I have 12 core and coils, but wanted to run an incompatible Sunpulse bulb. Their number one recommendation was the Phantom.
That is what I got and it is more than I expected. But as it is the only one I own there is no comparison to make.
I always understood the digital ballasts would fire any bulb rated digital, be it HPS or HID.
Warnings all over my instructions about don't use bulbs not rated digital, didn't see any exceptions noted. An M59 probe start bulb will physically break in an electronic ballast is the for instance given.
