Ballast recommendations for HID headlights?

Well they're not up next on the list but they're on the list for sure, Morimoto D2S 4.0 with demon eyes and an Apollo 3.0 shroud. I'm just thinking I've heard stories of cheap ballasts doing a poor job of balancing the power with more light power when you step on the gas. I want a good safe ballast with even power. Any recommendations?

Also if you want you can follow me as I do stuff on my build on my YouTube channel, thanks to everyone who responds!

There’s a lighting sub forum, might post in there for more responses.

 

I just bit the bullet and went with OEM Denso ballasts. I had numerous Morimoto ballasts crap out on me. Buy once, cry once.

 

Nothing wrong with oem. Always stick to oem.
