Different Brand HID bulbs

[BriTess]

Ive got a Kelvin Hid kit with 5000k bulbs and would like to buy a set of DDM 6000k bulbs as a backkup set mainly because the Kelvin bulbs are $80 per pair while DDM are $15. Will I be able to use the DDM bulbs with the Kelvin ballasts?
Thanks

I used tech one bulbs with ddm ballast . Should be same connectors but I'm not 100% sure
