What is the brightest G4 base bulb available with a voltage under 28v?

thanks

maybe this one:

it's rated 12V 2000 hour, you'll need to overdrive it to the tune of about 16-22V (it would require some experimentation to find a sweet spot of over-drive to bulb life ratio).

In theory, it should be capable of over 2000 bulb lumen with some useful bulb life left on the table.
