Eager to get pilots and aircraft owners to try the new Parmetheus G3 landing light, WAT (who you may know better as Whelen) has introduced a trade-in and trade-up program that offers a rebate of as much as $70 toward the new G3. The program includes both PAR-36 and PAR-46 lights in 14-volt or 28-volt versions from a few popular manufacturers. Qualifying models from AeroLEDS, Aero-Lites and Aveo Engineering can earn $30-$70 in rebates.
For those with earlier versions of WAT’s Parmetheus landing light, an upgrade to the current G3 will net a rebate of $50-$70, depending on the older model.
The Parmetheus G3 is available in both the PAR-36 and PAR-46 sizes. Both run on 14 or 28 volts. While the G3 in the smaller PAR-36 size can be ordered as either a spot-beam landing light or a wider-beam taxi light, for now the PAR-46 bulb is offered only in the landing-light beam style. The smaller lamps pull less than 4 amps at 14 volts, while the larger PAR-46 lights come in right at 6 amps on 28 volts.
WAT says the Parmetheus G3 in PAR-46 size puts out more than 200K candela initially and is still above 120K candela after 45 minutes. The PAR-36 version puts out more than 130K candela at startup and maintains nearly 70K candela after 45 minutes. All LEDs suffer from some sort of intensity rolloff thanks to heat-management strategies.
The rebate/upgrade program runs through April 30, 2023.

The G3 PAR 64 is coming soon according to the website!

Based on getting an email from Avweb exclusively about it and also came from Kitplanes as well, I’d say paid.
All of those units loose 40+% output within 5-15 minutes, significantly faster in a hot engine compartment.
Xevision ( XeTREME LED ) A well established (20+ years) OEM HID Landing and Taxi Light manufacturer) makes a Par-36 (obvious why not listed here for rebates) Starting output is almost 325,000 Candela, by far the industries highest and slowing dimming VERY slightly to 320,000 even after days of continuous operation still 320,000 Candela. How is this extreme sustained performance accomplished ? By using premium Extreme power Cree LED’s operated within Cree recommendations for very long life, using collimating 10 degree optics, very large compared to all others & Active cooling. Very effective illumination out well past 1/3 mile. The optics are even sealed with Nitrogen. Included std. is a faster strobe function, no additional wiring needed. Upgradeable, Modular and repairable. 5 year/2000 hour warranty.
Yup, LEDs can run very hot if they are run at high current and the power is not dissipated to the air or the mount.
A forced air cooling fan is a good idea.
The 2 LED landing lights that I use , I tested and at the rated 2 amps the case exceeded 170 degrees F. Class A electronics is good to about 220 degrees, but at that temp the life is affected.
The ‘old’ incandescent lights were just fine running at 200 degrees….it’s just a filament, not electronics..!
Jim H in CA The XeVision units only get warm to the touch even after days of continuous operation, this due to patented technology getting the heat efficiently from the LED junctions (base) out to the heatsink and actively cooled with a waterproof fan. The XeVision XeTREME LED units are 100 watt, see my prior post above yours.
If your case is at 170, the internals could easily be at 200 F.
