Will this be a direct replacement for a 1978 V35B Bonanza taxi light on the nose gear?
Please confirm the lamp size on your aircraft is a PAR 36. If it is, then this will fit as a drop in replacement.
Q: Will these lights work on a Piper Tomahawk P-38? If so, which do you recommend?
Yes, the Piper PA38 uses a PAR 36 lamp size. Since this is a PAR 36 lamp it will fit.
Q: For a Piper Tomahawk, do you recommend the landing light version or the landing light + taxi light version?
Some aircraft require both a landing and a taxi light. The landing and taxi lights have the same illumination specs, the difference is in the beam angle. You need to verify your aircraft requirements to determine if you need a landing light, a taxi light, or both. If you only have one PAR 36 lamp on the aircraft, Whelen recommends using the landing light version.

These are priced and sold individually. Yes, the 172P uses a PAR 36 size lamp.

Yes, the 182T uses a PAR 36 size lamp. This will work as a replacement.
Q: Regarding Whelen Parmetheus™ G3 PAR 36 Landing & Taxi Light FAA-PMA: Does direct replacement mean that I would not need an A&P to do any STC pare work for the installation? I can do the installation on my own with no paperwork other than a logbook entry?
The install instructions note. "Determine that the Landing or Taxi light characteristics have not been substantially affected, per 14 CFR 23.1383/27.1383. If required, update aircraft records utilizing FAA Field Approval (Form 337) or equivalent."
On most aircraft it should be simple logbook entry, but you would need to verify that with your IA.
