We first want to try LED bulb with E26/E27 socket to directly replace tungsten bulb on a existing substation building.
Thank you guys, really appreciated.
I have found this video on youtube, there is a comment below about someone who did try it at 125VDC and it is working on that particular model... still need a manufacturer with datasheet to make sure we can specify it on a project... if it is european I think...

This lighting circuit is fed by a huge 125V DC battery, the size of this battery is calculated with the load of these 100watts bulb,
By replacing these light with LED, we...
