The old Whelen drew just over 4 amps, the 650s draw about .8 amps is what I was trying to express.You found LEDs that contribute to the power grid? Amazing!
Go on here and send James an email, and he'll be able to let you know what you need. He also has the best prices on Whelen stuff anywhere.

For those who have put in the Orion 650's, they are approved, and all needed paperwork is available correct?
I ordered those, and new fiberglass tips as @bnt83 did. They should be here soon.
The 650's are STC approved for a large AML. They are also TSO'd. Documents are available at the WAT website.
I don't understand FAA processes, but as it was explained to me, the STC came first, which required a 337. That requirement was later supplanted by TSO status, so that they can now be installed as a minor alteration with a logbook entry. There are pages of debate over this topic on PoA and elsewhere on the interwebs.
To add to the above, in order to sell an article/part a vendor needs a design approval and production approval (Part 21). An STC is only a design approval and is applicable to single or multiple type certificates (TC) depending on which type STC used: One Only STC, Standard STC, AML-STC, or Non-Interference STC. A TSO is a design and production approval and is applicable to a technical standard and not a TC.I don't understand FAA processes, but as it was explained to me, the STC came first, which required a 337.
